How to Scale Down a Recipe for One (Cooking Conversion Guide)

Half a can of beans going fuzzy in the fridge. A 9x13 pan for one dinner. One egg you cannot split. That is life when you never scale down a recipe written for six.

Nearly every recipe is written for four to eight people. Cutting one down is simple math, but the math is only half the job, because eggs, pan sizes and cooking times do not shrink in a straight line. Below is our full method, with the conversion charts we keep taped inside a cabinet door.

The short version:

• Do the math once: divide the servings you want by the servings the recipe makes, multiply every ingredient by that number, and turn awkward amounts into tablespoons or grams with the chart below.
• Split eggs by weight: a large egg is about 50 grams out of the shell, so half is about 25 grams.
• Shrink the pan, not the heat: use a pan with about half the surface area, keep the oven temperature the same, and start checking for doneness at about two-thirds of the original time.

How to Scale Down a Recipe in 5 Steps

Here is our method for any recipe, from a weeknight soup to a cake.

1. Find your scale factor. Divide the servings you want by the servings in the recipe. One serving from a 4-serving recipe is 1 ÷ 4 = 0.25. Two servings from a 6-serving recipe is 2 ÷ 6, or one-third.
2. Multiply every ingredient. Write the new amount next to each line in pencil before you start. Do not do the math in your head while the pan heats up.
3. Convert awkward amounts. “3/8 cup” is hard to measure. “6 tablespoons” is easy. Use the charts below to turn odd fractions into spoons, or switch to grams.
4. Choose a smaller pan. A half batch in a full-size pan spreads thin, burns at the edges and dries out. Match the pan to the new amount.
5. Watch the clock, not the recipe. Keep the same oven temperature, but check early. Use a thermometer for meat, and the usual signs (a clean toothpick, golden edges) for baking.

Write the scaled version on a card so you only do the math once. Our guide on how to stock a small kitchen for solo cooking covers the rest of the setup.

Recipes for One or Two: Pick the Right Scale Factor

Not every recipe should be cut to exactly one serving. Here is how we decide.

• Cut to one serving for things that do not keep well: fried eggs, stir-fries, crispy fish, salads with dressing, fresh pasta dishes.
• Cut to two servings for things that taste just as good the next day: soups, curries, chili, grain bowls, roasted vegetables. Eat one tonight and pack the other for lunch.
• Keep the full recipe for long braises, stocks and anything that takes hours. The work is the same for four servings as for one, so make it once and portion it.

Two servings is often the sweet spot. Many recipes for one or two work best at a factor of 0.5, because halving keeps the math clean. Cooked leftovers keep 3 to 4 days in a fridge at 40°F or below, so a second serving is never wasted. Our easy meal prep ideas for one person show how to plan around that.

Recipe makes	For 1 serving, multiply by	For 2 servings, multiply by
2 servings	1/2	1 (no change)
4 servings	1/4	1/2
6 servings	1/6	1/3
8 servings	1/8	1/4
12 servings	1/12	1/6

At 1/8 or 1/12, the math gets fiddly. Cut those recipes to a quarter or a third instead and keep the extra servings.

How to Cut a Recipe in Half: The Chart

This is the how to cut a recipe in half chart we reach for most. It starts from the four basic facts every cook should know:

• 1 cup = 16 tablespoons
• 1 tablespoon = 3 teaspoons
• 1/4 cup = 4 tablespoons
• 1/3 cup = 5 tablespoons + 1 teaspoon

Everything in the table comes from those four lines.

Original amount	Half	Quarter
1 cup	1/2 cup	1/4 cup
3/4 cup	6 tbsp (1/4 cup + 2 tbsp)	3 tbsp
2/3 cup	1/3 cup	2 tbsp + 2 tsp
1/2 cup	1/4 cup	2 tbsp
1/3 cup	2 tbsp + 2 tsp	1 tbsp + 1 tsp
1/4 cup	2 tbsp	1 tbsp
1/8 cup (2 tbsp)	1 tbsp	1 1/2 tsp
1 tablespoon	1 1/2 tsp	3/4 tsp
1 teaspoon	1/2 tsp	1/4 tsp
1/2 teaspoon	1/4 tsp	1/8 tsp (a dash)
1/4 teaspoon	1/8 tsp (a dash)	1/16 tsp (a pinch)
1/8 teaspoon	1/16 tsp (a pinch)	1/32 tsp (a smidgen)

For liquids, remember that 1 cup is 8 fluid ounces, and 1 fluid ounce is 2 tablespoons. So half of 3/4 cup of broth is 3 fluid ounces. If you work in quarts and ounces often, our page on how many ounces are in a quart has the bigger conversions.

The Spoons and Cups That Make the Chart Easy

Most basic sets stop at 1/4 teaspoon and skip 1/2 tablespoon. That is exactly where halved recipes land. The Spring Chef Magnetic Measuring Spoons Set of 8 fixes both gaps. It runs from 1/8 teaspoon to 1 tablespoon, includes a 1/2 tablespoon, and each spoon has a narrow end that fits inside a spice jar.

For the smallest amounts, add the Norpro Mini Stainless Steel Measuring Spoons. The five spoons are a tad (1/4 tsp), a dash (1/8 tsp), a pinch (1/16 tsp), a smidgen (1/32 tsp) and a drop (1/64 tsp). They matter most for baking soda, cayenne and cloves, where a little too much changes the whole dish.

For cups, a set with 2/3, 3/4 and 1/8 cup saves a lot of counting. The U-Taste Stainless Steel Measuring Cups Set of 7 has all seven sizes from 1/8 cup to 1 cup, with the size engraved so it never rubs off. For small splashes of liquid, the OXO Good Grips Mini Angled Measuring Cup holds 2 ounces and is marked in teaspoons, tablespoons and milliliters. You read it from above, so 3 tablespoons of soy sauce takes one pour instead of three spoons.

All of these nest in one small drawer slot. Our guide to organizing kitchen drawers in a small kitchen shows how to give them a home.

How to Scale Down a Recipe With Fractions

When a number is not on the chart, do the fraction math. It is easier than it looks.

To halve a fraction, double the bottom number. 3/4 becomes 3/8. 2/3 becomes 2/6, which is 1/3. 1/3 becomes 1/6.

To quarter a fraction, multiply the bottom number by 4. 3/4 becomes 3/16. 1/2 becomes 1/8.

To take a third, multiply the bottom number by 3. 3/4 becomes 3/12, which is 1/4.

Then turn the result into tablespoons. Multiply the cup fraction by 16:

• 3/8 cup × 16 = 6 tablespoons
• 3/16 cup × 16 = 3 tablespoons
• 1/6 cup × 16 = 2 2/3 tablespoons, which is 2 tablespoons + 2 teaspoons

If the answer is still a strange fraction of a tablespoon, multiply that part by 3 to get teaspoons. Two-thirds of a tablespoon is 2 teaspoons.

Mixed numbers work the same way. Turn 1 1/2 cups into 24 tablespoons first, then divide. A third of that is 8 tablespoons, or 1/2 cup. Doing it in tablespoons avoids most mistakes.

Scaling to a Third

A third of a 6-serving recipe gives you two servings. The amounts you will hit most:

• 1 cup → 1/3 cup
• 3/4 cup → 1/4 cup
• 1/2 cup → 2 tbsp + 2 tsp
• 1/4 cup → 1 tbsp + 1 tsp
• 1 tablespoon → 1 teaspoon
• 1 teaspoon → a heaping 1/4 teaspoon

Weigh Instead of Measure: The Easiest Way to Scale Down Ingredients

The best way to scale down ingredients in a recipe is to stop using cups. Grams divide cleanly. Half of 250 grams is 125 grams, with no fractions and no leveling.

A digital scale is the single tool we would buy first for small-batch cooking. The Escali Primo Digital Kitchen Scale is a compact, budget pick that weighs in 1-gram steps up to 11 pounds. It stands on its edge in a cabinet. Big bowls hide the screen on most scales. The OXO Good Grips 11-Pound Scale With Pull-Out Display solves that. It costs more, but the display slides out from under the bowl.

Press “tare” (it resets the scale to zero) after each ingredient, and weigh everything into one bowl. A scale is also on our list of small kitchen gadgets worth buying when you cook for one.

Common Weights for Scaling

Ingredient	1 cup	1/2 cup	1 tablespoon
Water, milk, broth	240 g	120 g	15 g
All-purpose flour (spooned and leveled)	120 to 130 g	60 to 65 g	about 8 g
Granulated sugar	200 g	100 g	12.5 g
Butter	227 g (2 sticks)	113 g (1 stick)	14 g
Large egg, beaten	about 50 g per egg	about 25 g per half egg	about 17 g

Butter is the easiest one to scale. One stick is 1/2 cup, 8 tablespoons or 113 grams, and the wrapper is marked in tablespoons. Cut along the lines and you are done.

For meat, a scale shows you how much you actually have. A “pound of chicken” in a recipe for four is about 4 ounces per person. Our guide on how much a chicken breast weighs explains why one supermarket breast is often two portions.

How to Halve an Egg (and Split Other Whole Ingredients)

Eggs are where most people get stuck. You cannot crack half an egg, but you can measure one.

1. Crack the egg into a small cup and beat it with a fork until the white and yolk are fully mixed.
2. Weigh it. A large egg is about 50 grams out of the shell.
3. Pour off what you need. Half an egg is about 25 grams, or about 1 1/2 tablespoons.

No scale? A beaten large egg is a little over 3 tablespoons. Use 1 1/2 tablespoons for half and about 2 1/4 teaspoons for a quarter. For a third, use 1 tablespoon.

You can also split by part. The white of a large egg is about 2 tablespoons and the yolk is about 1 tablespoon. If a recipe calls for 3 eggs and you are halving it, use 1 whole egg plus 1 yolk, or 1 whole egg plus half of a beaten second egg. In most cookies and quick breads, either works.

What to do with the leftover half: cover it and put it in the fridge at 40°F or below. Use it within 2 days, in scrambled eggs, an egg wash or tomorrow’s half batch. You can also freeze beaten egg in small portions. The Souper Cubes 2-Tablespoon Trays hold one half-egg portion per cavity, with a lid, and the same tray works for leftover tomato paste or pesto. Thaw frozen egg overnight in the fridge and cook it fully.

Other Whole Ingredients

• Lemons and limes: a medium lemon gives roughly 2 to 3 tablespoons of juice. Our guide on how much juice is in one lemon has the full breakdown. Wrap the cut half and use it within a few days.
• Onions: half a medium onion is about 1/2 cup chopped. Wrap the other half tightly and keep it in the fridge.
• Yeast: one packet holds 2 1/4 teaspoons. Half a packet is 1 teaspoon plus 1/8 teaspoon. Fold the open packet closed and keep it in the fridge.

How to Adjust Pan Size When Halving a Recipe

This is the step people skip, and it causes most half-batch failures. A half batch in the original pan spreads too thin. It cooks fast, dries out and burns at the edges.

The rule is simple: use a pan with about half the surface area. Area is length times width for square pans. For round pans, it is 3.14 times the radius squared (the radius is half the width).

Keep the batter or food at about the same depth as the original. Then the bake time stays close, and only small tweaks are needed.

Original pan	Area (sq in)	Half batch	Quarter batch
9 x 13 in baking dish	117	8 x 8 in square (64)	6 in round (28) or a loaf pan
9 x 9 in square	81	8.5 x 4.5 in loaf (38)	Two 6 oz custard cups
8 x 8 in square	64	6 in round, 2 in deep (28)	One mini loaf pan
Half sheet, 18 x 13 in	234	Quarter sheet, about 13 x 9 in (117)	8 x 8 in square or a toaster oven pan
Two 8 in rounds (layer cake)	100 total	Two 6 in rounds (57 total)	One 6 in round
One 9 in round	64	One 6 in round (28)	Two 6 oz custard cups
9 x 5 in loaf	45	Two mini loaf pans	One mini loaf pan
12-cup muffin tin	12 cups	Fill 6 cups	Fill 3 cups

When you use only part of a muffin tin, pour a little water into the empty cups. It keeps the empty metal from scorching and helps the tin heat evenly.

The Small Pans We Recommend

For sheet-pan dinners, the Nordic Ware Natural Aluminum Quarter Sheet is the pan we would reach for first. At about 13 x 9 inches, it holds a half batch of a half-sheet recipe at the right depth. It also fits in many larger toaster ovens. Our guide to compact baking sheet and pan sizes lists which sizes fit which ovens.

For halved casseroles, lasagna and brownies from a 9 x 13 recipe, use an 8-inch square. The Pyrex Deep 8-Inch Square Baking Dish With Lid has taller sides than a standard 8 x 8, so a layered lasagna fits. The lid lets the leftovers go straight into the fridge.

For cakes, the Fat Daddio’s 6 x 2 Inch Round Cake Pans, 2 Piece Set is the swap for a two-layer 8-inch cake made at half size. The pans are 2 inches deep with straight sides, so the layers come out even.

For quick breads like banana bread, the USA Pan Nonstick Mini Loaf Pan Set of 4 gives you four separate pans about 6 x 3.5 inches each. A half batch of a 9 x 5 loaf fills two of them about two-thirds full. Bake one and freeze the other loaf whole.

For single-serving crisps, pot pies and baked oatmeal, use Pyrex 6-Ounce Custard Cups. The glass cups go from oven to fridge and stack inside each other. A quarter of a 9-inch fruit crisp fills about two of them.

Our list of the best bakeware for small kitchens covers more sizes, and our space-saving baking tool essentials shows how to store them.

Stovetop Pans Matter Too

The same rule applies on the stove. Half a stir-fry in a 12-inch skillet spreads thin and the oil burns in the empty spots.

For one or two servings, an 8-inch skillet is the right size. The Lodge 8-Inch Pre-Seasoned Cast Iron Skillet sears one steak or chop and goes into the oven. For eggs, the Tramontina Professional Fusion 8-Inch Nonstick handles a two-egg omelet without sticking.

For halved soups, sauces and grains, the Tramontina Tri-Ply Clad 2-Quart Covered Saucepan is the right size. For a half-batch braise or chili, the Lodge 3-Quart Enameled Cast Iron Dutch Oven keeps the liquid deep enough to cover the meat. Our full guide to the best cookware sizes for cooking for one goes pan by pan.

Do Cooking Times Change When You Halve a Recipe?

Yes, but not by half. Cooking time depends on how thick the food is, not how much of it there is. Heat has to travel from the outside to the center, and that distance is what sets the clock.

Baking

• Same depth in a smaller pan: the time drops a little, usually 10 to 25 percent. Start checking at about two-thirds of the original time.
• Thinner layer (same pan, half batter): it bakes much faster and dries out. Avoid this, or check at half the original time.
• Deeper layer (pan too small): the center lags behind the edges. Lower the oven by 25°F and bake longer, checking often.
• Keep the oven temperature the same in all other cases. Do not halve the temperature.

Muffins, cookies and rolls are the easy case. Each one is the same size as before, so the time barely changes. Bake 6 cookies at the same time and temperature as 24. They may finish a minute or two early because the oven recovers faster with less cold dough inside.

Small ovens heat fast and run hot near the elements. If you bake half batches in a toaster oven, our guide to the best small ovens and toaster ovens for baking covers how to keep them even. Our tips on how to bake in a small kitchen without extra counter space help with the prep side.

Roasting Meat and Vegetables

One chicken breast takes about as long as four, because each one is the same thickness. A whole 3-pound chicken roasts faster than a 6-pound one, because it is thinner through the middle.

Do not guess. Use an instant-read thermometer and cook to these temperatures:

• Chicken and turkey: 165°F
• Ground beef and pork: 160°F
• Pork chops and roasts, steaks, fish: 145°F (rest 3 minutes for pork and beef)

The ThermoWorks ThermoPop 2 reads in a few seconds and fits in a utensil drawer. It is the tool that makes scaled-down meat recipes safe. Our guide on how long chicken lasts in the fridge covers what to do with the rest of the pack.

Vegetables follow the same rule. Spread them in one layer on a smaller pan, and the time stays about the same. Crowd them and they steam instead of brown.

Stovetop

• Pasta and grains: the cook time stays the same. A smaller pot of water boils sooner, which saves a few minutes and some energy.
• Rice: keep the same rice-to-water ratio and the same cook time, but use a small pot. In a wide pot, a half batch can lose too much water and stick. Our guide to cooking rice in a rice cooker covers small batches in a cooker.
• Soups and sauces: they reduce faster in a wide pot because there is more surface for each cup of liquid. Use a smaller pot, or add a splash more liquid near the end.
• Searing and sautéing: the time per piece stays the same. You may need a little more than half the oil to coat the pan.

If you only have two burners, halved recipes are a big help. Our guide on how to cook a full meal with only two burners shows how to time the parts.

Pressure Cookers, Slow Cookers and Air Fryers

• Pressure cooker: the time under pressure stays the same for same-size pieces. It reaches pressure faster with less food. But the minimum liquid does not halve. Check your manual for the minimum and never go below it. A smaller pot like the Instant Pot Duo Mini 3-Quart suits half batches better than a 6-quart. Our explainer on what an Instant Pot is covers how the timing works.
• Slow cooker: these work best about half to two-thirds full. A half batch in a big slow cooker can cook too fast and scorch. Use a smaller cooker, or check a few hours early.
• Air fryer: a smaller load cooks faster because the hot air reaches every piece. Check 2 to 4 minutes early.
• Microwave: less food heats faster. Start at a little more than half the original time, stir, and add time in short bursts.

Scaling Seasoning, Leavening and Liquids

Most ingredients scale in a straight line. A few need care.

Salt and spices: halve them exactly, then taste before serving. Strong spices like cayenne, cloves and chipotle are easy to overdo in small amounts, so use the mini spoons. If you keep many spices for half recipes, our spice storage ideas for small kitchens keep the jars easy to reach.

Baking soda and baking powder: these scale exactly with the math. The problem is measuring 1/8 or 1/16 teaspoon by eye. Level each spoon with a knife. Too much leavening gives a bitter, soapy taste and a cake that rises and then sinks.

Oil for the pan: a pan needs a thin coat no matter how much food is in it. Use enough to coat your smaller pan, which is often a bit more than the halved amount.

Liquids that cook down: for soups, braises and rice, start with the halved amount. Keep a little extra broth or water nearby, because a small batch can dry out faster.

Thickeners: cornstarch and flour scale exactly. If you run out, our guide to what to use instead of cornstarch lists swaps that work in small amounts.

Canned and Packaged Ingredients: What to Do With the Other Half

Plan for the other half before you open anything.

• Beans: a 15-ounce can gives about 1 1/2 cups drained. Half is about 3/4 cup. Put the rest in a covered container and use it within 3 to 4 days.
• Tomato paste: most recipes use a tablespoon or two. Freeze the rest in tablespoon portions.
• Cream cheese: the extra block freezes for cooking, and our guide on whether you can freeze cream cheese explains how it changes.

Never store leftovers in an open can. Our guide to the best airtight food storage containers include small half-cup sizes. Our guide on how to organize a small fridge keeps them in sight so they get used.

What Recipes Don’t Scale Down Well?

• Deep frying: the oil has to be deep enough to float the food, no matter how much you fry. Use an air fryer or shallow-fry in a small pan.
• Candy, caramel and jam: a small batch is too shallow for a candy thermometer to read, and the temperature climbs fast. Make the full batch.
• Stock and long braises: the time and the bones do not shrink. Make the full recipe and portion it.
• Whole roasts and whole birds: you cannot buy half a turkey easily. Roast a single bone-in chicken thigh or a small pork tenderloin instead.
• Yeast bread: a stand mixer hook spins over a small dough without kneading it. Knead a half batch by hand.
• Whipped egg whites and cream: one egg white is too little for a stand mixer whisk to reach. Use a hand mixer or a whisk. Our guide to the best hand mixers covers compact options.
• Recipes with one egg: a quarter batch needs a quarter of an egg. Weigh it, or cut to a half batch instead.

Most everyday cooking scales without trouble: stir-fries, pasta, salads, soups, curries, casseroles, muffins, cookies and most quick breads.

Set Up a Small-Batch Kit in One Drawer

Keep the scale, spoons, mini measures and thermometer together in one shallow drawer or bin, with this chart taped inside a cabinet door. When the tools are in one place, scaling down becomes the easy choice.

Small pans store well too. A quarter sheet, an 8-inch square and two 6-inch rounds nest together and stand on edge. Our guide to how to store pots and pans in a small kitchen shows how. Smaller pans and smaller batches also use less energy; our guide to reducing kitchen energy use in a small apartment explains why.

If you want appliances sized for one, our list of the best small kitchen appliances for cooking for one covers mini rice cookers, small air fryers and compact ovens.

Where Most People Go Wrong Scaling Down a Recipe

• Using the original pan. This is the biggest one. Match the pan to the new amount using the area chart, or the food will dry out and burn.
• Halving the cooking time. Time depends on thickness. Check early, but do not set the timer for half.
• Lowering the oven temperature. Keep it the same unless the food is deeper than before.
• Guessing at half an egg. Beat it and measure. A “small” egg is not half of a large one in most recipes.
• Rounding small amounts to zero. A recipe that needs 1/16 teaspoon of salt still needs that salt. Use the pinch spoon.
• Doing the math mid-recipe. Write every scaled amount down before you start cooking.
• Scaling down a recipe that should stay full size. Stocks, braises and candy are better made in full and portioned out.
• Forgetting the minimum liquid in a pressure cooker. The food scales down, but the minimum liquid does not.
• Leaving leftovers on the counter. Get extra portions into the fridge within 2 hours. Reheat them to 165°F.

Frequently Asked Questions

How do you scale down a recipe for one person?

Divide 1 by the number of servings the recipe makes to get your scale factor, so a 4-serving recipe becomes 0.25. Multiply every ingredient by that number, convert awkward amounts to tablespoons or grams, then pick a smaller pan and start checking for doneness early.

How do you cut a recipe in half with fractions?

Multiply each fraction by 1/2, which doubles the bottom number: 3/4 cup becomes 3/8 cup and 1/3 cup becomes 1/6 cup. Then turn the result into tablespoons, since 1 cup is 16 tablespoons. 3/8 cup is 6 tablespoons and 1/6 cup is 2 tablespoons plus 2 teaspoons.

Do you halve the cooking time when you halve a recipe?

No. Cooking time depends on the thickness of the food, not the total amount. A half batch in a properly sized smaller pan usually bakes 10 to 25 percent faster, and a single chicken breast cooks in about the same time as four. Check early and use a thermometer.

What size pan do you use for half a recipe?

Pick a pan with about half the surface area. An 8 x 8 inch pan replaces a 9 x 13, a quarter sheet replaces a half sheet, and a 6-inch round holds half the batter of a 9-inch round. Keep the batter depth about the same and the bake time stays close.

How do you halve one egg?

Beat the egg in a cup, weigh it, and use half. A large egg weighs about 50 grams out of the shell, so half is about 25 grams, or about 1 1/2 tablespoons. Keep the rest covered in the fridge and use it within 2 days.
