The best recipe apps for cooking for one or two

Published October 10, 2026 Last checked October 10, 2026

What’s the best recipe app for cooking for one or two?

For precise scaling down, Pestle and Crouton are the strongest. Pestle lets you type an exact serving count and tidies small units, and Crouton can scale from the one ingredient you actually have, like a single chicken breast. Paprika’s pantry tracks expiration dates, which helps when half a bunch of herbs is the real problem. Sous Chef helps with the part multipliers skip: ask it to make a recipe “for one,” and it can change the steps too. That covers the smaller pan, the half egg, and the shorter reduction.

Cooking small isn’t just dividing by four. Most recipes are written for four to six people, and the arithmetic is the easy part. The hard parts are the leftovers: half an egg, a third of a can of tomatoes, a pan that’s now too big, and the five other servings that still have to go somewhere. That’s what this comparison focuses on.

The four problems with small-batch cooking

1. Awkward amounts. A quarter of a recipe that calls for 1 egg, 3/4 cup of milk, and 1 can of beans leaves you with a quarter egg, 3 tablespoons of milk, and a quarter can. We cover the measuring tricks in how to halve a recipe with one egg. The short version: whisk the egg and weigh about 25 grams for half of a large egg, per King Arthur Baking.
2. Equipment that doesn’t shrink. Half the batter in the original pan bakes thin and fast. Half a sauce in the original skillet reduces faster and can scorch.
3. Ingredients you can’t buy small. Celery, herbs, and cream come in household sizes. What you don’t use goes off.
4. Leftovers. Sometimes cooking two or four servings and eating them over several days is the right call, but only if they’re stored safely.

Which apps help with which problem

Claims below come from each app’s US App Store listing (including release notes) or its company’s site, checked October 10, 2026.

App by app

Pestle: the cleanest scale-down math

For cooking small, how the numbers display matters as much as the math. A quartered recipe that shows “0.25 tbsp” is technically right and useless at the stove. Pestle’s release notes describe automatic unit conversion above a threshold, plus newer units like cans, sheets, and cloves. That helps a quarter-batch read like measurements you can actually use. The free plan keeps 15 recipes, which can be enough for a solo cook with a short rotation.

Crouton: scale to the one thing you bought

Crouton’s scaling “by a selected ingredient” fits single-person shopping well. Buy one 250 g pork chop for a recipe written for 1 kg, scale by that ingredient, and everything else shrinks to match. Crouton also has meal planning and a grocery list, so a cook-twice-eat-four-times week is easy to plan.

Paprika and Recipe Keeper: use up what’s left

These two help with the problem after cooking. Paprika’s pantry tracks “quantities, purchase dates, and expiration dates,” and its search works by ingredient, so the half-bunch of cilantro can lead you to tomorrow’s dinner. Recipe Keeper’s listing suggests the same idea: search your own recipes by the leftovers in your fridge. Both scale and convert units, and neither listing says the steps change when the servings do.

Recipe Scaler: a calculator built for this

The free Recipe Scaler app is a two-column calculator: enter the original quantities, then how much you have of any one ingredient. It’s pitched at exactly this situation. It doesn’t save recipes or adjust cooking steps, but it costs nothing.

Sous Chef: when the steps need to shrink too

Sous Chef treats “make this for one” as an edit, not a multiplier. The model returns typed changes that the server validates. Those changes can cover ingredient lines, like turning “2 eggs” into “1 egg” or “1 can chickpeas” into “half a can (save the rest).” They can also cover the steps that reference them, like “use a 9-inch skillet” becoming “use a small 8-inch skillet,” or a note to start checking the bake earlier. Changed lines are marked Edited, the original is kept so you can undo, and invalid edits are rejected instead of silently applied.

It’s not the full solution for cooking alone: there’s no pantry, no meal planner, and no grocery list, and it’s iPhone-only. The model can also be wrong about a quantity, so read the edited lines before you cook, especially in baking. Where it fits is the moment a recipe for six is open and you want a version for one without redoing the math and the method yourself.

Scale to two, then plan for leftovers

Sometimes the best small-batch recipe is a normal-sized one. Stews, braises, chili, and grain salads hold up well, and many get better on day two. Halving a big lasagna can mean an awkward pan and an underbaked middle. Cooking it whole and storing portions can be easier. If you do:

• Refrigerate within 2 hours of cooking, and divide large amounts into shallow containers so they cool quickly.
• Use refrigerated leftovers within 3 to 4 days, or freeze them. Frozen leftovers stay safe but lose quality over time. USDA suggests 3 to 4 months for best quality.
• Reheat to 165°F, checked with a food thermometer, and bring sauces, soups, and gravies to a rolling boil.

All three come from USDA FSIS’s leftovers and food safety guidance. In Sous Chef you could ask, “make this for two with two extra portions to freeze.” But the storage rules are yours to follow, not the app’s.

Pan size when you halve

When you cut a baking recipe in half, the pan matters more than the clock. Half the batter in the original pan comes out thinner and bakes faster. Halved batter in a pan with about half the area keeps roughly the original depth and timing. King Arthur Baking’s guide to pan sizes explains why batter depth drives baking time. This section is desk-researched, not a kitchen test. Start checking a halved bake several minutes early and use a doneness test, like a toothpick or an internal temperature, rather than the original time. For the timing side, see does cooking time change when you double a recipe, which works the same way in reverse.

Which should you use?

• You want exact small numbers and a recipe library: Pestle.
• You shop for one and scale from what you bought: Crouton.
• Wasted ingredients are your real problem: Paprika’s pantry, or Recipe Keeper’s leftover search.
• You need quick math and nothing else: Recipe Scaler.
• You want the method rewritten for one or two, with the original kept: Sous Chef. See also the best recipe scaling apps for iPhone for a closer look at how each app scales.

Common questions

What’s the easiest way to cut a recipe for four down to one?

Divide every ingredient by four, then fix what division can’t: use a smaller pan, whisk and weigh partial eggs, and start checking doneness early. Apps like Pestle and Crouton handle the arithmetic. Sous Chef can also rewrite the pan and timing steps, which you should still read before cooking.

How do I use half an egg when halving a recipe?

Crack the egg, whisk the white and yolk together, and weigh out about 25 grams, which is half of a typical large egg without its shell, per King Arthur Baking. Use the rest in scrambled eggs or an egg wash.

Which recipe app helps reduce food waste when cooking for one?

Paprika’s pantry tracks ingredient quantities and expiration dates, and its search finds recipes by ingredient. Recipe Keeper suggests searching your own recipes for ones that use up leftovers. Crouton can scale a recipe to the amount of one ingredient you already have.

How long do leftovers last in the fridge?

USDA FSIS says to refrigerate leftovers within 2 hours and use them within 3 to 4 days, or freeze them. Frozen leftovers keep best for about 3 to 4 months. Reheat to 165°F, checked with a food thermometer.

Does halving a recipe halve the cooking time?

Usually not. Time follows the thickness of the food and the depth of the pan, not the number of servings. A halved batter in a smaller pan of similar depth bakes in about the original time. In the original pan it’s thinner and finishes sooner, so check early.

Is Sous Chef good for cooking for one?

It helps when you want a recipe rewritten for one or two, including steps like pan size, with the original kept and every change marked Edited. It doesn’t have a pantry, meal planner, or grocery list. It’s free to download and try; heavier AI use may need a subscription later.
