How to Halve a Recipe: Eggs, Pans, Times and Tricky Measurements
How to cut a recipe in half: halving measurements, half an egg, smaller pans, adjusted baking times, and a handy chart for awkward amounts.

Halving a recipe is perfect for cooking for one or two, testing a new dish or avoiding a week of leftovers. Most ingredients halve easily; a few need tricks.
Halving chart for awkward amounts
| Original | Half |
|---|---|
| 1 cup | ½ cup |
| ¾ cup | 6 tbsp |
| ⅔ cup | ⅓ cup |
| ½ cup | ¼ cup |
| ⅓ cup | 2 tbsp + 2 tsp |
| ¼ cup | 2 tbsp |
| 1 tbsp | 1½ tsp |
| 1 tsp | ½ tsp |
| ½ tsp | ¼ tsp |
| ¼ tsp | ⅛ tsp (a pinch) |
Even easier: use grams and divide by two. See cups to grams.
Half an egg
Crack the egg into a bowl, beat it, and use half by weight (a large egg is about 50 g without shell, so use about 25 g) or about 2 tablespoons. Save the rest for scrambled eggs.
If the recipe has 3 eggs, use 1 whole egg plus about half of a beaten egg.
Pans
Halving the ingredients but keeping the same pan makes food thinner, which cooks faster and can dry out.
- Cakes: use a pan with about half the area (a 23 × 33 cm / 9 × 13 in recipe → 20 × 20 cm / 8 × 8 in pan).
- Casseroles: smaller dish, similar depth.
- Sauces: smaller saucepan, or the liquid will evaporate too fast.
Cooking times
- Stovetop: times are often similar; small quantities may cook a little faster.
- Baking: with a smaller pan of the same depth, times are similar or slightly shorter; check 5–10 minutes early.
- Roasts: a smaller roast cooks faster; use a thermometer. See meat temperature chart.
Seasoning
Halve spices and salt, then taste and adjust.
Let the app do the math
In SmartChef AI, change the servings on a recipe (for example from 4 to 2) and the ingredient amounts update. For egg-heavy baking recipes, ask Cook AI how to handle the eggs. See also how to scale a recipe and dinner ideas for two.
Recipes that are hard to halve
- Yeast breads: usually fine, but small doughs are harder to knead in a mixer.
- Soufflés and sponges: depend on egg structure; halving works, but pan size matters a lot.
- Recipes with 1 egg in a small batch: the egg trick above helps.
- Slow-cooker recipes: a half-full slow cooker cooks faster; check earlier.
Or cook the full recipe and freeze half
For soups, stews, sauces and casseroles, cooking the full amount and freezing half is often easier than halving.
Frequently asked questions
How do you halve 1/3 cup?
Use 2 tablespoons plus 2 teaspoons.
How do I halve a recipe with 1 egg?
Beat the egg and use about half (roughly 25 g or 2 tablespoons).
Does halving a recipe change baking time?
Slightly. Use a smaller pan to keep the depth similar, and start checking early.
