Cooking for One (or Two): Small-Batch Portions That Make Sense

Most recipes are written for four. Halve them and they usually still work — but cook them in the same pans and they fail: the sauce evaporates to nothing, the potatoes burn on the bottom of a huge pot, and the leftovers pile up until they die in the fridge. Cooking for one or two is not "fewer ingredients". It is a different set of physics: less mass, more surface, faster evaporation. Once you accept that, small-batch cooking gets easy — and cheap.

Why small batches go wrong

• Evaporation. A wide pan evaporates the same per minute whether it holds two cups or half a cup. Halve a recipe and keep the pan, and you lose a third of your sauce before it thickens.
• Pan geometry. A 28 cm pan with a single chop gives the meat a huge cold zone — it steams instead of searing. Match the pan to the food, not the recipe.
• Uneven scaling. Leavening, salt, and spice don't always scale linearly in small amounts — half a teaspoon becomes "a pinch".

The right kit for one or two

• An 18–20 cm frying pan (the single most useful pan in a small kitchen) and a 16 cm saucepan with a lid.
• A half-sheet or quarter-sheet pan for roasting — a full sheet pan is why single-portioned vegetables burn at the edges.
• A digital scale. Portions for one are small enough that a "generous pinch" of salt is a real difference.

Try it — pick a staple and set your servings:

Scaling rules that hold

1. Time barely changes. A single chicken breast cooks almost as long as two — don't halve the minutes, check the temperature.
2. Evaporation is the enemy. Cook sauces in a small, narrow pot and keep a lid handy. Add liquid back, not flour.
3. Salt and acid scale with weight — 1% salt is 1% salt whether you cook 200 g or 2 kg. Spices and aromatics scale slightly under: one clove of garlic does not become three because you doubled the recipe.
4. Round the numbers so they stay usable: half a tablespoon, one egg, one can of tomatoes — then adjust by tasting.

Cook once, eat twice — deliberately

The smartest small-batch move is not cooking less; it is cooking components. Roast a single tray of vegetables and use them tonight in a bowl, tomorrow in a frittata, the day after in a sauce. Cook one batch of rice and use it three ways. Component cooking gives the economy of batch cooking without the fridge full of identical leftovers.

The key takeaway: small batches fail from big pans, not small portions. Match the pan to the food, weigh the small stuff, scale salt by weight, and cook components — not just dishes.

For the full system behind planning meals for a week, the 3-list meal-planning system is the framework, and scaling recipes properly covers rounding, eggs, and the edge cases when you do cook for four.
