Batch cooking advice is almost always written for families. Make a huge pot of chilli, eat it all week. That works if you have four people sharing the pot. When it's just you, eating the same chilli on Monday, Tuesday, Wednesday, Thursday, and Friday is a good way to never want to see chilli again.
The shift that makes batch cooking work for one person is cooking components rather than complete dishes. A full chicken curry reheated five times in a row becomes oppressive. But a batch of cooked chicken, separated and stored, becomes: a rice bowl on Monday, a wrap on Wednesday, the base of a soup on Friday. Same effort, three different meals.
Useful components to batch cook:
This is a realistic session for one person, not a full day of cooking:
Total active time: about 20 minutes. Output: 3-4 dinners and several lunches, all with different combinations. Store everything separately in labelled containers and assemble meals rather than reheating full dishes.
Fridge (4 days): Cooked rice and grains, roasted veg, cooked chicken, most sauces, hard-boiled eggs (unpeeled last longer)
Freezer: Soup, curry, chilli, cooked lentils and beans, individual portions of sauce. Freeze in small portions - 200ml containers are ideal for sauces, 300-400ml for soups and stews. Cooked chicken thighs freeze fine for up to 3 months.
The key is single-portion freezing. A large batch frozen as one block means you're committing to eating all of it when you defrost it. Single portions mean you can pull out exactly one dinner.
Two practical rules: don't store more than two portions of any one thing in your fridge at once, and vary the format even when the base ingredient is the same. Yesterday's roasted chicken in a rice bowl. Tonight's leftover rice in a fried rice with egg and frozen veg. The chicken in tomorrow's soup with whatever needs using up.
Eggs are the best rescue ingredient in a solo kitchen. When you have random leftovers that don't obviously go together, a good omelet or a frittata-style baked egg dish can incorporate almost anything. The eating well alone guide covers more of these fast combination meals.
Some dishes are genuinely worth making in a proper batch and freezing in single portions because they either take a while or taste better after sitting:
