Batch Cooking for Beginners: One Sunday, Five Dinners

Batch cooking has an image problem. Search for it and you'll find people with American-sized fridges making forty identical chicken-and-rice boxes. That's not what feeding a UK household on a budget looks like. Real batch cooking is two hours on a Sunday afternoon, three big pots, and a weeknight routine where dinner is a question of reheating, not cooking.

This is the exact plan I give friends who want to start. It produces five family dinners for roughly £15 to £18 of ingredients, uses one oven and two hobs, and fits in the freezer compartment of a normal fridge-freezer. You'll need a big pot, a roasting tin, a frying pan, and containers — old takeaway tubs are perfect and free.

Why batching saves money, not just time

The savings come from three places. First, ingredients get cheaper in bulk: a 2kg bag of onions costs barely more than four loose ones. Second, you waste less — the whole bag of spinach goes into the pots instead of half of it liquefying in the drawer. Third, and biggest, a full freezer is a wall between you and the £25 Friday-night takeaway. The dinner is already made; you just have to remember it's there — which is why an organised freezer is half the battle.

The shopping list

• 2kg onions, a bulb of garlic, 1kg carrots, 2 peppers — around £3.50
• 500g dried red lentils and 2 tins of chickpeas — around £2.30
• 4 tins of chopped tomatoes — around £2
• 1kg chicken thighs (bone-in is cheapest) or 750g beef mince, whichever is better priced — £4 to £5
• Coconut milk, curry powder, smoked paprika, cumin, stock cubes — around £3 if you don't already have them
• A 500g bag of frozen spinach — around £1.20

Everything else — oil, salt, rice and pasta to serve alongside during the week — comes from the store cupboard. If yours is bare, do the £25 cupboard shop first; this plan assumes those basics exist.

The two-hour timeline

1. 0:00 — Oven on at 200C. Season chicken thighs and get them roasting in the tin. Chop all your onions in one go — every pot starts with them.
2. 0:15 — Start pot one: onions, garlic, carrots, then lentils, curry powder, coconut milk and stock. This becomes a big dhal. Lowest heat, stir occasionally.
3. 0:30 — Start pot two: onions, garlic, peppers, smoked paprika, cumin, two tins of tomatoes, chickpeas. This is your chilli-slash-stew base. Simmer.
4. 0:50 — Chicken out. Shred half for pot three; keep the rest whole for dinner one. Pour the roasting juices into pot two — free flavour, never bin it.
5. 1:00 — Pot three: a quick tomato sauce with the remaining tins, shredded chicken stirred through. This is pasta sauce for two nights.
6. 1:20 — Stir frozen spinach into the dhal. Taste everything. Salt, a splash of vinegar or squeeze of lemon where anything tastes flat.
7. 1:40 — Portion into containers. Label everything with contents and date — a freezer full of mystery orange tubs helps nobody.
8. 2:00 — Kettle on. You're done.

The five dinners you just made

Sunday: roast chicken thighs with whatever sides you fancy. Monday: chicken pasta. Tuesday: dhal with rice and a spoonful of yoghurt. Wednesday: the chickpea chilli over jacket potatoes. Thursday: chicken pasta again, or freeze that portion and have the dhal round two — it's genuinely better on day three. Nothing repeats two nights running, and nothing takes more than fifteen minutes of actual evening effort.

Batch cooking isn't about eating the same thing five times. It's about making Tuesday's decision on Sunday, when you still have the energy to make it well.

Cool it, freeze it, and the safety bits

Get cooked food cooled and into the fridge or freezer within a couple of hours — spreading it into shallow containers speeds this up enormously. Anything you'll eat within three days lives in the fridge; the rest goes to the freezer. Defrost overnight in the fridge, reheat until piping hot all the way through, and don't refreeze something you've already defrosted. Rice is the one to respect: cool it fast, fridge it quickly, one day only, reheat once.

Scaling up without burning out

Don't buy fifteen containers and pledge to batch every Sunday forever. Do this plan twice and see how it feels. The most sustainable version for most people is 'cook once, eat twice' — whenever you make anything freezable, double it and bank half. Within a month, the freezer fills itself and Sunday goes back to being Sunday. That habit alone — doubling, not marathon cook-ups — is what actually cuts the food bill long term, and it's the engine behind feeding four for £30 a week.

Adapting the plan to your household

Fully vegetarian version: swap the chicken for two more tins of beans and a block of halloumi or paneer roasted in the tin instead — the timeline doesn't change and the total drops a couple of pounds. Slow cooker owners can hand pot two over entirely: everything in before the school run, stew by teatime, and the cheapest cuts (shin, cheeks, whatever the butcher's counter is quietly discounting) become the best thing you've made all month. Cooking for one or two, halve nothing — cook the full plan and freeze in single portions instead of family ones; the labour is identical and the freezer dividend doubles.

The other lever is the shop itself. This plan is written around what's reliably cheap, but let the reduced section edit it on the day — half-price peppers mean the chilli gets more peppers, and a yellow-sticker chicken means the whole plan just got £2 cheaper. Batch plans should bend to prices, never the other way round.

Start with the two hours, though. There is no version of a cheaper food bill that doesn't begin with one slightly steamy Sunday afternoon and a radio on. Pick a weekend, do the shop on Saturday so Sunday starts at the chopping board, and let the first Tuesday-night reheat convince you of the rest.
