Batch Cooking for Beginners: How to Cook Once and Eat Four Times

Batch cooking means making one big pot of a freezer-friendly meal instead of a single portion, then eating it across several days rather than cooking from scratch each time. A chilli, a curry, a bolognese, a stew: cook it once, eat it three or four times.

That's the whole idea, and it's simpler than most guides make it sound: pick one recipe that freezes well, cook the full pack sizes you'd buy anyway rather than half of them, and portion up what you don't eat today. You don't need new equipment or a free Sunday. You need one meal, a few tubs or freezer bags, and a bit of fridge or freezer space.

What makes a good batch-cooking recipe

Not everything scales up well. Good candidates share a few traits:

• They're sauce- or stew-based: chilli, bolognese, curry, dhal, soup. The liquid protects the texture in the freezer.
• They reheat without going wrong: mince, beans and lentils reheat fine; cream sauces can split, and salad or anything meant to be crisp doesn't survive freezing at all.
• They're built from pantry staples, so buying the full pack size wastes less, even before you've decided how many portions you want.

Rice and pasta are the exception: cook them fresh each time you reheat, rather than freezing them with the sauce. It only takes 10–15 minutes, and the texture holds up far better.

Picking your first one

Start with a single recipe rather than planning a whole freezer's worth in one go. A beef or bean chilli is the easiest first attempt: cheap, forgiving, and made from things most kitchens already use.

The maths that makes it worth it

The saving in batch cooking isn't really about buying in bulk. It's about not wasting the pack you already bought. Here's a real chilli con carne, priced from our own price tracker at Tesco in September 2026:

• Beef mince (20% fat), 500g: £3.25
• Chopped tomatoes, 400g tin: £0.43
• Kidney beans, 400g tin: £0.39
• Plus an onion and a teaspoon of chilli powder from the cupboard: about 20p for the whole pot at Tesco prices, or 5p a portion

That's about £4.27 for a pot that makes four proper portions, or roughly £1.07 each before rice. Add rice (Tesco basmati is £1.79/kg, so about 13p for a 75g portion) and you're at around £1.20 a serving, with the onion and spice included.

Prefer it leaner? Our recipes use 5% fat mince, which is £5.05 for 500g at Tesco. That takes the pot to about £6.07, or roughly £1.65 a serving with rice.

Either way, one ordinary batch sits at the cheap end of the £1.10–2.50 a serving that most of our main meals cost at Aldi prices. That still makes a takeaway look expensive, and all you did differently was not eat it in one sitting.

Storing and reheating it safely

Split it into the portions you'll actually reheat (individual tubs or bags, not one large block that takes half a day to defrost) and get them into the fridge or freezer within one to two hours of cooking. Smaller portions cool faster. Label each one with the date.

The Food Standards Agency's basics:

• Fridge portions: eat them within two days (48 hours), or freeze them
• Defrosting: overnight in the fridge is the safest way
• Reheating: until it's steaming hot all the way through, and only once, so take out one portion at a time

For more detail, the FSA's guide to chilling, freezing and defrosting food safely is a good place to start.

Mistakes that put people off after one try

• Batching something that doesn't freeze well: a cream-based curry or a dish built around fresh salad won't survive, and one bad reheated meal is enough to write off batch cooking entirely
• Freezing it as one block: impossible to defrost just enough for tonight, so it either all gets eaten at once or ends up in the bin
• Only ever cooking the same one: rotate two or three batch-friendly recipes so week three doesn't taste like week one

Where Plan X Prep fits

Batch cooking is built into how Plan X Prep plans a week: some dishes are cooked once and eaten again later in the week. On the cook day, the app tells you how many portions to make and which go in the fridge or the freezer. On leftover days, it tells you which dish you're eating and, if it's been frozen, to defrost it in the fridge the night before. Every recipe in the 1,500+ library has an estimated cost per serving from 2,000+ real supermarket prices, checked monthly: Aldi first, with Tesco, Sainsbury's and Asda filling the gaps.
