Meal prep is one of the simplest ways to eat well on a budget. You buy fewer, more versatile ingredients, cook them in one go, and waste less because every portion already has a plan. This guide shows you how to plan, which budget staples batch cook best, and how to freeze and portion food safely. Prices change too often to be useful, so we haven’t included any. The principles work in any supermarket.

Plan before you shop
- Check what you already have. Look in the fridge, freezer and cupboards before you write a list. Love Food Hate Waste suggests basing your meal plan on what’s already there.
- Plan around real life. Work out how many lunches and dinners you actually need. Leave a gap for a “use it up” meal, a night out or something from the freezer, rather than planning every single meal.
- Choose two or three base recipes that share ingredients. One bag of onions, one tray of chicken thighs and a few tins can stretch across several different dishes.
- Write the list and stick to it. Buying “just in case” is where both money and food get wasted.
- Cook the right amount. Love Food Hate Waste’s portion calculator helps you work out how much rice, pasta or potatoes to cook for the number of meals you’re making.
Budget staples that batch well
| Staple | Why it works for budget prep | Batch idea |
|---|---|---|
| Dried and tinned pulses (lentils, chickpeas, beans) | Long shelf life; stretch or replace meat | Dahl, bean chilli, chickpea curry |
| Eggs | Quick protein for breakfasts and lunches | Frittata or egg muffins with leftover veg |
| Frozen veg | No waste: use what you need and put the rest back | Stir into curries, sauces, rice and noodles |
| Rice | Cheap, filling base that keeps well dry | Burrito bowls, curry boxes, fried rice |
| Oats | Breakfast that takes minutes to prep | Overnight oats in jars |
| Chicken thighs | Stay juicy when reheated; easy to shred | Traybakes, shredded for wraps and bowls |
| Potatoes | Versatile and freezer-friendly once cooked | Jacket potatoes with chilli; roasted wedges |
| Tinned tomatoes | The base of most batch sauces | Chilli, ragù, shakshuka, soups |
The NHS Eatwell Guide counts fresh, frozen, dried and tinned fruit and veg towards your 5 a day, so you don’t need to buy everything fresh. Beans and pulses are one of the protein foods it suggests eating more of.
One safety note on dried beans: the FSA warns that raw or undercooked red kidney beans contain a natural toxin, and that you should not slow cook raw red kidney beans. Tinned beans are already cooked and ready to use. If you use dried beans, follow the soaking and boiling instructions on the packet.
One shop, five meals: an example plan
This plan is built from one shop of staples. Quantities depend on how many people you’re feeding, so use the portion calculator above.
Shopping list: chicken thighs, red lentils, a tin of chickpeas, two tins of chopped tomatoes, a tin of kidney beans, onions, garlic, a bag of frozen mixed veg, frozen spinach, rice, eggs, oats, plain yoghurt, spices you already have (cumin, chilli, curry powder or paste).
| Meal | Made from | Keep or freeze? |
|---|---|---|
| 1. Chicken and veg traybake with rice | Chicken thighs, onions, frozen mixed veg, rice | Eat in the first two days |
| 2. Red lentil and chickpea dahl | Lentils, chickpeas, onion, garlic, spinach, spices | Freeze portions |
| 3. Chicken and bean chilli | Leftover chicken (shredded), kidney beans, chopped tomatoes, onion | Freeze portions |
| 4. Veg and spinach egg muffins | Eggs, frozen veg, spinach | Fridge for two days |
| 5. Overnight oats | Oats, yoghurt, milk | Make two or three jars at a time |
Cook the traybake and dahl on prep day, and turn some of the chicken into chilli while the oven is still on. That way the oven and hob are only on once.
Every meal here is built around a protein food (chicken, lentils, chickpeas, beans, eggs or yoghurt), so this also works as a protein-rich budget plan. For more ideas, see protein-rich meal prep ideas.
Freezing and portioning safely
The freezer is what makes cheap meal prep work. The FSA advises:
- cool cooked food and put it in the fridge or freezer within one to two hours, dividing big batches into smaller containers so they cool faster
- keep your freezer at around -18°C
- use airtight containers or freezer bags to avoid freezer burn, and label everything
- eat fridge leftovers within 48 hours, or freeze them
- rice: cool it quickly and get it into the fridge or freezer within an hour, and never reheat it more than once
- defrost in the fridge, use defrosted food within 24 hours, and reheat it only once until it’s steaming hot all the way through
Freeze in single portions so you only defrost what you need. The FSA notes that frozen meat is usually best eaten within 2 to 3 months for quality. See our full guide on how long meal prep lasts in the fridge and freezer.
Cutting waste
- Keep an “eat me first” shelf in the fridge for anything close to its date, as Love Food Hate Waste suggests.
- Know your date labels. “Use by” is about safety and “best before” is about quality. The FSA explains the difference in its guide to date labels.
- Freeze before it’s too late. The FSA says you can freeze food right up to midnight on the use-by date.
- Turn leftovers into the next meal. Leftover roast chicken becomes chilli or wraps, and leftover veg goes into egg muffins or soup.
- Don’t keep opened tins in the can. Move the leftovers into a covered container in the fridge.

Frequently asked questions
What’s the cheapest way to meal prep?
Plan a few meals that share ingredients, build them around pulses, eggs, frozen veg and a cheap cut like chicken thighs, cook in one session and freeze single portions. Planning and cutting waste save more than any single ingredient swap.
Is batch cooking cheaper than cooking every day?
It usually helps, because you buy ingredients in useful quantities, use them all up and run the oven once. Love Food Hate Waste highlights batch cooking as a way to use up every ingredient and save both money and time.
Can I meal prep on a budget for one?
Yes. Cook the full recipe and freeze the extra portions, rather than trying to cook tiny amounts. Love Food Hate Waste’s meal planning for one guide covers this.
Can I do cheap meal prep that’s still protein-rich?
Yes. Lentils, chickpeas, beans, eggs, yoghurt and chicken thighs are all protein foods that suit budget batch cooking. See our protein-rich meal prep ideas.
