If you train, a fridge full of ready-made protein-rich lunches and dinners makes the week easier. This guide gives you ten meal prep ideas built from everyday UK ingredients like chicken, turkey mince, eggs, tinned fish, beans, lentils, yoghurt and tofu, with notes on which keep in the fridge and which are better frozen.

What makes a meal protein-rich
The NHS Eatwell Guide groups “beans, pulses, fish, eggs, meat and other proteins” as one of the main food groups. It suggests eating more beans and pulses, at least 2 portions of fish a week (1 of them oily), and less red and processed meat. For meal prep, the simplest approach is to build each box around one protein food, then add a starchy carb and plenty of veg.
We call these meals protein-rich because each one is built around a protein food. We don’t give gram targets or nutrition figures. Those depend on the exact recipe and portion, and we only publish them once they have been properly calculated for a tested recipe. If you want a personal protein target, a registered dietitian can help.
Protein foods that batch cook well
- Chicken thighs or breast: roast, poach or shred. Thighs stay juicier when reheated.
- Turkey mince: chilli, meatballs, ragù and stuffed peppers.
- Eggs: boiled, or baked into frittatas and egg muffins.
- Tinned fish: tuna, salmon, sardines and mackerel. They need no cooking and are good for lunches.
- Beans and lentils: tinned beans are ready to use, and red lentils cook down in about the time it takes to make a sauce.
- Greek-style yoghurt or skyr: for overnight oats, breakfast pots and quick sauces.
- Tofu: press, cube and bake a tray at a time.
For timing these around your sessions, see meal prep for training days.
10 protein-rich meal prep ideas
These are ingredient combinations, not full recipes, so scale them to suit you. Each box follows the same pattern: one protein food, one starchy carb and veg.
- Lemon-herb chicken traybake: chicken thighs, peppers, red onion and new potatoes roasted on one tray. Box with a handful of spinach. Fridge for two days; the rest freezes well.
- Turkey chilli: turkey mince with tinned kidney beans, tomatoes, onion and spices. Serve with rice or a jacket potato. Freezes well in single portions.
- Red lentil and chickpea dahl: red lentils and tinned chickpeas cooked with onion, garlic, ginger and spices, plus spinach stirred in at the end. Freezes well.
- Baked salmon, rice and greens: salmon fillets baked alongside broccoli or green beans, with rice. Eat within two days, and see the rice rules below.
- Tuna and sweetcorn pasta salad: wholewheat pasta, tinned tuna, sweetcorn, cucumber and a Greek-yoghurt dressing. A cold lunch; keep it chilled.
- Veg-loaded egg muffins: beaten eggs with peppers, spring onion, spinach and a little cheese, baked in a muffin tin. Pair with wholegrain toast or a wrap. Fridge for two days.
- Chicken and black bean burrito bowls: shredded chicken, tinned black beans, rice, sweetcorn and salsa. Add the yoghurt or avocado on the day. Fridge for two days.
- Baked tofu noodle boxes: pressed, cubed tofu baked with soy and garlic, then boxed with noodles, shredded cabbage, carrot and edamame. Fridge for two days.
- Turkey meatballs in tomato sauce: turkey mince meatballs baked and finished in a tomato and veg sauce, served with pasta or potatoes. Freezes well.
- Overnight oats with yoghurt: oats, Greek-style yoghurt or skyr, milk and berries in jars for grab-and-go breakfasts. Make two or three at a time.
Rotating proteins through the week, say chicken, fish, beans and eggs, keeps things interesting and fits the Eatwell advice on fish, pulses and red meat. Our recipes section will add fully tested versions of dishes like these.
Storing and reheating
Food safety matters more with meal prep, because food sits in the fridge for longer. The Food Standards Agency (FSA) advises:
- cool cooked food and get it into the fridge or freezer within one to two hours, and split big batches into smaller containers so they cool faster
- keep your fridge between 0 and 5°C
- eat leftovers within 48 hours, or freeze them
- rice: cool it quickly (ideally within an hour), keep it in the fridge for no more than a day, and never reheat it more than once
- reheat food only once, until it’s steaming hot all the way through
- defrost frozen portions in the fridge, not on the worktop
In practice, that means cooking for two days in the fridge and freezing the rest in labelled single portions. Our guide on how long meal prep lasts in the fridge and freezer has a full week plan built around this.
Building a week around training days
Cook two proteins on your prep day, such as a tray of chicken and a pot of dahl, and you can mix them into different boxes all week. On days you train in the evening, make sure dinner is already in the fridge so you only need to reheat it. See meal prep for training days for morning, lunchtime and evening session plans. If you’re new to this, start with meal prep for beginners.
Halal options
Every idea above works with halal-certified chicken or turkey, or with fish, eggs, beans, lentils and tofu. Check the labels on stock cubes, sauces and pastes too. Our halal meal prep page has more.
Frequently asked questions
What are good protein foods for meal prep?
Chicken, turkey mince, eggs, tinned fish, beans, lentils, chickpeas, Greek-style yoghurt and tofu all batch cook or store well. Mixing animal and plant proteins through the week gives you more variety.
How long does chicken meal prep last in the fridge?
The FSA advises eating cooked leftovers within 48 hours, or freezing them. If chicken is boxed with rice, follow the stricter rice rule and eat it within a day. Our storage guide covers this in more detail.
Can I freeze egg-based meal prep?
The FSA says eggs can be frozen: crack them into a sealed container, or beat them first, ready for scrambled eggs or an omelette later. Treat cooked egg dishes like any other leftovers. Cool them quickly, freeze in portions, defrost in the fridge and reheat once until steaming hot. The texture of cooked eggs can change after freezing, so try a small batch first.
Is this “high protein” meal prep?
We describe these meals as protein-rich because each is built around a protein food. We’d only call a specific dish “high protein” once its nutrition had been calculated.
