The biggest barrier to eating high-protein food consistently isn't knowledge — it's convenience. When there's nothing ready in the fridge at 7pm, the default is whatever is fastest, not whatever is best. Meal prep solves this with a single 2-hour investment on Sunday that pays off across the entire week.
This guide gives you an exact schedule, the right recipes to choose, and everything you need to store and reheat without losing quality.
The Core Principle: Cook Building Blocks, Not Full Meals
The biggest mistake in meal prep is trying to cook complete, identical meals for the entire week. By day 3, you're bored and by day 5 you're ordering takeaway. Instead, cook protein building blocks and versatile bases that can be assembled differently each day.
| Component | Used in | Prep time |
|---|---|---|
| Batch-grilled chicken breast (6 pieces) | Salads, wraps, bowls, pasta | 25 min |
| Cooked rice or quinoa (large pot) | Bowls, stir-fry, sides | 20 min |
| Roasted vegetables (2 trays) | Sides, bowls, omelettes | 30 min |
| Hard-boiled eggs (8–10) | Snacks, salads, breakfast | 15 min |
| Marinated salmon fillets (4–5) | Dinner, lunch bowls | 5 min prep + 15 min cook |
| Cooked lentils or chickpeas | Salads, sides, wraps | 25 min |
The 2-Hour Sunday Schedule
The key to doing this in 2 hours is running everything in parallel — oven, hob, and zero downtime.
Hour 1: Set everything in motion (0:00 – 1:00)
| Time | Action |
|---|---|
| 0:00 | Preheat oven to 200°C. Put pot of water on to boil for eggs. |
| 0:05 | Season 6 chicken breasts. Place on a foil-lined baking tray with olive oil. |
| 0:08 | Chop 2 trays of vegetables (peppers, courgette, cherry tomatoes, red onion). Season and add to second oven tray. |
| 0:15 | Both trays go into the oven (chicken 25–30 min, veg 25 min). Put eggs in boiling water (12 min for hard-boiled). |
| 0:16 | Start cooking rice or quinoa on the hob (follow packet, usually 18–20 min). |
| 0:28 | Remove eggs, transfer to ice water to cool. Check rice. |
| 0:35 | Remove vegetables from oven. Check chicken (internal temp 74°C). |
| 0:40 | Remove chicken. Let it rest for 10 minutes before slicing. Start marinating salmon (soy, garlic, honey — 5 min prep). |
| 0:50 | Slice chicken, portion into containers. Portion rice. |
Hour 2: Cook salmon + finish (1:00 – 2:00)
| Time | Action |
|---|---|
| 1:00 | Bake marinated salmon fillets at 200°C for 12–15 minutes. |
| 1:05 | Boil or drain lentils / chickpeas. Season and cool. |
| 1:20 | Remove salmon. Cool for 10 minutes before portioning. |
| 1:30 | Label all containers with contents and date. |
| 1:45 | Store in fridge. Done. |
Storage: How Long Does Each Component Last?
| Food | Fridge | Freezer |
|---|---|---|
| Cooked chicken breast | 3–4 days | 3 months |
| Cooked salmon | 2–3 days | 2 months |
| Cooked rice / quinoa | 4–5 days | 1 month |
| Roasted vegetables | 4–5 days | 2 months |
| Hard-boiled eggs (unpeeled) | 1 week | Not recommended |
| Cooked lentils / chickpeas | 4–5 days | 3 months |
💡 Label with the date, not just the content
Write the date you cooked it, not just what it is. "Chicken — Sun" is much more useful than just "chicken" when you're checking if it's still good on Thursday.
Reheating Without Ruining the Texture
- Chicken: Add a splash of water or broth to the container, reheat in microwave at 70% power in 60-second bursts, or warm in a pan over low heat. Never blast on full power — it turns dry.
- Salmon: Best eaten cold or at room temperature in a bowl/salad. If reheating, use a covered pan over very low heat with a splash of water.
- Rice: Add 1 tbsp of water per cup of rice, cover, and microwave for 90 seconds. Stir halfway.
- Roasted vegetables: Reheat in a hot oven (200°C) for 8–10 minutes to restore crispness. Microwaving makes them soggy.
- Lentils/chickpeas: Reheat in a pan with a little olive oil, or eat cold in salads.
Protein Totals for the Week
With this batch cook, you have roughly:
- 6 chicken breasts × ~45g protein each = 270g protein across the week
- 4–5 salmon fillets × ~40g protein each = 160–200g protein
- 10 eggs × 6g each = 60g protein
- Lentils/chickpeas: ~45g protein (across 5 servings)
- Total protein available: ~535–575g across the week
The Best Recipes to Use for Batch Cooking
These recipes are specifically designed to reheat well and work as meal prep building blocks:
- Honey Garlic Chicken Thighs — stays moist when reheated, works in any bowl
- Teriyaki Salmon Bowl — pre-marinated, bakes in 15 min
- Turkey Chili — the ultimate batch-cook protein meal, freezes perfectly
- Lemon Herb Baked Cod — 25 min, 32g protein, great cold the next day
