A side-by-side look at protein, calories, cost and practicality for a typical serving of each.
| Metric | Chicken breast (150g raw) | Eggs (2 large) |

| Protein per serving | 33.8g | 14.6g |
| Calories per serving | 180 kcal | 166 kcal |
| Cost per serving | 68p-£1.05 | 58-75p |
| Cost per 25g protein | 50-78p | 99p-£1.29 |
| Prep needed | Cooking required, 15-25 minutes | Boil, fry or scramble in under 10 minutes |

| Meal-prep suitability | Batch cooks and reheats well | Best cooked fresh or as pre-boiled eggs |
Why The Answer Changes Depending On What You Mean By "Value"
If by value you mean cost per gram of protein, chicken breast wins clearly. If convenience matters more, eggs win, since they need less planning, no defrosting, and keep for weeks unopened. If batch cooking for the week is your priority, chicken breast is the more practical choice, since a single cooking session produces several portions that reheat well, while eggs are generally better cooked fresh each time.
Best Choice Depending On Your Goal
Which one to prioritise depends on what you are actually short on: money, time or planning.
- Lowest cost per gram of protein: chicken breast.
- Least planning and prep: eggs.
- Best for a Sunday batch-cook session: chicken breast.
- Best emergency backup protein with no meal prep: eggs, since they keep for weeks.
- Best combined approach: use chicken breast as your main batch-cooked protein and eggs to fill gaps at breakfast or when you have not prepped.
Frequently Asked Questions
Is chicken or eggs better for muscle gain?
Both provide high-quality complete protein. Chicken breast delivers more protein per serving and per gram of protein cost, so it is usually the more efficient choice for hitting a daily protein target, while eggs are a convenient addition rather than a replacement.
Are eggs cheaper than chicken?
Per serving, yes, eggs are usually cheaper. Per gram of protein, chicken breast is usually the better value, because eggs contain less protein relative to their weight.
Can I meal prep eggs for the week?
Hard-boiled eggs meal prep reasonably well and keep for about a week refrigerated in their shells. Scrambled or fried eggs are best cooked fresh rather than reheated.
