Plain frozen chicken breast is a useful starting point when you want to compare declared protein and energy per 100g; the Waitrose example contains chicken breast fillet as its sole ingredient. Coated chicken is a different meal format: check its chicken percentage, other ingredients and cooking directions rather than treating pack weight as equivalent to plain fillets.
If protein and energy both matter to your meal plan, compare the figures per 100g on the exact pack. Plain breast fillets offer a straightforward starting point: Waitrose declares 22.9g protein and 107kcal per 100g for its frozen breast fillets.
A larger pack may suit meals you plan to portion yourself. Check its net weight and preparation instructions, then compare its declared protein per 100g with any smaller pack you are considering.
If cooking from frozen matters more than starting with plain chicken, check the directions for the specific product. Birds Eye says its Buttermilk Chicken Strips cook from frozen in 25 minutes; their ingredients also include wheat and milk.
Start with the nutrition declaration and ingredients, then check whether the pack size and cooking directions fit the meals you intend to make.
| Priority | What to check | Your needs |
|---|---|---|
| Protein and energy | Compare protein and energy per 100g on the exact products. Check whether each is plain chicken or includes a coating or sauce. | I want to see how much protein a portion contributes while considering its energy value. Waitrose declares 22.9g protein and 107kcal per 100g for its plain frozen breast fillets. |
| Ingredients | Read the chicken percentage and ingredient list, particularly for coated products. Check the allergen declaration on the current pack. | If I choose coated chicken, I need to know what else is in it. Birds Eye lists chicken breast as 56% of its Buttermilk Chicken Strips and includes wheat and milk. |
| Pack format | Check net weight and whether the chicken comes as fillets, slices, strips or prepared pieces. Use the per-100g declaration when comparing different pack sizes. | A larger pack could work for meals I portion myself; smaller pieces may suit a different recipe. Pack size alone does not tell me the protein content of a serving. |
| Preparation | Check whether the pack says to defrost before cooking or provides cook-from-frozen directions. Follow its storage and cooking instructions. | I need the preparation method to fit the time available. Waitrose says to defrost its plain breast fillets fully before use, whereas Birds Eye gives cook-from-frozen directions for its Buttermilk Chicken Strips. |
| Origin and handling | Read the country-of-origin statement if it matters to you. Keep raw poultry separate from ready-to-eat food and follow the pack directions for thorough cooking. | When origin affects my choice, I can check the exact pack rather than assume it from the brand. I also need to prepare raw chicken safely: the Food Standards Agency says freezing alone cannot make it completely safe. |
A description of the meat used does not describe every ingredient in the finished product. Birds Eye lists chicken breast as 56% of its Buttermilk Chicken Strips; the product also contains coating ingredients.
Check the chicken percentage, protein and energy per 100g, and allergen declaration before comparing coated chicken with plain fillets.
The Food Standards Agency says freezing cannot make chicken completely safe on its own. Its review identifies cooking throughout to 70°C or more as an effective control against Campylobacter.
Follow the exact pack’s defrosting and cooking directions, and keep raw poultry and its utensils separate from ready-to-eat food.
Waitrose describes its frozen breast fillets as British and makes slower-reared and more-space welfare claims. Those attributes do not establish a difference in protein or energy content.
Check origin or welfare information separately from the product’s nutrition declaration, according to which details matter to your choice.
These examples illustrate differences between plain fillets and coated chicken; a retailer’s range or claim does not describe every product it sells.

Waitrose Frozen Chicken Breast Fillets 1kg provide a documented plain-fillet example: Waitrose lists chicken breast fillet as the ingredient and declares 22.9g protein and 107kcal per 100g.

Keep raw poultry separate from ready-to-eat food and follow its pack instructions for defrosting and thorough cooking. The Food Standards Agency says freezing alone cannot make chicken completely safe; its review says heating chicken throughout to 70°C or more reduces Campylobacter within minutes.
Yes. UK government food-labelling guidance says poultry sold to consumers must show its country or place of origin. Check the exact pack for that statement rather than assuming origin from the retailer or brand.
Some do: Birds Eye lists wheat and milk ingredients in its Buttermilk Chicken Strips and says the product may also contain celery, egg, mustard and soya. Check the current label of whichever product you choose, as ingredients differ between products.
