New parents with little preparation time
A fish product with a suitable cook-from-frozen method can help when there is no time to thaw dinner. Check the method and timing on the individual pack: they differ between fillets.
Who is this for?
Breastfeeding parents planning fish meals
White fish and oily fish have different roles in the NHS fish guidance. The NHS advises at least two fish portions a week, including one oily portion, and no more than two oily-fish portions a week for women, including those breastfeeding.
Households considering coated fish
Breaded or battered fillets offer a different meal format from plain fish. Check the exact ingredients, allergen warnings, cooking directions and advice about possible bones, particularly if children will share the meal.
What should you check?
Plain white-fish fillets
Choose when: You want an uncoated fish base to serve with different sides.
Allow for: The cooking method varies by product; some fillets need thawing first.
Oily-fish portions
Choose when: You are planning a meal with oily fish such as salmon, rather than white fish.
Allow for: NHS oily-fish portion guidance may be relevant during pregnancy or breastfeeding, and preparation differs by pack.
Breaded or battered fillets
Choose when: A coated fish format fits the dinner you are making.
Allow for: Coatings change the ingredients and nutrition values; check allergens on the exact product.
| Priority | What to check | Your needs |
|---|---|---|
| Cooking | Check whether the pack directs you to cook from frozen or thaw first. Match its oven, microwave or air-fryer directions to your equipment and available time. | I need a dinner I can prepare with the equipment and time available that day. |
| Fish type | Identify the species, not just a front-of-pack claim. The NHS identifies salmon as oily fish and cod and haddock as white fish; its oily-fish guidance is relevant during pregnancy and breastfeeding. | If I am planning an oily-fish meal, I want to know that the portion is oily fish rather than white fish. |
| Coating and labels | For coated products, read the ingredients and allergen declaration. Compare energy, fat and salt per 100g or per serving on the products you are considering. | A coated fillet may suit tonight’s meal, but I need its ingredients and nutrition panel to work for my household. |
| Bones and storage | Read any residual-bone warning and the instructions for frozen storage, defrosting and refreezing. Check cooked fish carefully before serving it to children. | I want clear handling directions and will not assume that the word “fillet” rules out bones. |
| Pack size | Check the stated net weight, fillet count and any portion information; pack formats differ. | I need enough portions for the people eating, without assuming every pack contains the same number of fillets. |
Common buying mistakes
Assuming every fish portion has the same nutritional role
The NHS distinguishes oily fish, including salmon, from white fish such as cod; white fish contains less long-chain omega-3.
Check the species when choosing fish for a particular meal, and follow the relevant NHS oily-fish guidance if you are pregnant or breastfeeding.
Treating coated fish as identical to plain fish
Breadcrumbs or batter change the ingredient list. For example, Birds Eye breaded cod lists wheat and mustard, while nutrition values are specific to each product.
Read the allergen declaration and compare nutrition per 100g or per serving on the packs you might buy.
Assuming a fillet cannot contain bones
Birds Eye breaded cod and M&S breaded haddock both warn that bones may remain.
Check the warning on your pack, then inspect and flake cooked fish carefully, especially before serving it to children.
Using another product’s cooking directions
Tesco cod has microwave-from-frozen directions, whereas the cited Birds Eye breaded cod has oven and air-fryer directions. Those methods are not interchangeable instructions for every fillet.
Follow the storage, thawing and cooking directions on the product in your freezer.

Frequently asked questions
Can frozen fish fit into meals while breastfeeding?
Yes, provided you choose the fish type deliberately as part of your meals. The NHS advises breastfeeding parents to aim for at least two portions of fish a week, including one oily portion, while women, including those breastfeeding, should have no more than two oily-fish portions a week. White fish does not count as an oily-fish portion.
Which fish guidance matters during pregnancy?
The NHS advises avoiding shark, swordfish and marlin during pregnancy and having no more than two portions of oily fish a week, including salmon, trout, mackerel and herring. Identify the fish species on the pack rather than relying on a general claim on the front.
Should I buy plain or coated fillets?
Choose plain fillets when you want an uncoated base for different meals; choose coated fish when that format suits your dinner. Ingredients and nutrition differ by product: Tesco’s cited plain cod lists 91 kcal and 0.25g salt per 100g, while the cited M&S breaded haddock lists 189 kcal and 0.53g salt per 100g. Those figures describe those two products, not every plain or coated fillet.
Does “boneless” mean I can skip checking cooked fish?
No. Some fillet products warn that bones may remain. Read the current pack and inspect and flake cooked fish carefully, particularly before serving it to children; also check ingredients and allergen warnings for everyone eating it.
Can every frozen fillet go straight into the oven?
No. Cooking and thawing directions are product-specific: the cited Tesco cod has an oven-from-frozen route, while some other fillets direct you to thaw before cooking. Follow the storage, defrosting and cooking instructions on the exact pack.
