Homemade fish-pie cooks
Plain fillets let you prepare the fish with your own sauce and mash. Check the named species and usable pack weight so you can plan how much fish goes into the pie.
Who is this for?
Households serving fish beside mash
Breaded or battered portions fit a plated meal rather than a pie filling. Check the pack’s cooking method and ingredients before choosing a coated product.
Ingredient- and allergen-aware shoppers
Check the exact pack for fish species, coating ingredients, allergens and bone warnings. GOV.UK guidance says regulated allergens present as ingredients in UK prepacked food must be clearly identified in the ingredients list.
What matters when choosing?
Decide whether the fish will go into a pie or be served beside mash, then compare the details that matter within that format.
| Priority | What to check | Your needs |
|---|---|---|
| Meal format | Check whether the pack contains plain fillets or coated portions, and follow its stated preparation method. Coated portions are not a direct substitute for uncoated pie fish. | For a homemade pie, I want fish to prepare with sauce. If fish will sit beside the mash, a breaded or battered portion may fit instead. |
| Species and fish content | Read the named species in the ingredients. For coated fish, check the fish percentage: Tesco Groceries lists cod as 52% of its examined breaded cod product, while Birds Eye lists Alaska pollock as 51% of its examined breaded fillets. | I want to know which fish I am serving and, with a coated portion, how much of the product is fish rather than coating. |
| Usable quantity | Check the net weight, portion count and any distinction between fish weight and ice or coating. Do not treat the whole weight of a coated pack as plain fish. | There needs to be enough fish for the number of diners, whether I am making one pie or serving individual portions. |
| Pack instructions | Check allergens, bone warnings, cooking equipment, frozen storage and any defrosting instructions on the exact pack. GOV.UK says regulated allergens present as ingredients must be identified in the ingredients list of UK prepacked food. | I need a product I can prepare with the equipment available and serve with attention to the pack’s allergen and bone information. |
What should you watch for?
-
Assuming every pack contains the same proportion of fish
A coated pack includes more than fish. Tesco Groceries lists cod as 52% of its examined breaded cod fillets, so its full pack weight does not represent the weight of cod alone.
Compare plain fillets with plain fillets for a pie. When considering coated portions, read the fish percentage as well as the pack weight.
-
Assuming a coating has no additional allergens
The examined Tesco breaded cod includes wheat and milk proteins; Birds Eye lists wheat and mustard in its examined breaded fish fillets and says they may contain milk.
Read the ingredients and allergen information on the exact pack you intend to use, even if you have bought the brand before.
-
Overlooking cooking, storage and bone warnings
Instructions vary by product. For example, the examined ASDA white-fish fillets specify what to do after defrosting, and Birds Eye warns that bones may remain in its examined breaded fillets.
Choose a pack whose cooking instructions you can follow, observe its storage and defrosting directions, and check for bones when serving.

Ocean Classic Pangasius Fillet Skinless & Boneless IQF 170/200g, 1kg
These plain pangasius fillets fit a homemade pie where you prepare the fish and sauce yourself. The listing describes the fillets as skinless and boneless and gives thawing and cooking directions. Check the pack’s usable fish weight before planning portions: the description gives conflicting explanations of the stated 800g figure. Check its bone information before serving.

Ocean Classic Tilapia IQF Fillets, 800g Net, 1kg
These plain tilapia fillets are an option for fish prepared as part of a homemade pie. The listing identifies tilapia and states an 800g net quantity, with thawing and cooking guidance. Check the exact pack for skin and bone information before preparing and serving it.

Young's Chip Shop 4 Cod Fillets 400g
These battered cod fillets suit fish served beside mash rather than fish folded into a pie. The listing gives oven-from-frozen instructions and identifies cod as 54% of the product, so the 400g pack is not 400g of plain cod. It lists fish, wheat/gluten and mustard allergens and warns that bones may remain; check the current pack before serving.
Common questions
How do I compare frozen fish packs for a homemade pie?
Start with plain fillets, then check the species and net fish quantity against the number of portions you need. A coated product is a different comparison because some of its pack weight is batter or breadcrumbs.
Should I use breaded or battered fish in a pie?
Plain fillets are the more direct choice for a homemade pie with your own sauce. Choose coated portions when the fish will be cooked and served beside mash, following the instructions on that product’s pack.
Can breaded fish contain allergens besides fish?
Yes. Tesco Groceries lists wheat and milk proteins in its examined breaded cod, while Birds Eye lists wheat and mustard in its examined breaded fillets and says they may contain milk. Check the exact current pack; GOV.UK says regulated allergens present as ingredients in UK prepacked food must be clearly identified in its ingredients list.
Can I refreeze fish after it has thawed?
Follow the instructions for the exact product. The examined ASDA white-fish fillets and M&S hake say to use the fish within 24 hours of refrigerator defrosting and not to refreeze it after thawing; the examined Tesco breaded cod also says not to refreeze it once thawed.
Does a boneless fillet mean there cannot be any bones?
No. Fish products described as boneless may still carry a warning that bones can remain. Read the pack and check the fish when serving, particularly to children.
