Cooking for one
A prepared fish pie gives you a single main dish, while a two-fillet pack lets you consider whether one piece suits your plate. Compare the pack weight and stated servings before deciding what to cook.
Who is each format for?
Cooking for one or two with mash on the side
Coated fillets provide a ready-made batter or breadcrumb layer. Plain fillets leave you to choose the seasoning or sauce; either way, check how many pieces you intend to use.
Checking ingredients closely
Choose the exact product by its current ingredient and allergen declaration, not by the words “fish fillets” alone. Coated products contain ingredients beyond the fish, and declarations differ between packs.
What should you check before choosing?
Decide whether mash is a side dish or already part of the main, then check the portion, ingredients and preparation instructions on the particular pack.
| Priority | What to check | Your needs |
|---|---|---|
| Meal format | Check whether a prepared fish pie already has a potato topping. For fillets, compare the piece count, pack weight and stated servings; a larger bag is more useful for one meal if you can take out the pieces you need while the rest stays frozen. | Am I planning mash as a side, or would a potato-topped fish pie be the whole main dish? If I am cooking alone, how much of this pack would I use? |
| Coating and allergens | Read the ingredients and allergen declaration for the exact pack. Decide whether you want a prepared coating or plain fish that you can season and sauce yourself. | I would like fish with a ready-made coating, but I need to check what else that coating contains. Alternatively, I can choose plain fish and prepare the accompaniments separately. |
| Cooking and storage | Check whether the selected product is cooked from frozen or thawed first, which appliance its directions cover, and what the pack says about storage after defrosting. Instructions for one product do not apply to another. | Will the fish fit the way I am cooking the rest of dinner? I also want to know what to do with any pieces left in the pack. |
| Fish type | Check the named fish species and whether the product is plain, coated or part of a prepared meal. If choosing salmon instead of white fish, account for the different type of fish in the meal you have planned. | Would I rather serve white fish with my own sauce, or use a different fish such as salmon? The fish type matters separately from the number of portions. |
Common mistakes to avoid
-
Treating fish pie as just the fish beside mash
A prepared fish pie already includes a potato topping, so a separate serving of mash adds another potato component to the plate.
If mash is the side dish you want, consider fillets instead. If you choose fish pie, decide whether you want any extra mash at all.
-
Assuming two fillets are two stated servings
The piece count describes what is in the pack; it does not establish the manufacturer’s serving size or how much you want for one meal.
Compare the serving guidance with the total weight and number of pieces before planning plates or leftovers.
-
Assuming coated fish has the same ingredients as plain fish
Batter and breadcrumbs add ingredients. For example, the supplied description of Young’s Chip Shop 4 Cod Fillets declares fish, wheat and mustard allergens.
Read the current declaration on the specific pack, particularly when avoiding an ingredient; do not transfer one product’s declaration to another.

Questions about portions and preparation
Should I serve frozen fish pie with mash?
You can, but fish pie already has a potato topping. If you want mash as a separate side, a fillet may suit that plan more directly; otherwise decide whether the pie needs any extra mash.
Does “2 fillets” mean two single servings?
No. It tells you the piece count, not the stated serving size. Check the manufacturer’s serving guidance and the pack weight before deciding how many fillets to cook.
Can I cook coated fish straight from frozen?
Some coated products have cook-from-frozen directions. Birds Eye’s instructions for its 2 Fish Fillets in Breadcrumbs give 20 minutes for oven cooking or 14–16 minutes for air-fryer cooking; follow the directions on the product you actually choose.
What should I check on a breaded fish label?
Check the fish species, full ingredients, allergen declaration, stated servings and cooking directions on the current pack. Coatings differ: the supplied description of Young’s Chip Shop 4 Cod Fillets, for example, declares fish, wheat and mustard allergens.
Can I refreeze fish after it has thawed?
Follow the selected pack’s instructions rather than assuming the same rule applies to every product. Birds Eye says not to refreeze its breadcrumb fillets after defrosting; M&S says its Scottish Salmon Portions should be eaten on the day of defrosting and not refrozen.
