Two-slot freezer planners
If space is tight, a plain white fish and salmon offer more distinct meal options than two similar coated fish products.
Who is this choice for?
Fish-meal planners
Keeping salmon alongside white fish makes it easier to plan a meal with oily fish. NHS guidance recommends two portions of fish a week, including one portion of oily fish.
Convenience-first households
Breaded or battered fish may suit a familiar oven-cooked meal. Compare the exact product’s fish species, cooking directions and allergens rather than assuming coated products are alike.
What matters when choosing?
Decide what each freezer slot needs to do, then compare the packs themselves: fish type, preparation, quantity and instructions can all change how useful a choice is.
Plain white fish
Choose it when: You want an uncoated fish to season and serve in different meals.
Trade-off: A plain fillet needs more preparation than a coated, oven-ready product; check for bones and follow its cooking directions.
Salmon portions
Choose them when: Your second slot is for oily fish; NHS guidance includes one oily-fish portion among two weekly fish portions.
Trade-off: Salmon’s richer flavour will not suit every recipe that calls for a mild white fish.
Coated fish
Choose it when: An oven-cooked meal with less preparation matters more than an uncoated ingredient.
Trade-off: The coating makes it less flexible for other recipes, and ingredients and cooking directions differ by product.
| Priority | What to check | Your needs |
|---|---|---|
| Fish variety | Compare species and whether each fish is plain or coated. Check pack weight and portion format rather than assuming two packs cover the same number of meals. | I have room for two choices and want them to work for different meals, not duplicate the same coated-fish option. |
| Preparation | Read the cooking method and directions on each pack. Check whether it calls for cooking from frozen or thawing first. | For a straightforward oven meal, I may prefer coated fish; for seasoning and sauces, I want a plain ingredient. |
| Sourcing | Look for named origin or traceability details on the exact product. If independent confirmation matters, check the pack for an independent label rather than relying on a brand claim alone. | I want clear sourcing information. In the Marine Stewardship Council and GlobeScan’s 2022 survey of 1,000 UK self-identified seafood consumers, 77% said supermarket or brand sustainability and environmental claims need clear labelling by an independent organisation. |
| Storage and allergens | Follow the pack’s frozen-storage, thawing and cooking instructions. Read its current allergen declaration, particularly for coated or marinated fish. | I need to know how to store and prepare the fish I choose, and which ingredients are in that specific pack. |
What should you avoid?
-
Filling both slots with similar coated fish
Two breaded or battered white-fish products may serve much the same kind of meal and leave no oily-fish option in the freezer.
If variety is the aim, consider plain cod or hake alongside salmon. Give a slot to coated fish when easier preparation is the stronger priority.
-
Treating every frozen fish product alike
Species, coatings, ingredients and cooking methods differ, so one product may not work in a recipe intended for another.
Compare the fish species, pack size, preparation and allergens on the exact products you are considering.
-
Reusing another pack’s thawing instructions
Marks & Spencer directs buyers of its Wild Icelandic Cod Fillets to store them at -18°C, defrost in a refrigerator, use within 24 hours of defrosting and not refreeze after thawing. Those are instructions for that product, not every frozen fish.
Keep each product frozen as directed and follow its own thawing and cooking instructions.
Brand ranges to consider
M&S Food
Its frozen range includes named plain fish options such as Wild Icelandic Cod Fillets and British Hake Fillets, as well as Scottish Salmon Portions.
- M&S describes fish in its frozen range as responsibly sourced and traceable; check the specific pack for the information that matters to you.
- The cod product has particular thawing and cooking requirements, including a warning that it may contain bones.
Young's
Young's lists natural Atlantic cod and Pacific pink salmon fillets alongside other frozen fish formats.
- The brand says its natural fish fillets can be cooked from frozen; follow the instructions on the chosen pack.
- A natural fillet and a coated product serve different preparation needs, even when both contain the same fish species.
Birds Eye
Birds Eye’s frozen range includes coated cod, haddock and Alaska pollock products, as well as fish fingers.
- Its coated formats give shoppers an option when they want to cook a familiar fish meal from frozen.
- Fish fingers or coated fillets are not interchangeable with plain fillets for recipes that call for uncoated fish.

Questions about choosing and storing fish
Which two frozen fish should I choose for limited freezer space?
Consider a plain cod or hake option alongside salmon if you want a flexible white fish and an oily fish for different meals. If a straightforward coated-fish meal is more useful to you, give it one slot instead of buying a second similar plain or coated product.
Does frozen salmon fit NHS fish guidance?
Salmon is an oily-fish option. NHS guidance recommends at least two portions of fish a week, including one of oily fish; check the pack’s quantity against the portions you intend to serve rather than assuming every pack contains two portions.
Can coated fish take the place of a plain fillet?
Yes, if a familiar meal with less preparation is the priority. Choose a plain fillet when you want to add your own seasoning or use the fish in different recipes, and read the coated product’s ingredients, allergens and cooking directions.
How should I thaw frozen fish?
Follow the instructions for the exact product. Marks & Spencer says its Wild Icelandic Cod Fillets should be defrosted in a refrigerator, used within 24 hours and not refrozen after thawing; the product is raw and must be cooked.
What allergen information should I check?
Read the current pack’s allergen declaration for the fish and any coating or marinade ingredients. Do not assume that two products containing the same fish species have the same ingredients.
