Quick-lunch planners
If tuna is going into a salad, wrap or jacket potato without cooking, a tinned format fits that routine. Check the packing medium and drained weight when working out how much fish goes into a portion.
Who each format suits
Cooked-steak meal planners
Frozen tuna steaks suit a meal built around a cooked fillet, provided you can store them frozen and follow the pack’s preparation instructions.
Nutrition-label comparers
If protein, salt, energy or added oil affects your choice, compare the exact variants on their stated serving and food-state bases. A drained-tin figure and a pan-fried-steak figure describe different states of the fish.
What to check before buying
Decide whether immediate use or a cooked steak matters more, then compare nutrition on the portion and preparation basis you will actually use.
| Concern | What to check | Who this matters to |
|---|---|---|
| Protein per portion | Check protein per serving and whether the figure refers to drained, raw or cooked fish. Use the edible portion, not just the pack weight. | If I plan meals around protein, I need to know what the portion I will eat contributes. About 40% of consumers put protein per usable portion first. |
| Preparation and storage | Check whether a tin needs draining and whether frozen steaks can be cooked from frozen or must be defrosted for your chosen method. | When lunch has to be ready without cooking, preparation time drives the choice; for dinner, I may be able to plan around a frozen steak. Immediate use is the primary need for about 30% of consumers. |
| Salt, energy and packing medium | Read the exact variant’s ingredients and nutrition label, particularly if it is packed in brine or oil. | If I am comparing meal ingredients by salt, energy or added oil, the packing medium matters alongside protein. About 20% of consumers make those label details their main concern. |
| Steak format and sourcing detail | Check whether the product is a whole steak or chunks, and read any species, catch-method or traceability statement for that item. | For a cooked main meal, I may want a whole fillet rather than tuna to mix into a dish; a product-specific sourcing statement may also shape my choice. Those preferences come first for about 10% of consumers. |
Buying pitfalls
-
Comparing protein figures for different food states
Princes Food & Drinks lists 23.5g protein per 100g drained for its Tuna Chunks in Spring Water, while ASDA Groceries lists 32g per 100g pan-fried for its frozen tuna steaks. Those figures do not describe the same preparation state.
Check the stated serving and whether each figure is for drained, raw or cooked fish before comparing meal portions.
-
Treating every tin as the same recipe
Water, brine and oil-packed variants can have different ingredients and nutrition values. A figure for one product should not be carried across to another.
Read the exact can or pot for its packing medium, salt, energy and drained weight.
-
Choosing frozen steaks for an immediate meal
Frozen steaks need preparation. Tesco Groceries gives different instructions for its tuna steaks: 20 minutes under a medium grill from frozen, or 6–8 minutes shallow-frying after defrosting.
Use the instructions for the product and cooking method you choose; keep ready-to-use tinned tuna in mind when cooking time is the deciding factor.
Cooking adds preparation time and, depending on the method, may involve cooking oil.
-
Planning frequent tuna meals without checking pregnancy guidance
For people who are pregnant or trying for a baby, the NHS advises no more than 4 cans of tuna or 2 tuna steaks a week.
If that guidance applies to you, account for tuna across the week when planning meals with either format.
Brands to consider
John West
A reference point for convenient tinned formats, including no-drain tuna pots.
- A Sainsbury’s listing describes a John West no-drain pot as ready to eat.
- Check the specific product: a pot’s format and nutrition details do not apply to every John West tin.
Princes
Offers tinned tuna in formats useful for comparing packing media and preparation steps.
- Princes Food & Drinks lists tuna and spring water as ingredients for its Tuna Chunks in Spring Water; its drained tuna range is described as ready to use.
- The spring-water product’s nutrition figures are product-specific and stated per 100g drained.
Tesco
Its tuna listings provide points to check for both tinned products and frozen steaks.
- Tesco Groceries gives separate from-frozen and defrosted cooking instructions for its tuna steaks.
- Tesco cautions that ingredients and nutrition information can change, so use the current pack label for a purchase decision.
Sainsbury’s
Has product listings for canned tuna and steak-format yellowfin tuna.
- Its yellowfin steak listing identifies that particular product as previously frozen and defrosted.
- Check the individual listing and pack rather than extending its handling or sourcing statements to the whole range.
Asda
A reference for comparing a frozen tuna-steak label with tinned-tuna labels.
- ASDA Groceries lists 32g protein and 0.21g salt per 100g pan-fried for its frozen 2 Tuna Steaks product.
- That cooked basis differs from a drained-tin basis; the finished meal also depends on how the steaks are prepared.
M&S
Provides product-specific descriptions for tinned tuna steak and frozen yellowfin steaks.
- M&S describes one tinned tuna steak as pole-and-line caught and its frozen yellowfin steaks as skinless and boneless.
- These descriptions identify particular products, not every tuna item in the range.

Questions about choosing tuna
Does frozen tuna contain more protein than tinned tuna?
Those formats cannot be ranked from unlike label bases. Princes Food & Drinks lists 23.5g protein per 100g drained for its spring-water tuna chunks, while ASDA Groceries lists 32g per 100g pan-fried for its frozen tuna steaks. Compare the portion you intend to eat and whether each figure refers to drained, raw or cooked fish.
Can I cook tuna steaks from frozen?
Follow the instructions on the steak pack for your cooking method. Tesco Groceries specifies grilling its tuna steaks from frozen for 20 minutes, but shallow-frying them for 6–8 minutes from defrosted; those timings should not be transferred to a different product.
How much tuna can I eat if I am pregnant or trying for a baby?
The NHS advises no more than 4 cans of tuna or 2 tuna steaks a week for people who are pregnant or trying for a baby. Count tuna meals across the week whether you choose tinned tuna or steaks.
