Cooked-dinner shoppers
A chilled or frozen steak suits a planned main course when there is time to store, thaw if required, and cook the fish according to its pack instructions.
Who is each format for?
Quick-lunch shoppers
Tinned steaks or fillets suit salads, jacket potatoes and other meals where cooking the tuna would add an unwanted step. Pack size and leftover instructions still matter.
Sourcing-focused shoppers
The named species, fishing-method statement and any certification on the particular pack offer more useful points of comparison than a premium label alone.
What matters when choosing?
Decide whether the meal needs cooked fish or tuna ready for a no-cook dish, then check the exact pack for storage, sourcing and nutrition details.
| Concern | What to check | Who this matters to |
|---|---|---|
| Meal format and preparation | Check whether the fish is raw, chilled, frozen or tinned, and follow any thawing and cooking directions. | For a plated dinner, I want a steak to cook rather than tuna straight from a tin. About 42% of consumers put that meal-format choice first. |
| Convenience and leftovers | Compare pack size, whether draining is needed, and the after-opening storage instructions. | When lunch needs to come together without cooking, I want usable portions and a plan for anything left over. No-cook convenience is the main concern for about 33% of consumers. |
| Sourcing and pack details | Look at species, sourcing statements and packing medium; compare nutrition per 100g on the exact labels. | If the sourcing or ingredients influence my choice, I need to read the particular pack rather than rely on the word premium. About 25% of consumers make those details their primary concern. |
Buying pitfalls
-
Assuming every tuna steak needs searing
“Tuna steak” can describe both tinned fish and raw fish. Marks & Spencer identifies its chilled yellowfin steaks as raw and says they must be cooked, while its tinned tuna steak is intended for use without that preparation.
Choose the meal format first, then check whether the product is tinned, chilled or frozen before following its preparation instructions.
-
Judging nutrition by the word “fillet” or “steak”
The cut name does not tell you what oil, water, brine or flavourings are in the pack. Nutrition figures also need to be compared on the same basis.
Read the ingredients and compare the per-100g figures on the exact products you are considering, including whether the figures refer to drained fish.
-
Opening a large tin without a leftover plan
Marks & Spencer instructs shoppers to move unused fish from its cited 800g tuna-steak tin to a non-metallic container, refrigerate it and eat it within two days.
Match the pack to the portions you need and follow its own after-opening directions.
A larger pack may leave fish unused if those storage directions do not fit your meal plans.
-
Assuming a change of format changes pregnancy guidance
The NHS advises people who are pregnant or trying for a baby to have no more than four cans of tuna or two tuna steaks a week because tuna can contain mercury. Choosing fresh tuna instead of tinned tuna does not remove that guidance.
Check the NHS guidance when planning meals if it applies to you.
Brands to consider
M&S
Its cited range includes tinned tuna steak in spring water and raw yellowfin steaks for cooking.
- The cited spring-water tuna is described by M&S as pole-and-line caught; check the claim on the pack you choose.
- The cited raw yellowfin product must be cooked, so it is not interchangeable with the tinned option for a no-cook meal.
Tesco
Tesco lists both tinned tuna and Tesco Finest yellowfin steaks, offering different formats for lunch and a cooked dinner.
- Tesco identifies its cited 240g Finest yellowfin-steak pack as defrosted fish and provides cooking instructions.
- The defrosted steaks require cold storage and cooking; check the pack directions before planning the meal.
Princes
Princes offers plain tinned tuna alongside flavoured Ocean Select yellowfin steak products.
- Its cited lemon variety lists yellowfin tuna, olive oil, salt and natural lemon flavouring, making the packing ingredients part of the flavour choice.
- Ingredients and nutrition differ between varieties; Princes’ traceability statements should be checked against the exact pack.
John West
Tesco lists John West No Drain Fridge Pot Tuna Steak varieties in its tinned-tuna range.
- The cited range includes spring-water and sunflower-oil varieties in a no-drain format.
- Choose by the particular pot’s ingredients, nutrition and storage directions rather than assuming both varieties are alike.

Super Frozen Tuna Steaks, 2 Steaks, 260g
For a cooked steak-format dinner rather than a tinned-tuna lunch. Allow for frozen storage and follow the pack’s thawing, cooking and chilled-use instructions. Do not treat “sashimi grade” wording as confirmation that the fish is suitable to eat raw.

Fish4ever Tuna Steaks in Organic Olive Oil, 160g
Consider this olive-oil-packed tin for a meal where the packing medium matters. If intact steak pieces are important for plating, check the pack: the product information also describes the contents as chunks.

Morrisons Tuna Steaks in Sunflower Oil, 110g
A smaller sunflower-oil-packed option to consider for a tuna meal. Check the actual pack if draining affects your preparation: its title and description use conflicting drained and no-drain wording.
Common questions
Should I buy tinned tuna or a tuna steak for dinner?
Choose a chilled or frozen steak when you want to cook fish as the centre of the plate and can follow its storage and preparation directions. Choose tinned tuna steak or fillets when you want pieces of tuna for a salad, jacket potato or other meal without cooking the fish.
What should I do with tuna left in an opened tin?
Follow that tin’s instructions. Marks & Spencer directs shoppers to transfer unused fish from its cited tuna-steak products to a non-metallic container, refrigerate it and eat it within two days; instructions on another pack may differ.
Does pregnancy guidance differ for tinned and fresh tuna?
The NHS guidance covers both formats: it advises people who are pregnant or trying for a baby to have no more than four cans of tuna or two tuna steaks a week because tuna can contain mercury. Check the NHS guidance if it applies to your meal planning.
How can I compare sourcing claims on tuna?
Check the named species and any origin, fishing-method, traceability or certification information on each product. A claim on one brand’s tuna does not establish the sourcing of another variety, so compare the exact packs rather than relying on the word premium.
