Choose a tinned tuna steak or named fillet if you want discernible pieces for a salad, pasta or jacket potato; choose fresh or frozen tuna instead if you want raw fish to cook. For one or two people, match the pack size to the meal, then check whether it needs draining, which liquid it contains and how the label says to store leftovers.
If you cook for one or two, a steak or fillet-style tin may suit salads, pasta or jacket potatoes when you want discernible pieces rather than loose sandwich tuna. Tesco lists a ready-to-eat tuna steak, while retailers also distinguish steaks from other tinned formats.
A smaller portion or no-drain format is worth considering when you want to open only what the meal calls for. John West describes its 3 x 60g spring-water steak pack as ready to eat without draining.
If the packing liquid, nutrition values or sourcing claim influences your choice, compare the exact products rather than assuming tins from the same brand have identical labels.
For one- or two-person households seeking fillet-like pieces in tinned tuna, start with the cut and portion, then compare the liquid and product-specific label.
| Concern | What to check | Who this matters to |
|---|---|---|
| Piece size | Look for steak or fillet wording and check that the format suits your dish; tinned fish is not a raw fillet. | If I want tuna to remain visible in a salad or on a jacket potato, the cut comes before convenience. About 31% of consumers put discernible pieces first. |
| Portions and preparation | Compare the pack weight, individual portions, draining instructions and storage directions after opening. | When I am making one lunch, I would rather open a suitable portion than plan around a larger leftover tin. Avoiding extra handling is the primary need for about 25% of consumers. |
| Liquid and nutrition | Check whether the tuna is packed in water, brine or oil, and compare nutrition per 100g on the exact labels. | If the tuna is going into pasta, I may want the oil; for another dish, the label values may matter more. Roughly 25% of consumers put liquid and nutrition first. |
| Sourcing and labelling | Read the pack for species, ingredients, the fish-allergen declaration and any product-specific catch or certification claim. | I want to know what the particular tin says about its fish and sourcing, rather than rely on a brand-wide impression. For about 19% of consumers, that label assurance is the main concern. |
A tinned tuna steak is preserved, ready-to-eat fish. Its larger-piece format does not make it raw tuna for searing.
Decide whether the meal calls for cupboard-ready tuna or raw fish to cook before choosing a pack.
Marks & Spencer lists 0.6g fat per 100g for its spring-water tuna steak and 6.4g per 100g for its sunflower-oil steak. Those figures compare two specific products, not every water- and oil-packed tin.
Choose a liquid that suits the recipe and compare the current per-100g labels if nutrition values matter to you.
Unused tuna needs to be handled according to the particular pack's storage directions; a larger tin is less convenient if you have no plan for the remainder.
Match the portion to the meal and check the label for how to store and use any leftovers.
Certification and catch information belong to the product bearing the claim, not automatically to every tuna format from its brand.
Check the exact pack for the certification or sourcing statement you want.
Its no-drain spring-water tuna steaks include a 3 x 60g format for shoppers who prefer smaller portions with less preparation.
Its range includes tuna steaks as well as other tinned tuna formats; a 110g drained spring-water steak is one relevant option.
Its 110g spring-water tuna steak offers a single-tin format to compare with other cuts and packing liquids.
Its tinned range includes steaks, fillets and versions packed in spring water or oil.
These tuna steaks are packed in sunflower or olive oil. They are options to consider when an oil-packed, ready-to-eat tin suits the meal, rather than substitutes for raw fresh fillets.

Consider this sunflower-oil tuna when the recipe calls for a tinned steak format. Check the current pack for its portion and storage directions if you will not use it all at once.

The single 110g tin may fit a meal planned around a smaller portion of oil-packed tuna. The product title says drained, while its description says no-drain, so check the pack before relying on either preparation method.

This 160g olive-oil tin is an option for a meal where oil-packed tuna suits the dish. Its title says steaks but its description also refers to chunks; check the expected piece format if intact, fillet-like pieces are your priority.
No. Tinned steaks and fillets are preserved, ready-to-eat fish, whereas a raw fresh fillet is bought to cook. Choose by the meal you intend to make, not the word steak alone.
Choose by the recipe and the exact nutrition label. Marks & Spencer lists 99 kcal and 0.6g fat per 100g for its spring-water tuna steak, compared with 159 kcal and 6.4g fat per 100g for its sunflower-oil steak; that comparison does not establish the values of other brands.
Follow that product's directions for transferring, covering, refrigerating and using the remainder. Storage instructions differ between products, so check them before choosing a tin that will take more than one meal to finish.
Look for the claim on the specific pack rather than assuming it applies across a brand. In its UK Tuna Shopper Report, the Marine Stewardship Council reported that 138 of 271 shelf-stable tuna products examined in February 2026 carried its label; that category finding does not identify the certification status of another tin.
Read the current product's ingredients and allergen declaration. GOV.UK explains that food businesses must identify regulated allergens, including fish, and the exact pack is the place to check the product you intend to use.
