Taco and tostada cooks who want visible pieces
If tuna is the topping rather than part of a mixed filling, inspect steak and fillet formats first. Tesco lists steaks separately from chunks, while M&S lists both steaks and fillets.
Who is choosing?
People assembling a dish with richer ingredients
When avocado, cheese or crema is already in the meal, spring-water or brine-packed tuna offers a different starting point from olive-oil tuna. Check the ingredient list and nutrition panel on the tin you choose.
Shoppers prioritising sourcing information
If catch method, certification or traceability determines your choice, look for the claim on the exact product. Princes publishes tuna sourcing commitments, and Sainsbury's has stated a commitment for its own-label canned tuna; neither statement replaces checking the current pack.
What matters when buying?
Decide whether the tuna needs to hold its shape on top of the dish or blend into a filling. Then consider what its packing medium contributes and which pack details matter to you.
| Concern | What to check | Who this matters to |
|---|---|---|
| Visible tuna pieces | Look for steak, loin or fillet in the product name; check the net or drained weight for the amount you plan to serve. | If tuna sits on a taco or tostada, I want recognisable pieces rather than fish that disappears into the filling; about 33% of consumers put visible texture first. |
| Richness from the tin | Check whether the tuna is packed in olive oil or another oil, and read the ingredients and per-100g nutrition panel. | For a simply dressed topping, I want the packing medium to contribute flavour without making a separate dressing; roughly 27% of consumers make that richness their primary concern. |
| A non-oil base | Confirm spring water or brine on the label; compare the stated fat and salt values for the products under consideration. | With avocado or crema already in the meal, I would rather choose tuna without oil as its packing medium; about 20% of consumers prioritise that choice. |
| Sourcing information | Find the certification, catch-method or traceability wording for the exact tin, not just a general brand statement. | Before choosing tuna for guests, I want to know which sourcing claim applies to the pack I am serving; approximately 20% of consumers put that assurance first. |
Checks worth making
-
A premium-looking tin does not tell you the cut
Steaks and fillets are the formats to inspect for a prominent topping; chunks are more practical when the tuna will be mixed through a filling. The design of the pack does not establish its texture.
Read the cut and packing medium first, then check how much tuna the tin provides.
-
Oil-packed tuna changes the ingredient profile
For two different M&S products, the olive-oil tuna steak lists 12.3 g fat per 100 g and the spring-water chunks list 0.6 g per 100 g. Because the cuts also differ, those figures should not be treated as a comparison of every oil- and water-packed tin.
If the dish already contains avocado, cheese or an oil-based dressing, compare the exact products before deciding whether you want oil-packed tuna too.
-
A brand sourcing statement is not the whole pack label
Princes describes company-wide tuna sourcing commitments, while Sainsbury's made a statement about its own-label canned tuna in 2023. Such statements do not establish the ingredients or catch-method wording on a different product.
When a particular certification or catch method is decisive, check how it is stated for the tin you intend to buy.
-
Serving and leftover instructions matter
Tinned tuna contains fish. Opened-pack instructions can also differ: the cited M&S tuna steak and John West No Drain product say to refrigerate and consume within two days, while the Tropical Sun product information specifies 24 hours.
Read the current allergen and storage instructions before serving guests, and follow the directions for the pack you open.
Brands and ranges to consider
These are product-line examples, not a claim that every tin from a brand has the same cut, packing medium or sourcing information.
M&S
M&S lists tuna steaks, Collection Ventresca fillets and pole-and-line-caught albacore loins for shoppers comparing cuts.
- Its tuna steak in olive oil has product-level information on ingredients, nutrition, fish allergen and opened-pack storage.
- M&S advises that product information can change, so use the current tin label for the final check.
John West
The No Drain Tuna Steak in Spring Water 3 x 110g is a steak-format option without olive-oil packing.
- Its product information describes a resealable pack containing tuna, spring water and salt.
- It contains fish; the listed instructions say to refrigerate after opening and consume within two days.
Princes
Princes offers formats ranging from chunks to Ocean Select yellowfin tuna steaks, including olive-oil variants with added flavouring.
- Princes says its tuna is MSC certified and that it can trace its canned tuna to the original boat.
- Check the selected product for its cut, oil, ingredients and applicable sourcing wording rather than transferring details from another Princes tin.
Sainsbury's
Sainsbury's lists own-label tuna chunks in spring water and brine, both relevant to a mixed filling.
- In 2023, Sainsbury's stated that its own-label canned tuna was MSC certified and pole-and-line caught.
- Check the current tin for the particular sourcing wording and packing medium you require.
Tesco
Tesco's tinned-tuna category lists multiple brands and separates steaks, chunks and packing media for comparison.
- Its listings include Princes Ocean Select Yellowfin Tuna Steak in Olive Oil with Lemon for a recipe that suits that flavour.
- A category listing does not replace the current product label when checking full ingredients and nutrition.
Tuna formats compared
This scenario-led sequence considers visible texture, packing medium and how specifically a flavour fits the recipe. It is not a sales ranking or a product test; each row retains its original supplier.
| Sequence number | Product | Main specifications | Reason to consider | Supplier |
|---|---|---|---|---|
| 1 | M&S Eat Well Tuna Steak in Olive Oil 200 g | Tuna steak; olive oil; 200 g. | M&S describes this as pole-and-line-caught skipjack tuna in olive oil. The steak cut and packing medium make it a candidate when tuna will be a visible, rich-tasting topping. | M&S |
| 2 | John West No Drain Tuna Steak in Spring Water 3 x 110g | Tuna steak; spring water; 3 x 110g; resealable pack. | The Joybuy product information describes a steak-format alternative for shoppers who want visible pieces without olive-oil packing. Its opened-pack instructions still need to be followed. | Joybuy |
| 3 | Princes Ocean Select Yellowfin Tuna Steak in Olive Oil with Lemon 160g | Yellowfin tuna steak; olive oil with lemon; 160g. | Tesco lists this flavoured variant. Consider it when lemon suits the planned seasoning; the flavour makes it less flexible than an unflavoured tin. | Tesco |

Princes Tuna Chunks in Brine 4 x 145g x 12 Packs
Brine-packed chunks are suited to tuna mixed through beans, rice or a sauce rather than displayed as whole steak pieces.

Frequently asked questions
Should I use tuna steaks or chunks for tacos and tostadas?
Use steaks or fillets when you want recognisable pieces on top; use chunks when the tuna will be mixed into beans, rice or sauce. Check the cut on the exact tin, as both formats appear in retailer tuna ranges.
Should the tuna be packed in olive oil, spring water or brine?
Choose by what the rest of the dish supplies: olive oil contributes richness, while spring water or brine can provide a non-oil base alongside avocado or crema. M&S lists 12.3 g fat per 100 g for its olive-oil tuna steak and 0.6 g per 100 g for its spring-water chunks; these are different cuts as well as different packing media. Compare the nutrition and salt values on the tins you are considering.
How should I store tuna left after opening a tin?
Follow the instructions for the product you open. The cited M&S tuna steak says to move unused contents to a non-metallic container, refrigerate and eat within two days; the John West No Drain listing also specifies refrigeration and consumption within two days. Other products may give a different period.
What should I check before serving tinned tuna to someone with an allergy?
Check the current physical label: tuna contains fish, a regulated allergen. GOV.UK says that prepacked food containing any of the 14 regulated allergens must label them clearly. Do not rely on an older product description when serving someone with a fish allergy.
Do MSC, pole-and-line and traceability claims mean the same thing?
No. MSC refers to a certification programme, pole-and-line identifies a stated catch method, and traceability concerns information about a product's supply chain. Check which claim applies to the exact tin rather than assuming one statement establishes the others.
