Dinner-for-two planners
You want enough usable tuna for the recipe without judging a pack by its tin weight alone. Drained weight and the number of portions matter when deciding how many tins to open.
Who is choosing?
Simple-dish presentation buyers
You plan to leave the tuna visible in a salad or topping. Whether the product is labelled chunks or steak, and whether it needs draining, may matter more than it would in a sauce.
Sourcing-conscious shoppers
You want a stated basis for your choice, such as fishery certification, a catch method, a retailer policy or can-code traceability. Check that the statement applies to the exact tin you intend to use.
What matters when choosing?
Decide how the tuna will appear in the meal, then check the usable quantity and the exact variant’s label. A format that matters in a lightly dressed salad may matter less once the fish is mixed into a sauce.
| Concern | What to check | Who this matters to |
|---|---|---|
| Usable portions | Compare stated drained weights and add up the quantity your recipe calls for. | If I’m making pasta for two, I want to know how much tuna remains after draining rather than relying on the tin weight. About 33% of consumers put usable portions first. |
| Presentation and format | Check whether the tin says chunks or steak and whether the fish will stay visible in the dish. | For a lightly dressed salad or topping, I want a format that suits how I plan to serve the tuna. Around 27% of consumers make presentation and format their primary concern. |
| Recipe fit and handling | Read the packing medium, salt figure and instructions for any tuna left after opening. | If my dressing supplies the flavour, I want to choose the packing medium deliberately and know how to handle leftovers. Approximately 20% of consumers put recipe fit and handling first. |
| Sourcing information | Look for a catch-method, fishery-certification, sourcing-policy or traceability statement on the exact product. | When the sourcing statement shapes my choice, I need it to apply to the tin I’m buying, not just the brand. About 20% of consumers treat that as their primary need. |
Checks that are easy to miss

Using tin weight as the amount of tuna
A tin’s stated weight can include spring water, brine or oil. The drained weight is the more useful figure when the recipe calls for a quantity of tuna.
Check the drained weight on the pack and add together the tins you expect to use for two portions.
-
Assuming spring-water tins have identical labels
Tesco Groceries lists 0.90g salt per 100g drained for its researched spring-water multipack, while Sainsbury’s lists 0.12g per 100g drained for its researched single tin. Their stated instructions after opening also differ.
Read the ingredients, nutrition panel and storage instructions on the exact variant rather than using another tin as a guide.
-
Applying one sourcing claim to a whole range
Sainsbury’s describes pole-and-line catching and Marine Stewardship Council fishery certification for the researched spring-water product. M&S describes its researched chunks under its Forever Fish policy, while John West offers a can-code traceability tool. These statements have different scopes.
Check which claim appears on the product you choose and what it describes.

Overlooking who will eat the dinner
Tuna is fish, so check the actual can’s allergen declaration and do not serve it to someone with a fish allergy. For people who are pregnant or trying for a baby, the Food Standards Agency’s November 2024 guidance repeats the NHS advice of no more than four cans of tuna or two tuna steaks a week.
Account for tuna eaten during the rest of the week when that guidance applies.
Brands and ranges to consider
Tesco
Tesco Groceries lists own-label spring-water chunks in multipack formats that give a stated drained weight for planning portions.
- The researched 4 x 145g pack states a drained weight of 4 x 102g and identifies the tuna as Skipjack.
- Product details can change; check the current can label before using its ingredients or storage instructions.
Princes
Princes offers chunks in spring water, brine and sunflower oil for dishes such as pasta, salads and jacket potatoes.
- Tesco Groceries lists 4 x 102g drained weight for the researched 4 x 145g spring-water pack.
- Packing medium and label values vary by variant, so choose by the particular pack rather than the brand name alone.
John West
John West presents chunk, no-drain and recipe-oriented tuna formats, including a can-code traceability tool.
- A no-drain variant offers a preparation option when you would rather add tuna to a dish without draining it first.
- Check the exact variant’s packing medium and quantity; a no-drain label does not describe every John West tin.
Sainsbury’s
The researched Sainsbury’s spring-water tuna provides product-specific catch-method and fishery-certification statements.
- Sainsbury’s describes its researched spring-water tuna as pole-and-line caught and sourced from a fishery certified to the Marine Stewardship Council standard.
- The researched single tin instructs shoppers to transfer leftovers to a non-metallic container, refrigerate them and use them within one day. Follow the instructions on the tin you buy.
M&S
M&S presents spring-water chunks alongside a stated sourcing policy and pole-and-line catch method for the researched product.
- M&S says its researched spring-water chunks are pole-and-line caught and sourced under its Forever Fish policy.
- Check the statement and storage instructions on the exact pack; the retailer’s policy statement is not a description of every tuna variant.

Questions about tinned tuna
How many tins of tuna do I need for dinner for two?
Use the recipe’s required amount and each tin’s drained weight, rather than counting tins alone. Tesco Groceries lists 4 x 102g drained weight for its researched 4 x 145g multipack; add the drained quantities of the tins you plan to use before deciding whether they cover your recipe.
Should I choose tuna in spring water, brine or oil?
Choose the packing medium to suit your recipe: spring water leaves the dressing to the other ingredients, while an oil-packed tin brings oil into the dish. Check salt on the exact label rather than assuming the packing medium tells you the amount; the researched spring-water products from Tesco and Sainsbury’s list different salt figures.
What should I do with tuna left after opening a tin?
Transfer leftovers to a non-metallic container, refrigerate them and follow the time stated on the exact tin. The researched Sainsbury’s single tin instructs use within one day, while the researched Tesco product says to consume leftovers within two days.
Does tinned tuna count as an oily-fish serving?
No. The NHS classifies both fresh and canned tuna separately from oily fish, so a tuna dinner does not count towards an oily-fish serving.
What if someone eating the dinner is pregnant or trying for a baby?
Account for tuna eaten throughout the week, not just at this dinner. The Food Standards Agency’s November 2024 guidance repeats the NHS advice that people who are pregnant or trying for a baby have no more than four cans of tuna or two tuna steaks a week; the can described in that guidance is around 140g drained.
