For batch cooking, spring-water tuna chunks give you a plain base to season yourself; brine-packed chunks suit a savourier recipe, but compare salt per 100g drained. A 110g no-drain pot avoids the draining step for a smaller batch, while a larger tin may fit a recipe needing more tuna. Check drained weight and the pack’s instructions for leftovers before planning portions.
If tuna is going into pasta, rice bowls or jacket-potato fillings, compare the usable amount and packing medium as well as the tin’s stated size. Spring-water chunks provide a plain base for your own seasoning; brine changes the salt contribution.
A 110g no-drain pot may fit a small batch with less handling. A 145g or larger tin may leave unused tuna, so check its storage instructions before deciding how many portions to prepare.
Plan tuna across the whole week, not just one batch. The Food Standards Agency advises these groups to have no more than four medium cans of tuna or two tuna steaks a week.
Start with the recipe’s quantity and flavour, then check the nutrition panel and what you will do with any tuna left after opening.
| Priority | What to check | Your needs |
|---|---|---|
| Packing medium | Check whether the tuna is in spring water, brine or oil. Compare salt and fat using the same per-100g basis; Sainsbury’s lists 0.70g salt per 100g drained for its spring-water chunks, while its Princes brine listing gives 0.90g per 100g drained. | I want a plain base if I’m adding my own sauce and seasoning. For a savourier recipe, brine may fit, but I would account for the salt in the rest of the dish. |
| Usable quantity | Look for drained weight when a recipe specifies a precise amount of tuna. Do not treat the stated weight of a conventional tin as its drained yield; a no-drain pot is a different format. | Will one unit give me enough tuna for the portions I’m making, or will I need to open another? |
| Preparation | Check whether the pack needs draining and whether you want chunks or larger steak pieces. Tesco describes its 110g John West spring-water pot as no-drain; conventional tins require handling according to their labels. | For a small batch, avoiding the draining step matters to me. For a larger dish, I would check the quantity before choosing a smaller pot for convenience. |
| Leftovers | Read the particular pack’s instructions for transferring, refrigerating and using tuna after opening. The products described by Sainsbury’s, Princes, John West and M&S do not all give the same timeframe. | If I will use only part of the tin, I need a plan for the remainder that follows that product’s label. |
| Repeat meals | Count tuna used across the week as well as in one recipe. The Food Standards Agency advises people who are pregnant or trying for a baby to have no more than four medium cans or two tuna steaks a week; the NHS says canned tuna does not count as oily fish. | If I’m preparing tuna for several days, I want to consider the whole week’s meals rather than treating each portion separately. |
A conventional tin’s stated weight can include liquid. Joybuy describes a Princes 145g brine tin as containing 102g drained tuna, illustrating why the two figures are not interchangeable.
When the recipe needs a precise quantity, check the drained weight on the pack or weigh the tuna after draining.
Sainsbury’s lists 0.70g salt per 100g drained for its spring-water chunks and 0.90g per 100g drained for its Princes brine chunks. Other ingredients in a batch can add salt too.
Compare the panels on the products you are considering, then taste the finished recipe before adding salt.
Product instructions differ: the Sainsbury’s spring-water example says to use leftovers within one day, while the Princes, John West and M&S examples described in the research allow up to two days.
Refrigerate unused tuna promptly, transfer it where the label directs and follow the instruction on the pack you opened.
One batch can become several tuna meals. For people who are pregnant or trying for a baby, the Food Standards Agency advises no more than four medium cans of tuna or two tuna steaks a week.
Count the tuna in all meals planned for that week, including portions made from the same batch.
These examples illustrate particular UK product formats; a brand name alone does not tell you the packing medium, drained yield or storage instruction of another product.
Tesco lists a 110g No Drain Fridge Pot with tuna steak and a little spring water.
Sainsbury’s lists Princes Tuna Chunks In Brine in a 145g tin.
Its listed 145g tuna chunks in spring water provide a conventional plain-ingredient tin.
Its listed spring-water options include a 160g chunk tin and a 200g skipjack tuna-steak tin.
These single-unit tuna chunks offer spring-water, brine and sunflower-oil formats for batch recipes. Compare the pack and label with the amount and seasoning your dish calls for.

Spring-water chunks provide a plain packing medium for pasta and other batch recipes. Check the drained weight if your recipe specifies an exact tuna quantity.
The product instructions say to transfer unused tuna to a non-metallic container, refrigerate it and consume it within two days.

This brine-packed chunk tin is an option when that savoury packing medium fits the recipe. Its product description lists 0.9g salt per 100g drained; check the drained weight when measuring a batch.
The description warns that small bones may remain and says to refrigerate unused tuna for up to two days after opening.

A 160g spring-water chunk format for recipes calling for a larger single unit. Check the drained weight for a precise recipe quantity.
Check the pack’s nutrition panel before using protein figures to compare products: the product description’s protein wording and nutrition figure conflict. Its instructions say to refrigerate unused tuna and consume it within two days.

Choose this 145g chunk format when sunflower oil fits the recipe rather than when you need a spring-water base. Its description lists 6.4g fat per 100g drained; check the drained weight for precise quantities.
The product instructions say to transfer unused tuna to a non-metallic container, refrigerate it and consume it within two days.
Choose by the packing medium you want in the finished dish: spring water gives you a plain base, brine contributes a savourier one, and oil adds fat to the format. Compare the specific labels rather than assuming their nutrition is identical. Sainsbury’s lists 0.70g salt per 100g drained for its spring-water chunks and 0.90g for its Princes brine chunks on the same basis.
It can work when the recipe needs its quantity and avoiding draining matters. Tesco’s John West no-drain pot is 110g, while the conventional chunk tins discussed here include 145g and 160g formats. Check the amount the recipe requires before swapping one unit for another.
Refrigerate unused tuna promptly and follow the instructions on the pack, including any direction to move it out of the opened tin. The Sainsbury’s spring-water example says to use leftovers within one day, whereas the Princes, John West and M&S examples described here allow up to two days.
The Food Standards Agency advises people who are pregnant or trying for a baby to have no more than four medium cans of tuna or two tuna steaks a week. Count tuna across all the week’s planned meals, and check the pack and drained weight rather than assuming every single-unit product equals a medium can.
No. The NHS states that fresh and canned tuna do not count as oily fish, so a tuna batch does not fulfil the oily-fish part of its fish guidance.
