Weekly batch cooks making mixed dishes
If tuna is going into pasta bakes, fishcakes or bean fillings, chunks are easy to distribute across portions. Spring-water packs leave the choice of sauce and added oil to the recipe.
Who is this for?
Meal preppers comparing label values
If you plan portions using fat, salt or protein figures, compare the same quantity and nutrition basis on each pack. Packing medium and drained weight both matter.
Shoppers choosing texture or sourcing information
Steaks are worth considering when you want larger pieces in a salad or jacket-potato topping. For a catch-method, traceability or certification claim, check the particular tin rather than the brand name alone.
What should you check?
Start with the dish and the amount of tuna it needs, then compare packing liquid, label values and what will happen to any opened leftovers.
| Priority | What to check | Your needs |
|---|---|---|
| Packing liquid | Check whether the tuna is packed in spring water, brine or oil. If the recipe has its own sauce or dressing, decide whether the packing liquid fits it. | I’m making several different dishes and want to choose the seasoning and added oil for each one. |
| Usable quantity | Use drained weight, where shown, to work out the tuna available for a recipe; total tin weight includes liquid. Compare pack formats on that basis rather than by tin size alone. | One batch needs enough tuna for all its portions, without leaving more opened tuna than I can use. |
| Label values | Compare fat, energy, protein and salt using the same label basis. Princes Food and Drinks lists 0.5 g fat and 99 kcal per 100 g drained for its spring-water chunks, against 9.5 g and 180 kcal for its sunflower-oil chunks; these are figures for those products, not every tuna pack. | I’m portioning a recipe and need its ingredients’ label values to reflect the packing medium I actually buy. |
| Texture | Check whether the pack contains chunks or steaks. Consider whether tuna will be mixed through a filling or left in larger pieces on the plate. | For a pasta bake, I can mix in chunks; for a salad topping, I may want pieces that stay more distinct. |
| Opened-tin storage | Read the exact pack’s transfer, refrigeration and use-within instructions before choosing a large tin. Marks & Spencer gives a two-day window for some tuna products, but 24 hours for its 200 g oil-packed steak. | If a batch uses only part of a tin, I need a realistic plan for the remainder within that product’s stated timeframe. |
| Sourcing claims | Look for the certification mark or stated catch method on the specific product. Marks & Spencer describes particular tuna-steak products as pole-and-line caught; that does not establish the method for every tuna product. | A stated catch method or certification matters to me, so I’ll check the tin I intend to buy. |
Common buying mistakes
-
Using total tin weight as the tuna portion
The stated tin weight can include packing liquid, so it may not tell you how much fish will go into each serving.
Plan portions with drained weight where the label gives it, and use the same basis when comparing pack sizes.
-
Treating different packing liquids as interchangeable
Princes Food and Drinks lists different fat and energy values for its spring-water and sunflower-oil chunks, despite listing 23.5 g protein per 100 g drained for both. Its brine and spring-water chunks also have different stated salt values.
Choose the liquid for the finished recipe, then check the exact pack’s values before adding seasoning or oil.
-
Opening a large tin without planning the remainder
An opened tin may have a short, product-specific storage window. A larger format only fits the plan if its contents can be used in time.
Work out the batch quantity before shopping; transfer unused tuna as directed, refrigerate it and follow that pack’s use-within instruction.
-
Assuming a sourcing claim covers every product in a range
Catch-method and traceability statements can refer to particular tuna products rather than everything sold under a brand.
Check the exact tin or product listing for the catch method, traceability statement or certification mark you want.
Brand references
These ranges illustrate formats and label details to compare; a brand name alone does not determine the contents of a particular tin.
Princes
Princes lists tuna chunks in brine, spring water and sunflower oil, giving batch cooks a choice of packing liquid.
- Princes Food and Drinks publishes per-100 g drained nutrition figures for these chunk products, allowing comparison on the same stated basis.
- Check the precise variant: its spring-water and sunflower-oil chunks have different listed fat and energy values.
Tesco
Tesco Groceries lists own-label tuna alongside branded options in different pack sizes and packing liquids.
- Its tinned-tuna listing displays a price per kilogram of drained weight for relevant products, which provides a consistent quantity basis for comparison.
- Check each product’s drained quantity and label rather than assuming that two similarly sized tins contain the same amount of tuna.
John West
John West includes no-drain tuna formats as well as conventional tinned chunks, offering a choice in how portions are assembled.
- A no-drain format can remove a draining step when adding tuna to prepared meals.
- Check the packing medium and the basis of the nutrition figures on the particular pack before comparing it with drained tuna.
M&S
Marks & Spencer lists spring-water chunks and tuna steaks, including an 800 g steak format.
- Marks & Spencer gives product-specific nutrition and opened-storage instructions, and describes particular steaks as pole-and-line caught.
- Storage time differs between named products; check the chosen pack before planning leftovers.

Frequently asked questions
Should I buy tuna in spring water, brine or oil for batch cooking?
Choose spring water when the batch recipe supplies its own sauce or dressing, brine when its salt fits the planned dish, or oil when you want that packing medium in the result. Princes Food and Drinks lists different fat and energy values for its spring-water and sunflower-oil chunks, so compare the exact labels rather than treating the variants as interchangeable.
Which weight should I use to plan portions?
Use drained weight where it is shown: it describes the tuna after packing liquid has been removed. Total tin weight alone is not a like-for-like measure of usable fish when comparing packs.
How should I store tuna left in an opened tin?
Follow that product’s transfer, refrigeration and use-within instructions. Marks & Spencer specifies a non-metallic container and refrigeration for its spring-water chunks and an 800 g steak product, with use within two days; its 200 g oil-packed steak specifies consumption within 24 hours.
Does tinned tuna count as oily fish in UK guidance?
No. The NHS says fresh and canned tuna do not count as oily fish.
What does a best-before date mean for an unopened tin?
A best-before date concerns quality rather than safety, according to UK government food guidance. Check the tin’s date, storage and product instructions; do not treat that general distinction as a reason to ignore an individual product warning.
