Cooking a shared dinner
If tuna is going into a pasta bake, jacket-potato filling, melt or rice dish, check the drained weight before deciding how many tins the recipe needs.
Who is each format for?
Making a quick meal with less mess
A no-drain or ready-drained format suits a potato, toastie or pasta dish when you want to add the tuna without tipping away packing liquid first. John West and Princes describe products in these formats as ready to use.
Checking seafood sourcing
If catch method or certification matters to you, look for the statement on the particular tin. The sourcing information given for one product should not be assumed to cover every product from its brand or retailer.
What should you check?
Start with the amount of tuna your dish needs, then decide whether preparation, packing medium or texture changes which tin you would use.
| Priority | What to check | Your needs |
|---|---|---|
| Usable quantity | Compare drained weight where it is stated, rather than treating total pack weight or tin count as the amount of fish. Tesco lists 280g drained weight for its 400g spring-water tin. | I am mixing tuna through several portions and want to know how much will remain after draining. |
| Preparation | Check whether the exact product needs draining. John West describes its No Drain spring-water range as ready without draining; Princes describes its drained range as ready to use. | For a quick jacket potato or toastie, I would rather open a tin and add the tuna straight away. |
| Packing medium and texture | Check whether the tin contains spring water, brine or oil, and whether it holds chunks or steak. Marks & Spencer describes its sunflower-oil tuna steak as having a moist, rich texture. | Chunks will be mixed into my pasta bake, but I might choose a different texture when the tuna is more prominent on the plate. |
| Ingredients and labelling | Read the individual tin’s ingredients, allergen information, nutrition values and any warning about bones. Compare nutrition figures on the same stated basis, such as per 100g drained. | I want to check what is in the tuna before adding other ingredients to the meal. |
| Sourcing | Look for a catch-method statement or certification mark on the particular product. Sainsbury’s describes its checked spring-water chunks as pole-and-line caught and MSC certified. | Sourcing information matters to me, so I will check the tin I am buying rather than rely on the retailer’s name. |
| Leftovers | Read the tin’s instructions for transferring, refrigerating and using contents after opening. Food Standards Scotland advises following the food label for storage after opening. | If I only use part of a tin, I need to know how to store the rest. |
Common buying mistakes
-
Treating pack weight as drained weight
Spring-water tins contain packing liquid, so the weight on the front of a pack does not necessarily tell you how much tuna will go into dinner.
Check the drained weight when planning portions or comparing different pack sizes.
-
Assuming every spring-water tin is no-drain
Standard chunks and products expressly labelled no-drain are different preparation choices. The packing medium alone does not establish whether a tin is ready to add directly to a dish.
If avoiding the draining step matters, check that the exact tin says no-drain or ready-drained.
-
Using one tin’s label for another
Ingredients, nutrition values and instructions for opened contents are product-specific, including within a brand’s range.
Read the current tin for allergens, any bone warning and storage directions before cooking or keeping leftovers.
-
Extending a sourcing claim across a whole range
A catch-method statement or certification mark identifies the product to which it applies, not necessarily every tuna tin sold under the same name.
Check the mark or wording on the individual product when sourcing affects your choice.

Frequently asked questions
How do I compare the amount of tuna in different tins?
Use the drained weight where it is stated, because the total pack weight also includes packing liquid. For example, Tesco Groceries lists 280g drained weight for its 400g spring-water chunks tin; check the corresponding figure on another product before comparing portions.
Should I choose spring water, brine or oil for a pasta bake?
Spring-water or brine-packed chunks can be drained and mixed into the other ingredients; check which medium the exact tin uses and its preparation instructions. If you want the oil-packed tuna’s character in the finished dish, M&S describes its sunflower-oil steak as moist and rich. Compare the individual ingredient and nutrition labels rather than treating the formats as interchangeable.
What should I do with tuna left in an opened tin?
Follow that product’s instructions for transferring, refrigerating and using the contents. Food Standards Scotland advises checking the label for whether food needs refrigeration after opening; instructions can differ between tuna products.
Which allergen and bone checks matter?
Tuna is fish, so read the current ingredient and allergen label, particularly if the tin is going into a shared dish. Check and follow any warning that small bones may remain.
