Cooks assembling dinner straight away
A no-drain tinned format can go into pasta, a salad, a jacket potato or a wrap without draining. Fresh tuna steaks need chilled storage and cooking; check the instructions on the particular pack.
Who is each format for?
Shoppers choosing the packing liquid
Spring water leaves the dressing or sauce to you, while oil is already part of the packed product. The labelled energy and fat differ between Sainsbury's cited spring-water and sunflower-oil tuna steaks, so compare the exact products rather than generalising across tins.
Households planning for leftovers or dietary restrictions
Check the fish allergen declaration and the instructions after opening. NHS tuna guidance is also relevant if someone is pregnant or trying for a baby.
What should you check before choosing?
Decide whether the meal allows time to cook the fish, then choose a tinned format that suits how you will use it.
| Priority | What to check | Your needs |
|---|---|---|
| Preparation | Check whether a tin says no-drain or gives draining instructions. For fresh fish, follow the pack's cooking and chilled-storage directions; Sainsbury's cited defrosted yellowfin steaks give a 10-minute pan-fry instruction. | If dinner needs assembling straight away, I want tuna I can add without cooking; avoiding draining may save another step. |
| Piece size | Look for steak pieces when distinct pieces matter. Princes describes its sandwich tuna as a mix of chunks and flakes, a different format for mixing into a filling. | For a salad or jacket potato, I may want visible pieces. In a sandwich filling or sauce, chunks and flakes can be mixed through. |
| Packing liquid | Compare ingredients and nutrition per 100g on the exact tin. Sainsbury's lists 116kcal and less than 0.5g fat for its spring-water steak, versus 165kcal and 6.0g fat for its sunflower-oil steak; salt is 0.75g and 0.85g respectively. | If I am adding my own sauce or dressing, spring water leaves that choice open. If the recipe calls for oil, I want to account for what is already in the tin. |
| Storage | Check the date marking and the instructions after opening. The cited John West no-drain and Princes drained products direct users to refrigerate unused tuna and consume it within 2 days. | When I will use only part of a pack, its opening instructions help me plan the remaining portions. |
| Dietary checks | Read the current fish allergen declaration. If pregnancy guidance applies, check the NHS advice for cans of tuna and tuna steaks. | I need to know whether the fish is suitable for everyone eating the meal and whether NHS tuna guidance applies to anyone in the household. |
Common buying mistakes
-
Assuming all tinned tuna steaks have the same nutrition
Sainsbury's lists 165kcal and 6.0g fat per 100g for its sunflower-oil steak, compared with 116kcal and less than 0.5g fat for its spring-water version. Those figures describe these products, not every oil- or water-packed tuna.
Compare the exact labels per 100g and per serving, then choose the packing liquid for the dish.
-
Buying fresh tuna for a meal with no cooking time
Sainsbury's cited yellowfin steaks are sold defrosted, require chilled storage and give a 10-minute pan-fry instruction. They cannot simply be stirred into a meal like ready-to-eat tinned tuna.
Choose a ready-to-eat tin for an assembly-only dinner; choose fresh tuna when you can follow its cooking and storage instructions.
-
Overlooking instructions after opening
The cited John West no-drain and Princes drained tuna products specify refrigeration and use within 2 days after opening. GOV.UK says food whose pack instructs refrigeration after opening should be kept at 5°C or below.
Check the instruction on your pack before opening more than you plan to use.
-
Skipping household dietary checks
Tuna is fish, and the cited products declare it as an allergen. NHS guidance sets tuna limits for people who are pregnant or trying for a baby.
Read the current allergen label and check the NHS guidance if it applies to someone eating the meal.
Brand and retailer ranges
These examples show how formats vary within and between ranges; check the exact product rather than applying one pack's details to a whole brand.

Frequently asked questions
Should I choose tinned or fresh tuna for dinner tonight?
Choose ready-to-eat tinned tuna when you need to assemble dinner without cooking the fish; check whether the particular tin needs draining. Fresh tuna suits a cooked-steak meal if you can follow its chilled-storage and cooking instructions. Sainsbury's cited defrosted yellowfin steaks give a 10-minute pan-fry instruction.
How do spring-water and oil-packed tuna differ?
Choose the packing liquid for the recipe and compare the exact nutrition labels. Sainsbury's spring-water tuna steak lists 116kcal and less than 0.5g fat per 100g; its sunflower-oil version lists 165kcal and 6.0g fat per 100g. Those figures are specific to these two products.
How should I store tuna after opening it?
Follow the instructions on the pack. The cited John West no-drain and Princes drained products specify refrigeration and use within 2 days; GOV.UK says that when packaging instructs refrigeration after opening, the food should be kept at 5°C or below.
Does tinned tuna contain fish allergens?
Yes. Tuna is fish, and the cited tuna products declare fish as an allergen. Read the current label before serving it to anyone with a fish allergy.
What does NHS guidance say about tuna during pregnancy?
The NHS advises people who are pregnant or trying for a baby to have no more than 4 cans of tuna a week or no more than 2 tuna steaks a week, because tuna contains higher levels of mercury than other fish. That guidance applies to this group, not to all shoppers.
