For a Bonfire Night family meal, choose individually sealed cans if you may make several dishes or the number of diners could change; consider a larger tin when most of it will go into one shared dish. Plan portions using the drained quantity rather than the can’s net weight, then choose spring water, brine or sunflower oil to suit the recipe and check how to store anything left after opening.
If you are making a shared tuna dish, compare the number of cans and their drained contents with the amount your recipe needs. A larger tin may mean fewer cans to open, while a multipack lets you keep any unneeded cans sealed.
For jacket potatoes, sandwiches or pasta, compare the spring-water and sunflower-oil versions on their labels rather than assuming the packing liquid makes no difference. Asda Groceries lists both in four-can formats.
If attendance might change or you want tuna for later lunches, individually sealed cans let you open only what you need. Asda Groceries and Princes Food and Drinks list four-can spring-water formats, and John West lists a four-can pack.
Work out how the tuna will be served before choosing a pack: one shared dish and several smaller servings call for different ways of opening and storing cans.
| Concern | What to check | Who this matters to |
|---|---|---|
| Enough usable tuna | Compare can count and drained quantity with the portions needed for the planned dish. Net weight includes packing liquid. | For a shared pasta bake, I need enough tuna without opening more cans than the recipe uses. About 40% of consumers put portion and pack-size planning first. |
| Packing liquid | Check whether the tuna is in spring water, brine or sunflower oil, and compare fat and salt on the exact label using the same stated weight basis. | If I am adding my own dressing or sauce, I want to choose the tuna’s packing liquid separately from those ingredients. Roughly 30% of consumers make packing liquid and label values their primary concern. |
| Opening and leftovers | Check whether the cans open easily and follow the pack’s instructions for unused contents after opening. | When plans may change, I want to leave spare cans sealed for another meal rather than store opened tuna. Around 30% of consumers prioritise that flexibility and leftover control. |
A pack marked 4 x 145g includes packing liquid, so that figure is not necessarily the amount of drained tuna going into the dish.
Use the drained quantity on the exact pack, where shown, when checking it against your recipe.
Asda Groceries’ four-can spring-water and sunflower-oil products have different per-100g drained fat and energy values. The difference applies to those products, not automatically to every brand.
Compare labels on the same stated basis, then account separately for ingredients you add to the finished dish.
Once a can is opened, any unused tuna needs the storage treatment stated on its label. Asda Groceries instructs buyers of its spring-water four-pack to transfer leftovers to a suitable non-metallic container, cover and refrigerate them.
Open cans as needed and follow the chosen product’s instructions for using refrigerated leftovers.

Separate cans suit a meal where you may need to open tuna in stages or keep some for later. The title identifies six 145g cans in spring water; check the drained quantity on the pack when planning portions.

Four separate cans can be opened as needed for a family dish or several servings. This is the brine variant; check its salt value on the label if that affects your choice, and use drained quantity to plan portions.

Consider this four-can option when sunflower-oil tuna suits the planned dish and you want to open cans separately. Check the on-pack basis for nutrition values before comparing them with another product’s per-100g drained figures.

Four 125g cans offer a spring-water multipack for servings prepared at different times. The stated net weight per can differs from a 145g format, so compare drained quantity for your recipe; check the exact label if a no-drain feature matters.

The listed six-pack may suit a gathering where tuna will be used across several servings. The title specifies 145g cans in brine; check the outer-pack configuration, drained quantity and salt value on the exact pack before planning the meal.
Choose according to the recipe and compare the exact labels: spring-water and sunflower-oil versions can differ in fat content, while salt is worth checking on a brine variant. If the bake includes mayonnaise, cheese or another dressing, consider those ingredients separately from the tuna’s label values.
Follow the chosen pack’s instructions rather than treating an opened can as cupboard-stable. Asda Groceries instructs buyers of its 4 x 145g spring-water tuna to transfer unused contents to a suitable non-metallic container, cover and refrigerate them, then use them within two days.
No. The NHS states that fresh and canned tuna do not count as oily fish; choosing a sunflower-oil packing liquid does not change that classification.
