For batch cooking across several meals, a four-pack lets you open cans as needed; for one recipe that uses a larger quantity at once, consider a larger individual tin. Plan with the drained weight rather than the outer pack weight: Tesco Groceries lists 408g drained tuna for its 4 × 145g brine pack. Check the packing medium and the exact label’s instructions for any leftovers.
A four-pack gives you separate cans for a pasta bake, jacket-potato filling or sandwiches without opening the whole pack at once. Check the drained quantity against each recipe: Tesco Groceries lists 102g drained per can, or 408g across its 4 × 145g brine pack.
If two packs have similar outer weights, their drained weights still need checking before you decide how much tuna each will provide. Keep a temporary offer separate from a regular-price comparison.
When tuna appears in several planned meals, check the salt figure and fish-allergy information on each exact product. Plan what you will do with any opened can; the Marks & Spencer spring-water tin instructs shoppers to refrigerate unused contents in a non-metallic container and eat them within two days.
Start with the amount your recipes will use, then choose a can format and packing medium that fit how you intend to divide the meals.
| Priority | What to check | Your needs |
|---|---|---|
| Drained quantity | Find the drained weight per can and multiply it by the can count. Tesco Groceries lists 4 × 102g drained, or 408g, for its 4 × 145g brine pack; the 145g can weight includes liquid. | I want to know how much tuna I can divide between recipes, not just how much the sealed cans weigh. |
| Can format | Compare the number and size of cans with the quantity needed each time. The cited John West multipack contains 4 × 125g cans; the Marks & Spencer spring-water example is one 160g tin. | Separate cans suit meals I will make on different days. If one recipe calls for a larger amount at once, I can consider a larger single tin. |
| Packing medium and salt | Check whether the exact variant is packed in spring water, brine or oil, then read its ingredients and salt figure per 100g. Tesco Groceries lists 1.00g salt per 100g drained for its cited brine pack. | The packing liquid needs to suit my recipe, and I may want to compare salt figures between the particular tins I am considering. |
| Opened-can storage | Read the instructions on the tin before planning leftovers. Marks & Spencer instructs shoppers to transfer unused spring-water tuna to a non-metallic container, refrigerate it and eat it within two days. | If a recipe uses only part of a can, I need a plan for the remainder within that product’s stated storage period. |
The stated can weight includes liquid. Tesco Groceries lists 408g drained tuna for its cited 4 × 145g brine pack, so using 580g as the recipe quantity would overstate what that pack provides.
Use the exact pack’s drained weight when dividing tuna between batches; where the label gives a per-can figure, multiply it by the number of cans.
An opened remainder needs to fit the product’s storage instructions. Marks & Spencer directs shoppers to transfer unused contents from its spring-water tin to a non-metallic container, refrigerate them and eat them within two days.
Before opening a larger tin or several small ones, decide which planned meal will use any remainder and follow the instructions on those exact cans.
The NHS says fresh and canned tuna do not count as oily fish. For anyone planning tuna meals during pregnancy, NHS 111 Wales guidance also says not to eat more than four cans of tuna or two tuna steaks in a week.
Keep those distinctions in mind when planning repeated tuna meals, rather than treating a multipack as a single meal.
These examples illustrate pack formats and label details to compare; each figure belongs to the particular product cited, not every tin from that brand.

It depends on the exact pack. Tesco Groceries lists 4 × 102g drained tuna, or 408g total, for its cited 4 × 145g brine multipack; check another product’s label rather than assuming it has the same drained weight.
Use drained weight to plan how much tuna will go into the food. Net can weight includes the packing liquid, so it does not by itself tell you the quantity of drained tuna available for a pasta bake or filling.
Follow that product’s storage label. For its spring-water tin, Marks & Spencer says to put unused contents in a non-metallic container, refrigerate and eat them within two days; plan the next meal accordingly.
No. The NHS states that fresh and canned tuna do not count as oily fish, so a tuna meal should not be counted as an oily-fish portion when planning fish meals.
NHS 111 Wales pregnancy guidance says not to eat more than four cans of tuna or two tuna steaks in a week. When planning several tuna meals, count tuna eaten across the week rather than considering only one batch.
