For a tuna-led family dinner, compare drained weight rather than tin size alone: Tesco Groceries lists a 400g single tin, while its 145g spring-water tin contains 102g drained tuna. A standard tin can suit a pasta bake or salad when tuna is an add-in; if tuna will be a substantial ingredient across several plates, check the larger tin’s declared drained weight before choosing.
If tuna is a substantial ingredient across several plates, compare the drained quantity in a larger single tin with that in a standard tin. Tesco Groceries states that its 145g spring-water tin contains 102g drained tuna.
A regular tin may suit a dish built around pasta, beans, vegetables or potatoes when the recipe calls for a smaller amount of tuna.
Compare drained weight, packing liquid and ingredients, then check fish-allergen information and the instructions for any leftovers.
Decide how much tuna the dish needs after draining, then compare labels for the ingredients and handling details that matter to your household.
| Priority | What to check | Your needs |
|---|---|---|
| Drained quantity | Check drained weight separately from net weight. Tesco Groceries states that its 145g spring-water tin contains 102g drained tuna; its listing also includes a 400g single tin whose declared drained weight should be checked on the label. | Will tuna be a substantial ingredient on several plates, or just an addition to a larger dish? |
| Packing liquid | Compare ingredients and nutrition per 100g drained for the tins you are considering. Tesco Groceries lists skipjack tuna and spring water as the ingredients of its 145g tin; Princes lists tuna and spring water for its chunks. | I want the packing liquid and ingredients to work with the sauce or dressing I have planned. |
| Serving and storage | Check the fish-allergen label and the instructions after opening. Tesco Groceries says to transfer unused tuna from its 145g tin to a non-metallic container, cover, refrigerate and consume within two days. | If the recipe uses only part of a tin, I need to know how to store the rest. |
| Fish type | Do not count canned tuna as oily fish: the NHS explicitly excludes fresh and canned tuna from that category. | I’m planning an oily-fish meal, so tuna would not serve that purpose. |
Tesco Groceries states that its 145g spring-water tin contains 102g after draining. The number on the front of a tin may therefore overstate the amount a recipe can use.
Compare declared drained weights and decide whether tuna is the main ingredient or an add-in.
The NHS describes a fish portion as around 140g, while Tesco Groceries gives 102g drained tuna for its 145g tin. One such tin is less than that approximate portion before it is shared.
For a tuna-led meal across several plates, check the drained quantity of a larger single tin; use a standard tin where a smaller amount fits the recipe.
The NHS says fresh and canned tuna do not count as oily fish.
If an oily-fish meal is what you are planning, choose a different fish for that meal.
Tuna contains fish, and leftovers need handling according to the tin’s instructions. Tesco Groceries directs shoppers to refrigerate unused contents in a covered, non-metallic container and consume them within two days.
Check allergen information before serving and follow the storage directions on the tin you open.
Tesco Groceries lists both a 145g spring-water tin and a 400g single tin of tuna chunks, giving shoppers two net sizes to consider for a family dish.
Princes lists tuna chunks in spring water in a 145g size as well as multipack formats.
John West has a no-drain tuna steak format for meals where draining is inconvenient, alongside conventional chunk multipacks listed by Sainsbury’s Groceries.
This 145g tin is an option for family dishes where tuna is an add-in. Check its drained weight before relying on one tin for a tuna-led meal.

It can work as an add-in, but check the amount before making tuna the main ingredient for several people. Tesco Groceries states that its 145g spring-water tin contains 102g drained tuna; the NHS describes a fish portion as around 140g.
Choose according to your recipe and compare the actual ingredient and nutrition labels. Tesco Groceries lists skipjack tuna and spring water for its 145g tin; do not assume tins packed in different liquids have the same ingredients or drained quantity.
No. The NHS states that fresh and canned tuna do not count as oily fish, so a tuna dinner does not fulfil an oily-fish meal plan.
Yes, within the NHS pregnancy guidance: it says not to eat more than four cans of tuna or two tuna steaks a week. Count tuna eaten throughout the week, not just at one family dinner.
Follow the instructions on the tin you use. Tesco Groceries says to transfer unused tuna from its 145g product to a non-metallic container, cover, refrigerate and consume within two days; the Joybuy listing for John West no-drain tuna also specifies refrigeration and consumption within two days.
