One-person dinner cooks
If you are making a pasta bake, jacket potato or rice dish with other ingredients, a 145g or 160g tin gives you a specific size to assess against your recipe. Compare its drained weight to judge the amount of tuna.
Who is a single tin for?
A single tin is worth considering when the amount needed, the texture in the finished dish and any label requirements matter more than having several tins on hand.
Texture-led buyers
Chunks suit a dish where tuna is stirred through other ingredients. If you want firmer, more distinct pieces, compare steak: Marks & Spencer describes its spring-water tuna steak as firm.
Label-conscious buyers
Check the exact tin for ingredients, fish-allergen information, nutrition, drained weight and storage directions. NHS guidance on tuna intake is also relevant if you are pregnant or trying for a baby.
What matters when choosing a tin?
Start with the portion and the way you want the tuna to sit in the dinner, then compare packing liquids and the exact product label.
| Priority | What to check | Your needs |
|---|---|---|
| Amount for the meal | Check the tin’s net weight and its stated drained weight. Tesco and Princes have 145g spring-water chunk formats; Marks & Spencer lists 160g chunks. | I’m cooking for one and want to judge how much tuna will go into the dish, not count the packing liquid as tuna. |
| Texture | Compare chunks for stirring into other ingredients with steak when distinct pieces matter. Marks & Spencer describes its spring-water steak as firm. | Will the tuna be mixed through pasta or a potato filling, or do I want pieces that remain more noticeable? |
| Packing liquid | Read whether the tuna is packed in spring water, brine or oil. Compare the exact ingredients and nutrition panel, including salt and fat figures. | I want the packing ingredients to work with the sauce or seasoning I plan to add, rather than assuming the three formats are interchangeable. |
| Ingredients and allergens | Check the ingredient list and allergen information on the exact product. The Food Standards Agency identifies fish as an allergen. | If an ingredient or allergen affects my choice, I need the details for this tin rather than relying on its flavour or format name. |
| Leftovers | Read the pack’s instructions after opening. For its spring-water steak, Marks & Spencer says to transfer unused tuna to a non-metallic container, refrigerate it and eat it within two days. | If I will use only part of the tin, I need a plan for the remainder that follows that product’s directions. |
| Tuna in pregnancy | NHS guidance says that people who are pregnant or trying for a baby should have no more than four cans of tuna or two tuna steaks a week. | If this guidance applies to me, I need to consider tuna eaten across the week, not just in this dinner. |
Common buying mistakes
-
Counting the net weight as all tuna
Net weight includes the packing liquid, so it does not tell you how much drained tuna will go into your dinner.
Compare the stated drained weight when judging whether a tin suits the recipe and number of diners.
-
Choosing by packing liquid alone
Spring water, brine and oil are different ingredients, but the packing liquid alone does not tell you the tin’s salt or fat values.
Read the full ingredients and nutrition panel for the particular product before choosing how it fits your dish.
-
Opening more tuna than the meal needs
A multipack contains separate tins, while any tuna left from a tin you have opened needs to be stored according to that product’s instructions.
For an occasional one-person meal, consider a single tin. Marks & Spencer instructs buyers of its spring-water steak to transfer unused tuna to a non-metallic container, refrigerate it and eat it within two days; follow the directions on your own pack.
-
Judging pregnancy guidance one tin at a time
The NHS limit for people who are pregnant or trying for a baby concerns tuna eaten over a week, whether this dinner uses a whole tin or only part of one.
Account for tuna across meals: NHS guidance says no more than four cans of tuna or two tuna steaks a week.

Questions about single-tin tuna
Is one tin enough for a comfort dinner?
One tin may suit a one-person jacket potato, pasta bake or rice dish when the tuna is mixed with other ingredients. Tesco and Princes have 145g chunk formats, while Marks & Spencer lists 160g chunks; compare the drained weight with the amount your recipe needs.
Should I use chunks or steak in a tuna pasta bake?
Choose chunks if you want to stir tuna through the pasta and sauce. If firmer, more distinct pieces matter to you, compare steak: Marks & Spencer describes its spring-water tuna steak as firm.
How should I store tuna left from an opened tin?
Follow the instructions on the particular tin. For its spring-water tuna steak, Marks & Spencer says to transfer unused contents to a non-metallic container, refrigerate them and eat them within two days; do not assume every product has identical directions.
What is the UK guidance on tuna during pregnancy?
The NHS says that people who are pregnant or trying for a baby should have no more than four cans of tuna or two tuna steaks a week. The guidance concerns intake across the week, not just the tin used for one dinner.
What should I check if fish allergens matter?
Check the exact tin’s ingredients and allergen information rather than relying on its product name. The Food Standards Agency identifies fish as an allergen.
