For one small tea where you expect to use the whole tin, Sainsbury’s 227g chopped tomatoes are labelled as one serving. If you need a finer tomato base or are cooking a larger sauce, consider a finely chopped 400g tin such as Tesco’s, but plan what to do with any remainder. Compare salt per 100g and follow the storage directions on the pack you buy.
A tin you can use in one meal may be more convenient than opening a larger tin and storing the remainder. Sainsbury’s labels its 227g chopped tomatoes as one serving; Tesco and ASDA label their cited 400g tins as two servings.
A plain tomato base leaves room to adjust the recipe. Check whether chopped pieces or a finely chopped texture will work better in the sauce you plan to make.
Salt declarations differ between tomato tins. Comparing the per-100g figures also leaves room to consider other ingredients in the finished meal, such as cheese, stock or sauce.
Start with the amount your recipe uses, then check texture, the per-100g salt declaration and directions for any leftovers.
| Priority | What to check | Your needs |
|---|---|---|
| Tin size | Check the weight and labelled servings against the amount your recipe needs. Sainsbury’s labels its 227g tin as one serving; the cited Tesco and ASDA 400g tins each indicate two. | I’m making one small tea and would rather use the whole tin, or I have another meal planned for the remainder. |
| Tomato texture | Look for “finely chopped” if smaller pieces would suit the sauce. Tesco describes its Italian Finely Chopped Tomatoes as finely chopped; Napolina describes its chopped tomatoes as chunky. | If noticeable tomato pieces are an issue at our table, I want to choose the texture before I start cooking. The finished sauce will still depend on the recipe. |
| Salt | Compare salt per 100g on the exact tins. Tesco lists 0.03g for its Italian Finely Chopped Tomatoes and ASDA lists 0.01g for its Chopped Tomatoes. The NHS gives age-specific daily salt limits for children, so consider the whole meal rather than the tomatoes alone. | I want to see what the tomato base contributes before adding other ingredients and seasoning. |
| Leftovers and labels | Follow the opened-pack instructions for the tin bought: Tesco says to use refrigerated leftovers within two days; ASDA says to transfer them to a non-metallic container, refrigerate and use within four days. Check the current ingredients and allergen information when relevant. | A 400g tin works for me if I can use the remainder within its pack instructions. For an allergy or intolerance, I also need to check the can I actually bought. |
The cited Tesco and ASDA 400g tins are labelled as two servings, while Sainsbury’s 227g tin is labelled as one. A small recipe may therefore leave opened tomatoes.
Choose the amount the recipe will use, or plan the next meal and follow the tin’s storage instructions.
A flavoured tomato product may contain ingredients or seasoning that differ from a plain chopped-tomato base.
Read the ingredients and salt declaration on the exact product, then decide whether to season a plain base yourself.
Napolina describes its chopped tomatoes as chunky, whereas Tesco identifies its Italian Finely Chopped Tomatoes as finely chopped. That distinction matters when visible pieces are unwelcome.
Check the texture description before buying; blending or further cooking remains a recipe choice, not a guarantee of acceptance.
An online description may not represent the ingredients and allergen information on the can in hand.
For a child with an allergy or intolerance, read the current pack before preparing the meal.

The 400G chopped-tomato tin is an option for a sauce that uses that quantity. For a smaller tea, check how much the recipe needs and read the can’s instructions before keeping any remainder.
Choose the size your recipe will use. Sainsbury’s labels its 227g chopped tomatoes as one serving, while the cited Tesco and ASDA 400g tins are labelled as two; a 400g tin makes more sense if you will use the remainder according to its storage instructions.
A finely chopped tin is a starting point for a sauce with smaller pieces. Tesco describes its Italian Finely Chopped Tomatoes as finely chopped, whereas Napolina describes its chopped tomatoes as chunky; the finished texture still depends on how you cook the sauce.
Follow the instructions on the exact tin. Tesco says to refrigerate unused contents and use them within two days; ASDA says to transfer leftovers to a non-metallic container, refrigerate and use within four days.
Compare the salt figure per 100g on each pack, then consider the other ingredients in the meal. The NHS gives maximum daily salt amounts of 3g for children aged 4 to 6 and 5g for ages 7 to 10; the tomato tin is only one potential contributor.
Read the ingredients and allergen information on the current can before using it, rather than relying only on an online listing. Product information can change, so check the exact item being prepared.
