Salt-conscious Easter cooks
If you are making sauces, stews or pasta bakes, the tin’s salt declaration helps you account for one ingredient before seasoning the finished dish.
Who is this for?
The useful choice depends on both the salt figure and what the tomatoes need to do in the recipe.
Households cooking several tomato dishes
When buying tins for more than one meal, compare salt per 100g alongside pack quantity, tomato texture and the storage instructions for opened tins.
Texture-led home cooks
Chopped tomatoes, finely chopped tomatoes and whole cherry tomatoes bring different-sized pieces to a sauce. Decide which format the dish calls for before comparing salt figures.
What should you check?
Start with the nutrition declaration on the tin, then check whether its texture and quantity fit the meals you are planning.
| Priority | What to check | Your needs |
|---|---|---|
| Declared salt | Compare salt in grams per 100g on the exact tins. Check how much tomato the recipe uses, then account for salt added through other ingredients or seasoning. | I want to compare tins before seasoning an Easter sauce. In the Food Standards Agency Northern Ireland and Ipsos 2022 tracker, 42% of respondents said they would be more likely to buy food reduced in salt than the regular version; the question covered food generally, not tinned tomatoes. |
| Nutrition labels | Read the numeric salt declaration even if a front-of-pack traffic-light label is present. Compare per-100g figures rather than treating different stated servings as equal. | A quick front-of-pack indication is useful to me, but I also want the number behind it. The Food Standards Agency and Ipsos Northern Ireland 2024 tracker, based on 611 interviews, reported that 49% actively used traffic-light labelling when shopping for food; this was not specific to tomatoes. |
| Tomato texture | Check whether the tin contains chopped pieces, finely chopped tomatoes or whole cherry tomatoes. Match the format to the texture wanted in the finished dish. | For a sauce with visible pieces, I would consider chopped tomatoes; for smaller pieces, finely chopped tomatoes. Whole cherry tomatoes make sense when their shape suits the recipe. |
| Pack and storage | Check the number and size of tins against the dishes planned. Read the exact pack’s instructions for storing any opened contents. | If I am cooking several meals, a multipack may suit the plan; for one dish, I want to avoid buying more tins than I intend to use. |
Common buying mistakes
-
Assuming plain tinned tomatoes have identical salt figures
Product declarations differ. ASDA Groceries lists 0.01g salt per 100g for its Just Essentials chopped tomatoes, while its Mutti finely chopped tomato listing states 0.30g per 100g; the products also differ in format.
Read the salt figure on each tin you are considering, and compare similar tomato formats where the recipe allows.
-
Comparing a serving with 100g
A half-can figure describes a different quantity from a per-100g figure. Comparing those numbers directly can obscure which tin has the lower declared salt concentration.
Use the per-100g declarations for the initial comparison, then consider the amount going into your dish.
-
Seasoning before considering the whole sauce
The NHS notes that daily salt includes what is already in food and what is added during or after cooking. A tomato tin is only one part of a sauce that may also contain seasoned ingredients.
Check the other ingredients and taste the cooked dish before deciding whether to add salt.
-
Choosing salt alone and overlooking texture
Whole cherry tomatoes will not give the same pieces as finely chopped tomatoes. That difference can matter in a pasta sauce or casserole even when both tins have suitable salt declarations.
Choose the tomato format for the dish first, then compare the salt figures of suitable tins.
Brand and retailer references
These examples show how particular product declarations and tomato formats differ; check the current tin before buying.
ASDA Just Essentials
A standard chopped-tomato option for sauces and casseroles.
- ASDA Groceries lists 0.01g salt per 100g for its 400g Just Essentials Chopped Tomatoes, using hob-heated nutrition values.
- Compare the declaration on the tin you buy, particularly if the recipe calls for a different tomato format.
M&S
Its Organic Italian Chopped Tomatoes offer an organic chopped format.
- Marks & Spencer lists 0.03g salt per 100g for this product.
- Check the current pack and whether the chopped texture suits the dish.
Sainsbury’s
An own-label chopped-tomato option with a stated nutrition declaration.
- Sainsbury’s lists 0.07g salt per 100g for its 400g Chopped Tomatoes.
- Check the current pack declaration and local availability when planning the shop.
Napolina
Chopped tomatoes described by Napolina as chunky and suited to thick sauces.
- Napolina states 0.10g salt per 100g for its chopped tomatoes.
- If minimising declared salt leads the decision, compare that figure with other chopped tins rather than choosing by texture alone.
Mutti
A finely chopped format for dishes where smaller tomato pieces are wanted.
- The ASDA Groceries listing for Mutti Finely Chopped Tomatoes states 0.30g salt per 100g and lists salt as an ingredient.
- Its finer texture serves a different purpose from standard chopped or whole cherry tomatoes; compare the salt declaration if that is your main priority.
Tesco
A retailer reference for the Napolina Chopped Tomatoes 400g listing.
- Tesco Groceries lists 0.10g salt per 100g for that Napolina product.
- Use the declaration for the particular product, rather than treating a retailer’s branded listing as a figure for its own-label tins.

Questions about choosing tinned tomatoes
How can I choose a lower-salt tin without a “reduced salt” label?
Compare the salt declaration per 100g on tins in a format that suits your recipe. For example, ASDA Groceries lists 0.01g per 100g for Just Essentials Chopped Tomatoes using hob-heated values, while the Sainsbury’s Chopped Tomatoes listing states 0.07g per 100g. Check the current tin rather than assuming its name tells you the salt figure.
What does a low-salt figure mean on a nutrition label?
MyHealth London NHS gives 0–0.3g salt per 100g as its low range. Use the numeric declaration to compare products, and consider how much tomato you will use; a per-100g figure is not the salt amount for an entire recipe.
Should I add salt to sauce made with a lower-salt tin?
Taste the cooked sauce before deciding. The NHS notes that salt already present in ingredients and salt added during cooking both contribute to the finished dish, so consider the other ingredients as well as the tomatoes.
Do chopped and finely chopped tomatoes work the same way in a sauce?
They offer different piece sizes. Napolina describes its chopped tomatoes as chunky and suited to thick sauces, while Mutti’s finely chopped format is an option when smaller pieces are wanted. Choose the texture for the dish, then compare suitable tins by salt per 100g.
What should I do with tomatoes left in an opened tin?
Follow the storage instructions on the exact product you buy and plan how you will use any leftovers. The appropriate instructions can differ between products, so check the pack rather than applying one opened-tin period to every brand.
