Who is this choice for?

For a late-night supper, the useful distinction is not just flavour: consider what is in the bowl, how much of the tin you will eat and what happens to the rest.

Solo diners using cupboard staples

A tin can provide a supper when fresh ingredients are limited. If you will eat only part of it, choose a size and recipe whose after-opening instructions fit your plans; the checked Tesco, Sainsbury’s, M&S and Heinz products specify refrigeration and differing use periods.

Vegetarian or vegan shoppers

Check the exact recipe rather than relying on the soup’s name. Sainsbury’s checked cream-of-tomato soup is labelled vegetarian and contains milk; the checked M&S Minestrone is labelled vegan and contains pasta, beans and vegetables, but lists allergens of its own.

Shoppers comparing salt

Read the salt value for the portion you expect to eat, as well as the per-100 g figure. The checked tomato soups list different amounts per half-can, so the flavour alone does not tell you the salt content.

What should you check?

Start with the recipe and serving size, then check the label details that could change whether the tin works for your supper.

PriorityWhat to checkYour needs
Preparation Read the pack’s heating directions and unopened storage instructions. Check whether you have the equipment and time needed to prepare it. I want something I can keep in the cupboard and heat when I get home late.
Recipe and texture Look for beans, pasta or vegetables if you want them in the soup; compare protein and fibre per 100 g if those figures matter to you. The checked M&S Minestrone contains pasta, borlotti beans and vegetables, while the checked Tesco and Sainsbury’s cream-of-tomato soups are smooth recipes. A smooth bowl with a side would suit me, or I would rather have identifiable ingredients in the tin. Texture and nutrition figures do not guarantee how filling a portion will feel.
Salt and portion Compare both salt per 100 g and salt for the amount you will eat. The checked half-can servings list 0.89 g for Sainsbury’s Cream of Tomato, 1.12 g for Tesco Cream of Tomato and 1.1 g for Heinz Cream of Tomato in Asda’s listing. NHS guidance says adults should have no more than 6 g of salt a day. If soup is my supper, I want to know what my actual portion contributes, especially if I am also having bread, cheese or another side.
Allergens and dietary labels Read the current ingredients and allergen information for the exact soup. The checked cream-of-tomato recipes contain milk; M&S lists its vegan Minestrone as containing wheat/gluten and celery and as unsuitable for people with milk or egg allergy. Vegetarian or vegan wording matters to me, but I also need to check separately for ingredients that I cannot eat.
Leftovers Check the serving count and after-opening instructions. Tesco says to transfer, cover and refrigerate unused cream-of-tomato soup and consume it within 4 days; Sainsbury’s specifies a non-metallic lidded container and 2 days. Follow your particular pack. Will I finish this tin tonight, or can I refrigerate the remainder and use it within the time on its label?

Common buying mistakes

  • Assuming a 400 g tin is one portion

    The checked 400 g tomato soups give nutrition information for half-can servings. Eating the whole tin changes the amount of salt and other nutrients in your meal; saving half means following the after-opening instructions.

    Check the serving size against how much you will eat, and choose a tin you can finish or store as directed.

  • Assuming tomato soup is low in salt

    Salt differs between the checked cream-of-tomato products even when the comparison is a half-can serving. NHS guidance says the adult daily maximum is 6 g, including salt already in food and salt added later.

    Compare the exact cans per serving and per 100 g, including the portion you plan to eat and any sides.

  • Using the flavour name as an allergen check

    The checked creamy tomato recipes contain milk. The checked M&S vegan Minestrone contains wheat/gluten and celery and carries further allergy suitability information.

    Read the current pack’s ingredients, allergens and dietary declaration for the exact recipe, including one you have bought before.

  • Letting a front-of-pack claim settle the whole choice

    A fruit-and-vegetable or dietary claim does not tell you the soup’s salt per portion, all its ingredients or how to keep an opened tin.

    Use the claim to identify a possible option, then read the serving, nutrition, allergen and storage information before choosing.

Brand and retailer references

These examples illustrate label differences on particular UK products and ranges; the details should not be applied to every soup carrying the same brand or retailer name.

Heinz

Heinz Cream of Tomato Soup 400 g is a smooth tomato example with a manufacturer ingredient list and an Asda listing for portion and storage details.

  • Heinz lists tomatoes as 89% of this recipe’s ingredients.
  • The recipe contains milk. Asda lists 1.1 g salt per half-can and says to refrigerate unused soup and eat it within 2 days.

Tesco

Tesco Cream of Tomato Soup 400 g is a supermarket own-label example for comparing portions and opened-can storage.

  • The checked tin provides half-can serving information.
  • Tesco lists 1.12 g salt per half-can and instructs shoppers to transfer unused soup to a covered, non-metallic container, refrigerate it and consume it within 4 days.

Sainsbury’s

Sainsbury’s Cream of Tomato Soup 400 g offers another vegetarian, smooth-soup example with half-can label information.

  • The checked product lists 0.89 g salt per half-can.
  • It contains milk. Sainsbury’s says to transfer unused soup to a non-metallic lidded container, refrigerate it and use it within 2 days.

Asda’s checked listing is for Heinz Cream of Tomato Soup 400 g, rather than an Asda own-label tomato soup.

  • The listing provides product-specific salt, milk-allergen and after-opening information for that Heinz tin.
  • Those details describe the listed Heinz product, not Asda’s own-label range.

M&S

The M&S tinned-soup range includes smooth and chunky styles. Its checked Minestrone Soup 400 g provides a bean-and-pasta example.

  • M&S labels this Minestrone vegan and vegetarian and lists 2.1 g protein and 1.6 g fibre per 100 g.
  • It contains wheat/gluten and celery; M&S also states that it is not suitable for people with milk or egg allergy. The product says to refrigerate opened soup in an airtight container and eat it within 2 days.

Frequently asked questions

Should I choose smooth tomato or chunky soup for a late-night supper?

Choose smooth tomato soup if you want that texture and are happy to add a side; choose a chunky bean-and-pasta soup if you want those ingredients in the tin. For a concrete comparison, M&S lists 2.1 g protein and 1.6 g fibre per 100 g for its checked Minestrone. Recipe and nutrition differences do not guarantee that one portion will feel more filling.

How should I store soup left in an opened tin?

Follow the exact product’s after-opening directions. Tesco says to transfer unused Cream of Tomato soup to a covered non-metallic container, refrigerate it and consume it within 4 days; Sainsbury’s specifies a non-metallic lidded container and use within 2 days. GOV.UK advises keeping a fridge between 0°C and 5°C and generally eating leftovers within two days or freezing them if that will not be possible.

What is the useful way to compare salt in tinned soup?

Check salt per 100 g for a like-for-like label comparison, then salt for the amount you intend to eat. The checked Sainsbury’s, Heinz and Tesco cream-of-tomato soups list 0.89 g, 1.1 g and 1.12 g respectively per half-can, according to their product information. NHS guidance says adults should have no more than 6 g of salt a day, including salt already in food.

Does the flavour tell me whether a soup is vegan or free from allergens?

No. The checked Tesco, Sainsbury’s and Heinz cream-of-tomato recipes contain milk. M&S labels its checked Minestrone vegan, but lists wheat/gluten and celery and says it is not suitable for people with milk or egg allergy. Check the current pack’s dietary declaration and allergen information for the exact recipe.
