A 400g tin can work well for one person if you will eat the second portion and can store it as the label directs: the Tesco, Sainsbury’s and Asda examples here each state two servings. If you would rather avoid leftovers, compare cup or sachet soup, checking its prepared serving size. For any format, compare salt for the amount you will actually eat, check allergens and distinguish ready-to-heat soup from condensed soup that needs diluting.
A 400g tin can fit a one-person routine when you have a plan for the remainder. The Tesco, Sainsbury’s and Asda tomato soups cited here each label a 400g pack as two servings; follow the storage directions on the tin you choose.
Compare the serving yield of a cup or sachet soup with a tin before buying. M&S lists a tomato soup in a cup that is prepared with boiling water, but a cup format is not itself a guarantee of a particular prepared portion size.
Use the nutrition panel for the portion you expect to eat, and read the ingredient and allergen information for the exact recipe. The cited soups differ in their salt figures and include recipes listing milk, mustard or celery.
Start with the amount you will prepare and eat, then check the label details that change whether that format works for one person.
Choose when: You can use a second portion if the tin is labelled as two servings.
Bear in mind: The remainder needs storing and using according to that tin’s instructions.
Choose when: Avoiding an opened half-tin matters more than choosing a tinned format.
Bear in mind: Check the prepared serving size and nutrition basis rather than comparing pack weights alone.
Choose when: You want soup to use in cooking or are happy to dilute it before heating.
Bear in mind: Preparation adds a step, and the nutrition panel may use an ‘as consumed’ basis.
| Priority | What to check | Your needs |
|---|---|---|
| Portion size | Compare the pack weight with its stated number of servings. Check what the nutrition panel calls one serving. | I want one meal, not a second portion to plan around. Tesco, Sainsbury’s and Asda each describe their cited 400g tomato soup as two servings. |
| Leftovers | Read the after-opening container, refrigeration and use-within directions on the exact pack. | If I save half a tin, I need to know when I will eat it. Sainsbury’s Tomato & Basil Soup directs shoppers to transfer leftovers to a non-metallic container, refrigerate them and use them within two days. |
| Salt | Compare grams of salt for the same amount of soup, then work out the amount in the portion you will eat. For a whole tin labelled in half-tin servings, account for both halves. | I may eat the whole tin, so a half-tin figure alone will not describe my meal. Tesco lists 0.69g salt per 200g half-can and Asda lists 0.94g per half-can for the cited products. The NHS advises adults to have no more than 6g of salt a day. |
| Ingredients | Check the current ingredient and highlighted allergen information for the exact flavour, not just the brand or soup type. | Milk, mustard or celery could rule out a recipe for me. Asda’s cited tomato soup lists milk and mustard; Campbell’s condensed tomato soup lists milk and celery. |
| Preparation | Check whether the soup is ready to heat, needs boiling water or requires dilution. For condensed soup, check whether nutrition is stated for the concentrate or as consumed. | Some days I want to heat a bowl; other times I can prepare a cooking ingredient. Campbell’s condensed chicken soup instructions specify adding one can of water, or half milk and half water, before heating. |
The cited Tesco, Sainsbury’s and Asda tomato soups each describe a 400g pack as two servings. Eating the whole tin means using twice a half-tin nutrition figure.
Check the serving count alongside the pack weight. If you do not want a second portion, compare the prepared serving yield of a cup or sachet soup.
A per-100g figure, a half-tin figure and an ‘as consumed’ figure do not describe the same amount of soup. A whole 400g tin also contains more salt than its labelled 200g serving.
Use the nutrition panel to calculate grams of salt for the amount you expect to eat, keeping the preparation basis consistent when comparing products.
Saving a second serving is only practical if you can follow that product’s after-opening instructions. Sainsbury’s Tomato & Basil Soup specifies a non-metallic container, refrigeration and use within two days.
Read the exact pack before opening it and plan when you will use any remainder.
Condensed soup can require dilution. The cited Campbell’s chicken soup instructions call for one can of water, or half milk and half water, before heating.
Choose a ready-to-heat format when you do not want that preparation step; choose condensed soup when its cooking use and instructions suit your plans.
These examples show why the exact recipe and format matter more than a brand name alone.

Not in every case: the cited Tesco, Sainsbury’s and Asda 400g tomato soups each state two servings. Check the serving count on your tin; if you eat all of a tin labelled in half-tin servings, account for both halves when reading its nutrition information.
Follow the directions on that product. Sainsbury’s Tomato & Basil Soup says to transfer leftovers to a non-metallic container, refrigerate them and use them within two days; the cited Heinz Cream of Tomato listing also directs shoppers to refrigerate unused soup and consume it within two days.
Use the amount of salt in the whole portion you eat, rather than a half-tin figure alone. If a 400g tin lists salt per 200g half-can, both halves contribute to your meal; the NHS advises adults to have no more than 6g of salt a day.
No. The cited Tesco and Asda tomato soups list milk ingredients, and Campbell’s condensed tomato soup lists milk and celery. Check the ingredient and allergen information for the exact flavour and current pack.
Condensed soup needs the preparation specified on its label before heating: the cited Campbell’s condensed chicken soup calls for one can of water, or half milk and half water. If you want a simpler bowl, check for a ready-to-heat product instead; for condensed soup, also check the basis used for its nutrition figures.
