Households planning quick lunches
Ready-to-heat tins offer a straightforward cupboard meal. Check how much soup you expect to serve, rather than assuming that tins of the same weight make equivalent portions.
Who is this for?
Weekly shoppers planning portions
Compare pack sizes and the number of servings you will use. A smaller condensed tin intended for cooking serves a different purpose from a ready-to-heat tin.
Shoppers with dietary requirements
Check the ingredients and highlighted allergens on each current label. The illustrated cream-of-tomato products include milk; Campbell’s condensed tomato soup also lists celery.
What should you check?
Decide whether the soup is for a quick bowl or a recipe, then compare labels using both the stated serving and a consistent per-100g basis.
| Priority | What to check | Your needs |
|---|---|---|
| Soup format | Check whether the tin is ready to heat or condensed. For condensed soup, read the preparation directions and the basis used for its serving figures. | I want a quick bowl without preparation beyond heating, or a soup I can also use in cooking. |
| Salt and sugars | Compare salt and total sugars per 100g and for the portion you plan to eat. Read the serving size before comparing a standard tin with a no-added-sugar variant or prepared condensed soup. | If soup is a regular lunch, I want to know what my actual portion contains. A no-added-sugar label does not mean the soup contains no sugars. |
| Allergens and diet | Read the current ingredients and highlighted allergens. Check vegetarian or vegan suitability separately: a vegetarian cream soup may still contain milk. | Milk or celery could affect which recipe I can use, even when two tins look similar. |
| Pack and leftovers | Check the tin weight against the number of portions you expect. Follow the particular product’s instructions for transferring, refrigerating and using opened soup. | I would rather choose a quantity my household can finish within the tin’s stated period after opening. |
Common buying mistakes
-
Treating all tomato-soup tins as interchangeable
Ready-to-heat and condensed soups have different uses, and a condensed soup’s nutrition may be stated for a prepared portion.
Choose the format for the meal you have in mind, then compare the preparation directions and nutrition figures on the same basis.
-
Stopping at the front-of-pack wording
“No added sugar” does not mean sugar-free, while vegetarian suitability does not establish that a cream soup is milk-free. Recipes can also have different allergens.
Read total sugars, salt, serving size and highlighted allergens on the exact tin. GOV.UK explains that traffic-light labels indicate levels of fat, saturated fat, sugars and salt; use them alongside the full nutrition panel.
-
Overlooking instructions after opening
Use periods differ between products: the ASDA cream-of-tomato example says four days after opening, while the illustrated Heinz and M&S products say two days.
Plan portions before opening a tin, transfer leftovers as directed, refrigerate them and follow that product’s stated period.
Brand and retailer examples
These examples show how tomato-soup recipes and formats can differ; check the current label for the particular tin you choose.
Heinz
Heinz has a ready-to-heat 400g Cream of Tomato Soup and a separate No Added Sugar variant.
- The standard product’s listed half-can serving contains 1.1g salt; the No Added Sugar variant lists 0.8g salt per half can.
- Both illustrated variants contain milk. The No Added Sugar variant also lists naturally occurring sugars.
Campbell’s
Campbell’s describes its 295g condensed Cream of Tomato Soup as a soup that can also be used as a cooking base.
- Its labelled nutrition gives a 147.5g portion as consumed, making the preparation basis important when comparing it with ready-to-heat soup.

Asda
ASDA’s own-label Cream of Tomato Soup is a 400g vegetarian option.

Frequently asked questions
Should I compare tinned soup per serving or per 100g?
Use both: per 100g helps you compare different tins on a consistent basis, while the serving figure shows the amount in the portion stated on that product. Check the preparation basis for condensed soup before comparing it with a ready-to-heat tin.
Does no added sugar mean tomato soup contains no sugars?
No. ASDA’s listing for Heinz No Added Sugar Cream of Tomato Soup gives 5.3g total sugars per half can and notes naturally occurring sugars. Read the total sugars line on the current label.
Are cream-of-tomato soups suitable for a milk or celery allergy?
Do not assume they are. The illustrated Heinz, ASDA and M&S cream-of-tomato products contain milk, while Campbell’s condensed tomato soup lists both milk and celery. Check the ingredients and highlighted allergens on the exact tin.
What should I do with soup left after opening a tin?
Follow that tin’s transfer, refrigeration and use instructions. ASDA says to use its illustrated cream-of-tomato soup within four days after opening; the illustrated Heinz and M&S products specify two days.
Can I recycle an empty soup tin?
Recycle Now advises emptying and rinsing food tins and putting tin lids inside; labels can stay on. Check your local collection arrangements if you are unsure what is accepted.
