Weekly-shop cupboard-meal planners
A single ready-to-heat tin gives you a lunch or light-meal option without buying a multipack. Check how many servings the label assigns to the tin, particularly if you expect to eat it all at once.
Who is a single tin for?
Shoppers comparing salt
If salt is an important part of your choice, compare the amount for the portion you will actually eat. A claim about less salt than another recipe is not a substitute for the figure on the current can.
Flexible cooks and ingredient-checkers
A condensed tin may work as a soup or a cooking ingredient, provided its preparation suits your plans. For dietary exclusions, check the exact ingredients and allergens: a tomato or vegetable-based name does not establish that a soup is dairy-free.
What should you check before buying?
Start with how you intend to use the tin, then compare portions, ingredients and instructions for the recipes you are considering.
| Priority | What to check | Your needs |
|---|---|---|
| Preparation format | Check whether the tin is ready to heat or condensed. For condensed soup, read how to prepare it and what the recipe will require. | I want a straightforward cupboard lunch, or I want a soup I can also use as a cooking ingredient. |
| Portion and salt | Check the labelled serving size and salt per serving or per 100g, then relate the figure to the amount you will eat. Sainsbury's lists 1.1g salt per half-can for Heinz Cream of Tomato Soup 400g. The NHS advises adults to have no more than 6g of salt a day. | If I eat the whole tin, a half-can nutrition figure will not describe my whole meal. I want to compare recipes on the same portion basis. |
| Recipe and allergens | Read the exact can's ingredients and allergen statement. Sainsbury's lists milk ingredients in Heinz Cream of Tomato Soup 400g; recipes can differ between tins. | I may prefer a soup with pulses rather than a smooth tomato recipe, or need to avoid particular ingredients. A recipe name alone will not settle that choice. |
| Leftovers | Check the instructions for storing soup after opening, especially if the tin covers more than one meal. Follow the timing and container directions for that product. | When I split a tin between meals, I need a plan for the unused soup before opening it. |
Mistakes to avoid
-
Reading a half-can figure as a whole-tin figure
Sainsbury's lists 1.1g salt per half-can for Heinz Cream of Tomato Soup 400g. Eating the full tin means eating two of those labelled portions.
Decide how much soup you expect to eat, then compare the nutrition figures on that basis.
-
Assuming tomato soup has no dairy ingredients
The Heinz Cream of Tomato Soup 400g ingredient list at Sainsbury's includes dried skimmed milk, cream and milk proteins.
Check the current can's ingredients and allergen statement when buying for an allergy, intolerance or vegan diet.
-
Choosing condensed soup for a ready-to-heat lunch
Condensed soup needs preparation, so the tin's contents are not directly comparable with a ready-to-heat serving.
Read the preparation directions before choosing it for lunch; consider a ready-to-heat tin if minimal preparation is the priority.
-
Overlooking leftovers and the empty tin
Storage directions matter when you do not eat the whole tin. Food left in the finished tin also needs removing before recycling.
Follow the product's instructions for unused soup. Recycle Now advises emptying and rinsing food tins, then checking local collection arrangements.
Brand and own-label references
These examples show how recipe and format vary; a brand name does not establish the ingredients or suitability of every soup in its range.
Heinz
Its Cream of Tomato Soup is listed as a 400g tin. Heinz also makes a no-added-sugar Cream of Tomato variant.
- Sainsbury's lists ingredients and nutrition per half-can for the standard Cream of Tomato Soup.
- Heinz describes the no-added-sugar variant as having 25% less salt than its standard Cream of Tomato Soup. That named-product comparison does not replace checking the current salt figure and allergens.
Sainsbury's
Its listed 400g tins include Cream of Tomato Soup and a Tomato & Three Bean recipe with red lentils.
- The recipe choice lets shoppers compare a smooth tomato soup with one containing pulses.
- Check each recipe's ingredients, allergens and nutrition separately; the own-label name does not establish dietary suitability.
Tesco
Tesco lists an own-label Cream of Tomato Soup in a 400g tin.
- It is an own-label single-tin cream-of-tomato option to consider alongside branded recipes.
- Tesco cautions that ingredients, nutrition and allergens may change as products are reformulated, so read the physical label.
M&S
M&S describes its Cream of Tomato Soup as made with tomatoes and British double cream.
- The stated recipe gives shoppers a specific creamy tomato option to assess.
- Double cream matters if you avoid dairy; suitability claims for this soup do not apply to the whole M&S range.
Campbell's
Campbell's Condensed Cream of Tomato Soup is listed as a 295g tin that can be prepared as soup or used in cooking.
- The condensed format offers a different use from a ready-to-heat tin.
- Check its preparation instructions, ingredients and resulting serving before comparing it with a ready-to-heat soup.

Common questions
Is one 400g tin of soup one serving?
Not necessarily. Sainsbury's gives nutrition per half-can for Heinz Cream of Tomato Soup 400g. Use the portion stated on the exact can to work out the figures for the amount you intend to eat.
How should I compare salt between tins?
Compare salt for equivalent amounts, such as the portion you intend to eat, rather than comparing a half-can figure with a whole tin. The NHS advises adults to have no more than 6g of salt a day; check the current nutrition panel even when a product claims less salt than a named alternative.
Can I assume cream-of-tomato soup is free from milk?
No. Sainsbury's lists dried skimmed milk, cream and milk proteins in Heinz Cream of Tomato Soup 400g. Check the ingredients and allergen statement on the specific tin you buy.
What should I do with soup left after opening a tin?
Follow that product's storage directions. For its Heinz No Added Sugar Cream of Tomato Soup 400g listing, Sainsbury's instructs shoppers to put unused soup in a suitable container in the fridge and eat it within two days.
Can I recycle an empty soup tin?
Recycle Now advises emptying and rinsing food tins, placing lids inside and leaving labels on. Check your local collection arrangements for the appropriate recycling route.
