Couples planning a quick holiday lunch
A ready-to-heat 400g tin can be divided into two half-can portions where the label uses that serving size. Consider what else you will serve if each person wants more than a light bowl of soup.
Who is each option for?
Self-catering cooks
Condensed soup is worth considering when you have cooking facilities and want to use the tin in a sauce, bake or casserole as well as in bowls.
Pairs checking dietary requirements
Anyone avoiding particular allergens or animal-derived ingredients needs to read the exact tin. Tomato and vegetable flavour names do not establish whether a soup contains milk or celery, or whether it is vegan.
What should you check before buying?
Decide whether the tin is for two bowls or for cooking, then compare portions, ingredients and storage instructions on the products you are considering.
Ready-to-heat soup
Choose it when: You want to heat and divide a tin into two light portions; Tesco's 400g tomato soup labels half a can as 200g.
Bear in mind: The Tesco and Heinz tomato soups described here contain milk, so the flavour alone cannot establish dietary suitability.
Condensed soup
Choose it when: You want a soup that can also be used as a cooking ingredient; Campbell's describes this use for its condensed Cream of Tomato.
Bear in mind: Campbell's 295g tin states nutrition for a 147.5g portion, rather than the 200g half-can portion on the Tesco ready-to-heat tin.
Vegan-labelled soup
Choose it when: Vegan suitability is required; look for a clear claim on the exact product rather than relying on a vegetable flavour.
Bear in mind: Check the ingredients and allergen declaration as well as the dietary label, particularly if product information appears inconsistent.
| Priority | What to check | Your needs |
|---|---|---|
| Portions and format | Read the tin weight and declared serving size. Check whether it is ready to heat or condensed, and how you plan to prepare it. | I want to know whether one tin will make two suitable bowls, or whether I should plan another dish. |
| Salt | Compare salt per 100g, then check the amount in the portion each person will eat. The NHS notes that labels may also give nutrition per portion. | If salt matters to our choice, I want to compare the same quantity of soup before looking at different suggested serving sizes. |
| Ingredients | Read the exact ingredients and allergen declaration. Heinz Cream of Tomato lists milk; Campbell's condensed Cream of Tomato lists milk and celery. | One of us may need to avoid an ingredient or choose a vegan product, so a flavour name is not enough. |
| After opening | Check the product's refrigeration, container and use-by instructions after opening. Tesco says to move leftovers to a non-metallic container and consume them within four days. | With limited fridge space on holiday, I need to know whether we can finish the tin or store what remains as directed. |
Common buying mistakes
-
Assuming every tin makes the same two portions
Tesco's 400g ready-to-heat tomato soup defines half a can as 200g. Campbell's 295g condensed Cream of Tomato uses a 147.5g portion basis and can also be used in cooking.
Check the serving basis against the meal you intend to make, rather than dividing tins by count alone.
-
Comparing salt using different serving sizes
A smaller stated portion can show less salt per serving without telling you how two full bowls compare. In its 2026 analysis of 481 chilled and ambient soups, Action on Salt reported suggested serving sizes ranging from 147.5g to 500g.
Compare salt per 100g first, then read or calculate the amount for the portion each person will actually have.
-
Judging allergens or vegan suitability by flavour
The Heinz tomato soup described by ASDA contains milk, while Campbell's Cream of Tomato lists milk and celery. M&S also distinguishes vegan from vegetarian products in its soup range.
Read the ingredients and allergen declaration on the exact tin; where vegan suitability matters, check its dietary labelling too.
-
Applying one storage rule to every opened tin
Open-life instructions differ: Tesco specifies up to four days for its Cream of Tomato after transfer and refrigeration, while the Joybuy listing for Heinz Cream of Tomato says to refrigerate unused soup in a suitable container and eat it within two days.
Follow the instructions on the tin you have. GOV.UK says to follow packaging directions to refrigerate food after opening.
Relevant brand references
These examples show differences between specific soups and ranges; check the individual tin before applying a detail to another flavour.
Heinz
The checked Cream of Tomato is a 400g ready-to-heat soup with nutrition stated per half can.
- Its product information identifies it as suitable for vegetarians.
- It contains milk; the ASDA listing states 1.1g salt per half can.
Campbell's
Campbell's describes its condensed Cream of Tomato as an option for use in recipes as well as soup.
- The checked 295g product gives nutrition for a 147.5g portion.
- Its ingredients include milk and celery, and Campbell's lists 1.34g salt per stated portion.
Tesco
Tesco Cream of Tomato is a 400g ready-to-heat soup with a labelled 200g half-can portion.
- Its product information gives both microwave and hob instructions.
- It contains milk. For leftovers, Tesco instructs shoppers to use a covered, non-metallic container in the fridge and consume them within four days.
M&S
The M&S tinned-soup range includes vegetable, minestrone and meat-containing choices, with separate vegan and vegetarian filters.
- The range offers different flavours and dietary filters to explore.
- A range filter does not establish the ingredients, allergens or storage instructions for every tin; check the chosen product.
Joybuy soup options
These 400g bean, pea and vegetable soups offer alternatives to smooth tomato soup for a shared holiday meal. Check each tin's serving and preparation instructions before planning two bowls.

Suma Organic Tuscan Bean Soup 400g
A bean soup to consider when two diners want a non-tomato flavour. Check the portions and heating directions for your meal; the product information flags celery and says to refrigerate leftovers and use them within two days.
No image available
Suma Pea & Vegan Ham Soup 400g
This pea soup is another 400g option for a shared meal, but check its portions and preparation directions. The supplied product information makes a vegan-friendly claim while also listing milk, so confirm suitability on the packaging rather than relying on the name; it also lists soy and wheat allergens.

Baxters Vegetarian Country Garden Soup 400g
A vegetable-and-rice soup to consider instead of tomato. Check the intended portions and heating directions for two; its product information flags milk and says to refrigerate opened soup for up to two days.
Questions about soup for two
Is one 400g tin enough for two people?
A tin labelled as two 200g half-can portions can make two light bowls, but whether that is enough for lunch depends on what else you serve. Check the particular soup's serving size: Campbell's condensed Cream of Tomato, for example, uses a different 147.5g portion basis.
How can I compare salt between tins?
Compare the salt figures per 100g, then check how much salt is in the portion you intend to serve. The NHS explains that nutrition labels give figures per 100g or 100ml and may also give them per portion, so two different suggested portions need not represent the same amount of soup.
Is tomato or vegetable tinned soup necessarily vegan?
No. The checked Heinz tomato soup contains milk, and Campbell's condensed tomato soup lists milk and celery. Look for vegan labelling on the exact product and read its ingredients and allergen declaration.
What should I do with soup left in an opened tin?
Follow that product's instructions for the container, refrigeration and how soon to use it. Tesco specifies a covered, non-metallic container and four days for its Cream of Tomato; the checked Joybuy Heinz listing specifies a suitable refrigerated container and two days. GOV.UK advises following post-opening refrigeration instructions on packaging.
Does passing the best-before date automatically make a tin unsafe?
No: GOV.UK distinguishes a best-before date, which concerns quality, from a use-by date, which concerns safety. Check the date wording and storage instructions on the particular tin; its quality may decline after a best-before date.
