For a one-person budget shop, a standard 400g can is a starting point if its labelled servings and ingredients fit the meal you have in mind; 400g does not automatically mean one portion. Campbell's 295g Cream of Chicken Condensed Soup is labelled as two portions, so check its preparation instructions and plan for leftovers before choosing it instead.
Who is choosing soup for one?
One-person cupboard shoppers
If you keep a can for a quick lunch or light dinner, check its labelled portions rather than assuming you will eat it all at once. Campbell's 295g Cream of Chicken Condensed Soup, for example, is labelled as two portions on Ocado.
Vegetarian soup shoppers
M&S provides vegetarian and vegan filters for its tinned-soup range and describes its Cream of Tomato Soup as suitable for vegetarians. Check the current pack when choosing a particular variety.
Shoppers checking salt or allergens
Read the nutrition panel for the amount you expect to eat, and check the exact ingredients when an allergen matters. Flavour names alone cannot establish what a soup contains.
What should you check on the can?
For soup bought for one person, start with the portion you intend to eat, then check preparation, ingredients and the nutrition panel.
| Priority | What to check | Your needs |
| Can size |
Compare the can's weight with the amount you expect to use. Tesco Groceries lists a 400g vegetable soup; Ocado lists Campbell's condensed chicken soup in a 295g can. |
A smaller can appeals to me if I do not plan to use a full 400g can, but its weight alone will not tell me how many servings it contains. |
| Servings |
Read the labelled serving count and opened-can storage directions. Ocado lists two 147.5g portions for Campbell's 295g Cream of Chicken Condensed Soup. |
If I want just one meal, I need to know whether I will have soup left to store. |
| Preparation |
Check whether the soup needs diluting and what the instructions ask you to add. Follow the directions for the exact variety. |
I want to know what preparing the can involves, especially if I am choosing between standard and condensed soup. |
| Ingredients |
Read the current ingredients and allergen information; use vegetarian or vegan filters to narrow a range, not to identify every suitable can. |
When an ingredient matters to me, I check the particular soup rather than relying on a vegetable or tomato flavour name. |
| Salt |
Compare salt per serving and per 100g, then account for the amount you intend to eat. Ocado lists 1.27g salt per 147.5g serving of Campbell's condensed chicken soup. |
If I eat more than the labelled serving, I need to assess the salt for that larger amount, not just the figure for one serving. |
Common mistakes to avoid
-
Assuming one can means one serving
A can can contain multiple labelled portions. Ocado lists Campbell's 295g Cream of Chicken Condensed Soup as two portions, so opening it for one meal may leave soup to store.
Check the serving statement before buying. For that Campbell's soup, Ocado advises moving unused soup to a suitable covered container, refrigerating it and using it within two days.
-
Judging dietary suitability by the flavour
A tomato or vegetable name does not establish whether a particular recipe meets a dietary requirement.
Check the current ingredients and allergen information on the exact soup, even if a retailer's dietary filter helped you find it.
-
Reading salt for one serving but eating more
The nutrition panel's serving figure may cover less than the amount you put in your bowl.
Compare the labelled serving size with the amount you plan to eat. The NHS advises checking food labels when comparing salt content.
Brand and range references
These examples show different formats and shopping checks; a brand name alone does not establish the right portion or ingredients for a particular meal.
Tesco
Tesco Groceries lists a 400g Tesco Vegetable Soup alongside a 400g Stockwell & Co vegetable soup.
- The listed 400g cans provide standard-size examples to compare by serving guidance and ingredients.
- Check the exact can's label: its weight does not establish that it is one serving.
Heinz
Tesco Groceries lists Heinz Vegetable Soup in a 400g can.
- A named vegetable variety offers a specific flavour to consider alongside other 400g cans.
- Check the selected variety's serving statement and ingredients rather than applying another Heinz soup's details to it.
Campbell's
Ocado lists Campbell's Cream of Chicken Condensed Soup as a 295g can containing two labelled portions.
- The labelled portions make it possible to plan whether to use the can across meals.
- Check the dilution instructions and plan to refrigerate any unused soup as directed on the pack.
M&S
M&S offers vegetarian and vegan filters in its tinned-soup range and labels its 400g Cream of Tomato Soup as suitable for vegetarians.
- The filters help narrow the range before checking an individual soup.
- M&S asks shoppers to select a local Foodhall to see stock; read the current product label for ingredients.

Frequently asked questions
Is a 400g can always one serving?
No. Check the serving statement rather than treating can weight as a portion size. Ocado lists Campbell's 295g Cream of Chicken Condensed Soup as two 147.5g portions, showing why the label matters even with a smaller can.
Can I keep tinned soup after opening it?
Follow the directions for the particular soup. Ocado says unused Campbell's Cream of Chicken Condensed Soup should be put in a suitable covered container, refrigerated and used within two days; M&S also gives a two-day refrigerated-storage direction for its Cream of Tomato Soup.
How do I check a soup's allergens?
Read the current ingredients and allergen information for the exact variety, rather than judging it by the flavour name. Recheck the pack when you buy it, particularly if you must avoid a specific ingredient.
Which salt figure matters if I eat the whole can?
Use the serving size and salt figure together to assess the amount you actually plan to eat. Ocado lists 1.27g salt per 147.5g serving for Campbell's 295g condensed chicken soup, which it labels as two portions; the NHS advises checking food labels when comparing salt content.
