Solo shoppers planning a cupboard lunch
A tin can be kept unopened as directed on its label until you need it. Check the stated servings and nutrition for the amount you intend to eat, rather than treating pack weight as a portion guide.
Who is this choice for?
Shoppers drawn to speciality recipes
A larger tin may work if you can share it or follow its instructions for storing leftovers. Marks & Spencer lists M&S Collection soups weighing 550g to 580g, so check the individual pack before buying one for a solo meal.
Shoppers checking salt or allergens
Compare the exact product’s nutrition and ingredients, not just its range name or an online filter. The NHS notes that a manufacturer’s stated portion may differ from the amount you eat.
What should you check first?
Decide whether you want soup from the cupboard or a self-contained chilled meal, then check the exact pack’s servings, ingredients and nutrition.
400g tinned soup
Choose it when: You want a cupboard soup and its stated serving size fits your meal.
Bear in mind: The NHS says a manufacturer’s portion can differ from the amount you eat; a 400g weight is not a one-serving claim.
Larger speciality tin
Choose it when: You want a particular recipe and can accommodate the pack’s stated servings.
Bear in mind: Marks & Spencer lists M&S Collection soups at 550g to 580g; check whether you will need to store some after opening.
Chilled meal for one
Choose it when: You want a self-contained meal explicitly labelled as one serving rather than a bowl of soup.
Bear in mind: Check its refrigeration instructions and date label; it is a different choice from a cupboard tin.
| Priority | What to check | Your needs |
|---|---|---|
| Portion size | Read the number of servings and compare nutrition per 100g, per portion and, if given, per pack. The NHS notes that stated portions may differ from what you eat. | I want to know whether the amount I will eat matches the figures on the label, especially if I plan to finish the tin. |
| Recipe | Compare the listed ingredients and recipe style on the exact product. For a larger tin, check its serving guidance before deciding it suits one meal. | A speciality flavour matters to me, but I may prefer a smaller pack if I do not want leftovers. |
| Salt and nutrition | Compare salt and other nutrition values on the same basis, such as per 100g, then consider the amount you expect to eat. Read traffic-light information where present. | If soup is part of my regular lunches or I am adding a side, I want the figures for the whole meal I am planning. |
| Ingredients and allergens | Read the ingredients, allergen declaration and dietary wording on the exact pack. Sainsbury’s advises checking labels rather than relying on its allergy and intolerance filters. | I need to know whether this particular recipe meets my ingredient or dietary requirements. |
| Storage | Check unopened storage, the date label and any after-opening instructions. Plan for leftovers before choosing a larger tin. | Will I eat the whole pack, share it or be able to store the remainder as directed? |
Common buying mistakes
-
Assuming a 400g tin means one serving
Pack weight does not establish the manufacturer’s portion size. The NHS notes that nutrition may be shown per 100g and sometimes per portion, which may not match the amount you eat.
Read the stated servings and use the figures for the amount you intend to have.
-
Expecting a speciality range to come in a smaller pack
Marks & Spencer lists M&S Collection soups weighing 550g to 580g. A recipe you want may therefore leave soup after one meal.
Check the pack’s serving and after-opening instructions before choosing a larger tin for one.
-
Judging salt by the soup’s name or ingredients
A vegetable-based or light-sounding recipe does not tell you its salt value. NHS guidance advises comparing food labels for salt.
Compare salt per 100g and for the amount you expect to eat.
-
Using a category filter in place of the label
Recipes within a range can differ. Sainsbury’s tells shoppers not to rely on its allergy and intolerance filters instead of checking the product label.
Read the exact pack’s ingredients, allergen declaration and suitability wording.
Brands and ranges to compare
These ranges illustrate different soup formats; a brand or premium label alone does not establish the serving size of an individual product.
M&S
Marks & Spencer lists standard tinned soups alongside M&S Collection speciality recipes.
- Its listed Collection recipes include French onion and lobster bisque.
- Listed Collection tins weigh 550g to 580g; check the chosen pack’s servings before treating it as one meal.
Tesco
Tesco Groceries lists 400g tinned options, including a Plant Chef tomato and basil soup.
- Its tinned range gives shoppers different recipes to compare by label.
- Tesco Finest fresh soups listed at 600g are a separate format; check both the product type and servings rather than assuming the range name means a tin for one.
Sainsbury’s
Sainsbury’s tinned-soup category includes a Taste the Difference sub-range and dietary filters.
- The category lets shoppers browse different ranges before examining an individual soup.
- Sainsbury’s advises checking the product label rather than relying on allergy and intolerance filters.
Heinz
Tesco Groceries lists Heinz tinned soups, including 400g classic and Big Soup examples.
- Listed 400g recipes offer a familiar branded format to compare with other tins.
- Check the selected tin’s servings, ingredients and nutrition; its weight does not settle the one-person portion question.
Campbell’s
Tesco Groceries lists Campbell’s condensed cream of mushroom soup in a 295g pack.
- The listed condensed product offers a different soup format from ready-to-heat tins.
- Check its preparation and serving instructions before comparing the pack weight with a ready-to-heat soup.

Baxters Lobster Bisque Chef’s Selection Soup 400g
This 400g bisque states “Serves 1”, making its portion guidance useful when choosing soup for one. The recipe lists lobster, langoustines, cream, white wine and French brandy; declared allergens include crustaceans, milk, sulphites and celery. Nutrition is listed per 100g, and the supplied heating instructions specify the hob, so follow the pack when preparing it.

Suma Organic Tuscan Bean Soup 400g
This 400g bean soup lists beans, tomatoes, vegetables and herbs, and gives cool, dry storage guidance for the unopened pack. Celery is declared as an allergen and nutrition is listed per 100g. Check the tin’s stated servings and heating instructions before planning it as one meal.
Questions about soup for one
Is a 400g tin of soup definitely one serving?
No. Read the servings stated on the exact tin and compare them with the amount you plan to eat. The NHS notes that a manufacturer’s portion may differ from yours.
What should I compare when buying soup for one?
Start with the stated servings and the nutrition for the amount you expect to eat, then check ingredients, allergens and storage instructions. The NHS says nutrition information is provided per 100g or 100ml and sometimes per portion, so check which measure you are using.
Does a premium soup range mean a portion for one?
No. Marks & Spencer lists M&S Collection soups weighing 550g to 580g. Check the chosen tin’s serving guidance and after-opening instructions if you do not plan to finish it at once.
What does a best-before date mean on a tin?
A best-before date concerns quality, not the same date rule as use by. GOV.UK says food, including tinned food, is usually safe after its best-before date but may not be at its best; follow the product’s storage guidance.
What should I do with soup left after opening?
Follow that tin’s after-opening storage and use instructions. Check them before buying a larger pack if you expect to have leftovers, rather than applying its unopened storage guidance to the opened soup.
