Two campers planning a light hot meal
A can explicitly labelled as serving two takes the guesswork out of dividing lunch. Check that the stated portion suits both people, particularly if the soup is the whole meal.
Who is sharing the soup?
Campers with different dietary requirements
Check the exact can before planning to share it. A vegetarian cream-of-tomato soup can contain milk, while a lentil soup labelled suitable for vegans may still carry an allergen cross-contact warning.
Campers comparing salt per portion
Compare the amount each person will actually eat. Tesco Groceries lists 1.12g salt per half-can for its 400g Cream of Tomato Soup; Ocado lists 0.86g per half-can for M&S Spiced Lentil & Tomato Soup.
What should you check before packing it?
Decide how much soup each person needs, then check that the recipe, preparation method and storage instructions work for the trip.
| Priority | What to check | Your needs |
|---|---|---|
| Portions | Look for a stated serving count and compare it with the 400g net weight. Check whether any suggested side needs packing too. | We want a light lunch from one can, or enough food for each of us to make dinner. A label stating two servings makes the split clear, but it does not decide whether the portion is enough for our meal. |
| Preparation | Read the can’s heating instructions. If they call for hob heating, plan for a stove, fuel, a pan and serving equipment. | There is a stove and pan at our campsite; microwave instructions alone will not help us prepare soup there. |
| Salt per portion | Compare salt for the amount each person will eat, using the serving figure where given. If the label shows only a per-100g figure, account for your intended portion. | I want to compare our actual portions rather than choose by brand or flavour. Action on Salt & Sugar’s February 2026 analysis of 481 ready-to-eat soups illustrates variation across that wider UK product category; it does not describe campers’ preferences. |
| Dietary suitability | Read the ingredients, allergen declaration, cross-contact warning and any vegetarian or vegan statement on the exact can. | Both of us need to be able to eat the same soup. A vegetarian label alone will not tell me whether it contains milk. |
| Leftovers | Check the after-opening instructions and whether you can keep unused soup chilled. The Food Standards Agency’s camping guidance says chilled food should be stored below 5°C. | We would rather finish the can together than plan to save a portion without reliable chilling. |
What can go wrong at the campsite?

Assuming a 400g can makes a full dinner for two
Labels that divide a can into two servings mean 200g of soup per person. That may fit a light meal without being the amount both campers want for dinner.
Check the serving count and your meal plan. Add bread or crackers, or take two cans if each person wants more soup.
-
Choosing by flavour without comparing portions
Salt figures differ between recipes, and a per-100g figure describes less soup than a 200g half-can serving.
Compare labels on the basis of the portion each person plans to eat.
-
Planning to keep leftovers without reliable chilling
Once opened, soup needs to be handled according to its storage instructions. The Food Standards Agency’s camping guidance says chilled food should be stored below 5°C.
Plan to finish the can together, or arrange suitable chilled storage and a container for any unused soup.
Without suitable chilling, unused soup may need to be discarded.
-
Overlooking damage to a tin
A damaged seal or visibly bulging, leaking or rusty can is a food-safety concern, not ordinary camping wear.
Inspect tins before departure and do not eat the contents of a suspect can. The Food Standards Agency’s guidance notes that how long canned food remains acceptable depends on the product, storage conditions and brand.
Brand and product references
These product examples illustrate label differences; a brand name alone does not establish portion size, ingredients or suitability.
Heinz
Heinz Cream of Tomato is a 400g cream-of-tomato example with nutrition given per half-can.
- Tesco Groceries labels the checked product vegetarian.
- Joybuy’s product information lists milk and 1.1g salt per half-can; check the exact tin if either matters to you.
Tesco
Tesco Cream of Tomato Soup is a 400g own-label example with nutrition stated for half a can.
- Tesco Groceries labels the checked soup vegetarian.
- Tesco Groceries lists 1.12g salt per half-can. Check the current pack’s ingredients and allergen statement before sharing it.
Sainsbury's
Sainsbury's Tomato & Spicy Lentil Soup is a 400g example whose label states that it serves two.
- The stated serving count helps two campers plan to split one can.
- It contains celery and chilli; check that the exact recipe suits both people.
M&S
Two checked M&S 400g soups state two servings, but their recipes have different dietary considerations.
- Ocado labels M&S Spiced Lentil & Tomato Soup suitable for vegans and lists 0.86g salt per half-can.
- The spiced lentil recipe has a milk and egg cross-contact warning. M&S Cream of Tomato Soup is vegetarian but contains milk.
Joybuy tinned soup options
These 400g canned soups offer beef-and-vegetable, broth, bean and vegetarian vegetable recipes to consider for a camping meal. Check each can’s serving and preparation instructions before relying on it for two people.

Heinz Big Soup Beef & Vegetable 400g
A beef-and-vegetable soup to consider when sharing one can. Its product information states two servings and gives pan-heating instructions; check that the portion suits both campers and compare salt for the amount each will eat. It contains beef, so it is not a vegetarian option.
No image available
Baxters Favourite Scotch Broth 400g
This broth contains barley, vegetables, mutton and beef, with saucepan heating specified in its product information. Check the pack’s serving guidance before splitting the 400g can, and plan chilled storage if you expect leftovers.
No image available
Suma Organic Tuscan Bean Soup 400g
A bean-and-vegetable option if that recipe appeals to both campers. Check the pack for servings, campsite preparation instructions and salt for your intended portions; its listed ingredients include celery.
No image available
Baxters Vegetarian Country Garden Soup 400g
This vegetarian-labelled vegetable-and-rice soup is another 400g option to consider for sharing. Check the serving and heating instructions on the pack before the trip. It contains milk, so the vegetarian name does not make it suitable for a dairy-free meal.
Questions about camping with tinned soup
Will one 400g can feed two campers?
It can provide two portions when the label says it serves two, as the checked Sainsbury's and M&S examples do. That means 200g each; decide whether that suits a light meal or whether to pack a side or another can.
Can I heat soup in its tin over a camping stove?
Do not assume the tin is intended for direct heating. The checked product instructions describe emptying soup into a saucepan for hob heating, so pack a pan and follow the instructions on your can.
What should I do with soup left after opening?
Follow the can’s after-opening storage instructions and use a suitable container for leftovers. The Food Standards Agency’s camping guidance says chilled food should be kept below 5°C; if you cannot maintain suitable chilling, plan to finish the can rather than save it.
Should I pack a dented or bulging can?
Do not use a visibly bulging, leaking or rusty can, or one with a deep dent that could affect its seal. Inspect tins before leaving; the Food Standards Agency notes that how long canned food remains acceptable depends on the product and its storage conditions.
Are tomato and lentil soups necessarily vegan?
No. Checked cream-of-tomato recipes contain milk despite being labelled vegetarian. If a vegan-labelled soup is needed, check the exact can’s suitability statement and read its allergen and cross-contact warnings separately.
