Parents packing a hot lunch
Compare the amount likely to be eaten, not just the figure on the front of the can. A soup that needs heating also calls for a school-permitted serving arrangement.
Who is this for?
Pupils considering a lighter soup
A calorie figure does not describe the whole lunch. Central and North West London NHS Foundation Trust’s School Health Service advises teenagers to consider a mixture of food groups rather than calories alone.
Households checking dietary suitability
Check the exact flavour and current label: the tomato, chicken and other soups described here have different ingredients and allergen declarations. Check accompaniments separately.
What should you check?
Begin with a like-for-like energy comparison, then work out the intended portion and how the soup will be served at school.
| Priority | What to check | Your needs |
|---|---|---|
| Energy and portion | Compare kcal per 100g, then the kcal in the amount being packed. Tesco Groceries lists 26 kcal per 100g and 76 kcal per 295g can for Heinz Weight Watchers Tomato Soup; its Heinz No Added Sugar tomato soup is listed at 68 kcal per 200g half-can. | I want to know what the pupil will actually eat. A half-can figure and a whole-can figure do not describe the same portion. |
| Salt and the whole lunch | Read salt per intended portion alongside energy. Tesco Groceries lists 1.7g salt in the 295g Heinz Weight Watchers Tomato Soup can; Central and North West London NHS Foundation Trust’s School Health Service says teenage eating is not just about calories. | A lower energy figure matters to me, but I also want to consider the soup with the other food packed for lunch. |
| Serving at school | Read the pack’s preparation instructions and confirm the school’s rules on food flasks or heating. For foods that require chilling, safefood advises keeping packed lunches cold with an insulated box or bag. | If soup has to be served hot, I need an arrangement the pupil can use at lunchtime, not just a can that is convenient to buy. |
| Ingredients and allergens | Check the current declaration for the exact flavour and any added bread or toppings. Tesco Groceries lists milk in Heinz Weight Watchers Tomato Soup; Campbell’s Soup UK lists milk and celery in its Cream of Tomato Condensed Soup. | For a pupil with dietary restrictions, a familiar tomato flavour is not enough to establish suitability. |
Common buying mistakes
-
Choosing by a low-fat or calorie cue alone
Energy does not tell you the salt content or describe the rest of the lunch. Tesco Groceries lists 76 kcal and 1.7g salt for the full 295g Heinz Weight Watchers Tomato Soup can.
Compare both figures for the portion being packed, then consider what else will be served.
-
Treating different serving figures as equivalent
A half-can serving, a whole can and a condensed soup measured after preparation refer to different quantities. Campbell’s Soup UK, for example, states its condensed-soup nutrition per 147.5g portion as consumed.
Use kcal per 100g for an initial comparison, then check preparation instructions and calculate the intended lunch portion on a consistent basis.
-
Planning hot soup before checking school arrangements
Tesco Groceries’ instructions for Heinz Weight Watchers Tomato Soup call for heating it before serving. Whether a pupil can use a flask or heating facility depends on the school.
Confirm the school’s arrangements before relying on soup for lunch; follow the food flask manufacturer’s use and cleaning instructions if a flask is permitted.
A suitable food flask or another permitted heating arrangement may be needed.
-
Assuming tomato or vegetable soup is allergen-free
Recipes differ. The researched Heinz Weight Watchers tomato soup contains milk, while Campbell’s Cream of Tomato Condensed Soup contains milk and celery, according to their respective product information.
Read the current label for the exact product and check bread, crackers and toppings separately.
Relevant soup ranges
These range references illustrate different portions and preparation formats; inclusion does not establish that a particular product is available for this lunch.
Heinz
The tomato products listed by Tesco Groceries include a 295g Weight Watchers soup and a 400g No Added Sugar variant with different stated serving sizes.
- Tesco Groceries lists 76 kcal for the whole 295g Weight Watchers Tomato Soup can and 68 kcal for a 200g half-can of the No Added Sugar tomato soup.
- Both researched products contain milk. The 295g can lists 1.7g salt, so compare the intended portion as well as energy.
Campbell’s
Campbell’s Soup UK describes its condensed soups for serving as soup or using in cooking.
- Its product information gives nutrition per 147.5g portion as consumed, allowing a check against the portion prepared at home.
- That prepared-portion basis is not a direct can-for-can comparison with ready-to-heat soup. The researched chicken flavour contains wheat and milk and may contain egg; the tomato flavour contains milk and celery.
Tesco
Tesco Groceries lists own-label Low Fat Tomato and Low Fat Lentil & Vegetable tinned soups alongside branded products in its filtered soup range.
- The listing provides further tomato and lentil-and-vegetable flavours to check when planning lunch.
- Compare the current nutrition and ingredient panels for the exact cans before treating a low-fat name as a calorie or allergen comparison.
M&S
Marks & Spencer lists a 400g Cream of Tomato Soup can and a separate Tomato Soup in a Cup sachet.
- The canned Cream of Tomato Soup lists 63 kcal per 100g, giving a stated basis for comparison with other cans.
- The sachet requires boiling water and is not the same preparation format as a can. Check its own ingredient and allergen information if considering it for school.

Baxters Favourite Scotch Broth 400g
This 400g broth is an option when the pupil wants a meat-based soup. Check the current pack for barley, mutton and beef against dietary requirements, and confirm how it can be heated and served at school.
No image available
Heinz Cream of Mushroom Soup 400g
This 400g mushroom soup offers a different flavour from the tomato cans discussed above. Check the current milk and wheat declarations where relevant, decide how much to pack, and arrange a permitted way to serve it hot.
No image available
Heinz Oxtail Soup 400g
Consider this 400g oxtail soup only if its meat ingredients suit the pupil’s diet. Check the current wheat declaration and pack directions, including preparation and storage if only part of the can will be used.

Crosse & Blackwell Best of British Spicy Parsnip & Carrot Soup 400g
This 400g parsnip-and-carrot soup is another flavour to consider for a hot lunch. Check the current celery, milk and wheat declarations, and confirm that its heating directions fit the school’s arrangements.

Itoen Special Rich Corn Potage Soup 185g
The 185g can is a smaller pack to assess against the pupil’s intended lunch portion. Check the current pack’s sugars and carbohydrate figures before using them for a comparison, and review its milk and chicken-flavouring ingredients for dietary suitability.
Questions about soup for school lunch
Does a lower calorie figure make a soup a complete school lunch?
No. Check the amount being served, salt, allergens and what else is packed. Central and North West London NHS Foundation Trust’s School Health Service advises that teenage eating involves a mixture of food groups, not calories alone.
Can a pupil eat tinned soup at school without preparing it?
Do not assume so. Tesco Groceries’ instructions for Heinz Weight Watchers Tomato Soup say to heat it and check that it is hot before serving. Confirm the school’s rules and whether a permitted flask or heating facility will work before planning it as a packed lunch.
Is tomato soup automatically vegetarian or free from allergens?
No; check the exact recipe. Tesco Groceries labels Heinz Weight Watchers Tomato Soup vegetarian but lists milk, while Campbell’s Soup UK lists milk and celery in its Cream of Tomato Condensed Soup. Use the current pack label for the product being served.
How should an opened can of soup be kept?
Follow that product’s storage instructions. Marks & Spencer directs customers to put opened Cream of Tomato Soup in an airtight container, refrigerate it and eat it within two days; check other cans for their own instructions.
Is soup in a cup interchangeable with a tin for school lunch?
No. Marks & Spencer’s Tomato Soup in a Cup is a sachet that requires boiling water. Consider access to a suitable hot-water arrangement and check its own nutrition and allergen information rather than treating it as the same product as canned soup.
