Parents packing a hot school lunch
Work out how much soup the pupil will eat, count the other lunch items and check whether the school permits a flask.
Who needs to check what?
Families avoiding particular ingredients
Check the exact pack rather than relying on the flavour name. The compared products include soups listing milk or wheat, while M&S Minestrone lists wheat and celery and carries further allergy suitability warnings.
Households considering own-label soup
ASDA Hearty Vegetable and Tesco Cream of Tomato provide labelled half-can energy values. Calculate the portion being packed and check its current ingredients before choosing between them.
What matters when choosing?
Start with the portion going into the lunch, then check the rest of the meal, the ingredients and the arrangements for serving soup hot.
| Priority | What to check | Your needs |
|---|---|---|
| Portion energy | Check whether the kcal figure is per 100g, half can or full can. ASDA Groceries lists 88 kcal per half can for ASDA Hearty Vegetable 400g; Tesco Groceries lists 116 kcal per half can for Tesco Cream of Tomato 400g. | If I pack a whole 400g can, I need to count both half-can portions: 176 kcal for that ASDA soup or 232 kcal for that Tesco soup, before adding anything else. |
| The complete lunch | Count sides and drinks against the chosen lunch limit. The NHS suggests basing the main lunchbox item on foods such as bread, rice, pasta or potatoes and adding vegetables. | I want to plan what goes with the soup, rather than treating its calorie figure as the total for lunch. |
| Ingredients | Read the current pack’s ingredients and allergen information for the exact recipe. Compare salt for the amount that will be eaten, not just the labelled serving. | Where an ingredient must be avoided, a tomato or vegetable flavour name alone does not tell me whether this particular soup is suitable. |
| Hot-food arrangements | Follow the can’s heating and reheating directions. Check the school’s flask rules and whether the pupil can use the flask at lunchtime. | For a hot lunch, I need a workable way to carry and serve the soup without assuming there is a school microwave. |
Common packed-lunch mistakes
-
Counting a half-can figure for a whole can
A 400g can may be labelled as two servings. Counting one half-can serving when packing both gives the wrong lunch total.
If the pupil will eat the full can, double its half-can kcal figure, then count the other lunch items.
-
Treating soup calories as the whole lunch
A soup that fits below the chosen limit leaves the contents of the rest of the lunch undecided. NHS lunchbox guidance suggests including a carbohydrate-based item and vegetables.
Plan the accompanying food and drink as well as the soup, according to the pupil’s needs and school rules.
-
Choosing by flavour without checking the pack
The compared tomato and vegetable soups list different allergens; a flavour name cannot establish suitability for an allergy.
Read the current ingredients and allergen warnings, and compare salt for the portion being packed.
-
Assuming the soup can be reheated at school
Heating directions differ. ASDA Hearty Vegetable Soup’s product instructions say not to reheat it.
Follow the exact pack directions and check the school’s arrangements before planning to send heated soup in a flask.

Questions about portions and packing
Does the 500-calorie limit apply just to the soup?
No: if you are using that limit for the complete lunch, count the soup as eaten plus every side and drink. ASDA Groceries and Tesco Groceries list the four compared 400g vegetable and tomato soups at 176–232 kcal per full can; those figures do not include anything served alongside them.
When should I double the kcal figure on a soup can?
Double a half-can figure when the pupil will eat the whole two-serving can. For example, ASDA Groceries lists 88 kcal per half can for its 400g Hearty Vegetable Soup, making 176 kcal for the full can.
Can heated tinned soup go in a school flask?
A thermos flask can keep food warm, according to Wirral Community Health and Care NHS Foundation Trust, but follow the soup’s heating directions and check the school’s rules first. ASDA Hearty Vegetable Soup’s instructions say not to reheat it, so do not plan to heat it again at school.
Which ingredients need checking in these soup examples?
The listed Heinz and Tesco cream-of-tomato soups contain milk, while the compared ASDA and Heinz vegetable soups contain wheat. Marks & Spencer lists wheat and celery in its Minestrone and gives additional milk- and egg-allergy suitability warnings. Check the current pack for the exact soup being served.
How do I know whether the school permits hot soup?
Check the individual school’s packed-lunch policy for flasks and hot food rather than assuming reheating facilities are available. Department for Education school-food guidance applies to England and addresses schools and caterers; it does not tell you a particular school’s arrangements for a lunch brought from home.
