Hosts counting the finished serving
If you want a soup course under 500 kcal, work from the amount going into each bowl or cup. A half-can nutrition figure does not describe a whole can, and bread or toppings need counting separately.
Who is this for?
Hosts serving vegetarian guests
Look for an explicit vegetarian declaration rather than judging by the flavour name. ASDA Groceries labels Heinz Vegetable Soup suitable for vegetarians; Ocado labels M&S Pea & Mint Soup vegetarian. The former contains wheat and the latter contains milk.
Hosts checking allergens and leftovers
A mixed soup selection needs a separate label check for every recipe. The listed products identify different allergens, including milk, wheat, egg, celery and barley. Follow each tin’s heating and opened-soup instructions; Ocado’s M&S Pea & Mint listing says not to reheat it.
What should you check?
Start with the calories in the portion you plan to serve, then check dietary suitability and the preparation instructions for each flavour.
| Priority | What to check | Your needs |
|---|---|---|
| Finished portion | Check whether energy is stated per 100g, per half can or per prepared serving. Use the pack weight and serving count to calculate the soup you will serve; count milk, bread and toppings separately. The NHS notes that a manufacturer’s portion may differ from yours. | I want the entire bowl or cup, including anything served with it, to meet my 500 kcal limit—not just the soup figure printed for a smaller portion. |
| Diet and allergens | Check the vegetarian declaration where needed, then read the ingredients and allergen statement on each tin. A vegetable flavour alone does not establish vegetarian or allergen suitability. | Some guests need a vegetarian choice, while others may need to avoid a particular ingredient. I need to be able to identify which soup is which before serving. |
| Salt and richness | Compare salt using the same portion basis, alongside fat and saturates if these matter to your choice. Tesco Groceries lists 1.1g salt per half can for Heinz Cream of Tomato; a whole can is two of those portions. | A lower soup calorie total does not answer every label question for me, especially if I am also putting out bread, butter or cheese. |
| Heating and storage | Read the exact product’s hob or microwave directions and its instructions for opened soup. Ocado’s M&S Pea & Mint listing says not to reheat; follow the instructions on the pack received. | I may heat several tins during the party and have some left over, so I need instructions that fit how I plan to serve and store each one. |
What is easy to overlook?
-
Mistaking half a can for a whole can
ASDA Groceries gives Heinz Cream of Tomato as 102 kcal per half of a 400g can: the soup in the whole can is 204 kcal. Its Heinz Chicken Noodle listing gives 64 kcal per half can, or 128 kcal for the whole can.
Check the labelled portion and net weight before calculating calories for the amount you will heat and serve.
-
Counting the soup but not what goes with it
A soup-only figure excludes bread, butter, croutons, cheese and other additions. A bowl that starts with a soup under 500 kcal is not automatically a finished serving under 500 kcal.
Offer accompaniments separately and count the amounts used if the limit applies to the complete serving.
-
Using calories as a shortcut for other label checks
Flavours with similar calorie totals can have different allergens and salt values. ASDA Groceries lists milk in Heinz Cream of Tomato, wheat in Heinz Vegetable and wheat, egg and celery in Heinz Chicken Noodle.
Read each flavour’s allergen statement and compare salt on a consistent per-100g or per-portion basis.
-
Assuming leftover soup can all be handled alike
Instructions differ by product. Ocado’s M&S Pea & Mint listing says not to reheat, while the cited ASDA Groceries Heinz listings give instructions for refrigerating unused soup.
Check the pack received for heating, storage and reheating directions before planning a second serving.

Common questions
Will a soup under 500 kcal still meet that limit when served?
Only if the complete serving stays under 500 kcal. The cited ASDA Groceries figures put the listed Heinz 400g soups at 128–204 kcal per whole can, and Ocado’s figures put M&S Pea & Mint at 192 kcal per 400g can; those are soup-only totals. Count bread, butter, cheese, croutons, cream or preparation milk separately, using the amounts actually served. The NHS also notes that your portion may differ from the manufacturer’s stated portion.
Which of the cited soups are labelled vegetarian?
ASDA Groceries labels Heinz Vegetable Soup suitable for vegetarians, and Ocado labels M&S Pea & Mint Soup vegetarian. Check the pack before serving: the Heinz soup contains wheat and the M&S soup contains milk.
Do Campbell’s condensed soup calories include milk added during preparation?
No. Tesco Groceries gives 142 kcal for a 147.5g half-can serving of Campbell’s Condensed Cream of Chicken as sold. If you prepare it with the permitted half-milk, half-water mixture, count the type and amount of milk used in the finished serving.
What should I do with opened soup after the party?
Follow the instructions on the particular pack. The cited ASDA Groceries Heinz listings direct you to put unused soup in a suitable container, refrigerate it and eat it within two days. Ocado’s M&S Pea & Mint listing calls for an airtight container in the fridge, consumption within two days and no reheating.
