Students stocking a first shared kitchen
If you want soup that can be heated without dilution, check the preparation and storage instructions alongside the calories for the portion you expect to eat.
Who is this for?
Students counting a complete meal
A half-can figure will not describe a whole-can lunch. You will also need to count anything served with the soup to know whether the finished meal stays under 500 calories.
Vegetarian or allergen-aware buyers
Check suitability and ingredients on the exact flavour. A vegetarian label does not establish that a soup is free from milk or other allergens.
What should you check?
Work out the amount you will eat first, then compare the label and preparation directions for that amount rather than relying on a front-of-pack serving.
| Priority | What to check | Your needs |
|---|---|---|
| Meal calories | Find out whether energy is listed per 100g, half can or whole can. Calculate the amount you will eat, then add any sides or toppings. Tesco lists Heinz Cream of Tomato Soup 400g at 102 kcal per half can, or 204 kcal for the whole can. | I might eat the entire tin, not the labelled serving, and want the complete meal to stay under 500 calories. |
| Salt | Compare salt for the portion you will eat, not just the displayed serving. Tesco lists 1.1g per half can for Heinz Cream of Tomato Soup 400g, making 2.2g for the can; the NHS advises adults to have no more than 6g a day. | A soup can fit my calorie limit while still contributing salt, so I want to compare both figures. |
| Ingredients | Read the vegetarian declaration and allergen statement for the exact flavour. Check named ingredients such as milk, wheat, barley or celery where relevant. | If I avoid a particular ingredient, the flavour name or a vegetarian label alone is not enough to decide. |
| Preparation | Check whether the soup is ready to heat or condensed. Campbell's Condensed Cream of Mushroom Soup 295g is mixed with water or milk; milk and other additions change the finished meal's calorie total. | For a quick meal in a new kitchen, I would rather know whether I need anything besides the soup and a way to heat it. |
| Storage | Read the unopened-storage and after-opening directions on the exact product. Plan for refrigeration if the label calls for it. | Before stocking a cupboard, I need to know whether a soup actually belongs there and what to do with leftovers. |
Common buying mistakes
-
Reading a half-can figure as a whole-can total
Tesco lists 102 kcal per half can for Heinz Cream of Tomato Soup 400g, while Sainsbury's lists 114 kcal per half can for its Cream of Tomato Soup 400g. Eating either full can doubles its displayed half-can figure.
Check the serving size and number of servings, then calculate calories for the amount you plan to eat: 204 kcal or 228 kcal for these respective full cans, before additions.
-
Choosing on calories alone
Tesco lists WW Carrot & Lentil Soup 295g at 87 kcal and 1.8g salt per can. The calorie figure does not describe its salt content.
Compare both figures for your planned portion. For context, the NHS advises adults to have no more than 6g of salt a day.
-
Assuming vegetarian means dairy-free
The examined Heinz and Sainsbury's tomato soups are labelled vegetarian but contain milk. Campbell's condensed mushroom soup contains milk and wheat.
Read the ingredient and allergen declaration on the exact tin whenever an ingredient matters to you.
-
Forgetting what goes into condensed soup
Campbell's Condensed Cream of Mushroom Soup 295g is intended to be mixed with water or milk, so the soup's as-sold nutrition does not necessarily describe the finished bowl.
Count any milk and other additions, as well as bread or toppings, before deciding whether the meal meets your calorie limit.
Brand references for comparing soups
These references concern particular products or ranges, not every soup carrying the same brand name. Check the current label of the flavour and pack you choose.
Heinz
Cream of Tomato Soup 400g is a ready-to-heat vegetarian tomato option.
- Tesco lists 102 kcal and 1.1g salt per half can: 204 kcal and 2.2g salt for the can.
- This particular soup contains milk; other Heinz flavours need their own label check.
Campbell's
Condensed Cream of Mushroom Soup 295g is an option when you want to dilute soup or use it in cooking.
- The listed preparation allows mixing with water or milk.
- Count the nutrition of milk if you use it, and check the milk and wheat allergens.
Tesco
Tesco product listings provide a way to compare the stated serving basis of individual tinned soups.
- Its listings state per-can energy for WW Carrot & Lentil Soup 295g and per-half-can energy for Heinz Cream of Tomato Soup 400g.
- Convert those different serving bases before comparing a whole-can meal.
Sainsbury's
Its Cream of Tomato Soup 400g is a vegetarian own-label example with half-can nutrition values.
- Sainsbury's lists 114 kcal and 0.89g salt per half can, equivalent to 228 kcal and 1.78g salt for the can.
- The product contains milk; vegetarian suitability does not establish dairy-free suitability.
Asda
Asda is a retailer to consider when checking the label of a specific soup, rather than treating a shop or own-label name as a nutrition guide.
- Compare the portion basis and preparation directions of the product you select.
- Do not transfer nutrition values from a branded soup to an Asda own-label soup.
M&S
Chunky Chicken and Vegetable Soup 400g is a ready-to-heat chicken-and-vegetable example.
- Marks & Spencer lists 44 kcal and 0.48g salt per 100g, equivalent to 176 kcal and 1.92g salt for the can.
- Check its celery and barley ingredients if those affect your choice.
Joybuy soup options
These options are a mushroom soup and a snow fungus soup. For a student move-in, compare the calories for the whole pack and the storage directions before planning either as part of an under-500-calorie meal.

Heinz Cream of Mushroom Soup 400g
If you plan to eat the whole 400g pack, use its full-pack calorie and salt totals rather than a smaller labelled portion. Check the ingredient declaration for milk and wheat if relevant, and count any sides separately.
Image unavailable
Bestore Stewed Snow Fungus Soup 200g
For a whole-pack meal calculation, check the calorie figure for all 200g and include anything served with it. Its product directions call for refrigeration before opening, so plan fridge space rather than cupboard storage; check the pack label when comparing salt.
Questions about tinned soup
How can I check whether a tinned-soup meal is under 500 calories?
Calculate calories for the amount of soup you will eat, then add any sides, toppings or preparation ingredients. Double a per-half-can figure if you eat the whole can; for a per-100g figure, multiply it by the number of 100g portions you eat. The NHS notes that nutrition information is given per 100g or 100ml and sometimes per portion.
Is a lower-calorie soup necessarily lower in salt?
No. Tesco lists WW Carrot & Lentil Soup 295g at 87 kcal and 1.8g salt per can, so compare both values for the amount you will eat. The NHS advises adults to have no more than 6g of salt a day.
Does vegetarian tinned soup contain dairy?
It can. The examined Heinz and Sainsbury's cream of tomato soups are labelled vegetarian but contain milk. Read the exact product's ingredient and allergen declaration if you need to avoid dairy or another ingredient.
What should I do with soup left after opening a tin?
Follow the storage directions on the exact tin, including its refrigeration and use-after-opening instructions. Plan for a suitable covered container if you will not finish the soup at once.
Can tinned soup be used after its best-before date?
A best-before date concerns quality: GOV.UK says tinned food is usually safe after that date but may not be of the same quality. Follow the product's storage instructions and assess the condition of the tin and food; do not apply best-before guidance to a product marked with a use-by date.
