Solo starter shoppers
If soup comes before a larger Christmas main course, the tin's serving count helps you decide how much to heat and whether you will use the remainder.
Who is choosing soup for one?
Vegetarian or vegan diners
Check the declaration and ingredients on the exact soup. If an allergy is involved, read its allergen statement separately: a vegan label alone does not establish allergy suitability.
Shoppers comparing salt
Look at salt per 100g and per intended bowl. The amount in a half-tin starter will differ from the amount in a whole tin, even when the recipe is unchanged.
What matters when choosing?
Decide whether the soup is a starter or the meal, then compare the information on the exact tin against the portion you plan to serve.
| Priority | What to check | Your needs |
|---|---|---|
| Portions and leftovers | Read the servings per tin and the nutrition panel's portion size. Check the opened-tin storage instructions before planning a second bowl. | I want a small starter without heating more than I intend to eat. Tesco Groceries and Sainsbury's list half a 400g tin as a serving for their cream-of-tomato soups. |
| Ingredients and allergens | Check the exact product's vegetarian or vegan declaration, ingredient list and allergen statement. Do not use a flavour name as a substitute. | If I am serving someone who avoids particular ingredients, I need to check the tin itself. Marks & Spencer labels its Spiced Lentil and Tomato Soup vegan but also says it is not suitable for people with milk or egg allergy. |
| Salt and nutrition | Compare salt per 100g on a consistent basis, then calculate the amount from the labelled serving you will actually eat. Check other nutrition values using the same basis. | For a soup served alongside other Christmas dishes, I want to know the salt in my bowl. The NHS describes more than 1.5g salt per 100g as high and advises adults to have no more than 6g a day in total. |
| Heating and timing | Follow the product's hob or microwave directions, including any stirring or heating instructions. Check preparation directions for condensed soup rather than treating tin size as a ready-to-serve portion. | I need a soup I can prepare while the rest of dinner is underway, using the equipment available in my kitchen. |
What should you avoid overlooking?

Assuming a 400g tin means one serving
Tesco Groceries and Sainsbury's each list two half-tin servings for their 400g cream-of-tomato soups. A whole tin may be more than you want before a larger main course.
Check the serving count and heat the amount you plan to eat. Follow that tin's instructions if you are keeping the remainder.
-
Choosing by flavour name instead of ingredients
A tomato or lentil description does not settle dietary or allergy suitability. Marks & Spencer's vegan-labelled Spiced Lentil and Tomato Soup carries a milk- and egg-allergy suitability warning.
Read the current ingredient and allergen statement on the exact tin, particularly when serving someone with an allergy.
-
Comparing salt using different portion sizes
Heinz Cream of Tomato Soup lists 1.1g salt per half tin on its Tesco Groceries listing, while another label may show a different serving size. Those figures cannot be compared fairly without checking the basis.
Use the per-100g values for comparison, then check the salt for the amount you intend to serve.
-
Relying on an older product listing
Ingredients and preparation directions can change, so a previous listing may not describe the tin in your cupboard.
Before serving, check its current ingredients, allergens, date marking and heating instructions.
Brand and product-line references
These examples show differences to check on specific soups; they do not describe every product made by each brand.
Heinz
Tesco Groceries lists Heinz Cream of Tomato Soup as a 400g vegetarian option with nutrition stated per half tin.
- The half-tin nutrition basis is useful when planning a starter.
- The Tesco listing gives 1.1g salt per half tin; check the exact product's ingredients and allergens before serving.
Tesco
Tesco Cream of Tomato Soup is a 400g own-label option whose listed serving is half a tin.
- A stated half-tin portion makes it easier to plan a starter and a second serving.
- Its Tesco Groceries listing gives 1.12g salt per half tin; read the current tin for dietary and storage details.
Sainsbury's
Sainsbury's lists two servings for its 400g Cream of Tomato Soup.
- The stated serving count offers a clear basis for dividing the tin between two bowls.
- Check the exact tin's allergen and leftover-storage instructions before serving or keeping any soup.
M&S
Marks & Spencer lists both a vegetarian Cream of Tomato Soup made with double cream and a vegan-labelled Spiced Lentil and Tomato Soup.
- The two products offer different ingredient and texture routes for a starter or light meal.
- Marks & Spencer says the vegan-labelled lentil soup is not suitable for people with milk or egg allergy; check the specific product rather than relying on its vegan label.
Campbell's
Tesco Groceries lists 295g Campbell's condensed Cream of Mushroom, Cream of Chicken and Cream of Tomato soups.
- The listed condensed format provides another tin size and flavour range to consider.
- Check the chosen flavour's serving count, preparation method, nutrition and allergens before deciding how it fits a meal for one.

Heinz Cream of Mushroom Soup 400g
A cream-of-mushroom soup to consider if that flavour suits your Christmas menu. The tin is 400g; check its serving size, ingredients and heating directions to plan your bowl.
No image available
Heinz Scotch Broth Soup 400g
Scotch broth is an option to consider when soup is the light meal rather than a small tomato starter. This 400g tin contains mutton and barley, so it is not a vegetarian choice; check the tin's portion guidance and allergen statement.
No image available
Heinz Big Soup Steak & Potato 400g
Consider this beef-and-potato soup if the soup itself will be your light meal. It is a 400g tin and is not suitable for vegetarian diners; check its serving guidance before deciding how much to heat.
No image available
Itoen Special Rich Corn Potage Soup 185g
The 185g corn-potage tin is a different size and flavour from the 400g options. Check the current tin for its serving count, preparation directions, ingredients and nutrition before treating it as one starter portion.
Questions about portions and labels
Is a 400g tin of soup one serving?
Not necessarily. Tesco Groceries and Sainsbury's list two half-tin servings for their 400g cream-of-tomato soups. If you want a starter before a larger Christmas meal, check the serving size on your chosen tin and plan what to do with the remainder.
How long can I keep soup left in an opened tin?
Follow the storage instructions on the exact soup you bought. Check whether you need to transfer the remainder to another container, refrigerate it and use it within the period stated on that tin; do not assume every soup has the same instructions.
How can I compare salt when tins list different servings?
Compare their salt figures per 100g first, then check the amount for the portion you intend to eat. The NHS describes more than 1.5g salt per 100g as high and advises adults to have no more than 6g salt a day in total.
Does a vegan soup label settle allergy suitability?
No. Read the exact product's ingredient and allergen statement. Marks & Spencer lists its Spiced Lentil and Tomato Soup as vegan but says it is not suitable for people with milk or egg allergy.
What should I check on a UK soup tin before serving?
Start with the ingredients and allergens, the quantity, serving and nutrition information, and the heating and storage directions relevant to your meal. UK food-labelling guidance from GOV.UK requires prepacked food information to include an ingredient list with allergens and the food's weight or volume; use the current tin when making your final checks.
