Eating supper alone
If you want a warm cupboard meal without planning another serving, compare the can size with what you would actually eat. Heinz lists a 300g Cream of Tomato Soup; Tesco gives nutrition for its 400g version per half can.
Who is this for?
Checking salt or milk ingredients
Read the label for the portion you intend to eat. Tesco lists 1.1g salt per half can of Heinz Cream of Tomato Soup 400g and identifies milk ingredients. For context, the NHS advises adults to have no more than 6g of salt a day in total.
Happy to use another portion later
A larger can may suit you if you can store the remainder, while a condensed soup may also be useful in a recipe. Follow the opened-pack instructions; Zero Waste Scotland advises keeping leftover tinned soup in an airtight container in the fridge for up to two days.
What should you check?
Choose the format that fits tonight’s portion and preparation first, then check the label details that matter to you.
| Priority | What to check | Your needs |
|---|---|---|
| Portion and leftovers | Compare can weight with the stated serving size. For example, Tesco gives Heinz Cream of Tomato Soup 400g nutrition per half can; Heinz also lists a 300g format. | I would rather finish the soup tonight than open a can I will need to store. |
| Preparation | Check whether the soup is ready to heat or condensed, and follow the preparation directions on the can. Tesco describes Campbell's 295g Cream of Tomato as condensed and suitable for use in recipes. | Late at night, I want to know whether heating is the only step or whether I need to prepare the soup first. |
| Ingredients and salt | Read the current ingredients and allergen information, plus salt for the portion you will eat. Tesco lists milk ingredients and 1.1g salt per half can for Heinz Cream of Tomato Soup 400g; the NHS advises adults to have no more than 6g salt daily. | If milk ingredients or salt matter to me, I need figures and ingredients for this can, not an assumption about tomato soup generally. |
| Opened-can storage | Follow the pack’s after-opening instructions. GOV.UK says to refrigerate food at 5°C or below when its packaging instructs you to refrigerate it after opening; Zero Waste Scotland advises an airtight container and use within two days for leftover tinned soup. | A larger can works for me if I can put the unused soup away promptly and use it in time. |
Common buying mistakes
-
Assuming a 400g can means one serving
Serving information varies by product: Tesco gives nutrition for Heinz Cream of Tomato Soup 400g per half can. Finishing a can and following its labelled serving basis are different things.
Check the serving information before opening it. If you plan to keep some, follow the pack’s storage directions; Zero Waste Scotland advises transferring leftover tinned soup to an airtight container and refrigerating it for up to two days.
-
Taking “cream of tomato” to mean dairy-free
Heinz lists dried skimmed milk, cream and milk proteins in its Cream of Tomato Soup ingredients. A vegetarian description does not tell you whether a product contains milk.
Read the ingredients and allergen information on the exact can if milk or another ingredient matters to you. Tesco advises checking the current pack because recipes can change.
-
Comparing can sizes without considering preparation
A compact can is not automatically a heat-and-eat portion. Tesco describes Campbell's Cream of Tomato Soup 295g as condensed and also suitable for recipes.
Check its preparation and serving instructions before choosing it for a low-effort supper. If you want to avoid leftovers, compare the amount you will eat rather than can weight alone.
-
Reading salt per serving but eating the whole can
Tesco lists 1.1g salt per half can of Heinz Cream of Tomato Soup 400g. That figure describes the labelled portion, not the entire can.
Use the nutrition panel for the amount you expect to eat. The NHS advises adults to have no more than 6g of salt across the whole day, including salt already in food.

Questions about portions and storage
Is a 400g can always one serving?
No. Check the serving information on the particular can: Tesco gives nutrition for Heinz Cream of Tomato Soup 400g per half can. You may choose to eat a different amount, but use the label’s portion basis when reading its nutrition figures.
What should I do with soup left in an opened can?
Follow the pack’s after-opening instructions. GOV.UK says to keep food at 5°C or below if its packaging instructs you to refrigerate it after opening. Zero Waste Scotland advises transferring leftover tinned soup to an airtight container, refrigerating it and using it within two days.
Can I use the online listing to check allergens?
Use the current can label for that decision. Tesco cautions that recipes, ingredients and nutrition information can change. For instance, Heinz lists milk ingredients in its Cream of Tomato Soup, so check the exact pack if you need to avoid milk.
How do I compare salt when eating more than one labelled serving?
Read the salt figure and its serving basis, then account for the amount of soup you intend to eat. Tesco lists 1.1g salt per half can of Heinz Cream of Tomato Soup 400g. The NHS advises adults to have no more than 6g of salt a day in total, including salt already in food.
