Solo diners who want to heat and serve
A ready-to-heat soup keeps preparation to the steps on the tin. If you use a microwave, decant it into a microwave-safe bowl rather than heating the metal can.
Who is a single tin suited to?
Viewers who prefer beans or vegetables in the bowl
A bean or lentil recipe offers a different texture from smooth tomato soup. Check the serving statement as well as the ingredients: Sainsbury's labels its 400g Tomato & Three Bean Soup as two servings.
Shoppers checking salt or allergens
Compare salt for the amount you will eat, not just the amount shown for one labelled serving. Recipes differ, so check the current tin's ingredients and highlighted allergens before choosing.
What should you check before choosing?
Decide whether you want soup to heat and eat or a condensed ingredient for cooking, then compare portions, ingredients and preparation instructions.
| Priority | What to check | Your needs |
|---|---|---|
| Preparation | Look for ready-to-heat or condensed wording. Follow the tin's hob or microwave instructions; microwave preparation calls for a suitable bowl, not the metal can. | I want to heat soup and sit down to eat, rather than use it as an ingredient in a cooked dish. |
| Portion and texture | Check how many servings the tin states and whether its nutrition figures are per 100g, per half-can or per can. Sainsbury's labels its 400g Tomato & Three Bean Soup as two servings, with 4.4g fibre and 6.8g protein per half-can. | A smooth bowl may be what I fancy, or I may prefer a recipe with beans and lentils. I want the figures to reflect the amount I will actually eat. |
| Salt | Compare figures on the same portion basis. Tesco Groceries lists 1.1g salt per half-can for Heinz Cream of Tomato 400g; Sainsbury's lists 0.8g per half-can for Heinz No Added Sugar Cream of Tomato 400g. | I'm checking the soup alongside the rest of my meal, especially if I plan to eat the whole tin. |
| Ingredients and allergens | Read the current pack, particularly when a recipe or dietary restriction matters. Campbell's Soup UK lists milk and celery in its Condensed Cream of Tomato Soup; ingredients differ between products. | I need to know whether this particular tin fits my dietary requirements, rather than relying on a range name or an older listing. |
Common mistakes to avoid
-
Assuming one tin means one labelled serving
A 400g tin can be labelled as two servings. Sainsbury's says this of its Tomato & Three Bean Soup, so figures given per half-can do not describe the whole tin.
Check the serving statement and compare nutrition for the quantity you intend to eat.
-
Reading “less salt” as “no salt”
Sainsbury's lists 0.8g salt per half-can for Heinz No Added Sugar Cream of Tomato Soup, despite its 25% less salt claim relative to standard Heinz Cream of Tomato Soup.
Compare the salt figures on the same serving basis and account for how much soup you will have.
-
Putting the metal tin in the microwave
The microwave directions on the Sainsbury's and Heinz products call for the soup to be transferred to a microwaveable dish or bowl.
Decant it, then follow the product's directions for covering, stirring and checking that it is piping hot.
-
Relying on an older allergen listing
Recipes and packaging information can change. The products discussed here include soups listing milk or celery, while M&S Food warns that its online ingredient and allergen information may change.
Check the ingredients and highlighted allergens on the tin you are buying.
Brand and range references
Heinz
The 400g Cream of Tomato tins considered here include a standard recipe and a No Added Sugar version.
- The two tomato versions give shoppers distinct salt figures to compare: Tesco Groceries lists 1.1g per half-can for the standard soup, while Sainsbury's lists 0.8g per half-can for No Added Sugar.
- Check the current pack for milk and other ingredients; “no added sugar” does not mean salt-free.
Campbell's
Campbell's Soup UK presents its Condensed Cream of Tomato Soup as an option for cooking, rather than simply a ready-to-heat bowl.
- A condensed format is worth considering when the soup will become part of a cooked TV dinner.
- Campbell's lists milk and celery, and gives 1.34g salt per 147.5g portion. Check its preparation directions and portion basis before comparing it with a 400g ready-to-heat tin.
Sainsbury's
The own-label 400g soups considered here include Cream of Tomato and Tomato & Three Bean.
- Sainsbury's labels Tomato & Three Bean as two servings and lists 4.4g fibre and 6.8g protein per half-can.
- That soup lists 0.95g salt per half-can. For Cream of Tomato, Sainsbury's directs shoppers to transfer leftovers to a non-metallic lidded container, refrigerate them and use them within two days.
M&S
M&S Food lists 400g Cream of Tomato alongside vegetable and bean-based tinned soups.
- The listed recipes give a choice between a smooth tomato soup and soups with different ingredients and textures.
- M&S Food lists 0.45g salt per 100g for its Cream of Tomato and warns that online ingredient and allergen details may change; check the current pack.

Baxters Chef's Selection Lobster Bisque Soup 400g
Consider this bisque if you want a single tin for a solo meal and can heat it on the hob. The product information describes it as serving one and gives a gentle heating time of 3–4 minutes; check the current pack for preparation directions. Its listed ingredients include white wine and French brandy, and its identified allergens include crustaceans, milk, sulphites and celery.

Baxters Super Good Pea, Broccoli & Basil Pesto Soup 400g
This pea and broccoli recipe is an option if you prefer a vegetable-and-pulse soup. The product information describes hob and microwave methods and lists 1.83g salt per can. Check the tin's serving statement and current ingredients, including milk and pine nuts, before choosing it for your meal.
Image unavailable
Heinz Cream of Mushroom Soup 400g
This smooth mushroom soup is a choice when you want a familiar heat-and-serve format. The product information describes hob and 850W microwave directions and labels the can as two servings. If you plan to eat the whole tin, use that amount when comparing nutrition; check the current label for milk and wheat.
Image unavailable
Suma Organic Tuscan Bean Soup 400g
Choose this bean soup to consider a different recipe from smooth tomato or mushroom soup. It is described as ready to heat and serve; check the tin for the heating method and serving size you need. The product information identifies celery and gives salt per 100g, so compare that figure using your intended portion.
Image unavailable
Suma Pea & Vegan Ham Soup 400g
This pea-based soup is another alternative to a smooth soup; check the tin for the serving size and heating method that suit your dinner. Its product description calls it vegan-friendly, but the listed ingredients include milk and the allergen information identifies wheat, soy and milk. Do not rely on the vegan wording without checking the current pack.
Questions about tinned soup
Can I heat tinned soup in the microwave?
Yes, if the product gives microwave directions, but do not microwave the metal tin. Transfer the soup to a microwave-safe bowl and follow the instructions for covering, stirring and checking that it is piping hot.
Does a 400g tin count as one serving?
Not necessarily: Sainsbury's labels its 400g Tomato & Three Bean Soup as two servings, while some soup nutrition figures are given per half-can. Check the particular tin and compare figures for the amount you intend to eat.
What if I want beans or lentils rather than smooth soup?
Choose a recipe that lists the ingredients you want, then check its portion and nutrition information. Sainsbury's Tomato & Three Bean Soup, for example, lists 4.4g fibre and 6.8g protein per half-can, according to its product page; the 400g tin is labelled as two servings.
How should I compare salt between tins?
Compare salt on the same portion basis and allow for how much of the tin you will eat. Tesco Groceries lists 1.1g per half-can for standard Heinz Cream of Tomato 400g; Sainsbury's lists 0.8g per half-can for Heinz No Added Sugar Cream of Tomato 400g. A relative less-salt claim does not mean a soup contains no salt.
What should I do with soup left after opening a tin?
Follow that product's storage directions. Sainsbury's instructs shoppers to transfer unused Cream of Tomato Soup to a non-metallic lidded container, refrigerate it and use it within two days; check the directions on other tins rather than assuming they are identical.
