Who is serving the soup?

Conference caterers serving individual hot lunches

A declared serving count helps plan cans and portions for a scheduled break. The heating method also needs to fit the time and equipment available.

Teams handling vegan or dairy-free requests

A vegan label does not replace a check of the product's allergy advice. Confirm the delivered can against each attendee's requirements before adding it to the menu.

Small venues with limited preparation space

Ready-to-heat and condensed soups involve different work. Condensed soup needs measured dilution before heating, so the preparation area and staff time matter.

What matters when choosing a can?

Start with the portion you intend to serve, then check preparation, dietary information and nutrition on the basis of that portion.

Priority What to check Your needs
Portion count Read the serving declaration, not just the can weight. Tesco Groceries lists one serving per 400g can for Crosse & Blackwell Cream of Tomato, but a half-can serving for Heinz and Tesco 400g cream of tomato soups. I need a clear count for each attendee without deciding how to split cans during the break.
Preparation Match the instructions to the available equipment and staff time. Tesco Groceries gives microwave and hob directions for its ready-to-heat tomato soup; its Campbell's condensed tomato soup listing calls for adding one can of cold water before heating. If the venue has little preparation space, I need a heating plan that works there. A staffed kitchen can accommodate an extra dilution step.
Allergen information Check ingredients and allergy advice on delivered cans, then keep menu information aligned with what is served. The M&S Tomato and Basil Soup page labels it vegan but says it is not suitable for people with milk or egg allergy. Attendees need information about the soup they will actually receive; a vegetarian or vegan label alone does not answer an allergy question.
Nutrition basis Compare values for the portion you intend to serve. Tesco Groceries lists 2.00g salt for the full Crosse & Blackwell 400g can, while its Heinz and Tesco listings give salt figures per half-can serving. When reviewing a menu, I want to compare equivalent portions rather than mistake a half-can value for a whole-can value.

Portioning and preparation mistakes

  • Counting every 400g can as one meal

    Tesco Groceries lists one serving per Crosse & Blackwell 400g can, but half-can servings for the Heinz and Tesco 400g tomato soups. Can weight alone therefore does not give a consistent attendee count.

    Use the serving declaration on the exact product being ordered and confirm that the planned portion fits your serving vessel.

    An incorrect can count can leave surplus soup or too few planned portions.

  • Using a dietary label in place of an allergen check

    Heinz and Tesco cream of tomato soups list milk ingredients, and the Campbell's condensed tomato soup listing declares celery and milk. M&S labels its Tomato and Basil Soup vegan while warning that it is unsuitable for people with milk or egg allergy.

    Build the event's allergen information from delivered labels and keep preparation and serving arrangements consistent with it.

  • Heating condensed soup without diluting it

    Tesco Groceries' Campbell's condensed tomato soup instructions call for liquid to be added gradually before heating. That is a different preparation process from heating a ready-to-heat soup.

    Choose it only when staff can measure, mix and heat it with suitable equipment.

    Dilution adds a preparation step and requires the specified liquid to be available.

  • Finalising menu information from an online listing

    The soup served at the event needs to match the ingredients and allergy information given to attendees.

    Check the labels and best-before dates on delivered cans before finalising the menu and preparation plan.

Brand and product-line references

These examples illustrate serving formats and label checks; a brand name alone does not establish portion size or dietary suitability.

Heinz

Tesco Groceries lists Heinz Cream of Tomato Soup in a 400g can with nutrition stated per half-can serving.

  • A half-can serving basis allows two planned portions from a can.
  • The listed product contains milk; check its delivered label when preparing allergen information.

Tesco

Tesco Cream of Tomato Soup is listed as a 400g ready-to-heat option with microwave and hob instructions.

  • Its listed heating methods give caterers two equipment options to assess.
  • The listing uses a half-can serving basis and declares milk, so plan portions and check allergen information.

Crosse & Blackwell

Tesco Groceries lists the 400g Cream of Tomato Soup pack as containing one serving.

  • The whole-can serving declaration makes a one-can-per-attendee plan straightforward to count.
  • The listing gives 2.00g salt per can; review the delivered label and the intended menu portion.

Campbell's

Tesco Groceries lists Campbell's Condensed Cream of Tomato Soup as a soup requiring dilution before heating.

  • The listed instructions give a defined preparation method for staffed service.
  • The listing states two portions, calls for added liquid and declares celery and milk.

M&S

M&S labels its 400g Tomato and Basil Soup vegan and vegetarian.

  • The vegan designation is relevant when planning a plant-based menu option.
  • M&S says this product is unsuitable for people with milk or egg allergy; establish portions from the delivered pack rather than assuming one can is one serving.

Joybuy tinned soup option

This Joybuy option is a 400g cream of mushroom soup for caterers considering a tinned soup alongside the tomato varieties discussed above.

Heinz Cream of Mushroom Soup 400g can

Heinz Cream of Mushroom Soup 400g

Frequently asked questions

Is one 400g can always one conference serving?

No. Tesco Groceries lists one serving for the Crosse & Blackwell 400g Cream of Tomato can, but a half-can serving for its Heinz and Tesco 400g cream of tomato listings. Calculate quantities from the serving declaration on the product you will use.

Can condensed tomato soup be served individually?

Yes, if staff prepare and portion it according to the product instructions. Tesco Groceries' Campbell's condensed tomato soup listing states two portions and calls for one can of cold water, or a milk-and-water mixture, to be added before heating.

Does vegan tomato soup suit someone with a milk or egg allergy?

Not automatically. M&S labels its Tomato and Basil Soup vegan and vegetarian, but says it is not suitable for people with milk or egg allergy. Check the delivered product's allergy advice against the attendee's requirements.

What allergen information does a conference caterer need to provide?

In England, Northern Ireland and Wales, GOV.UK's allergen guidance says catering businesses must provide allergen information for both prepacked and non-prepacked food and manage allergens during preparation. Check delivered labels against the information given at service; for an event in Scotland, check the applicable Food Standards Scotland guidance.

What should happen to soup left after opening a can?

Follow that product's storage instructions rather than applying one period to every soup. Check the delivered label for the required container, refrigeration instructions and time allowed after opening.
