How Many Syns in Campbells Condensed Soup?

By Jenny Updated

Campbells Condensed Soup is one of those store cupboard heroes that has been bailing out British cooks for generations. It is that iconic red and white tin tucked behind the baked beans, ready to become a quick lunch, a creamy pasta bake binder, or the secret ingredient in a tuna mornay. On Slimming World, however, it sits firmly in the syn-counted aisle rather than the Free Food shelf, and the way you serve it up makes an enormous difference to the final tally.

A standard tin is designed to be diluted, and that instruction matters more than you might think. Made up with water, a 300ml serving of cream of tomato lands at around 3 syns, which is perfectly manageable for a cosy lunch with a Hi-fi bar on the side. Swap that water for semi-skimmed milk straight from the carton and the syns climb, plus you lose the option to count the milk as part of your Healthy Extra A allowance. The trick is to make it up with water, then stir in a measured 350ml of skimmed milk from your HEx A pour at the end, giving you creamy richness without the bonus syns.

Flavour choice also influences your spend. The cream-based varieties such as cream of chicken, cream of mushroom and cream of tomato hover around 3 syns per made-up portion, while chunky and broth-style soups tend to come in lower. Avoid pouring the condensed contents neat into a casserole as a shortcut sauce, because the whole tin can rack up 6 syns or more in one go. Decant carefully, measure properly, and Campbells slots neatly into a slimmer's week as a comforting nostalgic treat rather than a hidden syn trap.

Homemade vegetable soup

Free

Making soup from scratch with Speed vegetables like tomatoes, carrots, onions and celery in stock is completely free on Slimming World. Blend it smooth for a creamy texture without any syns, compared to the 3 syns per serving you would spend on a tin of Campbells cream of tomato.

Baxters Favourites Chicken Broth

1 syn per serving

Ready-to-eat broth-style soups tend to be lower in syns than condensed varieties because they are not concentrated. A tin of chunky chicken broth can come in around 1 syn per serving, saving you at least 1-2 syns compared to the Campbells condensed equivalent.

FAQs

How many syns in Campbells soup?

A 300ml serving of Campbells Condensed Cream of Tomato made up with water is around 3 syns. Cream of chicken and cream of mushroom come in slightly higher at about 4 syns per serving. The chicken broth variety is the lightest at just 2 syns per 300ml serving. Always dilute with water rather than milk to keep the syn count down.

Is Campbells soup free on Slimming World?

No, Campbells Condensed Soup is not free on Slimming World. The condensed format contains added flour, fats and sometimes dried dairy, which means each serving carries syns. A made-up 300ml portion of cream of tomato costs about 3 syns, while using the whole tin undiluted can rack up 6 syns or more.

Can you use Campbells soup in cooking on Slimming World?

Yes, but measure carefully. Using 1 tablespoon of condensed soup as a flavour base in cooking costs about 1 syn, which is manageable in a casserole or pasta bake split between four servings. Avoid pouring the whole tin in neat, as the undiluted contents carry around 6 syns. Divide the total syns across the number of portions the dish makes.

Which Campbells soup is lowest in syns?

Campbells Condensed Chicken Broth is the lowest at around 2 syns per 300ml serving made up with water. The cream-based varieties like cream of tomato, chicken and mushroom all sit between 3 and 4 syns. If you want the absolute lowest syn option, look for broth-style soups and bulk them out with Speed vegetables.
