How Many Syns in Gravy (Bisto made up)?
By Jenny Updated
Gravy is the unsung hero of a proper British dinner, and the good news for anyone on Slimming World is that a ladleful of Bisto made up to packet instructions will set you back surprisingly few Syns. The standard granules whisked with hot water give you roughly 1 Syn per 100ml of finished gravy, which is generous when you consider how much flavour a glug brings to a plate of roast chicken, mashed potato, or a Sunday joint. The reason it stays low is simple: the granules are diluted heavily, so the fat and starch that drive the calorie count are spread across a large volume of liquid. Pour with a sensible hand and you can dress an entire roast for 2 Syns without blinking.
Where people come unstuck is the jug. A casual pour at the table easily tips past 150ml, and if you go back for seconds on a Yorkshire pudding you can quietly spend 4 or 5 Syns on gravy alone. Measure into a small jug before you sit down, or use a tablespoon ladle, and the numbers stay honest. The Best version, Bisto Favourite, and the reduced-salt range all sit in roughly the same Syn bracket per 100ml, though the chicken and onion variants can drift a touch higher or lower depending on the fat content. Always weigh or measure rather than eyeball.
If you want gravy that costs nothing on a green day, a homemade version built from Bovril or a Marmite-spiked stock with cornflour and pan juices (fat skimmed) can come in close to free. But for ease, flavour, and that proper Sunday-dinner taste, made-up Bisto is one of the better Syn investments on the plan. Pair it with Speed veg and lean protein and you have a satisfying roast for a single-figure Syn total.

Lower-syn alternatives
Swaps that keep the feel of the original without the syn hit.
Homemade stock-based gravy
0.5 Syns per 100mlMake gravy from Bovril or Marmite dissolved in hot water, thickened with a teaspoon of cornflour mixed with cold water. Skim any fat from roasting juices before adding. This version can come in under 0.5 Syns per 100ml, saving you even the modest 1 Syn Bisto costs.
Bisto Reduced Salt granules
1 Syn per 100mlIf you are watching sodium intake alongside Syns, Bisto Reduced Salt granules carry the same 1 Syn per 100ml as standard but with 25% less salt. The taste difference is minimal once poured over a roast, and your blood pressure will thank you.
FAQs
How many syns in gravy?
Made-up Bisto gravy is approximately 1 Syn per 100ml on Slimming World, which is remarkably low for the flavour it delivers. A generous 200ml serving is about 2 Syns, and even a full 300ml jug is only 3 Syns. The dilution keeps it light — the granules are spread across a large volume of water. It is one of the best Syn investments for a proper roast dinner.
Is gravy free on Slimming World?
Bisto gravy is not technically Free — it is approximately 1 Syn per 100ml made up. However, a tablespoon at 15ml is only 0.5 Syns, so a modest pour barely dents your daily allowance.
