How Many Syns in Hollandaise Sauce?

By Jenny Updated

Hollandaise sauce is one of the classic French mother sauces, a glossy emulsion of egg yolks, melted butter, lemon juice and a whisper of cayenne or white pepper. It's the crowning glory of eggs Benedict, the perfect partner for asparagus spears, and a luxurious drizzle over poached salmon or steamed broccoli.

On Slimming World, however, hollandaise sits firmly in the high-syn camp because it's essentially butter held together by yolk — there's almost nothing in it that isn't pure fat. A standard two-tablespoon serving works out at around 3.5 syns, and if you're generous with the ladle over a brunch plate you can easily push past 6 syns before you've touched the food underneath.

That doesn't mean it's off-limits, but it does mean hollandaise is best treated as a deliberate indulgence rather than a casual condiment. The good news is that a little goes a long way: the richness coats the palate, so even a modest spoonful delivers that buttery, tangy hit you're after.

If you adore hollandaise but want to soften the syn impact, there are clever swaps worth trying. A mock hollandaise made with fat-free natural yogurt, a beaten egg yolk, lemon juice, mustard and a pinch of turmeric for colour, warmed gently over a low heat, can drop the syn count dramatically while keeping the silky texture.

Quark-based versions work beautifully too, and a splash of vinegar with cracked pepper mimics the sharp finish. Whichever route you take, weigh your portion rather than eyeballing it — hollandaise is one of those sauces that creeps up on your daily allowance fast.

Pair a small drizzle with plenty of Speed vegetables and lean protein to keep the plate generous.

Lower-syn alternatives

Swaps that keep the feel of the original without the syn hit.

Mock hollandaise (yogurt-based)

1 Syn per serving

Blend fat-free Greek yogurt with a beaten egg yolk, lemon juice and mustard, warmed gently over low heat. The result is silky and tangy for roughly 1 Syn (the egg yolk) instead of the 3.5 Syns a traditional 30g hollandaise costs. It works beautifully over asparagus and eggs Benedict.

Mustard (English or wholegrain)

Free

English mustard is Free on Slimming World and brings a sharp, punchy hit to eggs Benedict and poached fish that replaces the richness hollandaise provides. A generous smear cuts through the richness of egg yolks and ham without spending any Syns.

Knorr or Colman's hollandaise mix

2 Syns per 30g made up

Packet hollandaise mixes from Knorr and Colman's are approximately 2 Syns per 30g serving when made up — about 1.5 Syns less than premium jar or homemade butter versions. They are a convenient middle ground when you want the real hollandaise taste at a slightly lower Syn cost.

FAQs

How many syns in hollandaise sauce?

Hollandaise sauce is approximately 2 Syns per tablespoon (15g) on Slimming World, rising to about 3.5 Syns for a 2-tablespoon (30g) serving. A 50g portion is roughly 6 Syns, and 100g climbs to around 12 Syns. The butter and egg yolk base makes it one of the richer sauces on the plan. Packet mix versions like Knorr are lower at about 2 Syns per 30g.

Is hollandaise sauce free on Slimming World?

No, hollandaise sauce is not Free on Slimming World. It is essentially an emulsion of butter and egg yolks, making it high in fat and Syns at roughly 3.5 Syns per 2-tablespoon serving. For a much lower-Syn alternative, make a mock hollandaise with fat-free yogurt, a beaten egg yolk, lemon juice and mustard warmed gently — it drops the Syn cost significantly.

Can you have eggs Benedict on Slimming World?

Yes. Poached eggs on a toasted HExB English muffin with lean ham and a measured 2-tablespoon portion of hollandaise at 3.5 Syns makes a satisfying brunch. The eggs, ham and muffin (as HExB) can all be Free or very low Syn, so the hollandaise is the main cost. Use a mock hollandaise with fat-free yogurt to bring it even lower.

How do you make low syn hollandaise?

Mix fat-free natural yogurt with a beaten egg yolk, lemon juice, a teaspoon of mustard and a pinch of turmeric for colour. Warm gently over a low heat, stirring constantly — do not boil or it will split. This mock hollandaise costs roughly 1 Syn for the egg yolk compared to 3.5 Syns for a 30g serving of traditional butter-based hollandaise.
