Gordon Ramsay Cauliflower Soup Recipe

Gordon Ramsay’s cauliflower soup is a creamy blended soup made with a whole cauliflower, chicken stock, milk and double cream (heavy cream), finished with brown butter, truffle oil and crispy sage leaves, served alongside four-cheese toasts. It takes about 25 minutes and serves 4.

This recipe appears as “Cauliflower Soup with Brown Butter and Cheesy Toasts” in Gordon Ramsay’s Quick and Delicious, where he writes: “Making brown butter, or beurre noisette, is one of those techniques that chefs love but home cooks seem to steer clear of because it sounds tricky. Believe me, it’s really not complicated, and the more often you do it, the more confident you become.”

The technique that sets this apart: the brown butter spooned over the finished soup. Heating butter past the melting point until the milk solids turn golden releases a deep, nutty aroma that transforms a simple cauliflower soup into something that smells and tastes like it came from a restaurant kitchen. Combined with truffle oil and fried sage, it adds three layers of flavour on top of the soup without changing the base.

FAQs

What is brown butter and why does Ramsay use it here?

Brown butter, or beurre noisette in French, is regular butter heated past the point where the water evaporates and the milk solids start to toast. The result is a golden-brown liquid that smells intensely nutty and adds a depth that plain melted butter can’t match.

Cauliflower soup on its own is mild and creamy. The brown butter gives it a roasted, almost caramel-like richness without adding any extra cooking time to the soup itself. Ramsay says it’s “such an easy way to add a rich nuttiness to this creamy soup, and it smells incredible.”

Why does he add truffle oil to the brown butter?

Truffle oil and cauliflower is a classic pairing in French cooking because cauliflower’s mild, slightly sweet flavour doesn’t compete with the earthy intensity of truffle. Adding the truffle oil to the brown butter rather than directly to the soup means you get the aroma in concentrated bursts on the surface rather than diluted throughout.

A little goes a long way. One tablespoon stirred into the warm brown butter is enough for four bowls. If you don’t have truffle oil, the brown butter and crispy sage on their own are still a significant step up from serving the soup plain.

How is this different from his saffron version?

The “Saffron & Cauliflower Soup” in Gordon Ramsay’s Sunday Lunch takes a more elegant direction. He poaches the cauliflower in a mixture of chicken stock and milk with saffron strands, which keeps the soup pale and gives it a delicate golden colour and floral aroma.

Instead of brown butter on top, he reserves a quarter of the florets, sautés them golden in foaming butter, and places them in the centre of each bowl with crispy parsley. The Sunday Lunch version is a dinner party starter. The Quick and Delicious version is a weeknight meal with cheesy toasts on the side.

Why does he use milk and cream as well as stock?

Stock alone makes a brothy, thin soup. Ramsay adds equal parts milk and cream to the stock, which gives the soup body and a silky texture without needing to add potato as a thickener.

Milk keeps things light while cream adds richness. His MasterClass version uses the same milk-and-stock combination but skips the cream entirely, producing a leaner soup that he passes through a sieve for a restaurant-smooth finish. The Quick and Delicious version is more indulgent because it’s designed for home cooking where nobody is counting calories.

Why four cheeses on the toasts instead of just one?

Ramsay lists mozzarella, Cheddar, blue and Gruyère but then says “or a combination of whatever you have in the fridge.” The point isn’t the specific cheeses but the mix of textures and flavours they create together.

Mozzarella melts into long stretchy strings. Cheddar adds sharpness. Blue brings a salty punch. Gruyère goes nutty when grilled. Combined, they create a toast that has more going on than a single-cheese version. This is the same approach he uses in his French onion soup from Bread Street Kitchen, where the cheese crouton is built to contrast the sweet onion soup underneath.

Can I make this soup ahead?

Make the soup base up to a day ahead and store it in the fridge. It reheats well over a gentle heat with a splash of extra milk if it has thickened overnight.

Don’t make the brown butter in advance because it loses its aroma as it cools and the sage leaves go limp. Make it fresh in the 2 minutes while the soup reheats and the toasts grill. The cheesy toasts also need to be made last minute because the cheese hardens and the bread goes tough once they cool down. Assembly takes 5 minutes if everything else is prepped.
