Gordon Ramsay’s White Onion Soup Recipe

Gordon Ramsay White Onion Soup Recipe is a silky, pale soup made with butter-sweated white onions, chicken stock, cream and sharp cheddar. It serves four as a starter and takes just 30 minutes from stovetop to table. The recipe comes from Ramsay’s cookbook Great British Pub Food.

Ramsay calls for new season’s white onions because they carry a natural sweetness that yellows cannot match. His version pairs that sweetness with Montgomery cheddar, a strong West Country cheese whose sharpness cuts straight through the cream. The cheddar goes in at the very end, so it melts without splitting.

The whole technique rests on keeping the onions pale. Seven to ten minutes of gentle sweating in butter softens them fully, and any browning will change the soup’s color and taste. A fine sieve after blending removes every last fiber, which is why the texture reads as velvet rather than rustic.

FAQs

Can I use yellow onions instead of white?

Yellow onions will work in a pinch, but the soup will taste noticeably different. White onions carry more water and natural sugar, so they break down into a lighter, sweeter base. Swap in yellows and you lose the pale color and gentle sweetness that define the dish.

Why does this recipe use milk and cream instead of just cream?

The milk thins the soup to the right body without thinning the flavor. Pure cream on its own can make the texture too heavy and coat the palate in a way that masks the onion. Splitting the dairy this way keeps it light enough to serve as a starter.

What kind of cheddar works best?

Montgomery cheddar is the original choice, a cloth-bound West Country cheese with a sharp, tangy bite. Any extra-mature or vintage cheddar with real acidity works the same way, because the point is contrast against the sweet onion base. Mild or medium cheddar disappears into the cream and adds almost nothing.

Do I really need to pass the soup through a sieve?

Passing it through a fine sieve is what separates this from a standard blended soup. Onions contain long cellulose fibers that even a high-speed blender leaves behind, and those fibers create a slightly grainy mouthfeel. One pass with a ladle takes under three minutes and the difference is obvious.

What can I serve alongside this soup?

Buttery scones or crusty bread are the classic pairing, and Welsh rarebit toast works well for a pub-style spread. A warm rosemary olive focaccia gives you a crisp, oil-rich base that soaks up the creamy broth. Keep sides plain so the soup holds the spotlight.

Can I make this soup ahead and reheat it?

The base freezes well for up to two months if you stop before adding the dairy. When ready to serve, thaw overnight, reheat gently, then stir in the milk, cream and cheddar. A thick split pea soup with vegetables stores the same way, so batch both for a freezer rotation.
