Gordon Ramsay White Onion Soup Ingredients
- 4 large white onions, thinly sliced
- 2 tbsp unsalted butter
- 2 tbsp olive oil
- 4 cloves garlic, minced
- 4 cups (1 liter) high-quality vegetable or chicken broth
- 1 cup heavy cream
- 1 tsp each of dried thyme, oregano, and rosemary
- Salt and freshly ground white or black pepper, to taste
- Fresh chives and parsley, for garnish
How To Make Gordon Ramsay White Onion Soup
- Caramelize the Onions: In a large pot or Dutch oven, heat the butter and olive oil over a medium-low heat. Add the thinly sliced onions and a generous pinch of salt. Cook slowly, stirring occasionally, for 20-25 minutes. The onions should become very soft, sweet, and a deep golden, jammy consistency. Do not rush this process.
- Sauté the Garlic and Simmer: Add the minced garlic and cook for another 2-3 minutes until fragrant. Pour in the broth, bring the mixture to a boil, then immediately reduce the heat to a low simmer. Let the soup simmer for 15-20 minutes to allow the flavors to meld completely.
- Blend Until Smooth: Let the soup cool slightly. Use an immersion blender to puree the soup directly in the pot until it is completely smooth and velvety. Alternatively, carefully transfer the soup in batches to a regular blender and blend until smooth, then return it to the pot.
- Finish and Serve: Return the pot to a very low heat. Stir in the heavy cream and the dried herbs. Allow the soup to warm through gently, but do not let it boil. Taste the soup and season generously with salt and pepper. Ladle the hot soup into warm bowls and garnish with a sprinkle of fresh chives and parsley.
Recipe Tips
- How to get the richest flavor? The most important secret is the slow caramelization of the onions. This is a non-negotiable step. Cooking the onions gently over a low heat for a full 20-25 minutes is what transforms their sharp flavor into a deep, complex sweetness that forms the foundation of the entire soup.
- How to get a perfectly silky, not stringy, soup? For an ultra-silky, restaurant-quality finish that Gordon would approve of, pass the blended soup through a fine-mesh sieve. This will remove any small, un-blended fibrous bits of onion.
- Can I make this soup ahead of time? Absolutely! This soup is a perfect make-ahead dish. The flavor actually improves on the second day after the ingredients have had time to meld.
- How do you keep the cream from splitting? Always add the heavy cream at the very end, over the lowest possible heat. Never let a cream-based soup come to a rapid boil, as this can cause the dairy to curdle and separate.
What To Serve With White Onion Soup
This is a classic, elegant soup that is a wonderful starter or a light meal on its own. It is perfectly served with:
- A slice of crusty, warm bread or a cheesy crouton on top, similar to French onion soup.
- A simple grilled cheese sandwich for dipping.
- A sprinkle of crispy, fried shallots for a textural contrast.
How To Store White Onion Soup
- Refrigerate: Let the soup cool completely, then store it in an airtight container in the refrigerator for up to 4 days.
- Freeze: This soup freezes very well, especially if you freeze it before adding the cream. Let it cool completely, then transfer it to freezer-safe containers. It can be frozen for up to 3 months.
- Reheat: Reheat the soup gently in a saucepan over low heat, stirring frequently. Do not let it boil.

FAQs
What’s the difference between white and yellow onions for this soup?
White onions have a sharper, more pungent flavor when raw, but they cook down to a beautiful, milder sweetness than yellow onions, which makes them perfect for a soup where the onion is the star.
Can I make this soup dairy-free or vegan?
Yes, easily. To make it vegan, substitute the butter with an equal amount of olive oil, use a high-quality vegetable broth, and replace the heavy cream with a plant-based alternative like full-fat oat cream or cashew cream.
Why is my soup bland?
A bland soup is almost always the result of under-seasoning or not caramelizing the onions for long enough. Be patient with the onions, and don’t be shy with the salt and freshly ground pepper at the very end. Taste and adjust until the flavors are bold and balanced.
