Ingredients Needed
- 4 large white onions, thinly sliced
- 2 tablespoons unsalted butter
- 2 tablespoons olive oil
- 4 cloves garlic, minced
- 4 cups vegetable or chicken broth
- 1 cup heavy cream
- 1 teaspoon dried thyme
- 1 teaspoon dried oregano
- 1 teaspoon dried rosemary
- Salt and pepper, to taste
- Fresh chives, chopped (for garnish)
- Fresh parsley, chopped (for garnish)
- Crusty bread or croutons (optional, for serving)
How To Make Gordon Ramsay White Onion Soup
- Caramelize the Onions: In a large pot, heat the butter and olive oil over medium heat. Add the sliced onions and cook for 20-25 minutes, stirring occasionally, until they turn soft, golden brown, and slightly jammy. Slow cooking enhances their natural sweetness—don’t rush this step!
- Sauté the Garlic: Stir in the minced garlic and cook for 2-3 minutes until fragrant. Be careful not to brown it too much, as this can make the soup bitter.
- Simmer with Broth: Pour in the vegetable or chicken broth and bring the mixture to a gentle simmer. Let it cook for 15-20 minutes, allowing the flavors to meld beautifully.
- Blend Until Smooth: Use an immersion blender to puree the soup until silky and smooth. If using a countertop blender, blend in batches and vent the lid slightly to prevent steam buildup. Return the soup to the pot over low heat.
- Add Cream and Herbs: Stir in the heavy cream, thyme, oregano, and rosemary. Season with salt and pepper to taste, adjusting as needed. Let it warm for a few minutes, but avoid boiling.
- Serve and Garnish: Ladle the soup into bowls and top with fresh chives and parsley. Serve with crusty bread or croutons for extra texture.

Recipe Tips
- Caramelization is key! Cook the onions slowly over medium heat for the best depth of flavor.
- Want a lighter version? Swap heavy cream for half-and-half or whole milk.
- For a richer taste, use chicken broth instead of vegetable broth.
- Add a cheesy twist: Sprinkle-grated Parmesan or Gruyère on top before serving.
- Low-carb option: Skip the croutons and add an extra touch of cream or butter for a thicker texture.
How To Store & Reheat Leftovers
Storing in the Fridge: Let the soup cool completely, then transfer it to an airtight container and refrigerate for up to 4 days.
Freezing: Pour the cooled soup into freezer-safe containers, leaving some space for expansion. Freeze for up to 3 months.
Reheating: Warm the soup in a pot over low heat, stirring occasionally. If it’s too thick, add a splash of broth or cream to loosen the texture.
