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 vegetable or chicken broth
• 1 cup heavy cream
• 1 tsp dried thyme
• 1 tsp dried oregano
• 1 tsp dried rosemary
• Salt and pepper, to taste
• Fresh chives and parsley, for garnish
• Crusty bread or croutons, for serving (optional)

How To Make Gordon Ramsay White Onion Soup

1. Caramelize the onions: In a large pot or Dutch oven, heat the butter and olive oil over medium-low heat. Add the thinly sliced onions and cook slowly for 20–25 minutes, stirring occasionally, until they are deeply golden, soft, and have a jammy consistency.
2. Sauté the garlic: Stir in the minced garlic and cook for another 2–3 minutes until it becomes fragrant. Be careful not to let it burn.
3. Simmer the soup base: Pour the broth into the pot, scraping up any browned bits from the bottom. Bring the mixture to a boil, then reduce the heat and let it simmer for 15–20 minutes to allow the flavors to meld together.
4. Blend the soup: Use an immersion blender to carefully puree the soup directly in the pot until it is completely smooth and silky. Alternatively, you can transfer the soup in batches to a stand blender and blend until smooth.
5. Finish with cream and herbs: Return the soup to the pot over low heat. Stir in the heavy cream, dried thyme, oregano, and rosemary. Warm everything through gently, but do not allow it to boil. Season to taste with salt and pepper.
6. Garnish and serve: Ladle the hot soup into bowls. Top with fresh chopped chives and parsley, and serve immediately with crusty bread or croutons on the side.

Recipe Tips

• Patience is Key: The most important step is slowly caramelizing the onions. Don’t rush this process. Cooking them low and slow for 20-25 minutes develops a deep, jammy sweetness that is the foundation of the soup’s flavor.
• Avoid Boiling the Cream: After adding the heavy cream, only warm the soup gently. Bringing it to a boil can cause the cream to curdle or separate, which would ruin the soup’s silky, luxurious texture.
• Use a Quality Broth: The quality of your broth significantly impacts the final taste. Use a flavorful, low-sodium vegetable or chicken broth. A watery, bland stock will result in a less satisfying soup.
• Blend for a Silky Finish: For that truly luxurious, restaurant-quality feel, blend the soup until it is completely smooth and free of lumps. An immersion blender makes this easy, but a stand blender will also work perfectly.

What To Serve White Onion Soup

This elegant soup is best served with something to complement its creamy texture. A slice of crusty baguette or sourdough bread is perfect for dipping. For extra crunch and flavor, top each bowl with homemade garlic croutons or cheesy Gruyère toasts, similar to a classic French onion soup. A simple green salad with a sharp vinaigrette can also be served alongside to cut through the richness.

How To Store White Onion Soup Leftovers

• Refrigerate: Allow the soup to cool completely before storing it in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stovetop over low heat, stirring frequently.
• Freeze: It is best to freeze this soup before adding the cream, as dairy can separate and become grainy when thawed. Let the blended soup base cool, freeze it for up to 3 months, then thaw, reheat, and stir in the cream and herbs before serving.

FAQs

• Can I use yellow or red onions instead of white onions? Yes, but the flavor and color will be different. White onions are specifically used for their mildness and sweetness. Yellow onions are a good substitute, though slightly more pungent. Red onions will give the soup a different flavor and a purplish color.
• How can I make this soup dairy-free? To make a dairy-free version, use only olive oil (omitting the butter) and substitute the heavy cream with a full-fat, unsweetened plant-based alternative like oat cream, cashew cream, or coconut cream for a similar rich texture.
• Why is my soup not sweet? The sweetness comes from properly caramelizing the onions. If your soup isn’t sweet, the onions were likely cooked too quickly or not long enough. They need at least 20 minutes over low to medium heat to break down their natural sugars.
• Can I make this soup ahead of time? Absolutely. You can prepare the soup up to the point right before adding the cream. Let the blended soup base cool and store it in the refrigerator for up to two days. When you’re ready to serve, gently reheat it on the stove and stir in the cream and herbs.
