Gordon Ramsay French Onion Soup Recipe – Ingredients and Preparation

Ingredients List

Save

For the Soup Base:

• 6 large yellow onions (about 3 pounds), thinly sliced
• 3 tablespoons unsalted butter
• 2 tablespoons olive oil
• 1 teaspoon granulated sugar (helps with caramelization)
• 2 cloves garlic, minced
• 1 tablespoon all-purpose flour
• 1/4 cup good-quality brandy or cognac
• 1/2 cup dry white wine
• 8 cups high-quality beef stock
• 2 bay leaves
• 4 sprigs fresh thyme, tied with kitchen string
• Salt and freshly ground black pepper to taste

For the Topping:

• 1 baguette, sliced into 1-inch rounds
• 2 tablespoons olive oil
• 2 cloves garlic, halved
• 2 cups Gruyère cheese, grated
• 1/2 cup Parmesan cheese, grated

Substitutions:

• Vegetarian Option: Replace beef stock with mushroom or vegetable stock, and add 1 tablespoon soy sauce for umami depth
• Gluten-Free Option: Use gluten-free flour and gluten-free bread for the topping
• Dairy-Free Option: Substitute olive oil for butter and use a dairy-free cheese alternative

Step-by-Step Instructions

1. Prepare the onions: Peel and thinly slice the onions into half-rings. For the most authentic result, slice them evenly using a sharp knife rather than a food processor. Chef’s Tip: Chill onions in the refrigerator for 30 minutes before slicing to reduce eye irritation.
2. Begin the caramelization process: In a large, heavy-bottomed pot, heat the butter and olive oil over medium heat. Add the sliced onions and toss to coat evenly with the fat. Chef’s Tip: Use a Dutch oven if available – the even heat distribution will help caramelize the onions more consistently.
3. Slowly caramelize: Reduce heat to medium-low and cook the onions, stirring occasionally, for 45-60 minutes. This is where patience is crucial – rushing this step will compromise the flavor foundation of your soup. Chef’s Tip: Add the sugar after about 20 minutes to help accelerate the caramelization process without burning.
4. Deepen the flavor: When onions are deeply golden and reduced to about 1/4 of their original volume, add minced garlic and cook for 1 minute until fragrant.
5. Create the roux: Sprinkle flour over the caramelized onions and stir continuously for 2-3 minutes to cook out the raw flour taste. Chef’s Tip: Ensure the flour is fully incorporated with no lumps before proceeding.
6. Deglaze the pot: Add the brandy and white wine, stirring vigorously to scrape up any flavorful bits stuck to the bottom of the pot. Let it reduce by half, about 3-4 minutes.
7. Add the stock and herbs: Pour in the beef stock, add bay leaves and thyme bundle. Bring to a gentle simmer.
8. Simmer: Reduce heat to low and simmer, partially covered, for 30-40 minutes to allow flavors to meld. Season with salt and pepper to taste. Chef’s Tip: Avoid stirring too frequently during simmering as this can break down the onions too much.
9. Prepare the bread topping: Preheat your oven to broil. Brush baguette slices with olive oil on both sides, then rub with cut garlic cloves. Toast in the oven until golden brown on both sides.
10. Assemble for serving: Ladle the hot soup into oven-safe bowls. Place a toasted baguette slice on top of each bowl of soup, then generously sprinkle with Gruyère and Parmesan cheeses.
11. Broil: Place the bowls on a baking sheet and broil until the cheese is melted, bubbly, and slightly browned, about 2-3 minutes.

Chef’s Tip: Watch the broiling process carefully – the difference between perfectly golden and burnt cheese happens in seconds!

12. Serve: Carefully remove from the oven (the bowls will be extremely hot) and allow to cool slightly before serving.

Notes and Tips

Storage: This soup actually improves with time as flavors continue to develop. Store cooled soup in an airtight container in the refrigerator for up to 3 days. Store the bread and cheese toppings separately.

Reheating: Reheat gently on the stovetop until hot, then proceed with the bread and cheese topping as directed.

Make-ahead instructions: The soup base can be made up to 2 days in advance and stored in the refrigerator. You can also freeze the soup (without bread and cheese) for up to 3 months. Thaw overnight in the refrigerator before reheating.

Serving suggestions: Pair with a simple green salad dressed with Dijon vinaigrette and a glass of the same dry white wine used in the recipe for a complete French bistro experience.

Gordon Ramsay French Onion Soup Recipe – History and Cultural Significance

French onion soup, or “soupe à l’oignon” as it’s known in France, has humble origins that trace back to Roman times. However, the version we recognize today became popular in 18th-century France. It began as a peasant dish, making use of inexpensive, readily available ingredients – primarily onions – to create a hearty, filling meal.

The soup gained particular fame in Paris, where it was traditionally served in the early morning at Les Halles, the central market district. Market workers and late-night revelers would enjoy this restorative soup after long hours of work or play. The combination of sweet caramelized onions in rich broth, topped with bread and melted cheese, provided both comfort and sustenance.

Gordon Ramsay’s take on this classic dish respects its historical roots while incorporating his signature attention to technique and flavor building. His method of slowly caramelizing the onions for up to an hour is a nod to traditional French cooking principles, where patience and precision are valued over speed.

Interestingly, similar onion soup variations exist in other cuisines. In Spain, you’ll find sopa de cebolla, often flavored with sherry instead of white wine. Italian cipollata includes pancetta and sometimes tomatoes. Even in England, they have their version called “Brown Windsor Soup” which sometimes incorporates onions as a base flavor, though it typically includes meat as well.

What makes the French version – and particularly Ramsay’s interpretation – stand out is the dedication to properly caramelizing the onions until they achieve that perfect balance of sweetness and depth, creating the robust foundation that defines this classic soup.

Gordon Ramsay French Onion Soup Recipe – Creative Variations

Classic With a Twist: White Wine and Herb Infusion

This variation enhances Gordon Ramsay’s base recipe with additional aromatics:

• Add 1 tablespoon of herbs de Provence to the onions during the last 10 minutes of caramelization
• Use a dry Chardonnay instead of a generic white wine
• Finish with a sprinkle of fresh chives before serving
• Consider adding a parmesan rind during simmering (remove before serving)

This version maintains the essence of the classic recipe while adding subtle complexity through the herb infusion. The parmesan rind adds an extra dimension of umami that complements the sweet onions beautifully.

Vegetarian French Onion Soup

Transform this traditionally beef-based soup into a vegetarian delight:

• Replace beef stock with mushroom stock (preferably homemade from dried porcini and fresh cremini mushrooms)
• Add 1 tablespoon soy sauce and 1 teaspoon miso paste for umami depth
• Include 2 tablespoons of nutritional yeast in the broth
• Use a combination of yellow and red onions for more complex flavor
• Top with a vegetarian cheese alternative or traditional Gruyère if lacto-vegetarian

This version sacrifices none of the depth and satisfaction of the original while making it accessible to those following a vegetarian diet. The combination of mushroom stock, soy sauce, and miso creates a remarkably rich base that might even fool devoted meat-eaters.

Low-Carb French Onion Soup Adaptation

For those watching their carbohydrate intake:

• Reduce onions to 4 instead of 6 (onions contain natural sugars)
• Skip the sugar in the caramelization process (it will take longer, but still caramelize)
• Replace the flour with 1 teaspoon of xanthan gum to thicken
• Use thinly sliced roasted portobello mushroom caps instead of bread for topping
• Keep the cheese topping as is (cheese is naturally low in carbs)

This variation reduces the carbohydrate content while maintaining the essence of French onion soup. The portobello “crouton” provides a meaty texture and umami flavor that complements the soup wonderfully.

Gordon Ramsay French Onion Soup Recipe – Frequently Asked Questions

Can I freeze Gordon Ramsay’s French onion soup?

Yes, you can freeze the soup base (without the bread and cheese topping) for up to 3 months. Allow it to cool completely before transferring to freezer-safe containers, leaving some headspace for expansion. Thaw overnight in the refrigerator, then reheat gently on the stovetop. Prepare the bread and cheese topping fresh when you’re ready to serve.

What can I substitute for Gruyère cheese?

While Gruyère is traditional for authentic French onion soup, you can substitute:

• Swiss cheese – The most common and readily available alternative
• Emmental – Another Swiss cheese with good melting properties
• Fontina – Offers a nice mild flavor and excellent meltability
• Provolone – A bit sharper but still works well
• Jarlsberg – A Norwegian cheese with a milder flavor similar to Swiss

For best results, you might want to blend your substitute cheese with a bit of Parmesan to help replicate the complexity of Gruyère.

How long does it take to caramelize onions properly for French onion soup?

Properly caramelizing onions for Gordon Ramsay’s French onion soup recipe takes 45-60 minutes over medium-low heat. This is not a step you can rush, as the slow cooking process is what develops the deep, sweet flavor that forms the foundation of the soup. If you try to speed up the process by using higher heat, you’ll likely end up with burnt rather than caramelized onions. The time investment is absolutely worth it for the rich flavor it creates.

Is Gordon Ramsay’s French onion soup gluten-free?

The traditional recipe is not gluten-free due to the flour used to thicken the soup and the baguette topping. However, it can easily be adapted:

• Substitute the all-purpose flour with a gluten-free flour blend or cornstarch
• Use gluten-free bread for the topping
• Ensure your beef stock is certified gluten-free (some commercial stocks contain gluten)

With these simple substitutions, you can enjoy a gluten-free version that maintains the authentic flavor profile.

What type of onions work best for Gordon Ramsay’s French onion soup?

Yellow onions are the best choice for French onion soup because they have the perfect balance of sweetness and flavor complexity when caramelized. While sweet onions like Vidalia or Walla Walla may seem like a good choice, they can become too sweet when caramelized. Red onions can work but will give the soup a different color, and white onions generally lack the depth of flavor needed. For the most authentic result, stick with yellow onions as Gordon Ramsay recommends.
