French onion soup 🧅🍲
Ingredients
4 large onions, thinly sliced
3 tbsp unsalted butter
1 tbsp olive oil
2 garlic cloves, minced
1 tbsp all-purpose flour
1/2 cup dry white wine
4 cups beef stock (or chicken stock for a lighter flavor)
1 bay leaf
1 tsp fresh thyme leaves
Salt and pepper, to taste
4 slices baguette or crusty bread
1 cup grated Gruyère cheese
1 pack sliced provolone cheese
Instructions
Caramelize the Onions:
Heat the butter and oil: In a large pot or Dutch oven, melt the butter with olive oil over medium heat.
Cook the onions: Add the sliced onions and a pinch of salt. Cook for 25-30 minutes, stirring frequently, until the onions are golden brown and caramelized. Reduce the heat if they start to burn.
Build the Soup:
Add the garlic and flour: Stir in the minced garlic and cook for 1 minute. Sprinkle in the flour, stirring constantly, and cook for another minute to remove the raw taste.
Deglaze with wine: Pour in the white wine, scraping up any browned bits from the bottom of the pot. Simmer until the wine reduces by half.
Add the stock and herbs: Stir in the beef stock, bay leaf, and thyme. Bring to a gentle boil, then reduce the heat and simmer for 15-20 minutes. Adjust seasoning with salt and pepper.
Prepare the Topping:
Toast the bread: Lightly toast the baguette slices under the broiler or in a toaster until golden brown.
Top with cheese: Sprinkle the Gruyère cheese over the bread slices and broil until melted and bubbly.
Serve the Soup:
Remove the bay leaf from the soup.
Ladle the soup into oven-safe bowls, place a cheesy bread slice on top, top with 2 slices of provolone cheese and broil for 2-3 minutes until golden.
French onion soup is a traditional French dish known for its rich, deep flavors and satisfying texture. The key to making an authentic French onion soup lies in the slow caramelization of onions, which transforms their natural sweetness and creates a rich base for the broth. Using a mixture of unsalted butter and olive oil helps achieve the perfect balance of flavor and prevents the onions from burning during the long cooking process. The addition of garlic and flour not only enhances the overall taste but also thickens the soup, giving it a velvety texture without overpowering the natural flavors of the onions. Deglazing the pot with dry white wine lifts the caramelized bits off the pan and infuses the soup with subtle acidity and complexity. Choosing beef stock provides a robust and hearty foundation, but chicken stock can be a lighter alternative to suit different preferences. Fresh thyme and a bay leaf enrich the broth with aromatic herbal notes, which complement the sweetness of the caramelized onions. A critical element that elevates French onion soup is the cheese-topped bread. French-style baguette slices toasted until golden create a perfect base for the Gruyère and provolone cheese. Gruyère is traditionally used due to its excellent melting qualities and slightly nutty flavor, while provolone adds a creamy, mild contrast. Broiling the assembled soup until the cheese is melted and bubbly creates a delightful crust that enhances both texture and taste. For an unforgettable dining experience, oven-safe bowls are recommended when serving. This method allows finishing touches like broiling the cheese topping directly on the soup, providing the characteristic gratinéed surface that defines classic French onion soup. To optimize this recipe at home, consider using quality ingredients such as fresh onions, good-quality white wine, and authentic French bread. Patience in caramelizing the onions and carefully balancing seasoning are essential to achieve a flavorful and well-rounded soup. French onion soup is a perfect comfort food for fall and winter, warming you up with every spoonful. Complement it with a fresh green salad or a glass of your favorite wine for a complete meal. Moreover, it's a versatile dish allowing customization, such as using vegetarian stock or adding herbs like rosemary for extra fragrance. This recipe not only brings out the traditional flavors of French cuisine but also fits well with contemporary tastes, making it a beloved classic worldwide.
