Indulge in the classic comfort of **French Onion Soup**, a timeless dish brimming with deep, caramelized onion flavor and topped with a golden, bubbly layer of Gruyere cheese. This recipe starts by slow-cooking yellow onions in a blend of unsalted butter and olive oil until theyβre perfectly caramelized, enhanced with a touch of sugar for added richness. Deglazed with dry white wine and simmered in a flavorful beef broth infused with fresh thyme and a bay leaf, this soup achieves a beautifully complex taste. Each serving is crowned with a toasted baguette slice generously layered with melted Gruyere and broiled to perfection. Ideal for cozy weeknight dinners or special occasions, this French Onion Soup is a hearty and satisfying dish, best served piping hot with extra crusty bread for dipping.

Peel the onions and slice them thinly into half-moons.
In a large pot or Dutch oven, heat the butter and olive oil over medium heat until melted.
Add the sliced onions to the pot and cook, stirring occasionally, for 25-30 minutes until they are deeply caramelized and golden brown. Sprinkle the sugar over the onions halfway through cooking to help them caramelize.
Stir in the minced garlic and cook for 1-2 minutes until fragrant.
Deglaze the pot by pouring in the white wine, scraping the bottom of the pot to release any stuck bits. Simmer for 2-3 minutes until the alcohol evaporates.
Add the beef broth, bay leaf, and thyme sprigs to the pot. Bring the mixture to a boil, then reduce the heat to low and simmer for 20-25 minutes. Season the soup with salt and black pepper to taste.
While the soup simmers, preheat the oven broiler. Place the baguette slices on a baking sheet and toast them under the broiler for 1-2 minutes per side until golden brown.
Once toasted, top the baguette slices with grated Gruyere cheese. Return them to the oven and broil for another 1-2 minutes until the cheese is melted and bubbly.
Remove the thyme sprigs and bay leaf from the soup. Ladle the soup into individual oven-safe bowls.
Place a cheese-topped baguette slice on top of each bowl of soup. Optionally, sprinkle additional cheese on top.
Place the soup bowls under the broiler for 2-3 minutes until the cheese is melted and golden brown. Serve immediately with a side of warm, crusty bread if desired.
