Ingredients
Scale
For the Soup:
- 4 medium yellow onions, thinly sliced
- 3 tbsp unsalted butter
- 1 tbsp olive oil
- 1/2 tsp salt
- 1/4 tsp black pepper
- 1 tsp sugar
- 2 cloves garlic, minced
- 1 tbsp all-purpose flour
- 4 cups beef broth
- 1/2 cup heavy cream
- 1 tsp fresh thyme (or 1/2 tsp dried)
- 1 bay leaf
For the Bread Bowls:
- 4 small round bread boules, hollowed out
- 2 cups shredded Gruyère cheese (or Swiss or mozzarella)
Instructions
- Caramelize the onions: In a large pot, melt the butter and olive oil over medium heat. Add the thinly sliced onions, salt, black pepper, and sugar. Cook for 30 to 40 minutes, stirring frequently, until the onions are deeply golden brown and caramelized, releasing their natural sweetness.
- Add garlic and flour: Stir in the minced garlic and cook for 1 minute until fragrant. Then add the all-purpose flour and stir continuously for 2 minutes to slightly thicken the mixture and develop a subtle nutty flavor.
- Simmer the soup: Pour in the beef broth, add fresh thyme and the bay leaf. Bring the soup to a simmer and cook for 15 to 20 minutes to blend the flavors and allow the soup to thicken slightly.
- Add cream and adjust seasoning: Remove the bay leaf and stir in the heavy cream to create a rich, creamy texture. Taste and adjust seasoning with extra salt or pepper if desired.
- Prepare bread bowls: Preheat the oven to 375°F (190°C). Hollow out the small round bread boules, leaving enough bread thickness to hold the soup without leaking. Place the hollowed bread bowls on a baking sheet.
- Assemble and bake: Fill each bread bowl with the hot soup and top generously with shredded Gruyère cheese. Bake in the preheated oven for 10 to 15 minutes until the cheese fully melts and becomes bubbly. For a golden brown finish, broil the bread bowls for an additional 2 to 3 minutes.
- Serve: Garnish the baked French onion soup bread bowls with a sprinkle of fresh thyme leaves and a crack of black pepper just before serving. Serve hot for best flavor and texture.
Notes
- Use a heavy-bottomed pot to caramelize onions evenly without burning.
- To save time, onions can be pre-caramelized earlier and reheated before assembling soup.
- Gruyère cheese provides classic flavor, but Swiss or mozzarella are good substitutes.
- For a vegetarian version, replace beef broth with vegetable broth.
- Serve immediately after baking to enjoy the melty cheese and crispy bread bowls.
