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 butter and olive oil over medium heat. Add thinly sliced onions, salt, pepper, and sugar. Cook for 30–40 minutes, stirring frequently, until the onions are deeply golden and caramelized, developing intense flavor.
- Add garlic and flour: Stir in the minced garlic and cook for 1 minute until fragrant. Sprinkle in the all-purpose flour and stir continuously for 2 minutes to slightly thicken the mixture and create a roux base.
- Simmer the soup: Pour in the beef broth along with the fresh thyme and bay leaf. Bring to a simmer and let it cook for 15–20 minutes to allow the flavors to meld and the soup to develop depth.
- Add cream and season: Remove and discard the bay leaf. Stir in the heavy cream, then taste and adjust seasoning with additional salt or pepper as needed for a rich and creamy finish.
- Prepare the bread bowls: Preheat the oven to 375°F (190°C). Hollow out the small round bread boules carefully, leaving a sturdy shell to hold the soup. Place these bowls on a baking sheet ready for assembly.
- Assemble and bake: Fill each hollowed bread bowl with the creamy onion soup. Generously top each with shredded Gruyère cheese. Bake for 10–15 minutes until the cheese is melted and bubbly. Optionally, broil for an additional 2–3 minutes to achieve a golden, slightly crispy cheese crust.
- Serve: Garnish with fresh thyme sprigs and freshly cracked black pepper before serving to enhance aroma and presentation. Enjoy the creamy, cheesy soup served in its edible bread bowl.
Notes
- For a vegetarian option, substitute beef broth with vegetable broth.
- Adjust the caramelization time for onions if you prefer a sweeter or less intense flavor.
- Use sturdy bread like sourdough boules which hold up well to the hot soup.
- Gruyère is traditional for French onion soup, but Swiss or mozzarella cheeses work well too.
- Careful when broiling to avoid burning the cheese; watch it closely.
