Ingredients
- 6 large yellow onions, thinly sliced
- 4 tbsp unsalted butter
- 2 tbsp olive oil
- 2 garlic cloves, minced
- 1 tsp granulated sugar (helps with caramelization)

- Assemble soup bowls: Ladle the hot soup into oven-safe bowls.Place 2-3 baguette slices on top, then cover generously with a mixture of Gruyere and Emmental cheeses.
- Bake under the broiler: Set the oven broiler to high. Place the bowls on a baking sheet and broil for 3-5 minutes, watching carefully until the cheese melts into a bubbling, golden crust with crispy edges.
- Garnish and serve: Sprinkle freshly chopped parsley and crack some black pepper over the cheese crust. Serve immediately for the ultimate comforting experience.
Tips for Success: Elevate Your Indulge in Rich, Cheesy French Onion Soup Gratinee Experience
- Onion choice: Yellow onions offer ideal sweetness, but combining with a few sweet red onions can enhance complexity.
- Controlling caramelization: Avoid rushing the process by turning the heat too high. Low and slow cooking preserves texture and prevents burning.
- Broth selection: Use a high-quality beef broth for authentic depth or a richly flavored vegetable broth for a lighter,vegetarian-kind option.
- Cheese pairing: Gruyere’s nutty tang is paramount. mixing in Emmental grants creamier meltability and an appealing stretchiness.
- Make-ahead: Onions can be caramelized up to 3 days prior and refrigerated. Reheat gently before assembling the soup.
- Crust perfection: for a thicker crust, brush toasted baguette slices lightly with olive oil before topping with cheese.
