Indulge in culinary excellence with this exquisite recipe! Witnessed at a neighborhood gathering, this dish captivated all with its irresistible charm.
Ingredients:
- 3 tablespoons of unsalted butter
- 3 large sweet onions, thinly sliced
- 2 cloves of garlic, minced
- Salt and pepper to taste
- 1 teaspoon of thyme (fresh or dried)
- 2 tablespoons of all-purpose flour
- 1/2 cup of dry white wine
- 2 cups of beef broth
- 1 cup of chicken broth
- 6 slices of day-old French bread or baguette, toasted
- 1 1/2 cups of grated Gruyère cheese
- 1/2 cup of grated Parmesan cheese
- 1/4 cup of fresh parsley, chopped (for garnish)
- Cooking spray
Directions:
- Preheat your oven to 400°F (200°C). Coat a 9×13 inch baking dish with cooking spray.
- In a large pan over medium heat, melt the butter. Add onions and cook until they are tender, sweet, and golden brown, which usually takes about 15 minutes. Stir in garlic, salt, pepper, and thyme, cooking for an additional minute.
- Sprinkle flour over the onions, stirring continuously, then pour in the wine. Allow it to simmer until the liquid reduces slightly. Add both broths and simmer for an additional 10 minutes.
- Pour half of the onion mixture into the prepared baking dish. Layer half of the toasted bread slices, followed by half of the Gruyère and Parmesan cheese. Repeat with the remaining ingredients.
- Bake uncovered for 20-25 minutes, or until the cheese is golden and bubbly at the edges.
- Allow the casserole to rest for a few minutes, then garnish with fresh parsley before serving.
