French Onion Soup Casserole
Servings: 6 to 8
3 tablespoons unsalted butter
3 large sweet onions, thinly sliced
2 cloves garlic, minced
Salt and pepper to taste
1 teaspoon thyme (fresh or dried)
2 tablespoons all-purpose flour
1/2 cup dry white wine
2 cups beef broth
1 cup chicken broth
6 slices day-old French bread or baguette, toasted
1 1/2 cups grated Gruyère cheese
1/2 cup grated Parmesan cheese
1/4 cup fresh parsley, chopped (for garnish)
Preheat the oven to 400°F (200°C). Spray a 9×13 inch baking dish with cooking spray.
Melt butter in a large pan over medium heat. Add onions and cook until soft, sweet, and golden brown (about 15 minutes). Add garlic, salt, pepper, and thyme; cook for 1 more minute.
Sprinkle flour over the onions, cook for a couple of minutes, then pour in the wine. Let it simmer until the liquid reduces slightly. Add both broths and bring to a simmer for 10 minutes.
Pour half the onion mixture into the baking dish. Layer half the toasted bread slices, then sprinkle with half of the Gruyère and Parmesan. Repeat with the remaining ingredients.
Bake uncovered for 20-25 minutes, or until the cheese is bubbly and browned at the edges.
Let it rest for a few minutes, then garnish with fresh parsley before serving.
