I'm a rich and savory blend of caramelized onions, pungent garlic, and creamy cheese that will fill your kitchen with warmth. My buttery, flaky crust gives way to a tender, comforting center.
Ingredients
- 3 large onions, thinly sliced
- 4 cloves garlic, peeled and minced
- 2 tablespoons unsalted butter, softened
- 1/2 cup all-purpose flour
- 2 cups grated cheddar cheese
- 1 cup grated mozzarella cheese
- 1/2 cup heavy cream
- 1 teaspoon salt
- 1/4 teaspoon black pepper
- 2 cups crushed crackers, for topping
Method
- 1Preheat the oven to 375°F, then butter a 9x13-inch baking dish and set it aside.
- 2In a large skillet, cook the sliced onions over medium-low heat, stirring occasionally, until they are deeply golden and fragrant, about 30 minutes.
- 3Add the minced garlic to the skillet and cook for 1-2 minutes, stirring constantly, until fragrant.
- 4In a medium saucepan, whisk together the flour and heavy cream, then bring the mixture to a simmer over medium heat, whisking constantly, until it thickens, about 5 minutes.
- 5Remove the sauce from the heat and stir in the cheddar and mozzarella cheese until melted and smooth, then season with salt and pepper to taste.
- 6Combine the cooked onions and garlic, cheese sauce, and crushed crackers in the prepared baking dish, then cover the dish with aluminum foil and bake for 25 minutes.
- 7Remove the foil and continue baking for an additional 10-15 minutes, until the top is golden brown and the casserole is hot and bubbly.
- 8Let the casserole rest for 10-15 minutes before serving, until the cheese has set and the onions have cooled slightly.
