Ingredients
- 4 cups fresh broccoli florets: The star of the dish, providing nutrients and a beautiful green color.
- 2 tablespoons butter: For sautéing and adding richness to the cheese sauce.
- 1/4 cup onion, finely chopped: Adds flavor and depth to the dish.
- 2 cloves garlic, minced: For aromatic flavor.
- 2 cups shredded cheese (cheddar, mozzarella, or a blend): The base of the creamy sauce; feel free to mix your favorites.
- 1 cup milk: Helps create a creamy consistency.
- 2 tablespoons all-purpose flour: To thicken the sauce.
- 1 teaspoon Dijon mustard (optional): Adds a hint of tanginess.
- Salt and pepper to taste: Essential for seasoning.
- 1/2 cup breadcrumbs: For a crunchy topping.
- 1/4 cup grated Parmesan cheese: To enhance the flavor of the topping.
Instructions
STEP 1: PREHEAT THE OVEN
Start by preheating your oven to 375°F (190°C). This ensures that your casserole will bake evenly and develop a lovely golden crust.
STEP 2: COOK THE BROCCOLI
Bring a pot of salted water to a boil. Add the broccoli florets and blanch them for about 2-3 minutes until bright green and slightly tender. Drain the broccoli and plunge it into ice water to stop the cooking process. This helps maintain the vibrant color and crisp texture.
STEP 3: MAKE THE CHEESE SAUCE
In a medium saucepan over medium heat, melt the butter. Add the chopped onion and sauté until translucent, about 3-4 minutes. Stir in the minced garlic and cook for an additional minute until fragrant.
Next, whisk in the flour to create a roux, cooking for about 1 minute until it’s lightly golden. Gradually pour in the milk while continuously whisking to prevent lumps. Cook the mixture, stirring frequently, until it thickens and coats the back of a spoon, about 5-7 minutes.
Once thickened, remove the saucepan from the heat and stir in 1 1/2 cups of shredded cheese and Dijon mustard (if using). Mix until the cheese is melted and the sauce is smooth. Season with salt and pepper to taste.
STEP 4: ASSEMBLE THE CASSEROLE
In a large mixing bowl, combine the blanched broccoli and cheese sauce, mixing until the broccoli is well-coated. Transfer the mixture to a greased 9×13-inch baking dish, spreading it evenly.
STEP 5: ADD THE TOPPING
In a small bowl, combine the breadcrumbs, remaining 1/2 cup of shredded cheese, and grated Parmesan cheese. Sprinkle this mixture evenly over the broccoli and cheese sauce in the baking dish. This topping will create a crispy, golden crust as it bakes.
STEP 6: BAKE
Place the baking dish in the preheated oven and bake for 25-30 minutes, or until the topping is golden brown and the casserole is bubbly. Keep an eye on it to ensure it doesn’t over-brown; you can cover it with foil if necessary.
STEP 7: SERVE
Remove the casserole from the oven and let it cool for a few minutes before serving. This allows the sauce to set slightly, making it easier to serve. Enjoy this cheesy delight as a perfect side dish for your holiday meal!
