How to Make Broccoli Casserole

Step 1: Preparing the Broccoli

  • Preheat your oven to 375°F (190°C).
  • Wash the broccoli thoroughly and cut it into bite-sized florets.
  • In a large pot of boiling water, blanch the broccoli florets for 1 minute. This will soften them slightly and make them more vibrant in color. Drain the broccoli and set aside.

Step 2: Creating the Creamy Cheese Sauce

  • In a large saucepan, melt the unsalted butter over medium heat.
  • Add the minced garlic and sauté for about 1 minute until it becomes fragrant.
  • Reduce the heat to low and add the cream cheese, stirring continuously until it’s completely melted and smooth.
  • Pour in the heavy whipping cream and continue stirring until the mixture is well combined.
  • Add the grated cheddar and mozzarella cheese into the sauce, allowing it to melt and create a rich, creamy texture.
  • Stir in the yellow mustard, dried basil, sea salt, and black pepper. The mustard will add a delightful tang to the sauce, while the basil and seasoning will enhance the overall flavor.

Step 3: Assembling the Casserole

  • Take a baking dish and lightly grease it with butter or cooking spray.
  • Arrange the blanched broccoli florets evenly in the baking dish.
  • Pour the creamy cheese sauce over the broccoli, ensuring it’s distributed evenly and coats the florets thoroughly.

Step 4: Baking the Casserole

  • Place the baking dish in the preheated oven and bake for 20-25 minutes until the casserole is bubbling and the top is golden brown.
  • Once the casserole is cooked to perfection, remove it from the oven and let it cool slightly before serving.

Step 5: Serving and Enjoying

  • Serve the Cheesy Broccoli Casserole hot and garnish it with some additional grated cheddar and a sprinkle of dried basil for an extra touch of elegance.

This dish can be a delightful side to your main course or even a comforting standalone meal.
