Detailed Recipe Steps

Now that you have your ingredients gathered, let’s dive into the preparation of your Irresistibly Creamy Brussels Sprout Casserole. Follow these steps closely for the best results:

Preheat the Oven: Begin by preheating your oven to 375°F (190°C). This will ensure that the casserole cooks evenly.
Prepare the Brussels Sprouts: In a large mixing bowl, toss the halved Brussels sprouts with olive oil, salt, and pepper. Ensure they are evenly coated for optimal flavor.
Sauté the Brussels Sprouts: In a large skillet over medium heat, sauté the Brussels sprouts for about 5-7 minutes until they start to become tender and slightly golden. This step enhances their natural sweetness and adds depth to the flavor.
Make the Creamy Sauce: In a separate bowl, mix together the heavy cream, Parmesan cheese, mozzarella cheese, minced garlic, onion powder, garlic powder, and crushed red pepper flakes (if using). Stir until well combined, creating a luscious sauce.
Combine Ingredients: Add the sautéed Brussels sprouts to the creamy mixture, ensuring that they are well coated. This is where the magic happens—the sprouts soak up all that delicious sauce!
Transfer to Baking Dish: Pour the mixture into a greased 9×13 inch baking dish, spreading it evenly to ensure even cooking.
Prepare the Topping: In a small bowl, combine the breadcrumbs with melted butter. Mix until the breadcrumbs are evenly coated with the butter, then sprinkle this mixture evenly over the casserole to create a crispy topping.
Bake: Place the baking dish in the preheated oven and bake for 25-30 minutes, or until the top is golden brown and the casserole is bubbly. Keep an eye on it towards the end to avoid burning.
Garnish and Serve: Once out of the oven, let the casserole cool for a few minutes. Garnish with chopped parsley for a fresh pop of color and flavor before serving.
