Instructions
Let’s dive into the steps to create this flavorful masterpiece:
Preheat Your Oven: Start by preheating your oven to 375°F (190°C). This ensures that the casserole bakes evenly and develops that golden, crispy top.
Cook the Sausage: In a large skillet, cook the sausage over medium heat, breaking it apart with a spoon as it cooks. Once browned and fully cooked, remove it from the skillet and set it aside.
Prepare the Brussels Sprouts: While the sausage is cooking, trim and halve the Brussels sprouts. Sauté them in the same skillet with a bit of olive oil until they’re golden and slightly crispy, about 5-7 minutes.
Make the Creamy Sauce: In the same skillet, add the garlic and onions, and cook until fragrant and softened, about 2 minutes. Stir in the cream and cook for a few more minutes until the sauce thickens slightly. Season with salt and pepper to taste.
Assemble the Casserole: In a large baking dish, layer the cooked sausage, sautéed Brussels sprouts, and creamy sauce. Top it with shredded cheese.
Bake to Perfection: Pop the casserole into the oven and bake for 20-25 minutes, or until the cheese is melted and bubbly, and the top is golden brown.
Finishing Touches: Once the casserole is out of the oven, let it cool for a few minutes. This helps the flavors settle and makes it easier to serve.
Serve and Enjoy: Serve warm, and enjoy this comforting casserole on its own or with a side of your favorite vegetables or salad.
