Step‑by‑Step Instructions for Cheesy Brussels Sprouts Casserole

Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). This ensures that your Cheesy Brussels Sprouts Casserole cooks evenly and achieves a beautifully golden top. While the oven warms up, gather all your ingredients and equipment, ensuring you have a large skillet and a greased baking dish ready for the casserole.

Step 2: Melt the Butter
In a large skillet over medium heat, melt 2 tablespoons of butter until it starts to sizzle gently. This will add richness to your casserole. As the butter melts, keep an eye on it to prevent burning, creating a lovely base for sautéing the shallots and garlic, which will enhance the flavor of the dish.

Step 3: Sauté the Aromatics
Add 1 finely chopped shallot and 2 minced garlic cloves to the skillet. Sauté them together for about 30 seconds or until fragrant, stirring constantly to avoid browning. You’ll know they’re done when the shallot becomes translucent and aromatic, filling your kitchen with a savory fragrance that teases the taste buds.

Step 4: Cook the Brussels Sprouts
Next, toss in the halved Brussels sprouts and cook for approximately 10 minutes, stirring occasionally. Watch for the sprouts to turn a vibrant green and become slightly tender; they should still have a bit of crunch. Season this mixture with salt, pepper, cayenne pepper, and mustard powder to elevate the flavors of your Cheesy Brussels Sprouts Casserole.

Step 5: Add the Cream
Pour in 1 cup of heavy cream, stirring well to combine all the ingredients. The cream will create a luscious, velvety texture, helping to bring the casserole together. Allow the mixture to heat through for about 2–3 minutes, just until it’s steaming but not boiling, which will keep the cream from curdling.

Step 6: Transfer to Baking Dish
Carefully transfer the Brussels sprouts mixture into a greased baking dish, spreading it out evenly. This will ensure every bite of your Cheesy Brussels Sprouts Casserole is packed with flavor. Make sure to leave enough room for the toppings that will smother the top as they bake to perfection.

Step 7: Top with Cheese and Bacon
Sprinkle crumbled cooked bacon evenly across the top of the mixture, followed by generous layers of shredded sharp white cheddar and Gruyere cheese. This combination will create a wonderfully gooey, melted cheese topping that adds depth to the casserole, contrasting beautifully with the creamy filling beneath.

Step 8: Bake Until Bubbly
Place the baking dish in the preheated oven and bake for 15-20 minutes. Keep an eye on it, and look for a bubbly texture and golden, slightly crispy cheese topping. You’ll know your Cheesy Brussels Sprouts Casserole is ready when the cheese is melted and the edges are bubbling—couldn’t be more inviting!
