Step‑by‑Step Instructions for Brussels Sprouts Casserole

Step 1: Preheat Your Oven
Begin by preheating your oven to 375°F (190°C). This ensures a perfectly cooked Brussels Sprouts Casserole with a golden, bubbling top. While the oven heats, gather your baking dish and other ingredients to streamline your cooking process.

Step 2: Sauté Aromatics
In a large skillet, melt 2 tablespoons of butter over medium heat. Add the minced shallots and garlic, sautéing for about 30 seconds until they become fragrant and light golden. This aromatic base enhances the flavors of the Brussels sprouts, creating a delicious foundation.

Step 3: Cook the Brussels Sprouts
Next, add the cleaned and halved Brussels sprouts to the skillet. Cook them for approximately 10 minutes, stirring occasionally, until they are tender but still vibrant green. Season with salt, pepper, cayenne pepper, and mustard powder, allowing the spices to mingle with the sprouts for a robust flavor.

Step 4: Create the Creamy Sauce
Once the Brussels sprouts are tender, lower the heat and stir in 1 cup of heavy cream. Mix well until all ingredients are thoroughly combined and the cream begins to thicken slightly. This creamy element will coat the Brussels sprouts beautifully, making the casserole rich and comforting.

Step 5: Assemble the Casserole
Transfer the creamy Brussels sprouts mixture to a greased baking dish, spreading it evenly. Sprinkle the crumbled bacon over the top, followed by the shredded sharp white cheddar and Gruyere cheese. This ensures that every bite of the Brussels Sprouts Casserole is cheesy and indulgent.

Step 6: Bake to Perfection
Place the assembled casserole in the preheated oven and bake for 15 to 20 minutes. Keep an eye on it as it bakes; you’re looking for a melted, golden-brown cheese topping that is slightly bubbly around the edges. This will signify that your Brussels Sprouts Casserole is ready to be enjoyed.

Make Ahead Options

These Cheesy Brussels Sprouts Casserole are a lifesaver for busy weeknights! You can prepare the entire casserole up to 24 hours in advance by following all the steps up to the baking part. Once completed, simply cover it tightly with foil or plastic wrap and refrigerate. This not only saves time but also allows the flavors to meld deliciously. When you’re ready to serve, just remove the cover and bake in the preheated oven for about 20-25 minutes until the cheese is bubbling and golden. Rest assured, the casserole will be just as scrumptious as if made fresh, making it a perfect meal prep option!

Brussels Sprouts Casserole Recipe FAQs

How do I select the best Brussels sprouts?
Absolutely! When choosing Brussels sprouts, look for ones that are firm and compact with vibrant green leaves. Avoid any that have yellowed or have dark spots, as this can indicate overripeness. The stems should be cut cleanly; fresh sprouts should feel heavy for their size.

What is the best way to store leftover Brussels Sprouts Casserole?
After cooling completely, place your leftover Brussels Sprouts Casserole in an airtight container in the fridge, where it will stay fresh for up to 3 days. Always ensure it’s properly sealed to avoid moisture buildup.

Can I freeze Brussels Sprouts Casserole?
Yes! To freeze your casserole, wrap it tightly in plastic wrap and again in aluminum foil or use a freezer-safe dish. It can be stored in the freezer for up to 2 months. When you’re ready to enjoy it, thaw it overnight in the fridge before baking.

What should I do if my Brussels sprouts are mushy after cooking?
Very! If your Brussels sprouts turn mushy, it’s essential to monitor cooking time when sautéing. Aim for about 10 minutes of cooking until tender but still firm. If they do become mushy, consider blending them with the cream sauce to create a smooth texture that still delivers the delicious flavor.

Are there any dietary considerations for this recipe?
Of course! This casserole contains dairy and bacon. If you’re cooking for anyone with dietary restrictions, consider using turkey bacon or omitting it for a vegetarian option. For dairy-free versions, substitute heavy cream with coconut cream or a plant-based milk and choose a vegan cheese. Always check for allergies related to particular cheeses or ingredients as well.
