How to Make Easy Brussels Sprouts Casserole with Smoked Turkey and Cheddar Recipe

Step 1: Preheat and Sauté Aromatics

Start by preheating your oven to 375°F (190°C). This sets the stage for baking the casserole until warm and golden. In a large skillet over medium heat, melt the butter. Once melted, add your minced shallots and garlic and sauté just for about 30 seconds until fragrant. This quick step gently releases their sweetness and ensures that your casserole base is bursting with flavor.

Step 2: Cook the Brussels Sprouts

Next, add your cleaned and halved Brussels sprouts to the skillet. Cook them for about 10 minutes, stirring occasionally so they soften evenly and soak up the buttery, garlicky mixture. The sprouts should be tender but still hold some bite—this texture is key to the dish’s appeal.

Step 3: Season and Stir in Cream

Sprinkle the cayenne pepper, mustard powder, salt, and freshly ground pepper over the sprouts. These spices add subtle complexity and warmth that complement the squashy creaminess. Then pour in the heavy cream and stir well to coat every sprout in smooth richness.

Step 4: Assemble and Top the Casserole

Transfer everything from the skillet into a baking dish. Evenly scatter the smoked turkey bits on top along with the shredded sharp white cheddar and Gruyere cheeses. This layering is what transforms the dish into a bubbly, golden casserole loaded with flavor bursts in every bite.

Step 5: Bake to Perfection

Place the casserole in your preheated oven and bake for 15 to 20 minutes, or until the cheeses are fully melted and lightly golden on top. As it bakes, the cheese melds with the creamy sprouts and smoky turkey, creating an irresistible golden crust you won’t be able to resist digging into.

Garnishes

To add freshness and a little crunch, sprinkle chopped fresh parsley or chives over the hot casserole right before serving. A light squeeze of lemon juice also brightens the rich flavors brilliantly, making each bite pop with freshness.

Side Dishes

This casserole is a versatile side that pairs wonderfully with roast chicken or pork tenderloin. For a cozy meal, serve alongside creamy mashed potatoes or a crisp green salad dressed with vinaigrette to counterbalance the richness.

Creative Ways to Present

For a fun twist, portion out the casserole into individual ramekins. This makes for a beautiful presentation when hosting guests and ensures everyone gets their share of that cheesy, savory goodness. Plus, topping with crunchy buttered breadcrumbs adds a delightful texture contrast that’s sure to impress.

Make Ahead and Storage

Storing Leftovers

Once cooled, store any leftover casserole in an airtight container in the refrigerator. It’ll stay fresh and tasty for up to 3 days, making it perfect for quick lunches or dinner reboots during the week.

Freezing

This casserole freezes beautifully. Wrap it tightly in plastic wrap and then foil before placing it in the freezer. When ready to enjoy, thaw overnight in the fridge and reheat in the oven until warmed through to preserve the creamy texture and melty cheese topping.

Reheating

For the best texture and flavor, reheat the casserole in a preheated oven at 350°F (175°C) for 15 to 20 minutes. This will ensure the cheese topping regains its golden crust and the filling remains creamy and warm throughout.
