This bacon and cheese Brussels sprouts casserole delivers the perfect balance of smoky, crispy edges and creamy melted cheese—transforming a simple side into a showstopping main dish.

The secret lies in layering halved sprouts with crispy bacon and sharp cheddar, then baking until the top forms a golden, caramelized crust that holds every bite together. I developed this recipe after years of testing casserole techniques, and it never fails to impress—even picky eaters ask for seconds.

The beauty of this dish is its versatility—it works as a hearty side for Thanksgiving turkey or as a satisfying standalone meal when paired with crusty bread. The high-heat baking method ensures the bacon stays crispy while the cheese melts into a velvety blanket around the tender sprouts.

What sets this casserole apart is the crispy top layer—achieved by topping with extra cheese and baking until golden brown. The caramelized edges add a sweet contrast to the smoky bacon and sharp cheddar, creating a flavor profile that’s both comforting and exciting.

Ingredients for bacon and cheese brussel sprouts casserole

Twelve simple ingredients transform Brussels sprouts into a restaurant-worthy casserole with crispy bacon edges.

The bacon makes this dish—thick-cut stays crispy longer than regular slices. Oscar Mayer or Applegate are reliable brands, but any good-quality bacon works. Look for pieces with good marbling for extra flavor. The Brussels sprouts should be firm and vibrant green, not wilted or yellowing. Trim the ends before halving to ensure even cooking. For the cheese, sharp cheddar is non-negotiable—it melts beautifully and adds that tangy kick. If you can't find it, extra-sharp works in a pinch.

No thick-cut bacon? Regular bacon cut into 1-inch pieces works, but it'll crisp up faster. Swap cheddar for Gruyère or Monterey Jack if you're feeling fancy—both melt beautifully. The heavy cream can be replaced with half-and-half if you're watching calories, though the texture won't be quite as rich. For a dairy-free option, use full-fat coconut milk. The Panko breadcrumbs add texture, but if you're out, regular breadcrumbs toasted in the oven will do. Fresh thyme is ideal, but dried works at one-third the amount.

This casserole reheats beautifully—3-5 minutes at 350°F gets it crispy again. Store leftovers in an airtight container for 4-5 days in the fridge. For meal prep, assemble the dish ahead but bake it fresh for the best texture. Freezes well for up to 3 months—just thaw overnight in the fridge before reheating. The crispy top is best eaten the day it's made, so plan accordingly if you're making this ahead of time.

Step-by-step instructions for bacon and cheese Brussels sprouts casserole

Here's how to create a perfectly crispy, caramelized casserole with layers of smoky bacon and melted cheese.

In a large oven-safe skillet, cook the 12 oz thick-cut bacon over medium heat for 12-15 minutes, stirring occasionally, until golden brown and crispy. Use a slotted spoon to transfer the bacon to paper towels to drain, leaving the rendered fat in the skillet.

Reduce heat to medium-low and add the 2 lb trimmed, halved Brussels sprouts to the skillet. Toss them in the bacon fat for 5-6 minutes until they begin to soften and develop light brown spots. Sprinkle with 1 tsp dried thyme and 1.5 tsp salt during this step to infuse flavor. Remove the skillet from heat and set aside.

In a medium saucepan, melt the 4 tbsp unsalted butter over medium heat. Whisk in the 2 tbsp all-purpose flour and cook for 1-2 minutes until the mixture forms a smooth paste. Slowly pour in the 0.5 cup heavy cream while whisking continuously to prevent lumps.

Add the 2 cups shredded sharp cheddar cheese, 1 tbsp Dijon mustard, 0.5 tsp black pepper, and the 3 minced garlic cloves. Stir constantly over low heat until the cheese melts completely and the sauce thickens to a pourable consistency (about 3-4 minutes). Remove from heat and let cool slightly.

Return the skillet with Brussels sprouts and bacon to the stovetop. Pour the cheese sauce evenly over the top, spreading it to coat all the sprouts completely. The mixture will bubble slightly as it heats through.

In a small bowl, combine the 0.25 cup panko breadcrumbs and 0.25 cup freshly grated parmesan cheese. Sprinkle this mixture evenly over the top of the casserole, pressing down gently to create an even, crispy layer. The breadcrumbs will absorb any excess moisture and create that coveted crunch.

Transfer the skillet to a preheated 375°F oven and bake for 20-25 minutes until the top is deep golden brown and the edges are caramelized. The cheese should be fully melted and bubbling around the edges.

For the final 5 minutes, increase the oven temperature to 400°F to intensify the browning and crispiness. Watch closely during this time—you want that perfect balance of crispy top and creamy interior. Remove from oven when the top is deep golden brown and the edges are caramelized to a rich amber color.

Let the casserole rest for 5-10 minutes before serving. This resting period allows the cheese to set slightly and makes it easier to slice through the crispy top without losing the structure.

Serve immediately while the top is still crispy and the cheese is melted. The combination of smoky bacon, caramelized Brussels sprouts, and rich cheddar sauce creates a satisfying, comforting dish that's perfect for a weeknight dinner or holiday gathering.

Perfect pairings for this dish

Crispy Bread Pairings

This casserole pairs beautifully with crusty sourdough or baguette to soak up every last bit of the creamy cheese sauce. I love using a warm French baguette from my local bakery—its crispy crust contrasts perfectly with the soft, melty top.

For extra indulgence, try garlic bread with a spread of herb butter made from softened butter, minced garlic, and fresh parsley. 🥖

Protein Additions

Turn this into a full meal by adding crispy chicken tenders or sausage links on top before baking. I often use applewood-smoked sausage for extra depth, sliced into rounds and arranged in a circular pattern.

For a lighter option, try grilled shrimp or crispy prosciutto—both add a nice salty contrast to the rich cheese. 🍗

Fresh Greens Balance

A simple arugula salad with lemon vinaigrette cuts through the richness beautifully. Toss 4 cups baby arugula with 2 tbsp extra-virgin olive oil, 1 tbsp lemon juice, and a pinch of flaky sea salt.

For a heartier option, add shaved fennel or thinly sliced radishes for crunch. 🥗

Dipping Sauces

Serve with spicy honey mustard or creamy ranch for dipping. For the honey mustard, mix 2 tbsp Dijon mustard with 1 tbsp honey and a splash of apple cider vinegar.

The sweetness balances the smoky bacon perfectly. A blue cheese dressing also works wonderfully for those who love bold flavors. 🍯

Beverage Pairings

A crisp Sauvignon Blanc from New Zealand complements the dish beautifully—its citrus notes brighten the rich, cheesy flavors. For beer lovers, a Belgian witbier with its coriander and citrus undertones is a fantastic match.

If you prefer something lighter, an iced hibiscus tea with a squeeze of lime adds a refreshing contrast. 🍷
