Bacon and Cheese Brussels Sprouts Casserole Recipe: Crispy-Topped, Smoky-Bacon Crunch

This bacon and cheese Brussels sprouts casserole recipe transforms humble sprouts into a crispy-topped, smoky masterpiece that steals every holiday table. 🔥 The secret lies in layering crispy bacon with tender sprouts and a golden cheese crust that crackles with every bite—no one will guess it started with a vegetable most people avoid.

Smoked paprika adds depth while sharp cheddar delivers that classic comfort-food tang. It’s the kind of dish that turns Brussels sprouts from sidekick to star.

By the time it emerges from the oven, you’ll have a restaurant-quality casserole with layers of texture—crispy bacon, tender sprouts, and a blanket of melted cheese that holds its shape.

The aroma alone will have everyone gathering around the table, and the first bite proves this is comfort food at its finest.

Serve it as a main dish with crusty bread or as a showstopping side for roasted meats. The leftovers reheat beautifully, making it perfect for meal prep too. Here’s how to make it—foolproof and impossible to resist.

Ingredients for bacon and cheese brussel sprouts casserole

Six ingredients transform Brussels sprouts into a crispy, cheesy, bacon-packed showstopper.

The bacon is non-negotiable—thick-cut makes all the difference. Oscar Mayer or Applegate are reliable brands, but any high-quality bacon works. Look for pieces with good marbling for maximum flavor. The Brussels sprouts should be firm and vibrant green—avoid any with yellowing leaves. Trim the ends and halve them lengthwise for even roasting. For the cheese, sharp cheddar like Cabot or Tillamook delivers that tangy punch, but Pepper Jack works too if you want extra heat.

No thick-cut bacon? Regular bacon cut into 1/2-inch pieces will work, but it won’t crisp as well. Running short on cheddar? Gruyère or Gouda add a different depth, though they’ll melt slightly softer. The panko can be swapped for crushed cornflakes if you’re out, but it won’t be as crispy. For the smoked paprika, regular paprika plus a pinch of liquid smoke gets you close. The garlic and onion powders are interchangeable—just use whichever you’ve got. Heavy cream can be swapped for half-and-half if needed, though the texture will be slightly lighter.

Roast the sprouts immediately after trimming for best texture. Store any extra bacon in the freezer for up to 6 months—it’s perfect for quick toppings. The shredded cheese keeps well in an airtight container for 3 months, but once opened, use it within 2 weeks. Assembled casserole can be refrigerated for 2 days before baking. For make-ahead convenience, prep the layers in advance and refrigerate until ready to bake—just add 10 minutes to the baking time.

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

Here's how to build a rich, crispy-topped casserole with smoky bacon and melty cheese.

Preheat your oven to 425°F. In a large bowl, toss the 2 lb Brussels Sprouts with 2 tbsp Extra-Virgin Olive Oil, 1 tsp Garlic Powder, 1 tsp Onion Powder, 1 tsp Salt, and 0.25 tsp Black Pepper. Spread them evenly on two rimmed baking sheets.

Roast for 18-20 minutes, stirring once halfway through, until the edges are deep golden brown and the sprouts are tender when pierced with a fork. The high heat caramelizes the natural sugars, creating that perfect sweet-savory flavor. Remove from oven and set aside for now.

In a large skillet over medium heat, cook the 12 oz Thick-Cut Bacon in batches until deep golden and crispy, about 8-10 minutes per batch. Use a slotted spoon to transfer the bacon to paper towels to drain, leaving the rendered fat in the skillet.

While the bacon cooks, reduce heat to low and stir in 0.5 cup Heavy Cream and 1 tbsp Smoked Paprika. Let it simmer for 2 minutes until slightly thickened. Remove from heat and stir in 1.5 tsp Salt and the remaining 0.25 tsp Black Pepper. Set aside.

In a large oven-safe skillet or baking dish, spread half of the roasted Brussels Sprouts evenly across the bottom. Sprinkle 1 cup Sharp Cheddar Cheese over the sprouts, followed by half of the cooked bacon. Repeat with another layer of sprouts, remaining cheese, and the remaining bacon.

Pour the warm cream mixture evenly over the top, making sure it seeps down between the layers. This creates a creamy base that will bind everything together as it bakes. The layers should be compact but not packed down—press gently to settle them.

In a small bowl, mix together the 0.5 cup Panko Breadcrumbs, 2 tbsp Butter, and any remaining bacon fat from the skillet. Sprinkle this mixture evenly over the top of the casserole, pressing down gently to create a continuous layer. This topping is what gives your casserole that irresistible crispy texture.

Bake uncovered at 375°F for 20-25 minutes until the top is deep golden brown and the cheese is fully melted and bubbly. The edges should be slightly crispy, and the center should be hot throughout. If the top browns too quickly, tent loosely with foil for the last 5 minutes.

Remove the casserole from the oven and let it rest for 5-10 minutes before serving. This resting period allows the layers to set slightly, making it easier to slice cleanly. The crispy topping will firm up during this time, giving you that perfect crunch with every bite.

Serve warm with extra bacon crumbles on top if desired. The combination of crispy Brussels Sprouts, smoky bacon, and creamy cheddar creates a satisfying texture contrast. Each forkful delivers tender sprouts, rich cream sauce, and that addictive crispy top layer.

These fats also enhance flavor without adding excessive calories.

Fiber for Digestion

Brussels sprouts are a fiber superstar, with 2 pounds providing about 12 grams of fiber—nearly half your daily needs. This fiber supports gut health, aids digestion, and helps maintain steady blood sugar levels.

The caramelization process during roasting actually increases the sprouts' glycemic load, making them more digestible while preserving their nutrients. The crispy texture from the panko topping adds an extra satisfying crunch without compromising nutritional benefits.

Vitamin K Boost

Brussels sprouts are one of the best sources of vitamin K, with this recipe providing over 100% of your daily needs per serving. Vitamin K is crucial for blood clotting and bone health, working with calcium to strengthen your skeleton.

The sharp cheddar also contributes to this nutrient profile, making this dish a great way to support both muscle and bone health simultaneously.

Iron for Energy

The combination of bacon and Brussels sprouts provides a solid dose of iron, essential for transporting oxygen throughout your body. A single serving delivers about 3 mg of iron, which helps prevent fatigue and supports your immune system.

The smoked paprika in the recipe also contains trace amounts of iron, adding to the dish's nutritional value. This makes it particularly beneficial for those with active lifestyles or iron-deficiency concerns. 💡

Low-Carb Comfort

While this casserole is rich and indulgent, it's surprisingly lower in carbs than many comfort foods. The Brussels sprouts provide complex carbohydrates for energy without the blood sugar spikes of refined grains. The panko topping adds minimal carbs while delivering that satisfying crunch.

For a lighter version, you could reduce the panko to ¼ cup without sacrificing texture, making this dish a great option for those monitoring their carb intake.
