This dish marries the earthy flavors of roasted Brussels sprouts with a creamy, cheesy sauce that’s rich and satisfying. Let’s dive into the steps to prepare this wholesome side dish your guests will love.
Gather your ingredients
Before you start cooking, take a moment to gather all your ingredients. You’ll need:
- 1 to 1 ¼ pounds fresh Brussels sprouts, trimmed and halved or quartered
- 1 tablespoon olive oil
- 1 teaspoon kosher salt, plus more to taste
- ½ teaspoon freshly ground black pepper, plus more to taste
- 2 tablespoons unsalted butter
- 2 tablespoons all-purpose flour
- 1 cup whole milk or half-and-half
- ½ cup shredded gruyere cheese, divided
- ¼ cup grated parmesan cheese, divided
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- Optional garnishes: cooked turkey bacon, sliced green onions, red pepper flakes, fresh herbs, or extra cheese
Now that all your ingredients are ready, let’s get cooking!
Roast the Brussels sprouts
Preheat your oven to 425°F (220°C). This high heat helps caramelize those Brussels sprouts beautifully. In a baking dish, toss the trimmed Brussels sprouts with olive oil, salt, and pepper until they’re evenly coated. Spread them out in a single layer and roast for about 20 minutes until they’re tender and have a lovely golden color. The aroma will be heavenly!
Make the creamy cheese sauce
While the Brussels sprouts are roasting, you can whip up the creamy cheese sauce. In a medium saucepan or skillet, melt the butter over medium heat. Add the flour and cook for about one minute, stirring continuously to create a roux. This step is essential as it thickens the sauce later on. Gradually whisk in the milk, stirring vigorously to prevent lumps. Once the mixture thickens, add half of the gruyere and parmesan cheeses, along with garlic and onion powders, salt, and pepper. Stir until the cheese is completely melted and incorporated.
Combine and assemble
Once the Brussels sprouts are perfectly roasted, pull them from the oven and lovingly drizzle the creamy sauce over them. This is where the magic happens! Mix everything gently to ensure that every sprout is coated in that delicious sauce. Top it off with the remaining cheeses for that irresistible cheesy goodness.
Bake to perfection
Return the dish to the oven and bake for another 10-15 minutes until the cheese is bubbling and golden brown. If you're feeling adventurous, broil for an additional 1-2 minutes for an extra crispy top. Just keep an eye on it; things can go from golden to burnt quickly!
And there you have it! You’ve prepared a scrumptious Brussels Sprouts Casserole that’s destined to be a hit. Enjoy this creamy, flavorful dish as a side at your next gathering, and watch your friends and family revel in its delightful taste. Want to learn more about variations or tips for make-ahead meals?
