Ingredients in Sausage and Brussels Sprouts Casserole
Here’s where the magic begins—these ingredients might seem simple, but together, they create something truly special:
Sausage
The hero of this dish. Whether you’re using spicy or mild sausage, this adds so much flavor and richness to the casserole. The sausage becomes golden and crispy in all the right places, with a juicy, savory bite in every forkful.
Brussels Sprouts
These little guys are like the unsung heroes of the vegetable world. Roasting them brings out their natural sweetness, and when combined with sausage, they soak up all that delicious flavor, making every bite pure joy.
Creamy Sauce
A perfect, velvety sauce that ties everything together. Think of it as the glue that holds all these hearty ingredients in place. It’s rich, comforting, and makes every bite melt in your mouth.
Cheese
A sprinkle of cheese on top? Yes, please! It melts beautifully and adds that cheesy, gooey goodness that makes everything just a little more indulgent.

Instructions
Alright, let’s get cooking! Don’t worry, this one’s easy. Let’s dive in:
Preheat Your Oven
Start by preheating your oven to 375°F (190°C). It’s always good to get that oven nice and hot before you pop the casserole in—this ensures everything cooks evenly and gets that golden, crispy top.
Cook the Sausage
In a large skillet, brown your sausage over medium heat. Once it’s nice and crispy on the outside, break it up into bite-sized chunks. This is where all that savory flavor begins to develop, and your kitchen will smell amazing!
Prepare the Brussels Sprouts
While your sausage is cooking, slice the Brussels sprouts in half. Toss them with a little olive oil, salt, and pepper, then sauté them in the same skillet to give them a bit of color and tenderness before adding them to the casserole.
Assemble the Casserole
In a greased baking dish, layer the cooked sausage and Brussels sprouts. Pour over the creamy sauce and give it a quick mix so everything’s evenly coated. Sprinkle the cheese over the top—you want that golden crust, don’t you?
Bake to Perfection
Place the casserole in the preheated oven and bake for about 25-30 minutes, or until it’s bubbly and golden. The cheese should be melted, and everything should look like a glorious, comforting masterpiece.
Let it Cool
Once it’s out of the oven, let it cool for a few minutes before serving. This helps the flavors meld together and gives you a chance to catch your breath (and maybe grab a glass of wine!).
Serve and Enjoy
Dish it out while it’s still warm, and get ready to enjoy a meal that’s guaranteed to satisfy. Whether you serve it with a side salad or simply enjoy it on its own, this dish is sure to impress.
How to Serve Sausage and Brussels Sprouts Casserole
This casserole is perfect on its own or served with a few tasty sides to round out the meal:
Fresh Salads
Pair it with a light green salad to balance the richness of the casserole. A tangy vinaigrette will do wonders to cut through the creamy goodness.
Crusty Bread
Nothing beats a warm, crusty loaf of bread on the side to scoop up all the creamy sauce. Whether you choose garlic bread or just a plain baguette, it’s a must-have!
Creamy Accompaniments
For a little extra indulgence, serve it with a dollop of sour cream or a spoonful of Greek yogurt. The creaminess will complement the dish perfectly.
Roasted Vegetables
Add some roasted carrots, sweet potatoes, or even a side of green beans for a boost of color and nutrients to balance out the meal.
As a Standalone
Sometimes, this dish is hearty enough to enjoy on its own. Just garnish with some fresh herbs like parsley or thyme for a burst of freshness.

Add pasta and reserved cooking liquid. Stir until combined.
