Cheesy Chicken & Brussels Sprouts Pasta Bake Ingredients
For the Pasta Bake
• Brussels Sprouts – Cruciferous veggie that adds nutritional value and a unique texture; use fresh or frozen, cut in halves for quicker cooking.
• Cheese Tortellini – Provides a hearty base with tender pasta, packed with cheese; both refrigerated and frozen varieties can be used interchangeably.
• Boneless Skinless Chicken Breast – Primary protein source that adds heartiness to the dish; can substitute with cooked rotisserie chicken for ease.
• Bacon – Adds a smoky flavor and crispy texture; turkey bacon can be used for a leaner option.
• Garlic – Enhances flavor with its aromatic qualities; minced garlic can be substituted with garlic powder.
• Low Sodium Chicken Broth – Provides moisture and flavor; vegetable broth can be used for a lighter taste.
• Fat-Free Half and Half – Offers creaminess without the fat; regular half and half can be used for a richer dish.
• White Cooking Wine – Enhances flavors and depth of the sauce; in a pinch, use an equal amount of chicken broth.
• Reduced Fat Margarine – Used for sautéing and as a base for the sauce; can use olive oil as a healthier fat alternative.
• Flour – Thickens the sauce for a creamy consistency; no substitutions necessary, but cornstarch can be used as a gluten-free option.
• Reduced Fat Shredded Mozzarella – Melts and binds the dish together, contributing to cheesiness; regular mozzarella can also be used.
• Parmesan Cheese – Adds a sharp, salty flavor topping; nutritional yeast offers a dairy-free alternative with similar flavor profiles.
• Salt/Pepper – Essential for seasoning; adjust to taste.
Optional Topping

Step‑by‑Step Instructions for Cheesy Chicken & Brussels Sprouts Pasta Bake
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This ensures the Cheesy Chicken & Brussels Sprouts Pasta Bake cooks evenly and develops that golden, bubbly top we all crave. While the oven warms up, gather your ingredients to streamline the cooking process.
Step 2: Cook the Bacon
In a large pot, place the bacon over medium-high heat. Sauté until it turns crispy, about 5-7 minutes. Once done, transfer the bacon onto a plate lined with paper towels to absorb excess grease, and crumble it once cooled. This will add a smoky depth to our pasta bake.
Step 3: Sauté the Aromatics
Using the same pot, melt the reduced-fat margarine over medium heat. Add the minced garlic, allowing it to cook for about 1-2 minutes until fragrant. Then pour in the low-sodium chicken broth and white cooking wine, letting the mixture simmer gently for about 5 minutes. This creates a flavorful base for your casserole.
Step 4: Make the Creamy Sauce
Stir in the fat-free half and half, followed by the reduced-fat shredded mozzarella cheese and flour. Continuously stir the mixture until it begins to simmer and thicken into a creamy sauce, about 3-4 minutes. This luscious sauce is vital for bringing the flavors of your Cheesy Chicken & Brussels Sprouts Pasta Bake together.
Step 5: Add the Main Ingredients
Once your sauce has thickened, add in the Brussels sprouts, cheese tortellini, cooked chicken, and half of the crumbled bacon. Season generously with salt and pepper to taste. Stir everything until well combined, ensuring that every piece of tortellini is covered with that delightful sauce.
Step 6: Transfer and Top
Carefully pour the cheesy chicken and Brussels sprouts mixture into a greased 13×9-inch baking dish. Spread it evenly and take a moment to enjoy the vibrant colors. Sprinkle the remaining Parmesan cheese and crumbled bacon over the top. This will create a beautifully savory crust as it bakes.
Step 7: Bake to Perfectness
Place the baking dish in the preheated oven and bake for 35 to 40 minutes, or until the top is bubbly and golden brown. Keep an eye on it as it cooks; you want that inviting aroma to fill your home. For an extra crispy topping, consider broiling for an additional 5 minutes.
Step 8: Let It Rest and Serve
Once baked, carefully remove the Cheesy Chicken & Brussels Sprouts Pasta Bake from the oven and let it rest for about 5 minutes. This allows the dish to set, making it easier to serve. Cut into squares and savor the comforting blend of textures and flavors with your loved ones!
