The result is a bubbling, golden casserole that looks as impressive as it tastes, making it ideal for both weeknight dinners and entertaining guests.

Essential Ingredients

For the Base:

• 1.5 lbs boneless chicken (breasts or thighs), cubed
• 12 oz pasta (penne, rigatoni, or shells work beautifully)
• 3 cups fresh broccoli florets
• 2 cups alfredo sauce (homemade or quality jarred)
• 1/2 cup heavy cream
• 1 cup chicken stock
• 2 cups shredded mozzarella cheese
• 3/4 cup grated Parmesan cheese

Seasonings:

• 2 tsp Italian herb blend
• 1 tsp garlic powder
• Salt and black pepper to taste
• 2 tbsp olive oil

Optional Flavor Boosters:

• 1/2 cup sun-dried tomatoes, chopped
• 8 oz sliced mushrooms
• 2 cups fresh spinach
• 1/4 cup fresh basil, chopped
• Red pepper flakes for heat

Step-by-Step Preparation

Getting Started

Preheat your oven to 375°F and lightly oil a 9×13-inch baking dish. This temperature provides the perfect balance for cooking chicken thoroughly while achieving that golden, bubbly cheese top.

Season the cubed chicken generously with Italian herbs, garlic powder, salt, and pepper. Let it rest while you prepare the other components – this brief marinating time enhances flavor penetration.

Pasta and Vegetable Prep

Cook your pasta until just shy of al dente – about 2 minutes less than package directions suggest. The pasta will finish cooking in the oven, so this prevents overcooking and mushy textures.

For the broccoli, give fresh florets a quick 2-minute blanch in boiling water, then immediately plunge into ice water. This preserves the vibrant green color and ensures the broccoli maintains some bite in the finished dish.

Creating the Sauce Base

In a large bowl, whisk together the alfredo sauce, heavy cream, and chicken stock until smooth. This mixture should coat the back of a spoon nicely – not too thick, not too thin. The added liquid is crucial as it gets absorbed during baking, keeping everything moist and creamy.

Assembly Magic

Toss the slightly undercooked pasta, seasoned chicken, and blanched broccoli with the sauce mixture until everything is well-coated. The key is ensuring every piece gets adequate sauce coverage for consistent flavor throughout.

Spread this mixture evenly in your prepared baking dish. Cover tightly with foil – this traps steam and ensures the chicken cooks through completely while preventing the top from browning too quickly.

The Baking Process

Bake covered for 30 minutes, then remove the foil and sprinkle with both cheeses. Continue baking uncovered for 15-20 minutes until the chicken reaches 165°F internally and the cheese is golden and bubbly.

Let the casserole rest for 10 minutes before serving – this cooling period allows the sauce to set slightly, making it easier to serve neat portions.

Expert Tips for Success

Temperature Control: Use an instant-read thermometer to check chicken doneness. The internal temperature should reach 165°F in the thickest pieces.

Pasta Choice: Shapes with ridges or hollow centers (like rigatoni or shells) hold the sauce better than smooth varieties, creating more flavorful bites.

Cheese Strategy: Mix aged cheeses like Romano or Asiago with the mozzarella for more complex flavors. Save some Parmesan for sprinkling on individual servings.

Make-Ahead Friendly: Assemble the entire casserole up to 24 hours ahead. Cover and refrigerate, then add 10-15 minutes to the covered baking time when cooking from cold.

Serving and Pairing Ideas

This rich, satisfying casserole pairs beautifully with lighter sides that provide textural contrast. A crisp Caesar salad, roasted Brussels sprouts, or simple steamed green beans balance the richness perfectly.

Garlic breadsticks are classic for a reason – they’re perfect for sopping up any extra sauce. For wine lovers, a crisp Pinot Grigio or light Chardonnay complements the creamy flavors without overwhelming them.

Nutritional Highlights

Each generous serving provides approximately 520 calories with 32 grams of protein, making this a substantial meal that satisfies hunger while delivering quality nutrients. The addition of broccoli boosts fiber content and adds vitamins C and K.

To lighten the dish, substitute part-skim cheeses, use Greek yogurt in place of some heavy cream, or bulk up servings with extra vegetables while reducing pasta portions.

Creative Variations

Mediterranean Twist: Add artichoke hearts, sun-dried tomatoes, and fresh basil for bright, sophisticated flavors.

Protein Swaps: Leftover rotisserie chicken, cooked shrimp, or Italian sausage all work beautifully in place of fresh chicken.

Vegetable Medley: Swap broccoli for asparagus, zucchini, or bell peppers based on seasonal availability and personal preferences.

Spicy Version: Add red pepper flakes, diced jalapeños, or a splash of hot sauce for those who enjoy heat with their comfort food.
