Step-by-Step Instructions

Step 1: Cook the Pasta & Broccoli

Bring a large pot of salted water to a boil.
Cook fettuccine pasta until al dente, according to package instructions.
During the last 2 minutes of cooking, add broccoli florets to the boiling pasta.
Drain and set aside.

Step 2: Prepare the Chicken

If using uncooked chicken, heat olive oil in a skillet over medium heat.
Season the chicken with salt, pepper, and garlic powder, then cook for 5-6 minutes per side until golden and fully cooked.
Shred or cube the chicken and set aside.

Step 3: Make the Alfredo Sauce

In the same skillet, melt butter over medium heat.
Add garlic and sauté for 30 seconds until fragrant.
Pour in heavy cream and chicken broth, stirring well.
Bring to a gentle simmer, then add parmesan cheese, Italian seasoning, and nutmeg.
Stir until the sauce thickens (about 3-4 minutes).

Step 4: Assemble the Casserole

In a large bowl, combine the cooked pasta, chicken, and broccoli.
Pour the Alfredo sauce over the mixture and toss to coat evenly.
Transfer to a greased 9×13-inch baking dish.
Sprinkle mozzarella, parmesan, and breadcrumbs evenly over the top.

Step 5: Bake & Serve

Preheat the oven to 375°F (190°C).
Bake uncovered for 20-25 minutes, or until the cheese is melted and golden brown.
Let the casserole cool for 5 minutes before serving.

Common Mistakes to Avoid

Overcooking the Pasta – Cook until al dente, as it will continue cooking in the oven.
Using Too Much Sauce – The sauce should coat the pasta but not make it too runny.
Skipping the Cheese Topping – Adds a delicious golden, crispy texture to the casserole.

Variations & Substitutions

Use Different Pasta – Swap fettuccine for penne, rigatoni, or rotini.
Make it Lighter – Use half-and-half instead of heavy cream.
Add More Veggies – Mushrooms, spinach, or bell peppers work great!
Spicy Version – Add red pepper flakes for a kick.

Serving and Presentation Tips

Garnish with fresh parsley or basil for extra flavor.
Serve with garlic bread or a simple salad.
Drizzle with extra Alfredo sauce before serving for extra creaminess.

Refrigeration: Store in an airtight container for up to 3 days.
Freezing: Freeze in a freezer-safe dish for up to 2 months.
Reheating: Warm in the oven at 350°F (175°C) for 10-15 minutes, or microwave in 30-second intervals.
