Step 1

Preheat oven to 350°F.

Step 2

Cook the chicken if not already cooked and dice into bite sized pieces. Place in a large bowl.

Step 3

Bring a large pot of water to boil and cook pasta according to package directions. During the last 3 minutes, add the broccoli in with the pasta. Drain and rinse the pasta and broccoli with cold water to stop the cooking process. Pour into large bowl with the chicken.

Step 4

Make the Alfredo sauce: Place a large saucepan on the stove over medium heat and melt the butter. Whisk in the flour and continue to whisk the roux for 1-2 minutes

Step 5

Slowly whisk the milk in increments. Repeat until all milk has been added. Add in the Parmesan cheese, garlic, salt, pepper and Italian seasoning. Simmer for 2-3 minutes, stirring occasionally. Sauce will appear thin, but will thicken as it bakes.

Step 6

Pour the sauce over the pasta, broccoli and chicken and pour into your casserole dish/baking dish. Mix until combined and pasta is coated evenly.

Step 7

Top the pasta with mozzarella cheese and bake for 20-25 minutes or until the cheese is melted and barely begins to brown.

Step 8

Remove from oven and serve warm. Garnish with parsley or red pepper chili flakes, if desired!
