Chicken Alfredo Casserole

I'm a big Chicken alfredo fan and I love the broccoli in this. I've cooked this this chicken up for other recipes too, has a great flavor! Try it! Love it!

Ingredients:
1lb spiral pasta (cooked according to package directions and drained)
3 boneless skinless chicken breast halves
¼ teaspoon dried rosemary
¼ teaspoon thyme
¼ teaspoon poultry seasoning
¼ teaspoon garlic powder
¼ teaspoon salt
3 cups shredded mozzarella cheese
8 ounces fresh sliced mushrooms (pre-cooked)
1 head of broccoli (cut into florets)
Alfredo Sauce-
½ cup sweet butter
2 garlic cloves (minced)
2 cups heavy cream
¼ teaspoon white pepper
½ cup grated parmesan cheese
¾ cup mozzarella cheese

Cooking Instructions:
Step 1: In a small bowl combine rosemary, thyme, poultry seasoning, garlic power and salt. Pound chicken breast halves to an even thickness. Season with the seasoning mixture on both sides of the chicken breasts. Place chicken onto a greased outdoor grill or indoor grill man. Grill until chicken is fully cooked. Allow chicken to cool and then slice into strips. Set aside.
Step 2: To make alfredo sauce: (the noodles can be cooked at this point) Melt butter in a medium saucepan over medium-low heat. Add the garlic, cream, white pepper and bring the mixture to a simmer. Stir often. Add parmesan cheese and simmer the sauce for 8-10 minutes or until the sauce has thickened and become smooth. Add the mozzarella cheese and cook until smooth.
Step 3: In a large bowl combine chicken, cooked pasta, broccoli, mushrooms, 1 cup of mozzarella cheese. Stir in alfredo sauce. Pour the mixture into a large casserole dish. Top with remaining mozzarella cheese. Bake in the oven at 350 degrees for 25-30 minutes.
