Chicken Tetrazzini

I grew up on Chicken Tetrazzini but hadn't made it in ages!  I came across the recipe on Six Sisters Stuff and adapted it a bit to fit our taste!  This is such a great meal!

16oz linguine noodles
6 tbsp butter
6 tbsp flour
1/2 tsp salt
1/2 tsp pepper
3 1/2 cups chicken broth
1/2 cup cream
1/2 cup milk
3 chicken breast (cooked and shredded)
1 cup sliced mushrooms
1/4 cup diced pimentos
1 tbsp parsley
1/2 cup grated parmesan cheese
1/2 cup mozzarella cheese

Heat oven to 350. Boil the noodles according to directions.  Melt butter in a pan and whisk in flour over medium low heat.  Season with salt and pepper and let cook for 2 minutes.  Whisk in the chicken broth and bring to a simmer, when it begins to thicken up stir in cream and milk then remove from heat.  Combine the noodles, chicken, mushrooms, pimento, parsley and sauce.  Pour into a greased 9x13 baking dish and top with parmesan and mozzarella. Bake for 30 minutes. Remove from oven and serve.
