Three-Cheese Chicken Tetrazzini

Heat oven to 350 degrees F. Coat a 13 x 9 x 2-inch baking dish or casserole with nonstick cooking spray.

Cook spaghetti following package directions. Drain and rinse with cold water. Set aside.

In a large skillet, melt butter over medium-high heat. Add mushrooms, onion and garlic. Saute for 5 minutes. Add red pepper and sprinkle with flour. Cook, stirring, for 1 minute. Slowly stir in broth, heavy cream and milk. Simmer for 1 minute, until thickened.

Turn off heat; add cheeses. Stir until melted. Add salt, thyme, black pepper and chicken. Toss with cooked spaghetti and pour mixture into prepared dish.

Bake at 350 degrees F for 25 to 30 minutes until bubbling. Remove from oven and let stand for 10 minutes before serving.
