My Chicken Spaghetti

Directions

1. 1
   Preheat oven to 350 degrees F (175 degrees C).
2. 2
   Bring a large pot of lightly salted water to a boil. Cook spaghetti in the boiling water, stirring occasionally until cooked through but firm to the bite, about 12 minutes; drain.
3. 3
   Melt margarine in a large saucepan over medium heat. Stir flour into the margarine until the flour is completely moistened. Gradually stream milk into the saucepan while whisking with the flour mixture until the milk is incorporated into a smooth mixture.
4. 4
   Stir processed cheese food into the milk mixture in small amounts, letting each addition melt smoothly into the liquid before adding the next; add chicken, chicken broth, mushrooms, salt, and cayenne pepper. Stir mixture, add cooked spaghetti, and toss to coat. Divide the chicken spaghetti between 2 baking dishes.
5. 5
   Bake in preheated oven until the sauce is thick and the edges begin to brown, about 30 minutes.
