Baked Chicken Tetrazzini
4 tablespoons butter or margarine, divided
1 cup sliced white mushrooms
4 cups cubed cooked chicken
1/2 cup thawed frozen peas
3 tablespoons dry sherry or chicken broth
1/2 pound spaghetti
3 tablespoons all-purpose flour
1 cup chicken broth
1/2 cup heavy cream
1/2 teaspoon salt
1/4 teaspoon nutmeg
1/2 cup grated Parmesan cheese
In a large skillet, melt 2 tablespoons of butter over medium-high heat. Add mushrooms; saute, stirring, until tender, about 7 minutes. Stir in chicken, peas, and sherry. Remove from heat; set aside.
Cook spaghetti according to package directions. Drain thoroughly in a colander; set aside.
Preheat oven to 375F.
In a small saucepan, melt remaining butter over medium-high heat. Add flour; cook, stirring, until smooth and golden, about 2 minutes. Add broth; cook, stirring, until sauce thickens, 4 to 5 minutes. Stir in cream, salt and nutmeg.
Transfer cooked spaghetti and chicken mixture to a 13- x 9-inch baking dish. Pour sauce over top and mix well. Sprinkle with Parmesan; bake until cheese is lightly golden, about 20 minutes
