1 (12 oz.) package of medium egg noodles (I used bow-tie pasta) cooked about 1/2 the recommended time on the package directions.
4 chopped cooked chicken breasts
2 Tbsp. of butter or olive oil
1 (8 0z.) package of sliced Bella mushrooms
1 cup diced onions (optional)
2 (10 3/4 oz.) cans cream of chicken soup
1 pint sour cream
1 cup (4 oz.) shredded Parmesan cheese
Saute mushrooms in the butter or olive oil. Mix all ingredients, except the cheese, together. Place mixture in a slightly greased 9x13 pan. Sprinkle cheese on top. Place plastic wrap and then foil on top. Seal tightly.
Thaw completely. Bake in a preheated oven of 350 degrees for 35-45 minutes or until bubbly.
