2 cups uncooked elbow macaroni
2 (5 oz) cans chunk chicken
2 cups shredded cheddar cheese
2 cups milk
2 cans condensed cream of chicken soup
1 (4 oz) can sliced mushrooms (I prefer using fresh mushrooms)
1/4 cup chopped onion
Preheat oven to 350 degrees.
In a large bowl, combine the macaroni, chicken, cheese, milk, soup, mushrooms, and onion. Mix together and transfer to a 9x13 baking dish.
Bake for about 45 minutes, or until bubbly and golden brown.
