Chicken Sour Cream Enchilada Casserole

My mom always made this dish when I was growing up. It was always the dish we served when company came over... not only by mom's choice but by many requests from guests. It is still one of my favorites as well as my husband and children. We serve this with various side dishes, depending on our mood. Some favorites include refried beans, Spanish rice, Spanish slaw, green salad, marinated tomato slices or calebacitas. My mom always made this in the traditional "enchilada style" with each enchilada rolled separately but I find it quicker and easier to make this like a casserole. Either way, it is delicious!

Chicken Sour Cream Enchilada Casserole

1 lb. chicken breast (boneless/skinless) cooked and diced (I use a food processor)
1 can cream of chicken soup
1 can Progresso brand cream of mushroom soup (If you can't find Progresso, use any brand with 1/2 soup can of milk added)
1/4 c. sour cream
1 can diced green chilis, drained
2 c. grated cheddar or Monterey Jack cheese
1 onion, minced
18 corn tortillas

Heat oven to 350 degrees. In a blender, combine soups and sour cream plus 1/2 c. of the cheese. Pour soup mixture into a sauce pan and heat through. Ladle a small amount of the soup mixture into a 9 x 13 in. pan. Add a layer of 6 corn tortillas, spread out to cover the bottom of the pan. Next add a layer of 1/3 of the chicken. Then add a layer of 1/3 of the onions. Then add a layer of 1/3 of the cheese. Then add a layer of 1/3 of the soup mixture. Then sprinkle with 1/3 of the green chilis. Repeat layers twice. Bake at 350 degrees for 30 minutes or until hot and bubbly and the cheese is melted.
