Cheesy Chicken Potato Casserole

The creamed soups are something that I plan to work on, trying to make and can some that will duplicate what I buy. For now though, as long as the prices hold at Save A Lot, the .69 cream soups are cheaper than what I can make and put up.

Cheesy Chicken Potato Casserole
4 boneless skinless chicken breasts
1 teaspoon seasoned salt
1 T olive oil
1 can cream of celery soup
2/3 cup milk
1/2 cup sour cream
pepper to taste
3 large potatoes, diced
1 1/2 cups cheddar cheese, grated
1 1/2 cups french fried onions.

Sprinkle chicken with the seasoned salt, and brown them lightly in a skillet with the oil. In a small bowl, stir together the grated cheese and onions; divide in half and set aside. In a large bowl, stir together the milk, sour cream, soup, pepper. Stir in the hash browns and cheese/onion mixture, then pour into a 13X9 dish that has been greased with butter. Arrange the chicken on top. Cover and bake for 40 minutes. Then uncover & sprinkle the remaining cheese/onion mixture on top; bake uncovered for 10 minutes.
