1 lb ground beef
1 medium onion, minced
8 ounces egg noodles
1 tablespoon butter
1 cup sour cream
1 (10 2/3 ounce) cans cream of mushroom soup

1/2 cup grated cheddar cheese ( or more if you'd like it cheesier)
crushed potato chips

Brown beef and onion together.
Cook noodles, drain and stir butter into hot noodles.
Mix together sour cream, soup and seasonings.
Alternate layers of noodles, beef mixture, cheese, and soup mixture(spread soup mixture as best you can, okay if it isn't evenly), in a greased 2 or 2 1/2 quart casserole.
Top with potato chips.
Bake at 350 degrees for 25-35 minutes.
