My mom made this casserole in our house a lot when my brother and I were growing up. It's a family favorite that never disappoints. It was one of the first recipes I asked my mom for when I moved out of the house.
Lightly brown beef and onion together. Add soups, sour cream, salt, and pepper; mix well. Add in noodles and corn; combine. Pour into a greased casserole dish. Cover and cook at 350 degrees for about 30 minutes or until bubbly.
