Optional Personal Story
I created this casserole on a hectic school night when I needed something fast but still wholesome. Using rotisserie chicken and cottage cheese turned it into a creamy, comforting dish that tasted like it took far more effort than it did. It quickly became a family favorite — especially on nights when time is tight but we want something warm and homemade.
