Jalapeño Chili Cornbread Casserole with Ground Beef

A hearty one-pan casserole that combines seasoned ground beef chili with a golden cornbread topping. The savory beef layer features tender onions, kidney beans, corn, and diced tomatoes with a kick from jalapeños, while the cornbread brings sweetness and texture with buttermilk tang. Melted Mexican cheese bridges both layers, creating a comforting dish perfect for family dinners or potluck gatherings. The cast iron cooking method ensures even heat distribution and creates appealing presentation when served directly from the pan.
