Chicken cornbread casserole is creamy and savory with a cornbread topping that is slightly sweet and crumbly. Together with the cheesy sauce, the flavors are comforting and feel rich.
The end result is a cheesy blend of sweet, tender onions and browned bits of smoke Gouda and mild Cheddar. The secret to making this casserole shine? The onions, of course. But not just any onions.
