A king ranch chicken casserole is just the kind of hot, bubbly comfort weve all come to expect from southern cooking. It hails from texas named after the biggest ranch in the state even though theres no actual link between the recipe and the ranch itself. Its unabashed comfort food cheesy, creamy, and usually reliant on a can of cream of mushroom soup. Our version skips the can but still brings you all the creaminess and flavor you could want, just in a more from scratch manner.
