Keto Kentucky Hot Brown Casserole

There is something incredibly comforting about pulling a bubbling, golden casserole out of the oven, especially when it smells like creamy sauce, melted cheese, and warm roasted turkey.

Trust me, you’re going to love this, it is cozy, satisfying, and honestly hard to stop eating once you start.

A comforting classic with a keto twist you will crave

Instead of layering everything on bread, we build it into a creamy, hearty bake that lets every bite soak up flavor. And now let’s dive a little deeper into where this comforting idea comes from.
