Introduction

The Savory Keto Kentucky Hot Brown Casserole is a mouthwatering twist on a Southern classic that has delighted food lovers for nearly a century.

This modern version transforms that beloved dish into a low-carb, keto-friendly casserole without losing any of its signature comfort or indulgence.
