The History Behind the Keto Beef Casserole Recipe

Casseroles have been a staple of American comfort cuisine since the 19th century. Traditionally made by combining meat, sauce, and starch in a single dish, they became synonymous with family-style meals. As dietary trends shifted, particularly with the rise of the keto diet, many casserole recipes were adapted to fit low-carb lifestyles. Ingredients like pasta and breadcrumbs were swapped for cauliflower rice and cheese, giving beef casseroles a keto-friendly makeover.
