About This Recipe

Keto Hamburger Steak with Onion Gravy is a low-carb take on a classic American diner favorite. This recipe focuses on simple ingredients and bold, savory flavor—juicy beef patties paired with soft caramelized onions and a rich gravy made without flour or starch.

Hamburger steak is traditionally made from seasoned ground beef shaped into thick patties and pan-seared until deeply browned. That browning builds the base flavor for the gravy, creating a savory foundation that carries through the entire dish. The onions are cooked slowly until soft and lightly caramelized, adding natural sweetness that balances the richness of the beef.

Instead of flour-based gravy, this keto version relies on beef broth, butter, and gentle simmering to create a thick, glossy sauce. A small amount of xanthan gum is used to thicken the gravy while keeping the recipe fully low carb. The result is a smooth onion gravy that coats the hamburger steaks without becoming gummy or heavy.

This recipe works well for weeknight dinners, meal prep, and leftovers. The hamburger steaks stay juicy, the gravy reheats cleanly, and the flavors deepen as it rests. Serve it with mashed cauliflower, roasted green beans, or enjoy it on its own for a satisfying keto comfort food meal.
