Shape the beef mixture into 4 oval patties.
In a shallow bowl, place the flour. Dredge the patties in the flour, shaking off the excess.
In a large skillet, heat the oil over medium heat. Add the patties and cook for 5 minutes, flipping once, until both sides are lightly browned.
Transfer the patties to the slow cooker.
In a small bowl, whisk together the beef broth, ketchup, and any remaining flour. Pour the mixture over the patties.
Cover and cook on low heat for 4-6 hours.
