Method
Step-by-Step
- Combine the ground beef, egg, breadcrumbs, minced onion, ketchup, Worcestershire sauce, mustard, garlic powder, salt, and pepper in a large bowl. Mix only until the ingredients are incorporated, then divide the mixture into four equal portions and shape each into an oval patty about 1/2 to 3/4 inch thick.
- Heat a large skillet over medium-high heat and add a small amount of oil if needed. Brown the patties for about 3–4 minutes per side, then transfer them to a plate; they do not need to be fully cooked yet.
- Reduce the skillet heat to medium and add the butter or oil. Sauté the sliced onion and mushrooms for approximately 5–7 minutes, until softened and lightly browned.
- Sprinkle the flour over the vegetables and stir for about 1 minute. Gradually whisk in the beef broth, then add the ketchup, Worcestershire sauce, and Dijon mustard.
- Stir the gravy for 2–3 minutes, until it begins to thicken. Return the patties and any accumulated juices to the skillet, cover, and simmer gently for 10–15 minutes, turning the patties once.
- Check that the ground beef reaches an internal temperature of 160°F (71°C). Taste the gravy, adjust with salt and pepper, and serve the patties generously covered with gravy.
Notes
Avoid overmixing the beef, because compacting the mixture can make the patties dense. For deeper flavor, use a small splash of red wine with the broth or add 1 teaspoon of beef bouillon or concentrated beef base, reducing added salt if using bouillon. Refrigerate leftovers promptly and reheat gently with a little extra broth if needed.
