salisbury steak

Directions :

1. In a 12-inch skillet, melt the butter over medium heat. Add the sliced onion and cook until softened, about 3 to 4 minutes. Add the mushrooms and continue cooking until the liquid has been released and is almost evaporated. Transfer to a bowl and set aside.
2. Meanwhile, in a large bowl, combine the beef, ¼ cup beef broth, bread crumbs, egg, garlic powder, and black pepper. Shape into 6 patties, 4 inches in diameter.
3. Add the flour to a small bowl. Add about 2 tablespoons of beef broth and whisk until smooth. Add the remaining beef broth, ketchup, Worcestershire sauce, mustard powder, and water.
4. Place half of the beef patties in the same skillet over medium heat and brown for 2 minutes per side —they do not need to be cooked through. Transfer to a plate and brown the remaining patties.
5. Add all of the beef patties back to the skillet and top with the mushroom mixture. Whisk the sauce and pour over the patties.
6. Bring to a simmer over medium-low heat and cover. Simmer for 14 to 20 minutes or until the beef is cooked through.
7. Serve over mashed potatoes or egg noodles.
