Easy Delicious Salisbury Steak

0 In a large bowl, combine the ground beef, breadcrumbs, egg, milk, ketchup, Dijon mustard, Worcestershire sauce, garlic powder, onion powder, salt, and pepper. Mix until just combined and form into 4–5 oval patties.
1 Heat a large skillet over medium heat. Cook the patties for 3–4 minutes per side until browned, depending on the size. Remove from the skillet and set aside.
2 In the same skillet, melt the butter with the olive oil. Add the sliced onions and cook for 10–12 minutes until soft and golden.
3 Sprinkle the flour over the onions and stir for 1 minute. Slowly pour in the beef broth while stirring until smooth. Stir in the Worcestershire sauce, ketchup, and soy sauce.
4 Return the patties to the skillet. Cover and simmer on low for 10–15 minutes, or until the patties are cooked through and the gravy has thickened. Serve warm with extra gravy spooned over the top. Enjoy!
