Salisbury Steak Patties : In a large bowl, combine the ground beef, Italian breadcrumbs, egg, milk, Worcestershire sauce, ketchup, mustard, onion powder, garlic powder, and black pepper. Mix until thoroughly combined. Divide the meat mixture into 4 equal oblong shaped patties.
1 pound ground beef, 1/2 cup Italian breadcrumbs, 1 large egg, 1 tablespoon whole milk, 1 tablespoon Worcestershire sauce, 1 tablespoon ketchup, 1 teaspoon onion powder, 1 teaspoon garlic powder, 1 teaspoon black pepper
In a large skillet pan, over medium-high heat, cook the hamburger patties on each side until browned with a nice crust to them. Remove the patties from the skillet pan and transfer them to a plate. * No need to cook until a safe internal temperature, just get a nice sear on the outside of the patties on both sides. Mushroom Gravy : Into the same skillet pan, add the butter, sliced mushrooms, and onions. Cook until the onions and have softened and the mushrooms have turned brown.* Remember to scrape up the pan drippings - all the browned bits off of the bottom of the skillet (lots of flavor there!). 3 tablespoons butter, 8 ounces sliced mushrooms, 1 small onion
Add in the flour and cook, while stirring constantly, until the mushrooms & onions are coated in the flour paste and it turns a golden brown color. About 1-2 minutes.
3 tablespoons all-purpose flour
Slowly stir in the beef broth, ketchup, Worcestershire sauce, and mustard. Using a wooden spoon, scrape the brown bits off of the bottom of the skillet pan.
3 cups beef broth, 2 tablespoons ketchup, 2 teaspoons Worcestershire sauce, 1 teaspoon dijon mustard
Simmer Salisbury Steak & Gravy : Reduce the heat to low-medium. Add the steaks back into the skillet pan and cook for an additional 10 minutes or until the meat reaches an internal temperature of 165℉ and the gravy has thickened.
Serve a patty over top some mashed potatoes and add a spoonful of the rich gravy mixture over top the cooked patties.
