Skillet Salisbury Steak

1 pound ground beef

1/2 C. bread crumbs

2 T. ketchup

1 T. Worcestershire sauce

1 tsp. mustard powder

1/2 tsp. garlic powder

1/2 tsp. kosher salt

1/2 tsp. ground black pepper

1 egg

2 T. butter

 

8 ounce mushrooms, sliced

1 small sweet onion, sliced

2 C. beef broth

1 T. ketchup

1 T. Worcestershire sauce

1 T. cornstarch

1 T. water

 

In a medium sized mixing bowl add the ground beef, bread crumbs, ketchup, Worcestershire sauce, mustard powder, salt, pepper, and egg. Mix with your hands until just combined and shape into 4 oval patties.  Heat the butter in a medium sized skillet over medium high heat. Add the patties and cook until the sides are slightly crisp and cooked throughout. Remove and set aside on a plate.  Add the mushrooms and onion to the pan and cook until tender, 4-5 minutes. Remove to the plate with the patties.  To make the gravy: Add the beef broth, ketchup, and Worcestershire sauce to the skillet. In a small bowl add the cornstarch and water creating a slurry. Whisk it into the gravy and bring to a boil. Reduce the heat to medium low and add the mushrooms, onions, and patties back to the skillet. Allow to simmer until the gravy starts to thicken. Salt and pepper to taste. Serve over mashed potatoes and peas and garnish with fresh parsley if desired.
