Creating Bobby Flay’s Salisbury Steak with Mushroom Gravy is easy if you follow these simple steps:

1. Prepare the Beef Patties: In a large bowl, combine ground beef, bread crumbs, egg, Worcestershire sauce, onion powder, garlic powder, salt, and pepper. Mix until well combined.
2. Shape Patties: Divide the beef mixture into four equal portions. Shape each portion into oval patties about ¾ inch thick.
3. Heat the Pan: Heat the olive oil in a large skillet over medium heat. Once hot, add the patties and cook for about 3-4 minutes per side or until browned. Remove them from the skillet and set aside.
4. Sauté the Onions and Mushrooms: In the same skillet, add the butter. Once melted, add the chopped onions. Sauté until translucent. Then, add the sliced mushrooms and cook until they’re browned and tender.
5. Make the Gravy: Pour in the beef broth and soy sauce, stirring to combine with the onions and mushrooms. Return the patties to the skillet, cover, and let simmer for about 10 minutes to let flavors meld.
6. Thicken the Gravy (Optional): If you prefer a thicker gravy, mix cornstarch with a bit of water to create a slurry. Stir this mixture into the gravy and cook until it thickens.
7. Season and Garnish: Taste the gravy and add salt and pepper as necessary. Once done, sprinkle with fresh chopped parsley.
