Follow these simple steps to create your own Homemade Salisbury Steak:

1. Mix the Beef Patties: In a large bowl, combine the ground beef, breadcrumbs, chopped onion, egg, Worcestershire sauce, garlic powder, salt, and black pepper. Mix until well combined.
2. Form Patties: Shape the mixture into four equal patties, about 1/2 inch thick.
3. Cook the Patties: Heat olive oil in a large skillet over medium heat. Add the patties and cook for about 4-5 minutes on each side, or until browned and cooked through. Remove from the skillet and set aside.
4. Prepare the Gravy: In the same skillet, add sliced mushrooms and sauté until softened, about 4 minutes.
5. Thicken the Gravy: Sprinkle flour over the mushrooms and stir for 1 minute. Gradually add beef broth, stirring constantly to prevent lumps. Bring to a simmer.
6. Season the Gravy: Stir in soy sauce and dried thyme. Allow the gravy to thicken for about 3-4 minutes.
7. Combine Patties and Gravy: Return the cooked patties to the skillet, spooning gravy over the top. Simmer for an additional 5 minutes to heat through and blend flavors.
8. Serve: Remove from heat and serve warm.
