Method
Make the patties
- In a bowl, mix ground beef, breadcrumbs, egg, Worcestershire sauce, garlic powder, onion powder, salt, and pepper until evenly combined, then form into 4 oval patties about 3/4 inch thick.
- Heat a cast iron skillet over medium-high heat and sear patties for 3–4 minutes per side until browned; remove and set aside.
Cook the mushroom gravy
- Melt butter in the same pan and cook onion and mushrooms for 6–7 minutes until golden.
- Sprinkle flour over the vegetables and cook for 1 minute, then whisk in beef broth, Worcestershire sauce, and Dijon mustard until smooth.
- Simmer the gravy for 3–4 minutes until thickened, then return patties to the pan.
- Cover the skillet and cook for 10–12 minutes until the patties are cooked through, turning once if needed for even doneness.
Serve
- Garnish with fresh thyme and serve Salisbury steak over mashed potatoes with mushroom gravy poured on top.
Notes
For the best sear, let the patties sit 5 minutes at room temperature before cooking so the crust browns evenly. Store leftovers covered in the refrigerator up to 3 days; reheat gently in a skillet with a splash of beef broth until hot through. Freezing is not recommended because the gravy can change texture after thawing. For a lighter option, use lean ground beef (90% or 93%) to reduce fat while keeping the same seasoning and gravy.
