How to make Salisbury Steak Garlic Mash Potatoes Mushroom & Onion Gravy
Salisbury Steak Patties:
Step 1: Place the grated onion (with its juices), the bread crumbs, the egg, kosher salt, and black pepper in a large bowl. Mix well until blended. Then, add the lean ground beef and mix well using your hands until everything is fully combined.
Step 2: To make four patties, evenly divide the beef mixture. Shape each patty into a 3/4-inch thick oval.
Step 3: On high, heat a large skillet. Once searing hot, drizzle 1 tbsp olive to the skillet and swirl the pan to coat. Add the patties and cook for about 2 minutes per side or until brown. To a plate, transfer the seared patties and set them aside.
Mushroom Gravy:
Step 4: To the skillet, melt 2 tbsp butter. Then, add the sliced mushrooms and cook for about 2 minutes or until golden. Over the mushrooms, sprinkle the flour. Stir well to coat the mushrooms and continue to cook for another minute.
Step 5: To the skillet, pour in the broth while stirring constantly. Let it simmer for about 5 minutes or until the sauce has thickened.
Step 6: Return the partially cooked steak to the skillet and simmer for an additional 5 to 10 minutes until the gravy has thickened and the internal temperature of the steak reaches 160 degrees F.
Step 7: Over mashed potatoes, serve the steak, and drizzle with mushroom gravy. Enjoy!
