1-First Step: Mise en place and mixing Gather your ingredients and pre-measure to streamline the process. In a large bowl combine the 1 pound lean ground beef, 1/4 cup panko breadcrumbs, 1 large egg (beaten), 2 teaspoons ketchup, 1 teaspoon Dijon mustard, 1/2 teaspoon dried oregano, and 1 teaspoon kosher salt. Mix gently with your hands or a fork until just combined. Overmixing will make the patties dense, so stop when everything is evenly distributed.

2-Second Step: Form and chill the patties Divide the meat mixture into 4 equal portions and shape each into oval patties about 3/4 inch thick. Place the patties on a plate and chill in the refrigerator for 20 to 30 minutes. Chilling helps them hold their shape during searing and prevents them from falling apart.

3-Third Step: Sear the patties Heat a large skillet over medium heat and add 1 tablespoon extra-virgin olive oil. When the oil shimmers, add the patties without crowding the pan. Sear for about 3 to 4 minutes per side, until a brown crust forms. The goal is a nice sear, not to fully cook through. Transfer seared patties to a plate and tent with foil while you make the gravy.

4-Fourth Step: Make the mushroom gravy In the same skillet, lower the heat to medium-low and add 2 tablespoons unsalted butter. When melted, add 6 ounces sliced cremini mushrooms and sauté for 3 to 4 minutes until they release moisture and begin to brown. Stir in 2 tablespoons flour and cook for 1 minute to remove raw flour taste. Gradually whisk in 1 1/2 cups beef stock to avoid lumps. Add 1 tablespoon ketchup, 1 teaspoon Worcestershire sauce, and 1/2 teaspoon onion powder. Simmer until the sauce thickens, about 3 to 5 minutes. Taste and season with salt and pepper as needed.

5-Fifth Step: Simmer patties in gravy Return the patties to the skillet, spoon some gravy over them, cover, and simmer on low for 8 to 10 minutes. This finishes cooking the patties gently and lets flavors meld. For beef, the internal temperature should reach 160°F. For ground turkey or chicken, cook to 165°F.

6-Final Step: Serving and finishing touches Serve Salisbury Steak over a bed of mashed potatoes with extra mushroom gravy spooned on top. Garnish with a sprinkle of chopped fresh parsley if desired. Let the skillet rest for a minute before plating to keep everything tidy.
