1-Step 1: Prepare the Meat Mixture Start by gathering all your ingredients and bringing them to your workspace. In a large mixing bowl, combine 1 pound lean ground beef with 1/4 cup panko breadcrumbs, 1 large beaten egg, 2 teaspoons ketchup, 1 teaspoon Dijon mustard, 1/2 teaspoon dried oregano, and 1 teaspoon kosher salt. Using your hands, gently mix everything together until just combined. Be careful not to overmix, as this can make the patties tough and dense. The goal is to distribute the seasonings evenly while keeping the texture light.

2-Step 2: Shape the Patties Divide the meat mixture into 4 equal portions. Shape each portion into an oval patty about 3/4 inch thick. Make them slightly larger than you want the finished patties to be, as they will shrink during cooking. Press a small indentation in the center of each patty with your thumb. This technique prevents the patties from puffing up in the middle as they cook, ensuring even browning and a more attractive presentation.

3-Step 3: Brown the Patties Heat 1 tablespoon extra-virgin olive oil in a large skillet over medium-high heat. When the oil shimmers, carefully place the patties in the pan, leaving space between each one. Cook for 3-4 minutes per side until a deep golden-brown crust forms. The patties don’t need to cook through at this stage. They will finish cooking in the gravy. Transfer the browned patties to a plate and set aside.

4-Step 4: Start the Gravy Base In the same skillet, reduce the heat to medium and add 2 tablespoons unsalted butter. Let it melt and combine with the flavorful drippings left from browning the meat. Add 6 ounces sliced cremini mushrooms and cook for 4-5 minutes, stirring occasionally, until the mushrooms are softened and golden around the edges. The mushrooms release moisture as they cook, which adds body to the gravy.

5-Step 5: Create the Roux Sprinkle 2 tablespoons flour over the mushrooms and butter. Stir constantly for 1-2 minutes to cook the flour and remove any raw taste. The mixture should look paste-like and smell nutty. This roux is the foundation of your gravy, providing both thickening power and flavor depth.

6-Step 6: Add Liquid and Seasonings Slowly pour in 1 1/2 cups beef stock while whisking continuously to prevent lumps from forming. Add 1 tablespoon ketchup, 1 teaspoon Worcestershire sauce, and 1/2 teaspoon onion powder. Stir to combine all ingredients thoroughly. Bring the mixture to a gentle simmer, allowing it to thicken for 2-3 minutes.

7-Step 7: Return Patties to the Skillet Nestle the browned patties back into the gravy, spooning some sauce over the top. Reduce the heat to low and cover the skillet with a lid. Simmer for 10-15 minutes until the patties are cooked through and reach an internal temperature of 160°F. The low, slow cooking allows the flavors to meld and keeps the meat tender.

8-Step 8: Final Seasoning and Serve Remove the skillet from heat and taste the gravy. Add salt and pepper as needed to balance the flavors. The gravy should be rich, savory, and smooth. Serve the Salisbury steak hot over a bed of creamy mashed potatoes, spooning extra gravy over everything. For a complete meal, consider adding a side of hearty comfort food that pairs wonderfully with this dish.
