Ingredients:
- 680g (1.5 lbs) Ground Beef (80/20 blend)
- 80g (1 cup) Panko Breadcrumbs (or finely crushed crackers)
- 1 large Egg, lightly beaten
- 1/4 cup finely minced Yellow Onion (for patties)
- 1 Tbsp Worcestershire Sauce (for patties)
- 1 tsp Dijon Mustard (or mustard powder)
- 1 tsp Garlic Powder
- 1 tsp Kosher Salt
- 1/2 tsp Black Pepper
- 2 Tbsp All-Purpose Flour (for dusting patties)
- 2 Tbsp Canola Oil (or other neutral high-heat oil)
- 225g (8 oz) Cremini Mushrooms, sliced ('Baby Bellas')
- 2 Tbsp Unsalted Butter
- 1 large Shallot or 1/4 cup Yellow Onion, finely minced (for gravy)
- 2 Tbsp All-Purpose Flour (for roux)
- 480 ml (2 cups) High-Quality Beef Stock (low sodium)
- 1 Tbsp Ketchup
- 1 Tbsp Worcestershire Sauce (for gravy)
- 1/2 tsp Dried Thyme
- Salt and freshly ground Black Pepper to taste (for gravy)
- 1 Tbsp fresh Parsley, chopped (optional garnish)
Instructions:
- Combine Ingredients: In a large mixing bowl, gently combine the ground beef, panko, beaten egg, minced onion, 1 Tbsp Worcestershire, Dijon mustard, garlic powder, salt, and pepper. Use your hands, but mix lightly to avoid tough patties.
- Form and Chill: Divide the mixture into four equal portions, forming each into an oval or rectangular patty, roughly 3/4 inch thick. Place the patties on a plate and chill in the refrigerator for a minimum of 30 minutes. This step is crucial for stability during searing.
- Dust Patties: Just before cooking, lightly dust both sides of the chilled patties with the 2 Tbsp of all-purpose flour.
- Sear Steaks: Heat the 2 Tbsp of canola oil in a heavy-bottomed skillet over medium-high heat until shimmering. Carefully place the floured patties into the hot oil. Sear for 4–5 minutes per side until deep golden brown and a beautiful crust (“fond”) has formed on the bottom of the pan.
- Remove and Rest: Once seared, remove the patties and place them on a wire rack or plate. Keep them warm while you transition to making the gravy.
- Sauté Mushrooms: Reduce the heat to medium. Add the 2 Tbsp of butter to the skillet. Once melted, add the sliced mushrooms and minced shallots/onion. Sauté for 5–7 minutes until the mushrooms have released their liquid and are deeply browned.
- Deglaze and Roux: Sprinkle the 2 Tbsp of flour over the mushrooms and fat. Stir constantly for 1 minute to cook out the raw flour taste (creating a light roux). Scrape up all the brown bits (the fond) from the bottom of the pan—this adds essential flavor to the gravy.
- Add Liquid and Seasoning: Slowly whisk in the 2 cups of beef stock until smooth and lump-free. Stir in the ketchup, the second tablespoon of Worcestershire sauce, and dried thyme.
- Simmer Gravy: Bring the gravy to a simmer, then reduce the heat to low. Let it bubble gently for 5 minutes until the gravy is thick enough to coat the back of a spoon. Taste and adjust seasoning with salt and pepper.
- Finish Cooking: Gently nestle the seared Salisbury steaks back into the simmering gravy. Cover the pan and allow them to finish cooking for 8–10 minutes, or until the internal temperature reaches 165°F (74°C).
- Serve: Garnish with fresh parsley (optional). Serve immediately, smothered in the rich mushroom gravy, preferably over mashed potatoes.
