Add the ground beef, breadcrumbs, eggs, salt and pepper and 1 teaspoon of Worcestershire Sauce to a large mixing bowl.
2 pounds lean ground beef, 2 large eggs, 1/2 cup Italian breadcrumbs, 1 teaspoon coarse kosher salt, 1/2 teaspoon black pepper, 2 teaspoons Worcestershire sauce
Using your hands mix the meat mixture until combined (don’t overmix though). Shape into rectangular(ish) shapes. Each steak will have about ½ - ¾ Cup of the meat mixture.
Add the olive oil to a large 12” (or bigger) skillet and heat over medium-high heat. Add the steaks and cook for about 3-5 minutes on each side, then remove to a plate. Drain any juices that came from the steak patties.
3 Tablespoons olive oil
Add the butter to the pan. Once it has melted, add the sliced onions. Cook for about 10 minutes, scraping up the stuck bits on the bottom of the pan, until the onions have softened. Add the minced garlic and cook for another 1-2 minutes, until fragrant.
4 Tablespoons salted butter, 1 large sweet onion, 4 cloves garlic
Add the sliced mushrooms and cook for 5 minutes, stirring occasionally until the mushrooms have released some of their liquid.
16 ounces brown mushrooms
Add the tomato paste and flour and cook for 5 more minutes while stirring occasionally to allow the tomato paste to caramelize slightly and the flour to lose its raw taste.
2 teaspoons tomato paste, 4 Tablespoons all-purpose flour
Slowly pour in the beef broth while stirring, then add the remaining Worcestershire sauce and vinegar.
5 cups beef broth, 1 teaspoon red wine vinegar
Add the steak patties back to the gravy and cook, covered, for 15 minutes, spooning the gravy over the tops of the steaks. Cook the salisbury steaks until they reach an internal temperature of 160°F when tested with a digital meat thermometer.
Sprinkle with chopped parsley (for garnish) then serve with mashed potatoes and favorite veggies.
