Instant Pot Salisbury Steak is a delicious and comforting recipe that cooks easily in the pressure cooker. Serve over noodles or mashed potatoes for a delicious weeknight meal.
In a large mixing bowl, combine 1½ pounds lean ground beef, ½ cup breadcrumbs, 1 large beaten egg, ½ teaspoon salt, ½ teaspoon black pepper, and 1 tablespoon Worcestershire sauce. Mix until just combined and divide the mixture into 6 equal patties.
Heat a large skillet over medium-high heat. Brown the patties for approximately 3 minutes per side. Do not cook them all the way through.
Place ½ sliced onion and 4 ounces sliced mushrooms in the bottom of the Instant Pot.
In a medium bowl, whisk together 1 package brown gravy mix, 2 cups beef broth, 1 tablespoon Worcestershire sauce, and 1 teaspoon Dijon mustard.
Seal and cook on high pressure for 15 minutes. After the cook time, do a quick release to release the pressure from the instant pot by moving the valve on the lid from the sealing to the venting position.
Remove the patties from the instant pot and set aside.
Switch the instant pot to the sauté setting. In a small bowl, whisk together 2 tablespoons cornstarch and 2 tablespoons cold water until smooth. Stir this mixture into the instant pot. Cook, stirring constantly, for 3-5 minutes until the sauce thickens. Turn the instant pot off and add the beef patties back to the instant pot.
Serve over mashed potatoes and enjoy!
