Ingredients

Scale
  • pounds ground beef (80/20 preferred)
  • ½ cup breadcrumbs (plain or seasoned)
  • 1 large egg, lightly beaten
  • 2 cloves garlic, minced
  • ½ cup beef broth (low-sodium preferred)
  • 1 teaspoon Worcestershire sauce
  • Salt and black pepper, to taste
  • 1 medium onion, thinly sliced
  • 8 ounces mushrooms, sliced (cremini or white button)
  • 3 tablespoons all-purpose flour
  • 2 cups beef broth
  • 1 tablespoon tomato paste (optional)
  • 1 teaspoon soy sauce
  • Salt and pepper, to taste
  • 2 pounds Yukon Gold potatoes, peeled and cubed
  • 4 tablespoons unsalted butter
  • ½ cup whole milk or cream
  • Salt, to taste
  • Freshly ground black pepper, to taste

Instructions

  1. In a large bowl, combine ground beef, breadcrumbs, beaten egg, minced garlic, Worcestershire sauce, salt, and pepper. Mix gently until just combined. Divide into 6 equal portions and shape each into an oval patty about ¾ inch thick. Wetting hands slightly helps prevent sticking.
  2. Heat 1 tablespoon oil in a large skillet over medium-high heat. Brown patties 3-4 minutes per side until nicely browned but not cooked through. Remove and set aside.
  3. In the same skillet, add sliced onions and mushrooms. Cook over medium heat until softened and golden, about 5-7 minutes. Sprinkle flour over veggies and stir to coat evenly.
  4. Slowly pour in beef broth, stirring constantly to avoid lumps. Add tomato paste and soy sauce. Bring to a gentle simmer and cook until gravy thickens, about 3-5 minutes. Season with salt and pepper.
  5. Transfer browned patties to slow cooker. Pour mushroom-onion gravy over patties, ensuring they are covered. Cover and cook on low for 4-5 hours or on high for 2-3 hours until patties are tender and gravy is rich.
  6. While steaks cook, place peeled and cubed potatoes in a large pot. Cover with cold water, add a pinch of salt, and bring to a boil. Cook until potatoes are fork-tender, about 15-20 minutes. Drain well.
  7. Return potatoes to pot or warm bowl. Add butter and warm milk or cream. Mash until smooth and creamy. Season with salt and pepper. For extra fluffy potatoes, use a ricer or hand mixer.
  8. Serve Salisbury steaks and mushroom gravy over creamy mashed potatoes. Garnish with fresh parsley if desired. Enjoy immediately.

Notes

[‘Browning the patties before slow cooking locks in flavor and juices.’, ‘Use fresh mushrooms for better texture and flavor.’, ‘If gravy is too thin after cooking, thicken with cornstarch slurry and cook on high for 10-15 minutes.’, ‘Avoid overmixing the meat to keep patties tender.’, ‘Warm milk or cream before adding to mashed potatoes for creamier texture.’, ‘Can be cooked in a Dutch oven on stovetop for 1.5 to 2 hours as an alternative to slow cooker.’, ‘For gluten-free, substitute all-purpose flour with gluten-free flour blend.’, ‘For a lighter mashed potato, use almond or oat milk instead of whole milk.’]
