Ingredients

Scale
  • 1 1/2 pounds ground beef (80-85% lean)
  • 1/2 cup plain or panko breadcrumbs
  • 1 large egg
  • 1 tablespoon Worcestershire sauce
  • 1 teaspoon Dijon mustard (optional)
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon onion powder
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 2 medium yellow onions, thinly sliced
  • 8 ounces cremini or white mushrooms, cleaned and sliced
  • 2 cups low-sodium beef broth
  • 3 tablespoons butter, divided
  • 2 tablespoons all-purpose flour
  • 1 teaspoon fresh thyme (optional)
  • Salt and pepper to taste
  • 4–6 slices Swiss cheese (about 3.5 ounces total, thick-cut preferred)

Instructions

  1. Prep the ingredients: Thinly slice onions, clean and slice mushrooms, and shred or slice Swiss cheese if needed.
  2. In a large mixing bowl, combine ground beef, breadcrumbs, egg, Worcestershire sauce, Dijon mustard, garlic powder, onion powder, salt, and pepper. Mix gently until just combined.
  3. Shape the mixture into 4-6 oval or round patties, about 3/4-inch thick.
  4. Heat 1 tablespoon butter in a large skillet over medium-high heat. Sear patties for 2-3 minutes per side until browned (they do not need to be cooked through). Transfer to a plate and tent with foil.
  5. Lower heat to medium. Add 1 tablespoon butter to the pan, then add sliced onions. Sauté for 3-4 minutes, scraping up browned bits. Add mushrooms and cook another 4-5 minutes until golden and soft.
  6. Sprinkle flour over onions and mushrooms. Stir and cook for 1 minute. Slowly pour in beef broth, whisking constantly. Add fresh thyme if using. Bring to a simmer and cook until slightly thickened, about 2-3 minutes.
  7. Nestle seared hamburger steaks back into the gravy. Spoon sauce over the top. Cover and simmer gently for 8-10 minutes, or until patties are cooked through (internal temp 160°F).
  8. Turn off heat. Place a slice of Swiss cheese on each patty. Cover the pan for 1-2 minutes until cheese is melted.
  9. Serve hamburger steaks hot with plenty of mushroom onion gravy.

Notes

For gluten-free, use gluten-free breadcrumbs and flour or cornstarch. Don’t overmix the beef for tender patties. Let patties sear undisturbed for best browning. Gravy thickness can be adjusted with more or less broth. Leftovers keep well and flavors deepen overnight. Try provolone or cheddar if you don’t have Swiss cheese.
