Ingredients:

  • 1 lb ground beef (80/20 lean-to-fat ratio)
  • 1/3 cup Panko breadcrumbs
  • 1 large egg
  • 1 tbsp Worcestershire sauce
  • 1 tsp yellow mustard
  • 1/2 tsp onion powder
  • 1/2 tsp garlic powder
  • 0.5 tsp salt
  • 0.25 tsp black pepper
  • 1 large yellow onion, thinly sliced
  • 2 cups beef broth
  • 2 tbsp all-purpose flour
  • 1 tbsp butter
  • 1 tsp beef bouillon base

Instructions:

  1. In a large mixing bowl, combine the ground beef, Panko breadcrumbs, egg, Worcestershire sauce, mustard, onion powder, garlic powder, salt, and pepper.
  2. Mix with a fork until just combined, being careful not to overwork the meat. Shape into 4 equal-sized oval patties.
  3. Place the patties on a plate and chill in the refrigerator for 10-15 minutes to help them hold their shape during searing.
  4. Heat a large heavy-bottomed skillet over medium-high heat. Sear the patties until a deep brown crust forms on both sides (about 3-4 minutes per side). Remove patties and set aside.
  5. In the same skillet, melt the butter and add the sliced onions. Sauté until softened and lightly caramelized, scraping up the brown bits (fond) from the bottom of the pan.
  6. Sprinkle the flour over the onions and stir for 1-2 minutes to cook out the raw flour taste. Gradually whisk in the beef broth and bouillon base.
  7. Return the patties to the skillet. Simmer in the gravy for 5-10 minutes until the sauce has thickened and the beef is cooked through.
