INGREDIENTS:
1/3 cup breadcrumbs
1 egg lightly beaten
1 small yellow onion grated
1 teaspoon kosher salt for patties
1/2 teaspoon black pepper for patties
1 lb lean ground beef 90/10
1 tablespoon olive oil for searing
2 tablespoons butter for mushroom gravy
8 oz mushrooms sliced
2 tablespoons all-purpose flour for gravy thickening
2 cups beef broth for the gravy
1 teaspoon kosher salt to taste, for gravy
1/2 teaspoon black pepper to taste, for gravy
DIRECTIONS:
In a large bowl, combine breadcrumbs, grated onion, egg, kosher salt, and black pepper. Add ground beef and gently mix until just combined. Shape into four oval patties.
Heat 1 tablespoon of olive oil in a skillet over medium-high heat. Sear the patties for about 2 minutes on each side until browned. Remove the patties and set them aside.
In the same skillet, melt 2 tablespoons of butter and sauté sliced mushrooms for about 2 minutes. Sprinkle flour over the mushrooms and cook for 1 minute. Gradually stir in beef broth, bring to a simmer, and return the patties to the skillet. Simmer for 5-6 minutes until the gravy thickens and the patties are cooked through.
Serve the patties with mushroom gravy over mashed potatoes, rice, or egg noodles. Garnish with fresh parsley if desired.
