Ingredients:
- 1 lb lean ground beef (90/10)
- 1/4 cup plain breadcrumbs
- 1 large egg, beaten
- 1 tbsp Worcestershire sauce
- 1 tsp Dijon mustard
- 1/2 tsp garlic powder
- 1/2 tsp salt
- 1/4 tsp black pepper
- 2 tbsp olive oil
- 8 oz baby bella mushrooms, sliced
- 1/2 medium yellow onion, finely diced
- 2 cloves garlic, minced
- 1 tbsp tomato paste
- 2 cups low-sodium beef broth
- 2 tbsp cornstarch
- 2 tbsp cold water
- 1 tsp fresh thyme or parsley, chopped
Instructions:
- In a medium mixing bowl, combine the lean ground beef, breadcrumbs, egg, Worcestershire sauce, mustard, garlic powder, salt, and pepper. Mix until just combined and shape into four oval-shaped patties, approximately 3/4 inch thick.
- Heat olive oil in a 12-inch skillet over medium-high heat. Sear patties for 3-5 minutes per side until a mahogany-colored crust forms. Remove patties from the pan and set aside on a plate.
- In the same skillet, sauté the sliced mushrooms and diced onions until the onions are translucent and mushrooms are browned. Stir in minced garlic and tomato paste, cooking for 1 minute.
- Pour in the beef broth and bring to a simmer. Whisk in the cornstarch slurry (cornstarch and water) and stir until the sauce thickens and becomes glossy.
- Return the seared patties and any accumulated juices to the skillet. Spoon gravy over the meat and simmer on low heat for 5 minutes until the internal temperature reaches 160°F. Stir in fresh thyme or parsley before serving.
