Ingredients:
- 1 lb ground beef (80/20 lean-to-fat ratio)
- 1/3 cup Panko breadcrumbs
- 1 large egg, lightly beaten
- 1 tbsp Worcestershire sauce
- 1 tsp yellow mustard
- 1/2 tsp onion powder
- 1/2 tsp garlic powder
- 1/2 tsp fine sea salt
- 1/4 tsp black pepper, freshly cracked
- 1 large yellow onion, thinly sliced
- 8 oz cremini mushrooms, sliced
- 2 tbsp unsalted butter
- 2 tbsp all-purpose flour
- 2 cups beef broth, low sodium
- 1 tsp Worcestershire sauce (for gravy)
- Salt and pepper to taste
Instructions:
- In a large mixing bowl, combine the Panko breadcrumbs, egg, Worcestershire sauce, mustard, onion powder, garlic powder, salt, and pepper to create a paste.
- Gently fold in the ground beef. Mix just until combined to avoid overworking the meat. Shape into 4 oval-shaped patties, approximately 2 cm thick.
- Heat a large skillet over medium-high heat. Add the patties and sear for 4-5 minutes per side until a dark mahogany crust forms. Remove patties to a plate, leaving the rendered fat in the pan.
- Reduce heat to medium. Add the sliced onions and mushrooms to the skillet. Sauté until soft and golden brown, about 8 minutes, using the moisture from the vegetables to scrape up the savory brown bits (fond) from the pan.
- Stir in the butter until melted, then whisk in the flour. Cook for 2 minutes to remove the raw flour taste.
- Slowly whisk in the beef broth and remaining Worcestershire sauce.
- Return the patties to the pan. Simmer for 5-7 minutes or until the gravy has thickened and the steaks are cooked through. Season with salt and pepper to taste.
