Ingredients

Ingredients
1 1/2 lbs ground beef
2 1/2 teaspoons Worcestershire sauce (divided use)
1 teaspoon kosher salt
1/4 teaspoon fresh ground black pepper
2 tablespoons butter (divided use)
1/4 cup finely chopped shallots or 1/4 cup sweet onion
4 button mushrooms, chopped
1/4 cup red wine (may substitute strong beef broth)
1 tbsp.dijon mustard
1 tablespoon lemon juice
1/2 cup heavy cream
2 teaspoons chopped chives (to garnish)

Preparation

Directions:
Gently combine ground beef, 1 teaspoons of the Worcestershire sauce, salt, and pepper. Form into 4 patties, each 1-inch thick.
Heat a large heavy skillet over medium heat. Add 1 Tbsp.of the butter and sear ground beef patties until browned on each side. Remove to a platter and keep warm.
Add remaining 1 tablespoons of butter to the same skillet along with shallots and mushrooms. Saute until most of the liquid has evaporated and vegetables are soft.
Carefully add red wine and stir often, scraping up browned bits, for 2 minutes until reduced. Stir in Dijon mustard, lemon juice, remaining 1-1/2 teaspoons Worcestershire sauce, and cream. Cook an additional 2 minutes. Taste and adjust salt and pepper, if need be.
Return beef patties, with any accumulated juices, to the sauce, turning to coat. Heat until warmed through, sprinkle with chives, and serve with pan sauce.
