A delicious burger with all the ingredients packed inside, mixed in with the ground beef. Ingredients:
1 teaspoon butter |
1 cup finely chopped red onion |
3 pounds ground beef |
1 cup chopped mushrooms |
1/2 cup ketchup |
4 egg yolks |
1/4 cup worcestershire sauce |
2 tablespoons horseradish mustard |
4 teaspoons ground black pepper |
1 tablespoon sea salt |
Directions:
1. Heat butter in a skillet over medium heat and cook and stir red onion until soft and translucent, about 5 minutes. Mix ground beef, cooked onion, mushrooms, ketchup, egg yolks, Worcestershire sauce, horseradish mustard, black pepper, and sea salt in a large bowl until thoroughly combined.
2. Form the mixture into six 3/4-inch thick patties and cook in a large skillet over medium heat until burgers are juicy and browned, 5 to 7 minutes per side. An instant-read meat thermometer inserted into the center of a patty should read at least 160 degrees F (70 degrees C).
