These gourmet beef burgers are paired with a creamy horseradish sauce and fresh greens for a delightful meal.
In a mixing bowl, combine the sour cream, applesauce, horseradish, chives, salt, and pepper. Mix well and refrigerate.
Chill the sauce for at least 15 minutes to let the flavors meld together.
In another bowl, mix the ground beef, Worcestershire sauce, parsley, salt, and pepper. Form into 4 equal patties.
Make a small indentation in the center of each patty to prevent it from puffing up during cooking.
Heat a skillet over medium-high heat. Cook the patties for 4 minutes on each side for medium doneness.
Avoid pressing down on the patties while cooking to retain their juices.
Toast the burger buns lightly in the skillet or toaster.
Toasting the buns adds a nice crunch and prevents them from getting soggy.
Assemble the burgers by placing watercress on the bottom bun, followed by a patty, a generous dollop of horseradish sauce, and the top bun.
Serve immediately for the best taste and texture.
