The Perfect Bacon-Mushroom Burger
4 small portabella mushroom caps, roughly 3-inches in diameter or trimmed to 3-inches in diameter
Olive oil (about 2 tablespoons)
Kosher salt and freshly ground pepper
2 pounds fresh ground 80-percent lean chuck
1 (8-ounce) piece pancetta, cut into 1/2-inch pieces
4 Kaiser rolls, split
Unsalted butter, softened (about 2 tablespoons)
4 slices aged Swiss cheese
Preheat a grill for direct heat cooking and preheat the broiler. Rub the mushroom caps with the olive oil and season with salt and pepper. Place on the grill and cook, turning once, until softened, about 5 minutes. Cool.
Divide the beef into 4 equal amounts and working with one portion at a time, form into a very thin patty. Place the mushroom cap in the center and fold the beef up and around the mushroom pressing the beef around the edges of the cap until the mushroom is completely covered. Season the mushroom-beef patties generously with salt and pepper and place on the grill. Grill 4 to 5 minutes on each side for medium rare.
Meanwhile, cook the pancetta in a medium nonstick skillet over medium-high heat until crispy and transfer to a paper towel-lined plate to drain. Generously spread the butter on both sides of each roll and place under the broiler until toasted.
Place the cooked burgers on a rimmed cookie sheet and evenly top with the crispy pancetta bits and a slice of Swiss cheese. Place under the broiler until the cheese is just melted.
Build the burger by putting the patty on the bottom of a toasted bun. Add your favorite toppings and condiments then add the top half of the bun. Enjoy.
