Beef-Mushroom Smash Burgers Prenotes Ingredients: 1 1/2 pounds ground beef 8 ounces cremini mushrooms, trimmed and minced in a food processor Kosher salt and freshly cracked pepper 1 to 2 tablespoons unsalted butter 8 slices American cheese 4 brioche buns 2 cups shredded green leaf lettuce Procedures: In a large bowl, combine the beef and minced mushrooms. Divide the mixture into 8 balls, about 4 ounces each. Season with salt and pepper on both sides. Heat a large cast-iron skillet or griddle over medium-high heat. Add the butter. Once the skillet is very hot and the butter has melted, add the beef balls (you may need to do this in a few batches, depending on the size of your skillet or griddle). One at a time, place a burger press over each beef ball (you may want to place a small sheet of parchment on the meat in case the press sticks). Smash each burger into a flat disk for 10 seconds, applying a lot of pressure. Repeat until all the burgers are smashed. Cook the patties 2 minutes, then flip. Sprinkle with salt and pepper and press down again with the press. Continue to cook until caramelized and charred, 1 to 2 more minutes. Top each patty with a slice of cheese and let melt, 1 to 2 minutes. Top with some shredded lettuce and 2 patties. Close with the bun tops and enjoy!
