Caramelized Onion Zin Burgers With Crispy Cheddar Frico Food

CRISPY BURGERS

Steps:

• Lightly mix together the sirloin, brisket, chuck, 1 1/2 teaspoons kosher salt, 1 1/2 teaspoons pepper and the garlic powder in large bowl with a fork until just combined.
• Divide the mixture into 6 equal mounds. Gently press each meat mound between two sheets of wax paper to make a thin patty, each about 4 inches wide and a little under 1/2 inch thick. (I used a tortilla press for this. If you don't have one, use a rolling pin.) Refrigerate until ready to use. The patties can be refrigerated for up to 1 day.
• Heat a cast-iron griddle or cast-iron skillet over high heat until very hot and smoking. Place each patty on the griddle and cook, undisturbed, until a deeply caramelized crust forms, 2 to 3 minutes. Using a spatula, carefully flip each patty and top with a slice of cheese. Continue to cook for 1 to 2 minutes longer until the cheese is melted and the desired doneness is reached.
• Meanwhile, brush the inside of each bun with melted butter and place on the griddle until toasted, about 1 minute. Place each burger patty on a bottom-bun half. Dress each bun top with ketchup, mustard, onion and pickles and flip on the the burgers. Serve immediately.
