Step 1
In a large bowl, combine the ground sirloin, salt, pepper, garlic and onion powder until evenly combined. Divide the mixture into 4 equal parts and then shape each into thin square patties. Place on a baking sheet lined with parchment paper and freeze for 30 minutes.
Step 2
Heat a large griddle or cast iron skillet over medium-high heat. Once hot, place the frozen meat patties on the pan. You might have to cook them in batches. Press down with a spatula and cook for about 4 minutes on the first side. Flip over and cook for another 2 to 3 minutes on the second side. Turn off the pan and place a slice of cheese on top of each patty and allow to melt.
Step 3
Toast the buns and place the remaining cheese slices on top of the bottom buns. To assemble the burgers, place a burger patty on top, lettuce, tomato, onion, and pickles. Spread the top buns with mayo and ketchup and place on top of the burgers. Serve immediately.
