Fry up your bacon slices until they are crispy and set aside.
Make 4-5 oz golf ball sized meat balls using your ground beef.
Place each meatball onto a hot griddle or cast iron pan and smash them down to get your burger nice and thin.
Apply your salt, pepper, and garlic on the smashed side along with your diced white onion right on top.
After about 90 seconds flip your burger over and season the other side.
Add a slice of american cheese onto the burger patty until the cheese has melted on top and the burger is cooked all the way through to your preferred doneness. It will probably be another 90 seconds or so.
Toast your buns first by spreading a little butter on each side of the bun and placing them on your griddle. If there is enough fat on the griddle you can also run the buns through the fat instead of buttering the bread.
Once the buns are toasted, assemble your burger. I like to add the big mac sauce first on the bottom bun, then a few pickles, 1-2 burger patties, 2 slices of crispy bacon and more sauce, then the top bun.
