Roll your ground beef into balls (about ⅓ of a cup of meat per ball) and set to rest in the fridge. Place 1/2 a bulb if garlic in tin foil, add a pinch of salt and 1 tsp of olive oil and roast. Once the cloves are golden brown and soft, remove from the oven. Let your garlic cool slightly, and add to 1 cup mayo with 1 tsp salt and 1 tsp pepper.
With a sharp knife or a mandolin, slice ½ and onion. Set aside.
Place a large frying pan over medium-high heat. Once the pan is hot, place a ball into the center. Place ¼ of the shaved onions on each ball. With a flat metal spatula and a small square of parchment, press down on the burger. Season generously with salt and pepper. Cook for 3-4 min on both sides. Add a slice of cheese once flipped.
Toast you buns, add mayo, tomato, pickles, two patties and enjoy! I serve mine with roasted sweet potato wedges and extra garlic aioli!
