This recipe comes from Ree Durmmond from food network. This will make about 14 burgers. Smashed burgers are great for kids parties.
3 1/2 pounds ground beef
Salt and black pepper
14 slices American cheese
14 small hamburger buns
Whatever you like on burgers
Divide the beef into 2 ounce portions and form into balls; you will have 28. Heat a large skillet or griddle over medium-high heat. Working in batches, place the beef balls on the surface and use a large spatula to smash them as flat as they can possible go. Sprinkle with salt and pepper. Cook for 2 minutes. Flip and immediately place a slice of cheese on half of the patties. Thirty seconds later, transfer the other patties onto the ones with the cheese. Wait a few seconds, then place on the buns. Keep going until you have 14 burgers. Serve with whatever you or your guests enjoy on burgers.
If you have older kids let them smash the burgers. It not only gives you a break, but it's fun for them also.
