Blackstone Smash Burgers

My favorite type of burger is a smashed burger or thin burger. Whatever you like to call it. They fit on the bun nicely and the toppings are easy to put on and they STAY on.

Ingredients

  • 2 teaspoon olive oil
  • 2 teaspoon butter
  • 2 cups thinly sliced onions
  • ¼ teaspoon kosher salt
  • 1 lb lean ground beef 93%
  • 4 slices Sharp Cheddar Cheese Slices
  • 4 pieces lettuce leaves
  • 4 hamburger buns

Instructions

  • Preheat your Blackstone griddle to high heat.
  • On one side of the griddle add the olive oil and butter, and let it heat for about a minute.
  • Add the onions to the griddle, and sprinkle with salt and pepper. Use a spatula to toss the onions frequently to prevent sticking and ensure even cooking.
  • Continue cooking the onions on the griddle for about 20-25 minutes, or until they are soft and caramelized to your liking.
  • Divide the ground beef into 4 equal portions and form into balls.
  • Season each ball with salt and pepper on both sides.
  • Place a ball onto the griddle and smash it down with a spatula until it's about ¼ inch thick.
  • Repeat with the remaining balls and leave them on the griddle for about 2-3 minutes until the edges start to brown and the burgers release from the griddle.
  • Flip each burger and add a slice of American cheese on top.
  • Let the cheese melt for about 30 seconds.
  • While the cheese is melting, butter the brioche buns and place them on the griddle until they are toasted.
  • Assemble the burgers with the buns and your desired condiments.
