Separate the ground beef into 4 equal parts and loosely pack into round balls.
Light the Blackstone griddle to medium heat & allow it to heat up for a few minutes.
Place the burgers on the grill. Mine tends to heat up more toward the top of the grill, and I put them on the hottest portion for a nice crust. Take a slice of parchment paper and place on a burger and use the burger press to push down the ground beef ball into a flattened burger. Repeat with all 4 burgers (Watch the video to see the process).
Add salt and pepper to each burger.
Once they get nice and crispy, flip the burgers. They only cook for a few minutes (between 2 and 3).
Cook for another 2 to 3 minutes and transfer to the cooler portion of the grill. Add the cheese and allow it to melt for a minute or two.
Optional: If you are cooking the onions and brioche buns, add the butter to the griddle on medium heat and cook the onions for about 4 to 5 minutes, tossing every minute. Place the brioche buns inside down for just 30 seconds to 1 minute to toast them.
