Directions

Preheat the oven to 250 degrees F. Preheat a griddle to 350 degrees F.

Combine the onion powder, garlic powder, pepper, and salt in a small bowl. Set aside.

Line a jellyroll or sheet pan with parchment paper, and place the ground chuck in the middle of the pan. Cover the meat with a large sheet of plastic wrap. Roll meat with a rolling pin until it covers the surface of the pan; it should be very thin. Remove the plastic wrap, and sprinkle the meat with the seasoning mixture. Fold the meat in half, from side to side, using the parchment paper. Use a pizza wheel to cut the meat into 8 even squares.

Wrap the buns in foil and place in the oven for 5 to 10 minutes. Meanwhile, place the burgers on the griddle and cook for 2 to 3 minutes per side.
