Step-by-step instruction without your screen going to sleep

  • 1 large white onion, peeled, sliced
  • 1 tablespoon canola oil
  • 1 packet (1.2oz) French onion soup mix
  • 1 pound 80/20 ground beef
  • Kosher salt, as desired
  • ground black pepper, as desired
  • 6 slices Swiss cheese
  • 6 brioche hamburger buns


  • Large Bowl
  • Flipping spatula
  • Step 1

    To install the griddle plate, position it flat on top of the heating element and gently press down until it sits into place. Close the hood.

  • Step 2

    While holding the smoke box lid open, use the pellet scoop to pour pellets into the smoke box until filled to the top. Then close the smoke box lid.

  • Step 3

    Turn dial to GRILL, press WOODFIRE FLAVOR, set temperature to HI and set time to 15 minutes. Select START/STOP to begin preheating (preheating will take approx. 15-19 minutes).

  • Step 4

    While the unit is preheating, to a large bowl add the ground beef, onion soup mix, salt, and pepper and mix until fully combined. Shape mixture into 2 balls 3 ounce each and place into refrigerator until ready to use.

  • Step 5

    When unit beeps to signify it has preheated and ADD FOOD is displayed, open hood, add oil to the griddle, then add the sliced onions. Close hood and cook for about 5 minutes.

  • Step 6

    After 5 minutes, open hood and toss onions.  Remove the meatballs from the refrigerator, then place on the griddle plate surrounded by the onions. Lightly spray the underside of a flipping spatula with non-stick cooking spray and firmly “smash” each ball into a thin patty and season with salt and pepper. Close hood and cook the burgers for about 2 to 3 minutes per side.

  • Step 7

    Open hood and add a slice of cheese to each burger, close hood and cook for 1 minute or until cheese is melted.

  • Step 8

    When cooking is complete, add patties to burger buns as single burgers or with two patties for double burgers, ensuring each burger has an ample amount of onions.
