Steps

• 1

  Make the caramelized onions. In a large sauté or frying pan over medium heat, heat 2 tablespoons of olive oil. Add the onions and a generous pinch of salt. Cook, stirring often until the onions start to caramelize and break down.

• 2

  Reduce the heat to low and continue to cook, stirring frequently until the onions are very brown and sweet, 25-30 minutes. Taste, adding more salt if necessary. Use immediately, or allow to cool and store in an airtight container in the refrigerator for up to 3 days.

• 3

  When ready to cook, set the Traeger temperature to 400°F and preheat with the lid closed for 15 minutes.

  Make the burgers. In a large bowl, add the ground beef and season with 2-4 teaspoons of kosher salt, and 1 teaspoon of ground pepper. Using your hands, gently mix the ground beef to incorporate the salt, making sure not to overwork it.

• 5

  Shape the beef into 2-3 oz burger patties. Brush both sides of the patties with a small amount of oil.

• 6

  Place the burgers directly on the grill grates. Close the lid and cook for 2-3 minutes, then flipping and cooking an additional 2-3 minutes until you reach desired doneness. If using cheese, add the cheese when the burgers are flipped.
