Recipe by: Bev Weidner, Bev Cooks

Ingredients

  • 3 tablespoons extra-virgin olive oil, divided
  • 1 yellow onion, thinly sliced
  • 1/2 teaspoon sugar
  • 1 pound lean ground beef
  • 1 (6-oz) wedge Roth Grand Cru® cheese, grated
  • 4 brioche buns, split and lightly toasted
  • 2 to 3 tablespoons stone-ground mustard
  • 1 avocado, sliced
  • Lettuce or red-leaf lettuce, for topping
  • Coarse salt

Method

  1. Heat 2 tablespoons oil in a large skillet over low heat. Add onions, season with sugar and a pinch of salt, cover and cook on low for one hour. Come back to it every 5 to 10 minutes to stir the onions, ensuring nothing is sticking. After an hour, they’ll be dark brown, shriveled and so beautifully sweet. Transfer to a cutting board and finely chop.
  2. Mix caramelized onions with the ground beef and season with a hefty pinch of salt. Form four quarter-pound patties or two half-pound patties.
  3. Add 1 tablespoon of oil to the pan and sear the burgers for four minutes over medium-high heat. Flip burgers, adding the grated cheese to the top of the patties, and sear another four minutes.
  4. Once the cheese has melted, assemble your burgers with mustard on the bottom bun, lettuce, the cheesy patty, sliced avocado and the top bun.
  5. Serve with roasted potatoes, if desired.
