  • 1 pound lean ground beef grass-fed
  • 3 slices bacon hormone/nitrate-free
  • 1 large egg
  • 1 tablespoon worcestershire sauce
  • ½ teaspoon garlic powder
  • ½ teaspoon salt
  • ¼ teaspoon pepper
  • 3 portobello mushrooms
  • 3 ounces Black Creek® Extra Sharp Cheddar cheese sliced or crumbled
  • 1 avocado sliced


  • Let ground beef sit at room temp 20-30 minutes. Preheat gas grill to medium-high heat or prepare coals if using charcoal.
  • Cook bacon in non-stick pan over medium-high heat until crisp, 2-3 minutes per side. Drain and set aside. Alternately you can cook them on grill with burgers.
  • In a medium bowl mix together ground beef, egg, worcestershire sauce, garlic powder, salt and pepper. Form into 3 patties, about ¾-inch thick.
  • Place burger patties and mushrooms on lightly greased grill and cook 4-6 minutes, until sear marks form on bottom. Reduce heat to medium and flip items. Cook about 5 minutes longer or until seared, mushrooms are tender and burgers reach and internal temp of about 150° F for medium. Top each burger with desired amount of cheddar right before end of cooking and melt.
  • Place burger patties on mushrooms and top with avocado and cooked bacon.
