  • 3 garlic cloves (peeled and minced)
  • 1 tablespoon grated onion
  • 1 teaspoon light brown sugar
  • 1 teaspoon Dijon mustard
  • 4 large portobello mushrooms (destemmed, rinsed, and dried)
  • ½ teaspoon kosher salt

  • 1 teaspoon kosher salt
  • 4 sliced pepper jack cheese
  • 2 cups chopped greens (arugula, spinach, romaine, etc.)
  • 4 sweet onion burger buns

  • ½ cup ketchup

Steps

  1. 1

    Add all of the marinade ingredients to a large bowl and whisk to combine.

  2. 2

    Dredge the mushrooms in the marinade a few times to coat them. Let the mushrooms marinate for 1 hour, flipping them halfway through.

  3. 3

    Preheat the grill to 400ºF and clean the grates.

  4. 4

    Place the onion rounds on a plate and drizzle them with olive oil and season them with salt and pepper.

  5. 5

    When the grill is heated, transfer onions to the grill over indirect heat. Grill the onions for 10 minutes, flipping halfway.

  6. 6

    Then, transfer the mushrooms cap side down on the grill over indirect heat. Grill the mushrooms for 3 minutes on the cap side, flip, and grill them for an additional 2 minutes.

  7. 7

    Place a slice of cheese on the mushroom and close the grill for 1 minute, allowing the cheese to melt. Remove them from the grill.

  8. 8

    While the mushrooms are cooking, combine the hummus and the ketchup in a bowl.

  9. 9

    Assemble the burgers. Place the bottom of the burger bun on a plate, and transfer ½ cup of the greens onto the bun. Top the greens with the mushroom patty, and top the patty with grilled onion rounds.

  10. 10

    Lastly, slather the top bun with 2-3 tablespoons of the hummus sauce to finish the burger. Serve immediately.
