Ingredients

  • 4 large portobello mushroom caps

Marinade

  • 1/3 cup olive oil
  • 1/4 cup balsamic vinegar
  • 1 tablespoon honey
  • 2 cloves garlic minced
  • 1 teaspoon kosher salt
  • 1 teaspoon dried rosemary
  • 1 teaspoon dried thyme
  • 1 teaspoon dried parsley
  • 1/4 teaspoon black pepper
  • 1/4 teaspoon red pepper flakes optional

Instructions

  • In a container, whisk together the ingredients for the marinade. Add the mushroom caps and flip a few times to make sure they are well coated. Refrigerate, covered, for 30 minutes. (Read my thoughts on marinating here.)
  • Preheat your grill. Turn all the burners on high and let the grill heat up for 15 minutes with the cover closed. After 15 minutes, turn the burners down to medium low.
  • Grill for 5 to 7 minutes on each side. Resist any urge to push down on the mushroom cap. They only need to be flipped once, and no other fussing.
  • Serve on their own or on buns with burger fixings.

Notes

Please note that nutritional information is does not include a bun and is based on the notion that at least half of the marinade will not be absorbed.
