Ingredients

Instructions

  • Clean portobello mushrooms with a damp cloth. Remove stems using your fingers or a knife.
    If you'd like, use a spoon to remove the dark brown gills from underneath the mushroom. They don't affect the flavor at all, but they do release dark brown liquid while they cook.
  • In a mixing bowl, combine olive oil, red wine vinegar, minced garlic, dried parsley, dried basil, dried oregano, a generous pinch of salt, and a dash of pepper. (For the garlic, I like to use a Microplane zester, so that it's almost paste-like & easy to combine with the other ingredients.)
  • Add the mushroom caps to the mixing bowl. Use your hands to make sure that each cap gets covered front & back with the marinade. If your mushroom caps are especially large, you can add more oil if needed to make sure it's all evenly dispersed.
  • Put the bowl with mushrooms in the refrigerator, and let them soak in the marinade for 30 minutes to an hour. (If your refrigerator isn't large enough to hold a mixing bowl, the mushrooms can go into a freezer bag instead to marinate.)
  • Bring a grill, fire pit with grate, or grill pan to a medium high heat. (For a gas grill, I aim for about 500 degrees.)
  • Put the marinated mushroom caps on the grill, grate, or grill pan. Cook for about 4 minutes on each side & then flip. (Don't flip until the mushrooms have nice grill marks.) Remove from heat & serve.
