Serves – 4                           Total Time - 30 Minutes

This recipe could make a great hand-held appetizer, vegetarian entrée or as part of a sandwich.

Tip – Removing the black gills out of the mushroom before marinating can really help with the end presentation.  You can use a spoon to scrape them out.


  • 2 Cedar Grilling Planks
  • 4 Portobello Mushrooms, stems and gills removed
  • 4 Tbsp. Olive Oil
  • 2 Tbsp. Balsamic Vinegar
  • 4 ½ slices fresh Mozzarella
  • 1 large Tomato
  • 1 Zucchini, sliced
  • Basil leaves
  • Coarse Salt and Pepper


  1. Soak the planks in hot water for at least 15 minutes and preheat the grill or oven to 400°F.
  2. Place the mushrooms in a bowl with the oil and vinegar, allow to marinate for up to an hour.
  3. Place a slice of mozzarella, tomato, and zucchini in each mushroom cap.
  4. Drizzle with some of the marinade, season with salt and pepper.
  5. Set the mushrooms on the planks and place them on the grill or in the oven.
  6. Cook for 15 minutes or until the mushroom is soft and the cheese has melted.
  7. Garnish with fresh basil leaves and serve hot.
