Now, this is more of a how to recipe rather than a precise one. I’ve not put any measurements in my recipe cos it’s really all about your taste. Feel free to use whatever sauce, seasonings and toppings you like. You can also keep it completley vegetarian or top it with chicken, bacon, pepperoni or your favorite pizza toppings.

  1. Portobello mushrooms
  2. Olive oil
  3. Salt & Pepper
  4. Garlic powder
  5. Pizza Sauce
  6. Mozzarella cheese
  7. Italian herb seasoning
  8. Red pepper flakes
  9. Toppings of choice (I used red pepper and chicken sausage)
  1. – Start by cleaning the mushrooms. To to do this, first gently pull out the stem by twisting and pulling on it. Then, scrape out the gills (optional, it’s not necessary) with spoon. Then wash the mushrooms clean (you can use a damp cloth, but I just prefer washing them) and pat them dry with some paper towels.
  2. – In the meantime get your grill going.
  3. – Generously drizzle some olive oil over both sides of the mushrooms and rub it around with your fingers.
  4. – Season the mushroom well on both sides with salt, garlic powder and black pepper.
  5. – Once your grill is heated and your ready to go, cook the mushrooms bowl side (cavity side) down for 7-8 minutes.
  6. – Then take the mushrooms off the grill and prepare the pizza part of this recipe.
  7. – Smother some pizza sauce into the mushroom cavity. Top with some fresh chopped basil and fill it up with some grated mozzarella cheese.
  8. – Next, sprinkle over some Italian herb seasoning and crushed red pepper flakes.
  9. – Then add whatever toppings you want on your pizza like sun-dried tomatoes, pepperoni, red pepper, onion, bacon…whatever you like really. I had some chicken sausage on hand so I used that with some red pepper.
  10. – Then place the mushrooms back on the grill (filling side up obviously) and cook the mushroom for another 8-10 minutes (with the lid closed) until the cheese is bubbly and melted.
  11. – Serve the pizzas hot with some fresh basil as garnish…mmmm!

    I found this recipe doing a Google image search for mushrooms on the grill. They were so good I had to come back and comment on how well they turned out. They even reheated well the next day. I have done mushrooms on the gas grill before, but these tasted so much better with hardwood charcoal. We did some without the pizza sauce and did a slice of tomato on top of the cheese and tasted great as well. Going to try these on our next camping trip!

      Thanks Dave…your comment is appreciated. :-) I love stuffing these bad boys with whatever I have on hand when we grill and I like saving them for the next meal. The charcoal really does add to the flavor!
