Grilled Portobellos With Pesto, Tomatoes and Feta

Many thanks to my dear friend Joanna who served these beautiful and oh-so-flavorful mushroom "steaks" for dinner the other night. I thought I had died and gone to Vegetarian Heaven! We had them as the main course, but they can also be served as an appetizer or on a sandwich/burger. Joanna made her own pesto with fresh basil, toasted pine nuts and extra virgin olive oil. Prepared pesto will work fine, but if you can, I suggest making your own for the best flavor. These are super easy and you can make them ahead of time and refrigerate till ready to grill. Serving size indicates number of mushrooms. As an appetizer, one mushroom per serving will do, but for a main course I would recommend 4 servings of 2 mushrooms each. The recipe originated in Vegetarian Times and I'm posting here for safekeeping.

Ingredients Nutrition


  1. Stir together pesto and olive oil, set aside.
  2. If desired, scrape off black gills under mushroom caps, and discard (the original recipe calls for this step but it is optional).
  3. Spoon 2 tablespoons pesto mixture into each mushroom cap and spread evenly.
  4. Gently mix feta cheese with diced tomatoes, and divide evenly to top each mushroom.
  5. If making ahead, wrap the topped mushroom in plastic wrap, and chill till ready to grill.
  6. Grill mushrooms over medium heat for 10 to 20 minutes, or until soft when pierced with knife. Serve hot and enjoy.

SOOOOOO good! Even my tomato hating sister loved it. The pesto makes it. I added some fresh chopped parsley and salt and pepper after grilling.

Mmmm! the taste of pesto tomatoes with the feta cheese is out of this world. I just sneaked a wee bit of chopped red pepper in also, I didn't bother with a bun and just served them with a side salad and they made a wonderful lunch, I also used a mix of italian herbs that you are supposed to use on focaccia bread but it was so tasty on these. very very nice Loof recommended them to me and am really pleased about that thanks Loof.Thank you for posting made for Honor thy Mother May 2011

Mmmmmm - great mushrooms! My mushrooms were huge so 1 per serving was plenty for us. I used Perfect Pesto (Raw Food) for the pesto and it was terrific. Perfectly grilled after the 20 minutes and just delicious - thanks for sharing this recipe!
