  1. Place the mushroom caps, smooth side up, in a shallow dish. In a small bowl, whisk together vinegar, oil, basil, oregano, garlic, salt, and pepper. Pour over the mushrooms. Let stand at room temperature for 15 minutes or so, turning twice.
  2. Preheat grill for medium-high heat.
  3. Brush grate with oil. Place mushrooms on the grill, reserving marinade for basting. Grill for 5 to 8 minutes on each side, or until tender. Brush with marinade frequently. Top with cheese during the last 2 minutes of grilling.

This recipe is excellent. However, I don't have a grill so the first time I broiled them on a cookie sheet with tin foil. They came out great, but I found that the marinated made them slightly runny. Next time I made them I placed them on a wire rack with a cookie sheet under it and broiled it for the same amount of time - about 5 minutes on both sides. Came out fantastic! Update: I've made these burgers so many times now, they're that good. To add some extra flavour, chop 2-3 onions and sauté them for at least 20 minutes on low heat with olive oil and butter. Viola, caramelized onions, which taste AMAZING with these burgers. One final note for those who didn't like the vinegar taste: a good balsamic is essential. The cheap stuff (under 5 bucks) is gross and overpowering. Buy a good bottle (you'll use less) and it tastes much sweeter.


Wow! The cheese really makes this a treat. I tried grilling this on my Foreman grill for just a few minutes, and it comes out perfect!


Honestly, as a real meat lover, I could replace hamburger forever with grilled portobello! The taste is beyond belief. Simplified things a bit, as some men might. Just used a dish of olive oil, added a dash of salt and pepper and brushed it on. I also did the same to 1/2" thick cuts of onion and grilled them side by side (onions a little longer of course). When they were both finished, I topped the mushroom with the thick cut onion and topped that with provilone. What a surpise I am telling you. Good luck and Thank you!
