  • Preheat grill for medium-high heat and lightly oil the grate.

  • Place red bell pepper onto the grate and grill until the skin is blistered and charred, turning often, about 10 minutes. Transfer pepper to a bowl and cover with plastic wrap; let pepper cool. When pepper is cool enough to handle, remove and discard skin, stem and seed the pepper, and chop.

  • Mix pepper into mayonnaise in a bowl and stir in cayenne pepper. Chill red pepper mayonnaise until serving time.

  • Grill marinated mushroom caps until browned and juicy, about 6 minutes per side. Serve mushrooms on buns, topped with red pepper mayonnaise.

YUM! The marinade gave the mushrooms a wonderful flavor. The mayo was great but a bit spicy for me so I'd reduce the cayenne next time but that's my preference. Instead of roasting a pepper I had a jar of roasted peppers and onions so I went w/ that...perfect! I served these on 'Soft Onion Sandwich Rolls' also from this site. I will be making these again! Thanks for sharing.:) Read More

Blech! Maybe I did something wrong because the other reviews seem to be great but the mushrooms soaked up so much of the marinade that all we could taste was the vinegar. The mayonnaise was good but I won't be trying these burgers again. Read More

This was excellent!!! However I didnt really measure the ingredients for the marinade and it turned out great. Also make sure to use a good quality balsamic vinegar it does make a huge differernce (no matter the recipe) a good balsalmic is on the thicker side. I also grilled slice beefsteak tomato slices on the grill and added a slice of sharp cheddar to compliment my shroom. Read More

My husband and I really enjoyed these. I liked the fact that it used simple ingredients I had on hand. The red pepper mayo was delicious. I also did not use as much cayenne as it called for. Just about 6 dashes and it was plenty hot. I could only marinate for 1 1/2 hours and the flavor was perfect. Read More

For those who felt the Balsamic was overpowering - I use White Balsamic almost exclusively. A bit lighter and doesn't seem as sweet. Many kinds available - I like the Peach. Read More
