Delicious and easy! I sautéed mushrooms in avocado oil cause that’s all I had besides olive oil and I don’t have a broiler. In a salad or a sandwich just perfect! Thyme and basalmic vinegar with capers made such a great combo
Jennifer Castro
Loved this recipe! I added some rosemary and avocado and they were delicious!
Wanda Rice
Easy, easy. Tastes great. I’ll do this again instead of cooking on the stovetop. I feared my broiler would burn the shrooms but it didn’t, and they turned out perfect. Loved the mayo/capers dressing. I might tweak it a bit. Maybe maybe mayo, plain Greek yogurt and capers. That said, I love the recipe as is.

Following directions is difficult for me so I just put stuff on the indoor grill thing. Added some squash stuff, peppers and all that. Found some Kaiser buns and made them toasty. Pretty all together slapped a bunch of sauces and spices together but ultimately did use the idea of a sammich that was presented and it’s the awesomeness thing!
Julia Williams
Not too bad, this dish was very messy to eat even with thick buns. I figure the mushrooms would do better if they were cooked on a BBQ rather than the oven.
Daniel Carter
They were yummy, but I would back off the balsamic a little more.

Saved this recipe last week, and already made it 2 weeks in a row! So! Good!! And so easy! Only change I made was honey balsamic vinegar, because that’s what I had. Highly recommend this recipe – 2 thumbs up! Thanks for sharing!!
Shelly Harper
Great mix of flavors and a very quick and easy recipe to make.

SO good and SO easy. Thanks!! xo

I did not make any changes and my husband said he could eat these every day. I think I could, too. I do not have 2 setting on my gas broiler so next time I will maybe flip them twice instead of once and then check for doneness. I will also buy some better balsamic vinegar. Thanks so much.

This was a very flavorful sandwich. I have a personal aversion to the taste of vinegar so I replaced the balsamic with 1 tbs lemon juice and 1 tbs blackstrap molasses. Other than that I followed the recipe exactly and it turned out great.
Sarah Pace

Joanne Osborne

Julie Sutton
Great topped with a slice of mozzarella!
John Thomas
This recipe is easy and delicious . I did not have capers for the mayo and did without it. The buns got a little butter spread and finely grated parmesan prior to toasting on a cast iron skillet.
Amy Nichols
It was OK but I wouldn’t make again
Lisa Johnson
Pretty good
Carrie Ortiz
Best part about this recipe is the caper sauce! My son begs for it each time he sees the portabello mushrooms on the counter.
Brian Davis
These were awesome!! Will make these again and again!!!!!
Thomas Spencer
YESSSSS!!!!! These are fantastic! I added red onion and provolone, as several reviews recommended. I will have a hard time going back to regular burgers! My husband loved them, too! Thank you!
