I made this on Saturday and have been dying to tell you about it ever since! There is just something about the Portabella for me at the moment. I don’t know what it is but the big caps just look so appetizing at the grocery store. I’ve been picking them up and experimenting. First was the Cheddar Pepper Stuffed Portabello Burger which was super yummy but then I had lunch with a fellow "Foodie" and we both ended up ordering the same thing, a Portabella panini with red onion and roasted peppers.
It was DIVINE! 
Of course it was served on two THICK slices of white bread drenched in butter (completely unnecessary) but that’s not why I liked it. It was the combo of sweet pepper, red onion and earthy Portabella that I fell in love with. So I set out to recreate my own version.
This is what I came up with.
- 2 large Portabella caps cleaned and stems removed
- 1-2 thin slices of red onion
- 3/4 ounce of a mild cheese like Muenster- I used Mini Babybel Bonbel round, perfect!
- 2 roasted red pepper – I used the jarred piquillo kind
- Sprinkle of kosher salt, garlic powder and dried thyme
Here are the base ingredients. So pretty. :)

Heat your George Forman or Panini Press. You could do this in a skillet but you would need to press down while cooking and then flip.
I sprayed a bit of non-stick spray as my grill is old. Place one Portabella upside down, layer on the sliced onion, then cheese, peppers and finally spices.

If you are using a Laughing Cow round, simply cut it into three slices and scatter them on the cap. You can see my three sticking out in the picture above.
Top with the second Portabella cap and press. Now, if you are using the George Foreman like me, make sure to account for the shifting that will occur. When closing the top the grill will want to slide the top layer off. Just offset before closing and hold it in place with your finger.

Cook for about 5 minutes. Since I was using my foreman grill after 2 and half I rotated the mushroom around as it does cook uneven favoring the back. You would not have to do this in a traditional panini press.
Remove and wonder at your glorious creation! (ok, you don’t have to, it’s just what I did) ;)

Here’s what the middle looked like…

Little man wanted NOTHING to do with it but he loves getting involved with the picture taking aspect of my food blogging obsession. His contribution was the red heart balloon which I thought was quite fitting. lol

I *wish* I liked mushrooms! This looks so beautiful and delicious.
this looks awesome… I LOVE using portobellos in (or as!!) a sandwich… YUM.
There’s no way my son would eat this either, but my husband liked portabellas. Bookmarking this!
Yum, that looks really good.
This sounded so awesome that I sent my boyfriend on a special trip to the grocery store on his way home from work.
Fail #1: The sandwich is too tall for my George Foreman to close on it. Switched to grill pan.
Fail #2: Due to slippery roasted peppers, could not keep the burgers from sliding apart, thus burning the basil (which I’d used instead of onions). Finally managed after many vulgarities to get them to stay put.
Fail #3: Mushrooms started to burn long before cheese melted. When I had to take them off the burner, I opened one up and the inside of the mushroom was still cold.
Finally just chopped everything into bite-sized chunks and sauteed it until it was evenly cooked. Toasted some homemade bread and put it on top of that for an open-faced sandwich.
*sigh*
Looooooooks A-MAZING!!!! Can’t wait to try it!
Oh NO E!
I’m sorry you had so may problems! I’ll tell you what.. I’ll try to make it again on video so you can see how I used the forman. It was a little tricky which is why I showed the inside view.
Hope you’ll be willing to try it again!
The taste was good… I just wish I could have gotten them to be actual burgers. :(
That is what I’ll focus on. Just technique. I was looking for another reason to make it again anyway. ;)
This looks delicious, Roni! Can’t wait to try it!
Instead of a panini press or grill….is it possible to use a waffle iron??
This sounds amazingly good! I need to get myself a panini press!
The perfect sandwich!
Hope this helps E!

I made it for lunch and it was amazing. I used laughing cow cheese and spinach onions and red peppers.
Great idea…thanks.
P.S. this blog is amazing…i’ve already emailed myself three recipes to try at home…

LOVE IT!!! I am making this one this weekend for sure. I just love portobella mushrooms and red peppers. Does it get any better than this. Thanks for the fantastic idea. I loved the last portobella recipe you created. OMG it was the best. Keep them coming.
Good, but veryyy messy!!
Mine didn’t look as good as yours though.
i changed it up a little bit though, i didn’t have red onions or roasted red peppers so i used a tomato slice and baby spinach, and a laughing cow light swiss cheese wedge.
I’m sure it was! Tomatoes have even MORE moisture!
Oooo! Tomato! I was just going to ask if anyone has an alternative to red peppers! ( Blech!! You all may have my share!) Spinach and cheese would be awesome! Zucchini just occured to me too!
I would be inclined to seed the tomato first.Hopefully that would cut down on some goo. As I have 1, lonely portobello, I shall have to make it 1/2 sized….( but it’s a MONSTER!)
yes spinach and cheese very good!
i added baby spinach to mine :)
OMGosh, I just made this for dinner and it came out so delish!!!!!!! I am a garlic fan so I added minced garlic to the sandwhich. Thanks for the recipe, I absolutely love this.
I’v never tried peppers out of a jar before, I always assumed they were in oil and therefore a no no! I’v now discovered that they are low cal, and therefore I am hoping to make this in the next few days!
These were incredible! I made two at once and they came out great! Thanks for the recipe and video hints.
I have always wanted to try this particular type of mushroom, will definitely pick up the ingredients on my next grocery store trip.
when i saw this i HAD to try it… today i did and it is truly AMAZING!!! i wish i could post my own picture of it… thankyou soooooooo much for this idea
