Baby Portabella Sliders

I have had my eye on these babies for a while. Baby portabellas that is. As the name would suggest, they are smaller than a full grown portabella but a bit bigger than a cremini. So technically, they are really more of an adolescent portabella.


So, while that very important distinction has been made, the question what to do with them? remains.

Hmmmm. Slice and sauté or stuff like a cremini? No.

Marinate and grill like a big portabella? No.

More creative. Must be more creative.

They are the perfect size to replace the burger in a slider.

No, that’s not it either. Think. Think. Think.

Does anyone else out there have similar conversations with yourself?

Okay, yes, but do you have them about mushrooms?

Marinate and grill. Burger. Slider. I like it but not the burger. The bun? Oh, now that is intriguing.

The bun. Hmmmm. Sliders with baby portabella mushroom buns.

No bread, low carb, sounds delicious. I like it. I like it very much.

Baby Portabella Sliders it is!

Now, who else should we invite to the party?


Ahhhhh, blue cheese. My favorite party guest.


And applewood smoked bacon. Come on in!

Let’s get this party started!

Baby Portabella Sliders


Prepare slider sized burgers.

You can grill or pan fry them. Right now, it is about 482 degrees outside so I opted for the cast iron on my stovetop in my air-conditioned kitchen. If you are using ground beef at an 80/20 ratio, you don’t really need to do more to it than add a little salt and pepper. I had a leaner blend on hand so to one pound of ground beef, I added one egg as a binder and a dash of cream for moisture (about a tablespoon) along with a bit of freeze-dried parsley just for fun. Season on both sides with salt and pepper. As always, be sure your pan is good and hot before you put the meat in! I am a medium-rare kind of gal so I cooked the burgers on medium-high 4-5 minutes per side.


For the “buns”, I pulled the stems out of the mushrooms and then brushed both sides of the caps with Drew’s Rosemary Balsamic Dressing (I absolutely love the stuff) and seasoned both sides with salt and pepper. Use whatever dressing you like or even just a bit of olive oil or coconut oil.


I adore my cast iron grill pan and it worked perfectly for “grilling” up the mushrooms. Make sure your pan is hot before you put the mushrooms in. I cooked them on medium-high for 2-3 minutes a side. Don’t move the mushrooms after you’ve turned them and you will end up with perfect grill marks.

Now, to build the sliders.


I selected the least attractive mushroom caps to use as the bottom “bun” and set each on a leaf of butter lettuce. The sizes varied but still worked out just fine.


Next, the burger patty.


Blue cheese crumbles.


Applewood smoked bacon.


Just a bit of thinly sliced red onion.


And finally, the second mushroom cap. See those grill marks?


Buns? What buns? Who needs buns? Not when you’ve got baby portabellas!

These were delicious! The mushrooms were flavorful and juicy and perfect. Messy but perfect.

I can hardly wait to make them again. In fact, I can’t stop thinking about them.

Oh, the possibilities …

Ground lamb with feta crumbles and tzatziki. Maybe a little olive tapenade?

Smoked Cheddar. BBQ sauce. Jalapenos. Caramelized shallots. Garlic aioli. Brie. Pesto. Mozzarella. Roasted red peppers. Goat cheese. Avocados. Serrano ham. Monterey Jack. Pickles.

Infinite possibilities that beg the question … what are your favorite burger toppings?

I would loved to know!

    We were trying to get my grandson just this weekend to try mushrooms for the first time. He puts it on his tongue and spits it right back out…I guess he didn’t like the texture. But this grandma LOVES your recipe.

      I can’t think of too many kids who are mushroom fans. In fact, Nathan just ate the patty and the bacon. It is so fun to watch them try new things and their “disgusted” faces when it doesn’t go well. I didn’t like mushrooms as a kid either but now, I couldn’t live without them! And now I can’t live without these sliders. I hope you give them a try. 🙂

    Yum! These are right up my alley 🙂 I love marinated mushrooms grilled or roasted – and then you add blue cheese and bacon? I would happily eat these! Thanks for sharing 🙂

      It is so nice to drop the guilt and enjoy a really satisfying and delicious treat. The portabellas were so juicy and yummy, they really stole the show. And that is saying something when competing with blue cheese and bacon! Thanks so much for stopping by.

    I have to echo everyone else and say this is one awesome idea. Love it! by the way, did you change the looks of your blog? Everything looks so beautiful! The heading, the bee, etc.

      Thank you so much. The sliders were yummy and a fun twist. Yes, I did update the look – a little more summery and I love the bee too. My goal is to update the photos and background with the seasons but I didn’t quite get there for Spring. Better late than never! 🙂
