Cheese-Stuffed Portobello Mushrooms

by simplylife on February 2, 2012

I used to be fearful of Portobello mushrooms.  Okay, all mushrooms.

I grew-up without ever seeing them on a plate and they never found their way into our kitchen.

I assumed I didn’t like them.

And then I started working at an upscale Italian restaurant during college.  Where we had to try each of the entrees that changed daily.

A college student being forced to eat well-prepared, free seafood, pastas, desserts and more.

It was rough.

Actually, it wasn’t.   At all.  I was given free soup, salad and coffee at all times, a generous discount on other meals, and most of all, the chance to try so many new foods!  I became much more adventurous in the way I ate and learned there were so many foods I always assumed I didn’t like that I really loved!

Portobello mushrooms fall in that category.  I love how versatile that are.  They can be chopped and used to enhance an appetizer.  They can be served plain, to accompany a piece of meat or seafood.  Or here, they can serve as a star, holding a medley of melted cheese and toasted breadcrumbs.

In other news, I was sent a this package from Garlic Gold that included a variety of their Garlic Nuggets!  The flavors included Southwest Blend, Sea Salt, Parmesan and Italian Herb.  We’ve tried the Southwest Blend with scrambled eggs and even sprinkled the Parmesan flavor over a bowl of air-popped popcorn.  Both flavors have been bold, flavorful and delicious! This is a great way to quickly add a lot of flavor to any dish!

    Yum! I usually do a sausage-pork stuffing but these would be a great change. I assumed I didn’t like oysters and sushi until I finally tried them… love them both.

  • Lauren

    these sound fabulous! 🙂

  • Beth

    Mushrooms and melted cheese are a magical combination!
    When I was a kid, I used to think I hated sweet potatoes. Now as an adult, they’re one of my favorite things to eat.

    • Simply Life

      Yes! Me too (about the sweet potatoes) 🙂

  • Kari

    I’m still a bit fearful of portobello mushrooms, just because I’m a novice at preparing them. You’ve reminded me to keep at it!

  • Meghan Smith

    Oh goodness I LOVE portobello mushrooms…these look amazing!

    I need to get myself a job like that ASAP 🙂

  • Michelle

    Oh. My. Goodness. These looks so delicious! I’ve never done much with mushrooms besides put them on salad.

    I know there are foods I’ve assumed I wouldn’t like and then did, but can’t think of one right now! Actually, I do know one. Growing up, I never ate sweet potatoes at thanskgiving because I thought they looked gross. WHAT WAS I THINKING?? I can’t believe how many years of yummy potatoes I missed out on.

  • Deepa

    Stuffed Mushrooms look simply perfect. I could almost smell them from here.

    How delicious! This is a great way to prepare portobellos. I’m so used to just grilling them like burgers.

  • Colleen

    Mushrooms are one of my favorite veggies! My old roommate used to call me “shroomie” instead of “roomie” because I liked them so much (and I still do!). This dish looks fabulous. And you have the best giveaways and products! So fun!

  • kyleen

    Working at an upscale Italian restaurant and trying all their food sounds like an awesome job! I too am not a huge fan of mushrooms, except when they’re on my deluxe pizza. But the stuffed portabellos look gorgeous! I’m especially fond of the cheese part.

  • Jamie

    Stuffed portabellas are one of my favorite foods! And this recipe looks great! Also, I have also worked at an upscale Italian restaurant but they DIDN’T allow us to sample the food! I’ve tried my family’s leftover pizza but throughout my entire time working there not once did I try one of the pastas, appetizers, or desserts that I talked others into buying!

    • Simply Life

      Oh that’s horrible! How could you give honest advice about what to order?!

  • Jolene (

    I have kind of assumed that I don’t like whoopie pies, but I have never tried one.

  • Lena @Fit on the Rocks

    I used to be afraid of mushrooms, too! The bigger, the scarier, but I love them now. The stuffed portobellas look fantastic

  • Rekha Shoban

    yum yum…looks great!

  • Melinda B

    These mushrooms look awesome. I am a huge mushroom fan, which is a good thing because I live in Japan and mushrooms are everywhere.

  • Sutapa

    They look so appetizing ….. fantastic way to prepare mushroom!

  • Anonymous

    Haha. Yes, there are loads of foods I didn’t think I liked, and then tried them as an adult and loved them. Mushrooms are one of those foods for me, and now I can’t get enough.

    Happy Friday!


  • Priya

    Seriously cant take my eyes from ur irresistible click,super tempting dish.

  • Amy (Savory Moments)

    These look delicious. I really enjoy stuffed mushrooms, especially with some cheese!

  • Joanne

    Hmmm now where can I find a job like that? Sounds right up my alley. 😛

    So do these portobellos…all that cheesy stuffing = heaven.

  • Heather

    I love portabello mushrooms – the are so meaty!

    Sounds like you had a great job in college – I would love a job like that now.

    Oddly enough, for the longest time, I hated rice. No idea why.

  • Rebecca

    When I was little, my mom cooked rabbit and I refused to try it. Now, I’ll try just about anything, and I love rabbit!

  • Kristen @ Swanky Dietitian

    I used to not be a big mushroom fan but have come around to them as well recently. They look amazing.
    I have been wanting to try Garlic Gold. I will have to keep my eyes out for it.

  • Shannon ~ My Place In The Race

    YESSSSSS!! Portabellos are amazing!! And I love Garlic Gold! So yummy 😛

  • Brittany

    I am fearful of mushrooms..the texture scares me. I do however want to try a portobello burger or THIS!

  • JoJo

    I used to not be a fan of mushrooms either..
    It’s so neat how your taste buds change over the years, and yes you never know what you dislike until you’ve tried it!

  • Charissa

    I had stuffed mushrooms at a restaurant the other day and they were amazing! Now I so want to try them, by making them at home!

  • Juniakk

    i love the idea of stuffing portabellas! the only hard part is eating it! it’s always so messy! this sounds more like “stuffing” stuffed in portabella mushrooms!

  • Kristy Gardner

    oooh the simplicity of this stuffed little ‘shroom is lovely. I have one that I make and I kind of throw everything in the fridge at it – this would be much quicker.

    PS. glad you converted. Mushrooms are where it’s at. Fo’ Sho’.

  • The Cookie Sleuth

    I love learning new ways to use portobello mushrooms. Yum!

  • Mom

    Sorry, if I didn’t like it, I basically didn’t use it to cook with! I have never tried so many things; mushrooms included! When I get my favorite steak dish, I order the mushroom sauce without the mushroom pieces!! I LOVE IT !! I never knew I would like oatmeal, sweet potatoes or grain ANYTHING !!! Your dish looks scrumptious and if I didn’t know mushrooms were the foundation, I’d probably bite right into them!!!

  • Emily @ A Cambridge Story

    If only I wasn’t terrified of mushrooms… the filling looks amazing though!!

  • Kiran @

    Love portobello mushrooms — so meaty, earthy and versatile 🙂

  • Ranjani

    I love stuffed mushrooms, especially when they are main dish material, like this!

  • Megha Sarin

    This looks so easy quick and even healthy <3


  • Karriann Graf

    Can I have a bite? They look fantastic!
