Grilled Spinach Dip-Stuffed Portabella Mushroom Caps

September 11, 2014
Thank you to REAL® Seal for sponsoring this post ... and for encouraging us to not pack away those grills yet!  Sure, summer may have wound down.  But there's still time to get in some delicious late-season grilling.  To do my part in extending the grilling season, I whipped up these totally scrumptious Grilled Spinach Dip-Stuffed Portabella Mushroom Caps.

We all love spinach dip, right?  I mean, it's always the hit of the party.  Put out a bowl of the creamy spinachy stuff, and it's pretty much the first thing gone.  Always.  

So when the folks at REAL® Seal challenged me, as a REAL® Seal Dairy Diva, to incorporate dairy into a grilling recipe, I decided to turn to cheesy, creamy spinach dip.  Stuffed in a portabella mushroom.  Topped with a Parmesan-panko crumb topping.  And tossed on the grill.

And, oh man, ... it was good.

Wait.  You're not familiar with REAL® Seal??  Sure you are! We see its distinctive red seal all the time on dairy products.

And they show that the dairy products whose packages they grace are genuine American dairy products, made with milk from cows on U.S. dairy farms, and meeting strict manufacturing requirements. When you see the REAL® Seal on a dairy product, you can trust it’s the REAL thing.

When making these Spinach Dip-Stuffed Portabellas ... or any dish with dairy ... look for the REAL® Seal!

And then get movin' whipping these little beauties together.

Start by removing the gills and stem from beautiful big portabella mushroom caps.  I find scraping the gills with a spoon works pretty good.  To get up under the rim, I find a butter knife to be pretty handy in getting the job done.

Rub the cleaned caps with a touch of olive oil and sprinkle 'em with a bit of salt and pepper.

Then pop those babies on the grill ... inside down ... to get 'em cookin'.

Once the insides have cooked for a bit, flip the caps over and fill 'em up with a creamy, cheesy, spinach-dippy filling ...

... and sprinkle on a little Parmesan-panko crumb topping.

Let 'em hang out on the grill until the mushrooms are all tender and the filling is all warmed through.  Then get ready to dive into the best stuffed portabella EV-er.

And if you've already packed away that grill for the season, go get it out.  And extend the grilling season.  With spinach dip.  Stuffed inside your grilled mushrooms.  Enjoy!

  1. Love your recipe. Just want to know why you scrape inside of mushroom. Use these a lot in place of meat. Keep up good ideas. Thank you.

    1. So glad you like the recipe! You don't HAVE to scrape out the inside of the mushroom, but I do because the dark brown gills typically turn to a mushy texture when cooked and can turn to a pretty nasty color, neither of which I find appealing.

  2. Ohh pinning this for sure. It looks very much like one of my favorite dishes at Triumph Grill in St. Louis.
