Cedar Planked Grilled Portobellos Stuffed with Summer Veggies

Sharing is caring!

I normally use grilling planks for salmon or scallops but this time I thought I would try using vegetables, in particular big “meaty” portobellos!
Make sure you buy natural untreated wood that is free of chemicals, strictly sold for cooking, You wouldn’t want to use just any old type of wood from a hardware store, it could be very toxic!

 There are various cooking woods on the market, some of my favorites as well as the cedar are maple, cherry, alder, apple and mesquite just to name a few.

Just make sure you soak them submerged and weighted down in water for at least 2 hours before placing them on your grill, otherwise they will just burn up and you don’t want that.

While your wood is soaking you can be grilling up your veggies. I used yellow squash, zucchini, corn, and red, yellow and orange peppers. They were tossed with a little olive oil, salt and pepper then placed on the grill.

For the mushrooms, the gills and stems were removed, this will give you a nice flat surface for stuffing.

 Brush your mushrooms on the bottom with olive oil and only place them on the grill for 2 to 3 minutes just to get grill marks, caps up. Remove and let them cool completely. If moisture appears just pat with a paper towel.
 Remember, only grill them for a couple of minutes, they will continue to cook on the plank.

I filled my caps with shredded asiago cheese but you could use just about any cheese you want.  Now it’s time to layer your veggies making sure you can see all the different colors. Sprinkle a tiny bit of cheese on top then stick them on the plank!
Try to keep your grill temperature around 350, as their cooking you’ll hear the wood cracking a bit and the sweet smell of the cedar will fill the air.

 The cheese will melt underneath and the veggies will become a little more golden, mine took a good 15 minutes.

Garnish with fresh grilled corn, basil and a drizzle of olive oil.

 The portobellos were infused with a delicate smoky flavor that was so delicious and enhanced all the vegetables.

Trust me, you will love this!

    Made these last Saturday for family guests. They were a BIG HIT WITH EVERYONE !! I did not use the cedar planks, however, (time issue) but did grill everything. I used red, yellow, orange peppers, zucchini, baby eggplant, artichokes and asparagus (no corn). Instead of parm I used Smoked Fontina and fresh herbs. They were amazing leftover, as well. We served them with apricot-Jalapeno glazed smoked Cornish Hens, mashed potatoes and Bacon-Lettuce-Tomato-Hard Boiled Egg (white) Salad with homemade bacon, onion, honey-mustard dressing. Everything was amazing, especially the grilled veggie-filled portabellos !!! Thank you so much, Marie !!! I love, love, love your website! You are amazing!!

    • Babycakes, Thank you so much for your comment, what an absolutely fantastic meal you made, wish I was your guest!

  2. Came upon your blog through pinterest. I love your recipes and the fact that you live close by. My husband and I took a field trip to the Caputo cheese market based on your recommendations. What a great find! I will keep reading your blog to find other great local Chicago treasures. Keep up the great work!

  3. This looks lovely!

    You know, I’ve never doen plank grilling but I’d like to. We have a gas grill and I have to think that the wood gives character that gas grilling lacks.

    Keep writing…

  11. With mouthwatering veggies like this nobody will even miss the meat. What a stunning presentation, Marie. I never would have thought to use a plank for vegetables.
