Wild Rice Stuffed Portobellos that are easy to make, gluten-free and vegan and full of nutrition for a delicious weeknight side dish recipe. Perfect for mushroom and non-mushroom lovers alike!

Food will forever remind me of certain places and experiences. Not surprisingly, my idea of being a tourist in a city is eating my way across it. What better way to immerse yourself into a new culture than to eat like a local?

Bratwurst in Berlin, Poke in Maui, Falafel in Jerusalem, I’ve eaten my way across a lot of cities. Wild rice will always remind me of Minnesota. I didn’t realize the northern state is “famous” for wild rice until I went to the Minneapolis Farmers Market a few years ago and got the full run down from a wild rice harvester. 

He convinced me and I left with a bag of wild rice. It sat in my cupboard, untouched for a while. I don’t know why I was intimidated by it! You cook it just like any other rice… by following the instructions on the package. I decided to make wild rice stuffed portobellos and they’re so tasty.

Wild Rice Stuffed Portobello Ingredients

  • portobello mushrooms
  • wild rice
  • yellow onion
  • garlic
  • olive oil
  • chopped almonds
  • balsamic vinegar
  • dried thyme (or fresh thyme, if preferred)
  • sea salt and ground pepper
  • optional: fresh thyme for garnish

Buying and Preparing Portobello Mushrooms

When buying portobello mushrooms, look for firm mushrooms that are uniform in color – not spotty. They should not be slimy but more of a dry, tacky texture. If you buy them in a package at the store, keep them in the package in your refrigerator until you’re ready to use them. The packages are designed to keep mushrooms fresh! If you buy loose mushrooms, store them in a brown paper bag in your fridge.

Give them a good wash before using to remove any dirt or grime. Then remove the stems from the caps. Slice off the very bottom of the stems but reserve the rest as we’ll use them in our stuffed mushroom mix!

How to Make Stuffed Portobellos

STEP 1: Remove stems from portobellos and chop finely. Set portobellos and chopped stems aside, separately.

STEP 2: Cook ½ cup of wild rice according to package directions. Let cool in a large bowl.

STEP 3: Place a large pan over medium-high heat and add the almonds. Cook until toasted – watching carefully and stirring occasionally to make sure they don’t burn! Place in bowl with wild rice when toasted.

STEP 4: Add olive oil to the large pan and add the onion and garlic. Cook on medium heat for 2-3 minutes or until the onion has softened slightly and garlic is fragrant. Add in the chopped portobello stems and cook for an additional 2 minutes. 

STEP 5: Add in the onions, garlic and stems to the wild rice and almond mixture. Add in the balsamic vinegar, thyme, salt and pepper. Stir to combine. 

STEP 6: Line portobello caps along a baking sheet and drizzle with olive oil. Top each portobello with ⅓ cup of wild rice mixture. Bake at 350ºF for 15 minutes. Top with fresh basil if desired and enjoy!

Storing and Reheating Stuffed Mushrooms

Let the mushrooms cool completely before storing in an airtight container. Store leftovers in your refrigerator for up to five days. When you’re ready to enjoy, I recommend reheating in a conventional oven or toaster oven but you can use a microwave if you’re in a hurry!

  1. Poutine at 4 am…I like your style. My favorite way to experience a new city/culture is definitely through the food. Escargot in France, paella in Spain (although, don’t buy paella from a Chinese man in Spain— authenticity down the drain), peaches in Georgia… New York is known for being a melting pot of many cultures, but people tend to like our cheesecake. 🙂
    I ♥ wild rice, so I might just join in on your family dinner.

  2. Who knew Minnesota was known for wild rice? I definitely didn’t! I love the taste and texture of wild rice though. These look delicious and I’m sure his parents will love them!

    I explore new places through their food too. I don’t care what hotels we stay at, what clothes I pack, or whether I have room for a hair dryer… but you can be sure I have researched the heck out of the restaurant scene ahead of time and planned out everywhere I want to go. 😉

  3. Yummy yummy in my tummy!! Sounds really delicious.
    The city where I study (Mainz, Germany) is known for Brezel with Obatzter which is a cheesy, creamy dip. However I think it’s traditionally a Bavarian dish. But who wants to be picky!
    I’m on holiday in LA right now and will also be doing trips to Las Vegas and San Francisco. I’m so going to eat some local food!! Can’t wait for a lobster roll. It’s not even traditional for these city I think but it is American and I’m at the coast so that counts! 🙂

  4. So fun! I love stuffed portobellos. I can’t say that I’m sure what San Diego is known for (perhaps fish tacos or super fresh produce in general?!) but my home state of NJ is definitely known for its sweet tomatoes and probably all things Italian. Living in Cali, I miss being able to get amazing fresh mozzarella (although I’m in Jersey now and ate TONS of mozzarella last weekend so now I’m all good!)!

  5. I’m all about trying recommended vegan restaurants when I travel. I love trying new plantbased meals. I live by a small city in Central New York so there isn’t a ton of options. Oh and vegan bakeries are very important to find! 🙂
