My Cajun mushrooms are just as scrumptious hot and fresh off the stove as they are straight-out-the-fridge-cold, y'all. Raw quartered mushrooms, boiled til fork-tender while the Cajun trinity veggies and garlic brown down in the pan. Then, all mixed together with south Louisiana-inspired pantry items that create a fun, feisty flavor profile that goes with just about anything savory that you happen to have on hand. Yep and yay...

Ingredient Essentials

Ingredients for Cajun mushrooms in bowls and ramekins against a white backdrop.
  • Fresh mushrooms are the most important ingredient in this recipe, y'all. Since you'll be using the stem, choose mushrooms that are the same shape and size to ensure the optimal beauty of the finished dish comes through.
  • Cajun trinity veggies and garlic lend loads of flavor and texture to this recipe. 
  • Any kind of olive oil works in this recipe. Likewise, any brand of balsamic vinegar can be used, as long as it is pleasing to your palate. 
  • Roasted red peppers add their own sassiness to the prepared mushrooms. 
  • Louisiana pantry items, such as Zatarain's Creole mustard and Crystal hot sauce give the Cajun mushrooms their authentic flavor profile. 

How to Make Cajun Mushrooms 

To start, clean the mushrooms. Then, turn them upside down so that the stem is facing up. Cut the mushroom in half, then in half again. Repeat until all of the mushrooms are quartered. 

Next, chop the Cajun trinity veggies, parsley, and garlic. Then, gather the remaining ingredients. 

Now, bring a small pot of water to a boil. Then, boil the mushroom quarters for about 3 to 5 minutes, or until fork-tender.

While the mushrooms are boiling, place the raw chopped onion, bell pepper, and celery in a skillet along with the olive oil.

And, cook until browned, about 10 minutes. Add the garlic during the last minute of brown time.

Finally, transfer the Cajun mushrooms to a glass bowl immediately. This stops the cooking process, which helps the mushrooms stay juicy throughout the cooling-down time and up to three days covered in the refrigerator.

And that's it, y'all!!

These Cajun mushrooms are honestly one of my first original recipes. And, I had loads of fun creating their feisty flavor and unforgettable textures. I think you'll feel the same way, too, if you're a mushroom lover like I am. 

Perfectly seasoned with a few surprising tongue twists, this appetizer or side dish just gets better and better once cooled and refrigerated. So, you have numerous chances to jazz up whatever you're serving throughout each batch.

Storage

Store tightly covered in the fridge for up to 3 days. But, do not freeze as the mushrooms will just turn mushy and unpalatable.
