Ingredients
Just a few basic ingredients used to make a simple seasoning sprinkled on fresh mushrooms, and you can have a quick vegetarian air fryer side dish ready to go.
- Portobello mushrooms: the large mushrooms you see at the market! These are a bit meatier in texture because of how big they are, and they have a little earthy flavor, so they’re a perfect substitute for a vegetarian main course or to use as a hearty side dish.
- Onion powder and garlic powder: these are my go-to combo for a simple spice mixture, they give a perfect little kick of flavor.
- Salt and pepper: need to season! Kosher salt and fresh cracked black pepper are always preferred.
- Oil: I found an oil spray to be easiest for these mushrooms to make sure all the surface area is getting covered. I used avocado oil spray but you can use a different oil such as olive oil.
- Parsley: a nice fresh element that pairs deliciously with the earthy mushrooms.
Step by step instructions
The best part about cooking in the air fryer is how easy it is and these air fryer mushrooms are no different.
1. Clean the mushrooms. Using a barely damp paper towel, gently brush it along the surface of the mushroom to remove any dirt and debris.
2. Season the mushrooms. Give the front and back a good spray with avocado oil. Then sprinkle over the spice mixture of garlic powder, onion powder, kosher salt, and black pepper evenly over both sides of the mushrooms.
3. Air fry. Preheat your air fryer to 375F. Add the seasoned mushrooms to your air fryer basket in a single layer. Cook them for about 10 minutes, flipping half-way through. Cook time may vary based on the thickness of the mushrooms.
4. Finish with parsley. Slice the cooked mushrooms into strips and sprinkle with fresh chopped parsley.
Tips and tricks
- Easily clean mushrooms by rubbing a damp towel over their top to remove any dirt and debris.
- Air fry in a single layer – this will help make sure the mushrooms cook through and get tender on the inside and crispy edges.
- Mix up the seasonings – add or swap in cayenne, cumin, Italian seasoning, or chipotle powder.
- Use different fresh herbs – thyme, rosemary, cilantro, would all be great.
- To test if your mushrooms are done, if you poke them with a fork or knife in the center if they are juicy and tender they’re done.
- If you don't have olive oil spray, you can use regular olive oil and then use a basting brush to make sure it gets all over the surface.
How to serve
Another one of the great things about this recipe is it can be served in so many different ways:
- They have a great meaty texture so they're a good vegetarian swap as the “meat” in a portobello burger or as a portobello “steak”
- This is a great side dish that goes well with so many others: mashed potatoes, green beans, brussels sprouts, broccoli.
- Serve alongside some mains: braised beef, roasted chicken, roasted fish, in a vegetarian grain bowl.
Storage
Let the mushrooms cool to room temperature then store them in an airtight container in the fridge for up to 3 days. They’ll lose a bit of their texture and may get a bit wrinkly but are still fine to consume within 3 days.
To reheat, warm in the air fryer or oven at 350F for a few minutes. You could also easily warm them in the microwave but you’ll get no crisp back that way.
FAQs
No, the gills of a portobello mushroom are completely edible and fine to keep in. But if you’d like to take them out you can.
Same as gills, it’s largely preference to keep or remove the stem of the mushroom! If the stem is long I’d recommend at least trimming it, but I personally removed them entirely.
Sure can! Bake the mushrooms on a parchment paper lined baking sheet at 425 for 15-20 minutes.
Sure! Cremini mushrooms (aka baby bella) or button mushrooms would be great. They're all smaller so you don't have to cook as long, roughly ½ the time.
No, not really - just cook the mushrooms in a single layer regardless of the size of your air fryer basket, that's the most important part. I use the Ninja Foodi 5-in-1.
