If you are looking for a vegetarian classic, you have to try air fryer portobello mushrooms.
They come out slightly crispy on the outside and tender on the inside, and even made our very own mushroom critic (Eric) like mushrooms!
You can make these portobello mushrooms in just a few minutes with a simple seasoning blend and then serve them as a side dish or a veggie burger option, slice them onto salads or sandwiches, and lots more.
Ingredient Notes
- Portobello mushrooms – Try to use mushrooms of roughly similar size. They shouldn’t have dark spots or feel slimy/spongy.
- Oil – We like to use avocado oil, but you can use your preferred oil.
- Balsamic vinegar – Optional, but we recommend adding it if you have any on hand.
- Italian seasoning – For some more flavor. Fine herb seasoning or your favorite seasoning mix also works (just be sure to omit the salt if the seasoning mix contains salt already).
- Salt – Enhances the overall flavor. Adjust the amount to taste. We use regular table salt.
- Garlic Powder – For extra flavor; Alternatively, you can also use minced fresh garlic (use a knife), but keep in mind that it may not stick well to the mushrooms, and there’s a risk of it getting too dark
- Black Pepper – Adds a hint of spice. We like to use freshly cracked pepper.
Recipe Tips
- Clean the mushrooms gently with a damp (paper) towel before seasoning them. We don’t recommend rinsing them under running water.
- Feel free to change up the seasoning blend to suit your taste. Cajun seasoning, cayenne pepper, or chili flakes all work well if you want to add a little more heat.
- Don’t overcrowd the air fryer. The mushrooms should fit in the air fryer basket in one layer without overlap.
- Your air fryer, the thickness of the mushrooms, and your desired level of tenderness will affect the total cooking time. You can always check if they are done by piercing them with a fork.

Step-by-Step Instructions
First, clean the portobello mushrooms with a damp (paper) towel. Then place the portobello mushrooms onto a large plate or into a baking dish.
Add the oil, balsamic vinegar, Italian seasoning, salt, garlic powder, and black pepper to a small bowl and mix well.
Brush both sides of the mushrooms with the seasoning mixture.
Preheat the air fryer to 380 degrees Fahrenheit (about 195 degrees Celsius). Once it’s hot, add the mushrooms to the air fryer with the cap side down. They should fit without overlap. Otherwise, cook in batches.
You can spoon any of the leftover seasoning mixture onto them at this point.
Cook the mushrooms for 6-7 minutes for medium-sized mushrooms, and 8-10 minutes for large portobello mushrooms, flipping them halfway through the cooking time.
Flip them over halfway through the cooking time. Since every air fryer is slightly different, your exact cooking time can vary.
When the portobello mushrooms are cooked to your liking, remove them from the air fryer.
Serve them with dips of your choice, as a side dish, or use them for a portobello burger or as the base for eggs Benedict (thanks to Lynn for suggesting this in the comments).
Storage Tips
You can store leftover portobello mushrooms in a sealed container in the fridge for up to 3-4 days. The mushrooms generally have a lot of moisture in them, so don’t be surprised if they get slightly soggy in the fridge.
To reheat them, we recommend the air fryer again since it will help dry out some of the excess moisture. The microwave will also work – but don’t expect them to be crispy.

- In a small bowl, mix together 1 tablespoon oil, ½ teaspoon balsamic vinegar, ½ teaspoon Italian seasoning, ¼ teaspoon salt, ¼ teaspoon garlic powder, and ¼ teaspoon black pepper.

Flip them over halfway through the cooking time. Since every air fryer cooks slightly differently, your exact cooking time can vary.

Absolutely delicious Added paka’s mild curry just a small amount for flavor for an Indian taste. Pepper and mixed Bo salt spices 8 minutes at 400degrees . Oh so good
That sounds delicious – thanks for sharing, Connie!
Followed the recipe pretty closely. Only change I would make is to halve the salt.
I’m going to try these soon, I plan on having them as the base to my eggs Benedict! So I won’t be using as many spices.
As base to eggs Benedict sounds SOO good! Ty.
