Recipe Tips
Before you make portobello mushroom in the air fryer, read through these recipe tips so that you achieve the best results!
- Make sure to gently clean the mushrooms with a damp towel before adding any oil or spices. We don’t recommend cleaning them unde (running) water unless they are very dirty since they soak up the water (which can change their flavor slightly).
- You can change up the spices to suit your tastes. We went light on the hot spice but you can definitely add Cajun rub or cayenne pepper to the spice blend.
- Your air fryer, the thickness of the mushrooms and your desired level of tenderness will dictate the total cooking time. You can always check on the fleshy inside with a fork as they cook.

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, salt, Italian seasoning, black pepper, and garlic powder to a small bowl and mix well.
Brush both sides of the mushrooms with the spice dressing.
If your portobello mushrooms are very big, you might want to add some extra salt, pepper, or garlic powder to ensure good spice coverage.
Preheat the air fryer to 380 degrees Fahrenheit. Once it’s hot, add the mushrooms to the air fryer with the cap side down.
You can spoon any of the leftover dressing into them at this point.
Make sure that the portobello mushrooms fit into the air fryer in one layer without overlap. If you can’t fit them in all at once, cook them in two batches.
Cook the mushrooms for 6-7 minutes for medium-sized mushrooms, and 8-10 minutes for large portobello mushrooms.
Flip them over halfway through the cooking time. Since every air fryer is slightly different, your cook time can vary.
When the portobello mushrooms are cooked to your liking, remove them from the air fryer and serve with dips of your choice, as a side dish or use them for a portobello burger.
Storage Tips
You can store leftovers of your air-fried portobello mushrooms in a sealed container in the fridge.
The mushrooms generally have a lot of moisture in them so don’t be surprised if they get moist/soft in the fridge. They’ll last like this for around 3 days but eat them sooner rather than later.
To reheat them, we’d recommend the air fryer again since it will help to dry out some of the excess moisture in the mushrooms. Otherwise, the microwave will work – but don’t expect them to be crispy again!

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.
