  • Larger portobello mushrooms: To make portobello fries you need large portobello mushrooms.

Portobello mushrooms are a more proteinaceous variety of the quintessential Champignons mushroom: their scientific name is Agaricus bisporus and they are considered the largest domestic mushrooms, with a very large cap that can reach up to 15 cm in diameter.

  • All purpose flour & water: We will need them to create the batter that keeps the breadcrumbs attached to the mushrooms.
  • Spices: You can use whatever spices you like for the preparation of this recipe.

I used salt, black pepper, garlic powder and Italian seasoning.

  • Plain bread crumbs or panko bread crumbs: The ingredient that will make this air fryer portobello mushrooms super crispy.

How To Cook – Step Instructions

  • Clean mushrooms: Cleaning Portobello mushrooms is really simple, the only caution is to treat them gently because they tend to darken easily.

First remove the stem with the help of a knife.

Using a spoon, gently remove the dark gills from the underside of the mushroom.

Remove soil residue from the rest of the mushroom by cleaning it thoroughly and gently with a damp cloth or a piece of kitchen paper moistened with water; be careful not to put the mushrooms under running water.

  • Cut mushrooms: With a well-sharpened knife, gently slice the mushroom.

Taking care to make and slice all the same thickness, to get a more even cooking.

  • Remove excess water from mushrooms: To ensure a super crispy result, I recommend removing excess water from mushrooms.

Cover the cut mushrooms with a napkin and cover them with a baking tray.

  • Prep The Breading Station: In a bowl, pour the flour and cold water and mix with a whisk until the batter is smooth.

In another bowl put the breadcrumbs with the spices and mix.

  • Preheat air fryer: This is done to ensure a more even cooking.
  • Bread the mushrooms: Using kitchen tongs, pass the mushroom slices first in the batter and then in the breadcrumbs, making sure to cover the entire surface of the mushrooms.
  • Cook the mushrooms: Place the breaded mushrooms in the air fryer basket, in a single layer.

Spray a little olive oil on top and cook for about 5 minutes.

Turn them over and let them cook for another 5 minutes.

Tips For The Best Results

  • Do not wash mushrooms under running water: wipe with a wet cloth.
  • Before breading them, remove the excess water: for a unique crispness I recommend removing the excess water from the mushrooms. Place a dry cloth over the mushrooms you have already cut, and press them with a baking sheet.
  • Preheat the air fryer: I always say, it is a good thing to preheat the air fryer, this serves for more even cooking of the food.
  • Use a cooking spray for the oil.

How To Serve

These air fryer mushrooms make a perfect side dish that all mushroom lovers will love, but they are also make a great appetizer.

I love to accompany them with these crispy chicken cutlets, breaded pork chops or this baked chicken kabobs in the oven.

If you want to make them for an appetizer instead serve them along with these homemade coktails.

You will amaze your guests!

This air fryer portobello fries are a great addition to a portobello burger, air fryer chicken burgers or this vegan pizza.

Favorite Dipping Sauce

You can serve them with the sauce you like best; it’s a personal preference. 

I love to serve them with pink sauce. To make it just mix in a small bowl mayonnaise with Worcestershire sauce, a little ketchup sauce, brandy and tabasco if you want to make it spicy.

How To Store Leftovers:

Store: For best results, store mushrooms in the refrigerator in an airtight container. For up to 2 days.

Freeze: My advice is to freeze them breaded and uncooked.

Place them in a baking dish, being careful and not to let them stick.

Let them harden in the freezer for a couple of hours and then you can transfer them to a freezer bag.

Cook them then when frozen, just extend the cooking time by a couple of minutes.

Reheat: To reheat them you can do it directly in air fryer for 3/4 minute at 375 F.


How do I make my portobello not soggy?

Do not wash them under running water and instead clean them well with a damp paper towel. Remove the “gills,” the lower part of the cap of portobello mushroom caps, to reduce extra liquid during cooking.

Should I remove gills from portobello mushroom?

The portobello mushroom gills are edible, but for the success of this recipe I recommend you remove them.

Why mushroom should not be washed?

Washing the mushroom in water is strongly discouraged because, as it behaves like a sponge, it tends to fill with water.
