How to Make Air Fryer Portobello Mushroom Fries with Step-By-Step Instructions
A complete printable recipe and the measurements in both US customary and metric are available in the recipe card below.
Prepare the Mushrooms
Slice the portobello mushrooms into 2-inch long sticks, ensuring they are thick enough to hold up when dipped and cooked.
Prepare the Coating
Crack an egg into a bowl and beat lightly. In a separate bowl, mix together the flour, panko breadcrumbs, Parmesan cheese, garlic powder, onion powder, and a pinch of salt and pepper.
Coating the Mushrooms
Dip each mushroom stick first into the beaten egg, allowing excess to drip off, and then coat thoroughly in the breadcrumb mixture. This dual-dipping ensures each fry is fully coated and extra crispy.
Air Frying
Spray the air fryer basket with cooking oil spray to prevent sticking. Arrange the coated mushrooms in a single layer in the basket; you may need to work in batches depending on the size of your air fryer.

Cook the mushroom fries at 320°F (160ºC) for about 15 minutes, or until golden brown and crispy. Shake the basket halfway through cooking to ensure even crisping.
Serve the hot mushroom fries garnished with freshly chopped parsley. They pair wonderfully with your favorite dipping sauces like marinara, ranch, or a spicy aioli.

Notes
- Choosing Your Mushrooms: Opt for portobellos that feel heavy for their size and have a firm, smooth cap. These are fresher and will hold up better during the cooking process.
- Consistent Cut: Aim for uniform slices when cutting your mushrooms into fries. This ensures they all cook at the same rate and finish at the same time.
- Dry Ingredients Tweak: Feel free to play with the dry mix. Adding a bit of smoked paprika or chili powder can offer a nice kick if you like your snacks with a bit of heat.
- Egg Alternative: If you’re vegan or allergic to eggs, a slurry of cornstarch and water makes an excellent binding agent for the breadcrumbs.
- Avoid Overcrowding: Give your mushroom fries plenty of space in the air fryer. This isn’t just about preventing them from sticking together; it’s about allowing the air to circulate freely so each one gets evenly crispy.
- Shake or Turn: Halfway through, either shake the basket or turn the fries with tongs. This simple step is key to achieving an even crispness on all sides.
- Check for Doneness: Start checking on your fries a few minutes before the timer goes off. All air fryers are a bit different, and the perfect crisp might come sooner than you think.

How to Store Air Fryer Portobello Mushroom Fries
Storing leftover Air Fryer Portobello Mushroom Fries is straightforward and ensures you can enjoy their crispy texture even the next day. Here’s how to keep them in top condition:
Cool Down Completely: Before storing, let your mushroom fries cool completely on a wire rack. This helps to prevent steam from building up, which can make them soggy.
Use Paper Towels: Line an airtight container with paper towels. Place the fries in a single layer and cover them with another paper towel. This setup absorbs any excess moisture and keeps the fries crisper.
Refrigerate Properly: Seal the container and store your fries in the refrigerator. They will stay fresh for up to three days.
Reheat to Perfection: When you’re ready to eat the leftovers, reheat them in the air fryer at 360°F for about 3-4 minutes or until they’re heated through and crispy again. This method revives the fries much better than a microwave can.
