(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
Directions
Preheat the Oven:
- Preheat your oven to 425°F (225°C). Place a wire rack on a baking sheet and lightly coat it with cooking spray to ensure even crispiness.
Prepare the Mushrooms:
- Remove the stems from the Portobello mushrooms and use a spoon to scrape out the gills. Discard the gills.
- Slice the mushrooms into thin strips, about ¼-inch thick, to resemble fries.
Set Up the Coating Station:
- In one bowl, place the flour and season with a pinch of salt and pepper.
- In a second bowl, beat the eggs.
- In a third bowl, combine the Panko breadcrumbs, Parmesan cheese, and Italian seasoning.
Coat the Mushroom Slices:
- Dip each mushroom strip into the flour, ensuring it’s evenly coated.
- Next, dip the floured mushroom strip into the beaten eggs, letting any excess egg drip off.
- Finally, press the mushroom strip into the breadcrumb mixture, coating it thoroughly.
Bake the Fries:
- Arrange the coated mushroom slices on the prepared wire rack. Bake in the preheated oven for 10-14 minutes, or until the fries are golden brown and crispy. Keep an eye on them to prevent burning.
Make the Aioli:
- In a small bowl, combine the mayonnaise, lemon juice, lemon zest (if using), minced garlic, black pepper, and a pinch of sea salt. Mix well. Refrigerate until ready to serve.
Serve:
- Remove the mushroom fries from the oven and serve immediately with the aioli or your favorite dipping sauce.

FAQs
1. Can I use other types of mushrooms?
Yes, you can use other mushrooms like white button mushrooms or cremini mushrooms, but Portobello mushrooms work best for the “fries” texture due to their larger size.
2. Can I make these fries ahead of time?
You can prep the mushroom slices and bread them ahead of time, then store them in the fridge for a few hours before baking them.
3. Can I make the aioli ahead of time?
Yes, the aioli can be made ahead of time and stored in the fridge for up to 2 days. This allows the flavors to develop.
4. Can I fry these instead of baking them?
Yes, you can fry the mushroom fries in oil for a crispier texture, but baking them is a healthier option.
5. How do I keep the fries crispy?
Using a wire rack allows air circulation, which helps the fries stay crispy while baking. If you don’t have a wire rack, you can bake the fries directly on the baking sheet, but turning them halfway through will help achieve an even crisp.
6. Can I freeze the mushroom fries?
Yes, you can freeze the breaded mushroom fries. Place them in a single layer on a baking sheet and freeze until solid. Transfer to a freezer bag and store for up to 3 months. To cook, bake from frozen at 425°F for about 15-20 minutes.
7. Can I add other seasonings to the breadcrumb mix?
Absolutely! Feel free to experiment with different herbs or spices like thyme, rosemary, or garlic powder for extra flavor.
8. Can I make these without Parmesan?
Yes, you can skip the Parmesan or replace it with a vegan cheese option for a dairy-free version.
9. How can I make the aioli spicier?
For a spicier aioli, add a pinch of cayenne pepper or a splash of hot sauce to the mixture.
10. Can I serve these fries with other sauces?
Yes, you can serve them with a variety of sauces, such as ranch dressing, marinara sauce, or even a tangy barbecue sauce for a unique twist.
