Ingredients

  • 5-6 portobello mushrooms
  • 3/4 cup all-purpose flour 90 grams
  • 3/4 cup ice-cold water 180 grams
  • 1/2 tsp salt adjust to taste
  • 1/4 tsp black pepper adjust to taste
  • 2 cups panko breadcrumbs
  • oil spray

Sriracha Mayo Sauce (optional, more options in post above)

  • 1/4 cup kewpie mayo
  • 1 Tbsp Sriracha
  • 1/2 Tbsp rice vinegar
  • salt to taste

Instructions

  • Give the mushrooms a quick rinse and wipe clean. Remove the stems. Scrap the black gills on the bottom side of the mushroom with a spoon.
  • Cut the mushroom into roughly 1/2" thick slices.
  • Add the panko breadcrumbs to a bowl.
  • Mix the flour, salt, black pepper, and ice water together in a separate bowl until smooth. The consistency should be just thick enough so that it can stick onto a mushroom slice.
  • Use a fork to dip the mushroom slices in the flour and water batter. Let the excess batter drip off the mushroom.
  • Dip the coated mushrooms into the panko. Use your hands to pack the panko onto the mushrooms well and shake off the excess panko. Set aside.
  • If making the sriracha mayo sauce: mix all ingredients in a bowl. Taste and adjust seasonings as needed.

Baking (Oven)

  • Preheat your oven to 425F. Optional: Place a sheet of parchment paper over a sheet pan.
  • Place the breaded mushrooms on the sheet pan, evenly spacing them apart. Spray both sides of the fries with cooking spray.
  • Bake for up to 15-20 minutes or until they're golden brown and crispy, flipping over halfway through baking.
  • Serve alone or with your favorite dipping sauce.

Baking (Air Fryer)

  • Preheat the air fryer to 425 F.
  • Place the mushrooms into the air fryer basket. Spray both sides of the fries with cooking spray.
  • Bake them for 8-10 minutes or until they're golden brown and crispy, turning them halfway through.
  • Serve alone or with your favorite dipping sauce.

Frying

  • Pour at least 2 inches of vegetable oil into a deep pan/pot. Heat the oil to 350F.
  • Fry the mushroom fries in batches. Fry for 3-4 minutes, or until golden brown and crispy.
  • Place the fries on paper towels to remove excess oil. Optionally serve with a dipping sauce.
