Prepare the Dredging Station
In one bowl, mix the flour with a pinch of black pepper.
In a second bowl, whisk the eggs with the milk.
In a third bowl, combine the panko, Parmesan (if using), Italian seasoning, fleur de sel, and smoked paprika.
Coat the Mushrooms
Pat the mushrooms dry. Dip each one into the flour, then the egg mixture, then press into the seasoned panko until fully coated.
For extra crunch: repeat the egg + panko step for a double coating.
Fry Until Crispy
Heat about 1 inch of oil in a deep skillet to 350°F (180°C).
Fry the mushrooms in small batches for 2–3 minutes per side, or until golden and crisp.
Transfer to a paper towel–lined plate.
Serve Hot
Sprinkle with a pinch of flaky salt and a little extra Italian seasoning if desired.
Serve with your favorite dip and lemon wedges.
