Start by draining and patting the pickles dry with paper towels. This step is necessary to help the breading stick.
Cut whole dill pickles into spears or thick slices, depending on your preference.
Prepare your workstation: Season the flour with half of the salt and pepper in a shallow dish. In a separate bowl, whisk the eggs with mustard, then season them with the remaining salt, pepper, paprika, and chili flakes. Place this bowl next to the flour dish. In another shallow dish, set the breadcrumbs and position them beside the egg mixture.
Coat each pickle spear first in flour, then dip it into the egg mixture, and finally roll it in the breadcrumb mix. Ensure an even coating for the best results.
Set your air fryer to 383℉ - 195℃.
Lightly oil the pickle fries using a brush or spray them with cooking spray.
Arrange the breaded pickle fries in a single layer, leaving space between each piece for proper air circulation.
Air fry for 8-10 minutes, flipping halfway through for even crisping.
Check for a golden-brown crust. If needed, air fry for an additional 1-2 minutes.
Remove the pickle fries from the air fryer and let them cool slightly. Serve with your favorite dipping sauce, such as ranch or spicy aioli.
