Slice off the ends of the squash and then cut it into 2 ½-3 inch rounds. Slice those in half, then in half again to create wedges.
In one dish combine the Wondra flour with salt and pepper. In another dish whisk together the egg, milk and hot sauce. In the third dish, combine the grated Parmesan cheese and Panko bread crumbs.
Dip the squash wedges in the flour, then the egg mixture and finally into the Parmesan-panko mixture, shaking to remove excess after each. Repeat with all squash wedges.
Set the air fryer to Air Fry at 375 degrees for 10 minutes. Add the squash fries in an even layer into the basket (or on the rack) and cook. If your air fryer has a "turn food" option, use tongs to gently move them around, or gently shake them in the basket.
While they're cooking, make up the dipping sauce by combining ranch dressing and hot sauce until fully combined.
Notes
Parmesan Squash Fries can be served with a spicy ranch dipping sauce, warmed up marinara sauce or a pesto. I cooked these in an Instant Vortex 6 quart air fryer. Temperatures and cook times may vary depending on the brand of air fryer you have.
