- Peel butternut squash and cut off top and bottom. Slice in half lengthwise and scoop out seeds. Slice into ½-inch slices.
- Beat eggs in a shallow bowl. Add flour to a second bowl. Add panko, smoked paprika, cinnamon and salt to a third bowl and stir to combine.
- Spray the basket of air fryer with cooking spray. Working in two batches, coat each piece of squash lightly in flour, then dip in egg and allow excess to run back into bowl. Coat in panko mixture and place in air fryer. Mist with cooking spray and air fry at 370°F for 7 minutes. Turn butternut squash and air fry for 7 minutes longer. Repeat with second batch of squash.
- While squash cooks, stir together ingredients for maple aioli in a small bowl. Serve squash warm, topped with parsley, and with maple aioli for dipping.
