Clean parsnips. Then carefully cut them into about 3 mm chips with either a sharp knife or a mandolin.
Place raw chips in bowl. Add oil, salt, and spices. Mix to spread seasoning evenly.
Place parsnip chips in air fryer (*see NOTES below). They will overlap (pending your style of air fryer), and that is okay! You will shake the basket throughout to move around.
Air fry parsnip chips at 375 degrees for 14-17 minutes. Be sure to stop the fryer every 3-4 minutes to shake the basket and mix the parsnips to ensure even cooking. NOTE: If using a toaster oven air fryer that allows for less overlap of chips, cook time may be less. Flip the chips at about the 4 minute mark, and be sure to check for doneness every 3-4 minutes.
As you check for doneness, remove chips that are darker/done, allowing more space for remaining chips.
Once out of air fryer, parsnip chips will continue to get a bit crispier if they are spread out on a flat surface and not overlapping for another 1-2 minutes.
Enjoy these crispy, chewy parnsips while still warm. Serve alone or with dip of choice.
Notes
*Crispness: For the most crispy parsnip chips, cook one layer at a time. This will take more time to cook multiple batches with a basket style air fryer, but each batch will take less time (likely 7-10 minutes per batch, flipping at the 4 minute mark).Personally, I enjoy the balance of crispy and chewy (and being done in less time!) so I just throw them all in at once and shake the basket throughout as written in the recipe.Leftovers: Store leftover in refrigerator. To reheat, throw in air fryer for 2-3 minutes. I do not recommend freezing leftovers.
