To cut and peel the kohlrabi, remove the top and bottom of the bulb with a sharp, butchers knife. Make sure to remove more from the bottom and check to make sure that all is left is the soft, white flesh. If the bottom looks fiberous, cut more away, the bottom has a denser flash towards the roots that is not pleasant to eat.
Using a pairing knife, remove the outer skin from the kohlrabi, cutting away in long ribbons until all of the peel is gone.
Slice the kohlrabi with butchers knife into uniform sticks, about 1/2 inch by length kohlrabi bulb you are working with.
When all of the kohlrabi is sliced place into large bowl and cover with olive oil. Mix to cover kohlrabi thoroughly.
Sprinkle Garam Masala and salt over olive oil coated kohlrabi, taking time to mix and turn the fries as needed to ensure even covering of spices.
Place in a single layer on bottom of air fryer basket and set air fryer at 300 degrees for 20 minutes. Shake air fryer basket occasionally while checking for doneness.
The fries should be sizzling with toasted spices and crisp on the outside, you may need to adjust cooking time depending on the air fryer you are using.
