Soak wooden skewers in water for at least 30 minutes.
Combine spice mixture in a small bowl and set aside.
Prep your chicken by cutting into 3" pieces. Place them in a bowl and toss in olive oil and the spices, coating well on all sides.
Pack the chicken onto each skewer, making sure they are tightly packed with no space in between.
Make the garlic parmesan sauce by combining all ingredients in a saucepan over low heat. Scoop out ⅓ of the sauce and use that for basting the chicken as it cooks. Reserve the remaining sauce for basting the cooked chicken.
Cook 2-3 skewers at a time in an air fryer at 400 degrees for 5 minutes. Remove and flip the skewers and baste with sauce, returning to cook an additional 2 minutes at 400 degrees. Baste with more sauce and cook another 5-6 minutes or until the internal temp reaches 165 degrees. Once they are finished cooking, baste them with the reserved sauce and sprinkle with parmesan.
Enjoy!
