Step 1: Prepare the Chicken

1. Soak Wooden Skewers: If you’re using wooden skewers, start by soaking them in water for at least 30 minutes to prevent burning.
2. Season the Chicken: Combine paprika, garlic powder, onion powder, salt, and pepper in a small bowl. Cut the chicken into 3-inch pieces, then place in a large bowl or zip-top bag. Add the olive oil and seasoning mixture, ensuring each piece is well-coated.
3. Skewer the Chicken: Thread the chicken pieces onto the skewers tightly, leaving no gaps between them. This helps keep the chicken juicy. If necessary, snip the ends of the skewers to fit them in your air fryer.

Step 2: Make the Garlic Parmesan Butter Sauce

1. Melt the Butter and Garlic: In a microwave-safe bowl, combine the butter and minced garlic. Heat until the butter is partially melted, then whisk together.
2. Add the Remaining Ingredients: Stir in the red pepper flakes, hot sauce, parsley, and Parmesan. Whisk until combined. If the sauce starts to separate, add 1-2 tbsp of softened butter to re-emulsify it.
3. Separate the Sauce for Basting: Set aside one-third of the sauce for basting the raw chicken during cooking. Reserve the remaining two-thirds to baste the cooked chicken.

Step 3: Cook the Chicken

Air Fryer Method

1. Cook in Batches: Preheat the air fryer to 400°F. Place 2-3 skewers in at a time to avoid overcrowding.
2. Initial Cook: Cook the skewers for 5 minutes, then remove and flip them.
3. First Baste: Baste with the reserved sauce, then cook for another 2 minutes at 400°F.
4. Final Cook: Flip again, baste with sauce, and cook for another 5-6 minutes or until the internal temperature reaches 165°F.
5. Final Baste and Serve: Once done, give a final brush with the reserved sauce and sprinkle with extra Parmesan before serving.

Oven Method

1. Preheat and Prepare: Preheat your oven to 450°F and line a baking sheet with foil.
2. Bake the Skewers: Place the skewers on the baking sheet and bake for 14 minutes, flipping halfway and basting with butter a few times.
3. Broil for Crispy Edges: Switch to broil and cook for an additional 2 minutes for a golden finish.
4. Final Baste and Serve: Remove from the oven, give a final baste with the sauce, and sprinkle with Parmesan before serving.

Grill Method

1. Preheat Grill: Heat the grill to medium-high.
2. Cook and Baste: Place skewers over direct heat, cooking for 5-6 minutes on each side, basting throughout.
3. Final Baste and Serve: Remove from the grill, baste one last time, and sprinkle with Parmesan before serving.
