Pat the 1.5 lbs (680g) of chicken breast dry with a paper towel. Transfer the cubed chicken to a large mixing bowl. Pour over the 2 tbsp (30ml) of olive oil, tossing until every piece is slick and coated. Sprinkle in the garlic powder, onion powder, kosher salt, and black pepper. Toss vigorously until the spices form an even, tacky layer on the meat.

Thread 4 to 5 seasoned chicken cubes onto each skewer. Place the assembled skewers into the air fryer basket in a single layer, leaving a small gap between each skewer to guarantee maximum airflow.

Set your air fryer to 400°F (200°C) and cook for 10-12 minutes. Halfway through the cooking time, open the basket and carefully flip each skewer until a deep golden-brown crust forms and the internal temperature reaches 165°F (74°C).

While the chicken is cooking, melt the unsalted butter in a microwave-safe bowl. Stir in the minced garlic cloves, coarse grated Parmesan cheese, and half of the finely chopped fresh parsley.

Remove the hot skewers from the air fryer. Immediately brush the skewers generously with the garlic parmesan butter. Finish by sprinkling the remaining coarse grated Parmesan cheese and finely chopped fresh parsley over the top.
