Preheat air fryer: Set your air fryer to 400°F (200°C) and let it preheat for 3–5 minutes.
Season chicken: In a large bowl, toss chicken pieces with olive oil, garlic powder, paprika, salt, and pepper until evenly coated.
Air fry: Arrange chicken bites in a single layer in the air fryer basket. Cook for 8–10 minutes, shaking halfway through, until golden and cooked through (internal temp 165°F).
Make garlic butter: While chicken cooks, melt butter in a small saucepan over low heat. Add minced garlic and cook for about 1 minute until fragrant (don’t burn).
Combine: Transfer cooked chicken to a bowl, pour the garlic butter over the top, and toss until evenly coated.
Garnish and serve: Sprinkle with parsley and a squeeze of lemon juice if you like. Serve hot with rice, pasta, or a simple veggie side.
