Preheat your air fryer to 375°F (190°C).
In a mixing bowl, toss the sliced Kielbasa with olive oil, garlic powder, paprika, salt, and pepper.
Place the seasoned Kielbasa slices in the air fryer basket in a single layer.
Air fry for 8-10 minutes, shaking the basket halfway through for even cooking.
Serve hot with your favorite dipping sauce or as a main dish.
