Rinse the asparagus and pat dry. Trim the woody ends by gently bending each spear near the bottom until it snaps.
Season the asparagus with garlic powder, black pepper, and salt.
Wrap each asparagus spear with a slice of bacon, starting from the bottom and spiraling up to just below the tip.
Place the bacon-wrapped asparagus in the air fryer basket in a single layer, ensuring they do not overlap for even cooking.
Cook for 10-12 minutes, or until the bacon is crispy and asparagus is tender. You may need to adjust the time based on the thickness of the bacon and asparagus.
