Trim the tough ends off the bottom of the asparagus.
In bundles of 5 or so spears, wrap the bacon around the asparagus as tight as possible.
Place the bundles in the air fryer basket with the loose ends of the bacon down.
Cook in the air fryer for 10 minutes. You do not need to flip the asparagus at the halfway point. If the bacon comes apart, quickly wrap it back around while it’s still warm.
Remove the asparagus bundles to a platter. Allow the bundles to cool slightly before eating.
