Pat the asparagus dry and snap off the end of the spears or trim them with a knife and cutting board.
Mix together the dark brown sugar and garlic and herb seasoning until combined in a small mixing bowl.
Lay the bacon out on a piece of parchment paper and sprinkle the spice mixture all over the bacon. You won’t need it all, some will be left for the outside.
Wrap the asparagus up in the spiced bacon, 2 stalks per piece of bacon.
Sprinkle more of the seasoning mix on the outside of the asparagus bunches.
Place only 4-5 bunches of bacon wrapped asparagus in an even layer in the preheated air fryer and cook for 6-8 minutes or until the edges of the bacon are crispy and the asparagus is cooked through, turning halfway through.
Remove from the air fryer and place on a plate covered with a clean paper towel. Serve warm.
