Wash the asparagus and trim off the tough ends.
Season the asparagus lightly with salt, pepper, grated parmesan cheese, and a sprinkle of garlic powder if desired.
Open the can of crescent roll dough and separate the triangles.
Place an asparagus spear at the wide end of each crescent dough triangle.
Roll the dough around the asparagus, starting from the wide end and wrapping towards the narrow point.
Preheat your air fryer to 375°F (190°C).
Lightly brush each asparagus roll with melted butter or olive oil. This will help them turn golden brown.
Place the asparagus crescent rolls in the air fryer basket in a single layer, ensuring they are not touching.
Air fry for about 8-10 minutes or until they are golden brown and puffed up. Cooking time may vary depending on the air fryer model. In the last minute of cooking, add the grated parmesan cheese and shredded mozzarella cheese over the dough, and cook for another 3-4 minutes or until the cheese has melted.
Remove the asparagus crescent rolls from the air fryer and serve them warm.
