In a large bowl, add the asparagus and drizzle with avocado oil, sprinkle with garlic salt and black pepper, and mix together until asparagus is evenly coated.
Place the asparagus in a single layer on the tray of your air fryer and cook at 400 degrees F for 7 minutes.
Notes
To ensure a crisp texture, avoid stalks that are wilted or limp. Instead, choose ones that are rich green with compact tips.
