You can get grill-quality hot dogs in a snap!
Warm the air fryer up to 390 F.
First, let's toast those buns. Place the buns in fryer's basket and cook for 2 minutes. Move the buns over to a serving plate.
Now for the dogs themselves. Place the franks in the fryer's basket and let them cook for 3 minutes. Carefully remove the franks from the fryer and place them in the buns. Top 'em off with your favorite fixings (which better include mustard if you want to do this right).
