Preheat your air fryer to 400°F (200°C) for 3-5 minutes.
Place the hot dogs in the air fryer basket, making sure they're not touching each other for even cooking.
Cook for 3 minutes until the hot dogs develop a slight char and begin to curl at the edges.
Open the air fryer and add the buns to the basket, placing the hot dogs inside them.
Continue cooking for 2 more minutes until the buns are nicely toasted.
Carefully remove the hot dogs and buns from the air fryer using tongs.
Add your favorite toppings and serve immediately.
