Preheat your air fryer to 400°F (200°C).
Place the hot dogs in the air fryer basket in a single layer.
Cook the hot dogs for 6-8 minutes, turning halfway through.
Check for desired crispiness; add an extra minute if needed.
While hot dogs cook, prepare your toppings and buns.
Lightly toast the buns in the air fryer for the last 2-3 minutes if desired.
Remove the hot dogs from the air fryer carefully.
Assemble the hot dogs in the buns.
Top with mustard, ketchup, relish, and any other toppings you like.
Serve immediately and enjoy!
