Preheat your air fryer to 390°F (200°C).
Place the hot dogs in the air fryer basket without overcrowding.
Cook the hot dogs for 5 minutes, shaking halfway through for even cooking.
Check for doneness; they should be crispy and heated through.
If using cheese, add it on top of the hot dogs for the last 2 minutes of cooking.
Remove the hot dogs and place them in the buns.
Add desired toppings like bacon bits and jalapeños.
Serve with chili sauce, mustard, and ketchup.
Enjoy your delicious air fryer hot dogs!
