Remove Hotdogs from package and use a knife to make 5 shallow diagonal cut marks in each hotdog. This will give the hotdog room to expand while cooking plus it looks great! Make sure to not cut too deep, you really only want to slice the skin of the hotdog.
Preheat your airfryer (or don’t). I have done this with or without preheating and they both come out great.
Add 6 hotdogs to the air fryer basket. I have a large Air Fryer so this fits easily. If you do not have a spacious air fryer, cook the hotdogs in two batches. Cook for 6 minutes at 390F
Remove the hotdogs from the airfryer, put them in a bun, and place the bun with the hotdog back in the airfryer. This will ensure the bread gets nice and toasty! Don’t skip this step. Cook for an additional 2 minutes at 390F. Also, make sure there is space between each bun. This allows the bun to get nicely toasted all around.
Remove from air fryer, add toppings, and enjoy!
