Start by preparing your buns. Open each hot dog bun gently so it doesn’t tear completely. Place one slice of cheese on each inner side of the bun. This will create that classic melty cheese barrier that hugs the hot dog. Then, insert the cooked hot dog in the center and gently press the bun closed.

Now, butter the outside of each bun generously. This step is important because the butter helps the exterior crisp up beautifully in the air fryer. You can also mix in garlic powder or herbs into the butter for a little flavor twist.

Preheat your air fryer to 375°F (190°C) for a couple of minutes. Then, place the assembled hot dogs in the air fryer basket. Be sure not to overcrowd them—work in batches if needed.

Air fry for 5 to 7 minutes, flipping halfway through, until the bread is golden brown and crispy and the cheese is perfectly melted. When done, use tongs to carefully remove them and let them cool for a minute before serving.

These grilled cheese twist hot dogs are best enjoyed warm when the cheese is still gooey and the crust is nice and crisp.
