Preheat the air fryer: Set it to 350°F (175°C) for 3–5 minutes. A hot basket helps the dough puff and crisp.
Prep the dough: Unroll the crescent dough and separate it into 8 triangles. If you’re adding cheese or mustard, have it ready.
Dry the hot dogs: Pat them with a paper towel. Dry hot dogs help the dough stick and brown evenly.
Add fillings: Place one strip of cheese at the wide end of each dough triangle.
If using mustard, brush a light stripe over the cheese or directly on the hot dog.
Wrap: Set a hot dog on the wide end and roll it up toward the tip, keeping the dough snug but not stretched thin. Tuck the ends slightly if they’re loose.
Optional egg wash: Brush the tops with beaten egg for a glossy finish. Sprinkle with seasoning if you like.
Air fry, first side: Lightly mist the basket with oil.
Arrange the wrapped hot dogs seam-side down in a single layer, leaving space between them. Cook at 350°F (175°C) for 5 minutes.
Air fry, finish: Check for color. If the tops are pale, cook another 2–4 minutes until deep golden and crisp.
Total time is usually 7–9 minutes.
Rest: Let them sit 2 minutes. This helps the cheese settle and keeps the dough flaky.
Serve: Pair with ketchup, mustard, barbecue sauce, or a quick honey-mustard dip.
