Preheat the air fryer: Set to 390°F (200°C) for 3–5 minutes. A hot basket helps the chips crisp fast.
Slice the hot dogs: Cut into thin coins, about 1/8 to 1/4 inch thick. Thinner slices get crispier.
Try to keep them similar in size for even cooking.
Season: In a bowl, toss hot dog slices with oil, smoked paprika, garlic powder, onion powder, pepper, and any optional spices. Make sure every piece is lightly coated.
Prepare the basket: Lightly spray the air fryer basket with cooking spray to prevent sticking.
Arrange in a single layer: Place slices in one even layer. Do not overcrowd. Work in batches if needed for the best crunch.
Air fry: Cook for 6–9 minutes, shaking the basket halfway.
Start checking at 6 minutes. They’re done when edges are deeply browned and crisp.
Rest briefly: Let chips cool 1–2 minutes in the basket. They’ll firm up a bit more as they rest.
Serve: Transfer to a plate and pair with your favorite dips.
Sprinkle with a pinch of extra paprika or a little flaky salt if you like.
