Preheat the air fryer: Set it to 390°F (200°C) for 3–5 minutes. A hot basket helps get that crisp skin.
Prep the hot dogs: Make 3–4 shallow diagonal slashes on each hot dog or prick lightly with a fork.
This prevents bursting and helps the heat get inside.
Optional oil: Lightly rub or spray the hot dogs with oil for extra blistering. It’s not required, but it does boost texture.
Air fry: Arrange hot dogs in a single layer. Cook for 5–7 minutes, shaking once halfway.
For extra char, add 1–2 more minutes.
Toast the buns: Open the buns and place them in the basket cut-side up. Air fry at 350°F (175°C) for 1–2 minutes until lightly toasted.
Set up the toppings bar: While the hot dogs cook, arrange toppings in small bowls with spoons and tongs. Keep cold items chilled and warm items (like chili) heated.
Assemble and serve: Add hot dogs to toasted buns and let everyone build their own.
Serve immediately for the best snap and warmth.
