Air fry the Dogs Preheat your air fryer to 375 °F . Arrange hot dogs in the basket and cook 6-7 minutes, turning halfway, until heated through and lightly blistered.
Prep the Buns Split buns without cutting all the way through. Spread about 1 tablespoon pizza sauce inside each bun to coat the bottom.
Assemble the Pizza Dogs Place a cooked hot dog in each sauced bun. Top with another spoonful of pizza sauce, a generous sprinkle of mozzarella, and 3 pepperoni slices on top of each one.
Melt & Toast Carefully return the loaded hot dogs to the basket and cook an additional 2–3 minutes, just until cheese is melted and buns are lightly toasted.
Finish & Serve Remove with tongs, garnish with Parmesan, basil, or red-pepper flakes if desired, and serve immediately with extra pizza sauce for dipping.
