In a mixing bowl, combine the popcorn kernels with avocado oil. Toss well to ensure all the kernels are evenly coated.
Preheat your air fryer to 400°F (200°C).
Once preheated, carefully place the coated popcorn kernels in the air fryer basket. Spread them out evenly.
Cook the popcorn in the air fryer for about 8–10 minutes, listening for the popping sounds to slow down.
Carefully remove the basket from the air fryer and pour the popcorn into a large mixing bowl. Drizzle melted butter and sprinkle with salt and other seasonings, then toss well.
