Preheat the air fryer to 300°F (150°C) for about 5 minutes.

Rinse the raw pumpkin seeds under cold water to remove any pulp.

Pat the seeds dry using a clean kitchen towel or paper towels.

In a mixing bowl, combine the seeds with olive oil, salt, garlic powder, and smoked paprika.

Spread the seasoned seeds in a single layer in the air fryer basket.

Cook for about 12-15 minutes, shaking the basket halfway through.

Check for a golden-brown color and a crunchy texture after 12 minutes.

Once done, remove the seeds from the air fryer and let them cool completely.
