Rinse the pumpkin seeds thoroughly to remove any pumpkin pulp. Pat dry with a paper towel.
Let the seeds air dry for about 30 minutes for extra crispiness.
In a bowl, toss the seeds with olive oil and salt. Add your favorite seasonings if desired.
Preheat the air fryer to 360°F (182°C).
Place the seasoned pumpkin seeds in a single layer in the air fryer basket.
Air fry for 10–15 minutes, shaking the basket every 5 minutes to ensure even cooking.
Once golden and crisp, remove and let cool before serving.
