Prep. I prefer using the air fryer recipe for roasting because it's much more practical than using the oven. Typically, I like to preheat my air-fryer.
Dry the seeds. To begin roasting pumpkin seeds, ensure they're completely dry and the pumpkin pulp removed. Place the dried seeds into a medium bowl.
Add seasonings. Combine melted butter (or olive oil) with garlic & onion powder, salt, and black pepper, ensuring an even coating over all the seeds. Spread seasoned pumpkin seeds in a single layer onto the air fryer basket.
Air fry. Air fry pumpkin seeds at 350°F for around 15-20 minutes until golden brown, remembering to shake the basket halfway through for uniform roasting. Afterward, check their crispiness, and if needed, air fry them for an extra 3-5 minutes for the desired texture.
Allow to cool and enjoy. Once done, allow them to cool down. Adjust the seasoning to your liking and indulge in this delicious snack.
