Carve your pumpkin and separate the seeds from the guts and place them in a medium bowl.
Clean the pumpkin seeds by placing in a colander and running cold water over, remove all pieces of guts. Spread the seeds onto a baking sheet lined with paper towel or cotton towel and allow to dry for at least 20 minutes. Transfer the seeds back into the medium bowl and drizzle with olive oil.
In a small bowl combine salt, pepper, garlic powder, seasoned salt and cayenne pepper and mix.
Sprinkle the seasoning over the pumpkin seeds a little at a time, stirring in between sprinklings.
Spread the pumpkin seeds onto a baking sheet lined with parchment paper or baking mat. Bake at 300 degrees for 25 - 30 minutes, stirring every 5-10 minutes. Bake until seeds are golden brown and the middle is crunchy. Try the pumpkin seeds to make sure the middle is cooked, it should be crunchy and not soft.
