Thoroughly rinse the pumpkin seeds in water, until all the pumpkin strands have been removed.
Spread on a teatowel and let dry.
Line a cookie sheet with tinfoil and preheat the oven to 350°F.
Place the seeds in a bowl and drizzle with olive oil to lightly coat.
Sprinkle with your seasonings of choice (I like salt, some garlic powder, Mrs. Dash, salt, and some of my all purpose rub)
Spread on the cookie sheet and bake for 15 minutes, then give the seeds a toss to turn over.
Bake for another 15 minutes, then let cool.
Notes
If you'd like to air fry them, layout in one layer, set the temperature for 350°F, air fry 10 minutes, toss to turn over, and do another 3-8, depending on how done you want them.
