Cut into the top of the pumpkin around the stem and remove the top. Use a slotted spoon to remove all of the pulp from the inside of the pumpkin, including the seeds.

Place in a large bowl. You will likely be able to separate the pumpkin pulp from the seeds fairly easily.
Add the pumpkin seeds to a colander and rinse with cold water. This will help shake loose any of the other pumpkin pieces from the seeds.

Bring about 3 cups of fresh water to boiling, add 2 teaspoons salt. Add the pumpkin seeds and boil 5-10 minutes. This step helps to completely clean the seeds and helps add flavor to the seeds.

Next, drain the seeds and place in between two clean dish towels. Dry well and add to a clean bowl.

Add the oil and spices, toss and roast at 350 degrees F for 15-25 minutes. The cooking time will vary depending on how big, how dry or how roasted you like your seeds. Watch closely and remove when the seeds are golden brown and fragrant.
