Separate pumpkin seeds from pulp, then transfer seeds to a baking sheet. Let dry for at least 30 minutes.
Drizzle seeds with olive oil and sprinkle with salt. Mix well.
Roast seeds, stirring every five minutes, until they're toasted and crispy (about 20 to 25 minutes).
While seeds bake, combine pumpkin pie spice and sugar in a medium bowl.
When seeds are finished cooking, transfer to bowl with sugar-spice mixture. Mix well. Add additional salt to taste, if desired.
Let seeds cool, then store any leftovers in an airtight container until ready to eat. Enjoy!
Notes
A large pie / sugar pumpkin will yield about one cup seeds, but you'll get a lot more from a jack-o'-lantern type pumpkin. Depending on how many seeds you have, you can size the recipe up (or down).For best results, spread the seeds in a single layer on your baking sheet before roasting. Use two sheet pans instead of one, if you have lots of seeds so they're not crowded.Make sure to stir the seeds every five minutes as they bake. This helps them cook evenly, so every seed get crunchy throughout.If you'd like to make your own Pumpkin Spice mixture, stir together the following spices:
1 ½ teaspoons ground cinnamon
1 teaspoon ground ginger
¼ teaspoon ground cloves
¼ teaspoon ground nutmeg
