Don’t throw them out!
The pumpkin innards might be ooky and gooky but it’s worth digging through them for the seeds. And since you are making a family activity of the carving, why not teach the kids about a healthy treat?
We used a cookie sheet with paper towels for the collection of the seeds, just so we had something to wipe them on when our fingers were sticky. Once all of the pumpkins were cleaned out, we rinsed the seeds in a draining basket under hot water and removed all of the remaining pulp.
Try to remove as much water as possible by patting with a paper towel or draining longer. I found the paper towel method to be cumbersome because they stuck to the towel.
Spray a cookie sheet with non-stick spray. I used canola. Then cover the sheet with pumpkin seeds, they may overlap. Then spray a good layer of canola oil on top as well and sprinkle with salt (and pepper, if you choose) or other seasoning like sriracha for hot ones.
Bake on 350 in the oven for 20-25 minutes and cool for 10 minutes.
