Clean the outside of the pumpkin you will be using before removing the top and scraping out the insides, aka pumpkin guts.
Use your fingers to remove as much of the pumpkin guts as you can and place them in a measuring cup. You'll need about cups of seeds.
Toss the seeds in the bottom of a pot. No need to clean the seeds first. You just need most of the pumpkin goo off them.
Pour 4 cups of water over the seeds.
Add ½ Tbs salt and stir the contents of the pot together.
Place the pot on the stovetop over medium-high heat.
Bring to a boil and boil the pumpkin seeds in salt water for 10 minutes.
Preheat the oven to 300 degrees.
Line a cookie sheet with aluminum boil or parchment paper.
Drain the seeds and place them in a small bowl.
Melt the butter carefully in the microwave.
Whisk in the ½ teaspoon salt, garlic salt, and Worcestershire sauce.
Pour the butter mixture over the pumpkin seeds and stir to coat all the seeds.
Dump the pumpkin seeds onto the prepared baking sheet and spread them out into a single layer.
Bake at 300 for 45-60 minutes.
The pumpkin seeds should be golden brown and crunchy!
This delicious snack can be served warm or cooled!
Store cooled roasted seeds in an airtight container.
