Step 1
Preheat oven to 300º F. Line a baking sheet with parchment.
Step 2
In a medium saucepan or microwaveable bowl, combine all ingredients together except the pumpkin seeds and heat, stirring occasionally, just until sugar dissolves and butter melts.
Step 3
Add the pumpkin seeds and toss until well coated.
Step 4
Spread pumpkin seeds with any excess coating out in a single layer on the sheet pan and roast 25-30 minutes, turning and tossing mixture once or twice while roasting. Continue to roast until the seeds are dry and golden brown.
Step 5
Serve seeds warm or store up to 1 week in a covered container. Seeds may be reheated in the oven at 200°F for 10 minutes before serving. For best results, do not microwave to re-heat.
Grease tongs when tossing the seeds to keep the coating from sticking to the tongs.
