Preheat your oven to 350 F. Lay down some parchment paper on a baking tray.
Pour 1 tablespoon of olive oil over your pumpkin seeds. Give them a little stir to make sure they're all coated. Now, sprinkle in all your spices -- ginger, cinnamon, nutmeg, cloves, cardamom, and a pinch (or more) of cayenne depending on preference.
Drizzle in 2 tablespoons of maple syrup. Give everything a good mix to make sure the seeds are coated.
Spread your seed mix evenly on the baking tray. Pop it into the preheated oven and roast for about 20 minutes. Keep an eye on it to make sure they don't burn. You want them to turn golden and crunchy, not charred.
When they come out of the oven, add the fresh thyme and immediately break up the big chunks of the mix into small pieces.
Add a bit of salt and pepper to taste.
Store your maple roasted pumpkin seed snack mix in an airtight jar in a cool, dark place.
