Stir the nuts in a medium bowl.
Add the oil, maple syrup, rosemary, thyme, brown sugar, chipotle pepper, 1/2 teaspoon kosher salt, cinnamon, cumin, and cayenne pepper to the nut and stir well to combine until the nuts are evenly coated.
Spread on a parchment-lined quarter sheet pan and place in the oven. Roast for about 15-25 minutes, stirring occasionally. Keep a close eye on the nuts at the 15 minute mark, as they can quickly get too dark.

Break apart any clumps and transfer to clean glass jars for storage. Enjoy!
