01 - Preheat the oven to 350°F and line a baking sheet with parchment paper.
02 - Place the cashews, almonds, and pumpkin seeds in a large mixing bowl.
03 - In a small bowl, whisk together olive oil, maple syrup, rosemary, thyme, oregano, lemon zest, sea salt, black pepper, and smoked paprika until well combined.
04 - Pour the herb-oil mixture over the nuts and seeds, tossing thoroughly to ensure even coating.
05 - Spread the coated mixture in a single layer on the prepared baking sheet.
06 - Bake for 13 to 15 minutes, stirring once halfway through, until the nuts and seeds are golden and emit a fragrant aroma.
07 - Allow the mixture to cool fully on the baking sheet; it will crisp up as it cools.
08 - Transfer to an airtight container and store for up to one week.
