01 - Preheat oven to 325°F and line a large baking sheet with parchment paper.
02 - Place cashews, almonds, pecans, and walnuts in a large mixing bowl.
03 - Whisk together olive oil and maple syrup in a small bowl until combined.
04 - Pour the oil and syrup mixture over the nuts, tossing thoroughly to ensure even coverage.
05 - Sprinkle Creole seasoning, smoked paprika, cayenne, garlic powder, onion powder, thyme, oregano, salt, and pepper over the nuts. Toss continuously until all nuts are uniformly coated with the spice mixture.
06 - Spread the seasoned nuts in a single layer on the prepared baking sheet, ensuring none are overlapping.
07 - Bake for 18 to 20 minutes, stirring halfway through the cooking time, until nuts become fragrant and golden brown.
08 - Remove from oven and allow nuts to cool completely on the baking sheet. They will crisp up further during the cooling process.
09 - Transfer cooled nuts to an airtight container and store at room temperature for up to 2 weeks.
