01 - Preheat oven to 325°F and line a baking sheet with parchment paper.
02 - In a large bowl, combine olive oil, melted butter, smoked paprika, cayenne pepper, garlic powder, onion powder, thyme, oregano, salt, black pepper, and brown sugar. Stir until thoroughly blended.
03 - Add mixed nuts to the bowl and toss vigorously until evenly coated with the spice mixture.
04 - Spread nuts in a single layer across the prepared baking sheet.
05 - Bake for 18-20 minutes, stirring once halfway through, until nuts are golden and fragrant.
06 - Remove from oven and let cool completely on the baking sheet. Nuts will achieve maximum crunchiness as they cool.
07 - Transfer to an airtight container and store at room temperature for up to one week.
