Preheat your oven to 180°C (350°F) and line a baking sheet with parchment paper.
Measure out about 3 cups of mixed nuts and place them in a large mixing bowl, checking for any broken pieces or shells.
In a small bowl, whisk together smoked paprika, cayenne pepper, cinnamon, and salt to create your spice blend.
In a separate bowl, combine the olive oil and maple syrup, then pour the mixture over the nuts.
Use a spatula to toss the nuts until they are evenly coated with the oil and syrup.
Sprinkle the spice blend over the coated nuts and toss again to distribute the spices evenly.
Spread the nuts in a single layer on the prepared baking sheet for even roasting.
Bake in the preheated oven for 15-20 minutes, shaking the pan every 5 minutes to ensure even roasting and prevent burning.
Once fragrant and golden brown, remove the nuts from the oven and allow them to cool completely on the baking sheet, where they will crisp up as they cool.
Transfer the cooled nuts to an airtight container or jar. Serve at room temperature for maximum crunch and flavor.
