Preheat your oven to 180°C (350°F) and line a baking sheet with parchment paper or a silicone mat to prevent sticking.
Place the mixed nuts into a large mixing bowl, making sure they are raw and unsalted for the best flavor and crunch.
In a small bowl, whisk together the oil, honey or maple syrup, cinnamon, smoked paprika, cayenne pepper, and a pinch of salt until well combined.
Pour the spice mixture over the nuts and toss with a spatula or your hands until each nut is evenly coated with the fragrant glaze.
Spread the coated nuts in a single layer on your prepared baking sheet, shaking off excess to prevent clumping.
Bake for 15-20 minutes, stirring once halfway through, until the nuts are golden, fragrant, and slightly darker around the edges.
Remove the nuts from the oven and sprinkle with flaky sea salt while still warm to enhance flavor and add a satisfying crunch.
Let the nuts cool completely on the baking sheet, allowing them to crisp up further as they cool.
Once cooled, transfer the spiced nuts to an airtight container. Store at room temperature for up to two weeks for maximum crunch and aroma.
Enjoy these crunchy, aromatic nuts on their own, or toss them into salads, cheese boards, or snack mixes for extra flavor and texture.
