Preheat oven to 275°F. Line a large baking sheet with parchment paper.

Combine chili powder, cumin, coriander, paprika, brown sugar and garlic powder in a small bowl. Toss pecans and Worcestershire sauce in a large bowl. Sprinkle the spice mixture over the pecans, tossing to coat. Spread the spiced nuts on the prepared baking sheet.

Bake the pecans, tossing every 8 to 10 minutes, until lightly browned and very fragrant, about 35 minutes. Transfer to a bowl; sprinkle with salt and toss well. Let cool.

Tip: Refrigerate chili pecans in an airtight container for up to 1 month.
