Preheat the oven to 400ºF. Line a baking sheet with parchment paper. Set aside.
Place the pecans, maple syrup, and cinnamon in a large bowl and mix well. Make sure the nuts are fully coated.
Spread the nuts in an even layer on the prepared baking sheet. Sprinkle with sea salt.
Bake for 7-10 minutes or until the nuts begin to caramelize.
Let cool for at least 10 minutes before removing the pecans from the pan. Enjoy immediately or transfer to an airtight container.
