In a large bowl mix together the oats and pecans.
In a large measuring cup mix together the brown sugar, honey, pumpkin, cinnamon, & kosher salt.
Pour the pumpkin mixture over the oats and pecans. Stir together until it's all coated.
Line a large sheet tray with parchment and spread the mixture out into a single layer.
Bake at 350 degrees for 30 minutes. Stir every 10 minutes. Watch it closely because the pecans can burn. Be very vigilant around the 24 minute mark.
When it's finished sprinkle about 2 tsp. of large flake sea salt over top and leave it sit on the tray to cool for 1 hour. The granola will feel kinda soft when you bring it out of the oven. It will get crunchy and break off into large chunks once it cools.
Store in a plastic bag or container for up to 1 week.
