Preheat the oven to 325 degrees F. Line a baking sheet with parchment paper.
In a medium mixing bowl, whisk together the sweetpotato puree, honey, olive oil, and egg white.
In another large mixing bowl, combine the oats, pecans, cinnamon, pumpkin spice, and salt.
Add the wet ingredients to the dry ingredients and stir until everything is well combined and coated.
Pour the mixture onto the parchment-lined baking sheet, spreading evenly. Bake at 325 degrees for 25-35 minutes total on the center rack, stirring at the 15-minute mark. Keep a close eye on the granola towards the end of the cooking time as you don’t want it to burn (if it starts to get too dark around the edges, pull it from the oven).
Let cool on the pan for at least 30 minutes; it will crisp up as it cools. Enjoy!
