Drain pumpkin: Place a double layer of paper towels on a large plate. Spread ½ cup canned pumpkin puree evenly over the paper towels. Place another layer of paper towels on top, gently pressing to absorb excess moisture. Let it sit for about 10 - 15 minutes, then carefully remove the top layer of paper towels and transfer the drained puree to a medium bowl for use.
Mix dry ingredients: Meanwhile, in a large bowl, combine 3 cups old-fashioned rolled oats, ½ cup pepitas, ½ cup pecans, ¾ cup golden flax seeds, ¼ cup chia seeds, ¼ cup sesame seeds, 1 tablespoon pumpkin pie spice, 1 teaspoon ground cinnamon, 1 teaspoon ground ginger, and 2 teaspoons sea salt.
Mix wet ingredients: To the medium bowl, add the ⅓ cup light brown sugar, ¼ cup maple syrup, 2 tablespoons extra-virgin olive oil, and 2 teaspoons vanilla extract, and whisk until smooth.
Combine the wet ingredients into the dry until the oats are well-coated.
Spread: Evenly spread the mixture on a full sheet pan (or two half-sheet pans). Sprinkle with 1 tablespoon demerara or turbinado sugar if using, and flaky salt.
Bake: Bake for about 30 - 35 minutes, stirring halfway through, until the mixture is deeply golden brown, the oats are mostly dry to the touch, and the kitchen smells wonderful.Note: Because the pumpkin puree stains the oats, it'll already be "golden brown" before baking, so it can be more difficult to tell when they're done. I recommend saving a piece of raw granola to compare to the cooked version. Once it's darkened significantly, it's ready!
Cool: Place the baking sheet on a wire rack to cool. After a few minutes of cooling, sprinkle 1 cup dried cranberries on top, then cool completely, about 1 hour. Store in an airtight container, and enjoy!
