Preheat oven to 300°F. Line a large rimmed baking sheet with parchment paper. Whisk honey, oil, lemon extract, salt and cinnamon (if using) together in a large bowl. Add oats, almonds, pepitas and flaxmeal; toss until completely coated. Spread the mixture on the prepared pan and press into an even layer.
Bake, without stirring, for 30 minutes. Sprinkle with coconut and continue baking until golden, about 10 minutes more. Remove from oven. Sprinkle with lemon zest and dried blueberries, pressing them gently into the granola.
Let the granola cool completely, undisturbed, about 30 minutes (the granola will further crisp up as it cools). Break into pieces before serving.
