If you're not using pre-chopped nuts, place them in a food processor and pulse 3-4 times until they’re chopped. Alternatively, chop the nuts with a knife on a cutting board.
Combine all the dry ingredients and nuts in a large mixing bowl.
Add the oil and maple syrup and stir to evenly coat the oat mixture.
Spread the oat mixture evenly on 2 parchment lined half-sheet pans.
Place in the sheet pans oven and bake for 1 hour and 15 minutes. Feel free to give the granola a stir once or twice during the baking. Though I never stir it and it turns out great.
Remove from the oven and allow to cool. If you want to add dried fruit, now’s the time. I don't add dried fruit because everyone in my house prefers the granola without.
Store at room temperature in an airtight container.
