Preheat the oven to 275 degrees F. Line a rimmed baking sheet with parchment paper.
Spread granola on the prepared baking sheet and bake at 275 degrees F for 50-60 minutes, until golden brown. Stir the granola every 15 minutes.
Store leftover granola in an airtight container. It should stay fresh for about 5-6 days.
If you can't have coconut, you can leave it out and just use more oats instead.
