Bring 3 cups of water and 1 cup of farro to a boil in a medium saucepan.
Reduce heat, cover, and simmer for about 25–30 minutes until farro is tender but still chewy.
Drain any excess water and let it cool completely. (Tip: You can cook the farro ahead of time and refrigerate it.)
Preheat your oven to 325°F (165°C) and line a large baking sheet with parchment paper.
In a large mixing bowl, combine the cooked and cooled farro, oats, coconut flakes (if using), chopped nuts, seeds, and salt.
In a small saucepan over low heat, warm the maple syrup (or honey) and coconut oil until just melted.
Remove from heat and stir in the vanilla extract.
Pour the wet mixture over the dry ingredients and mix thoroughly until everything is evenly coated.
Spread the granola mixture evenly on the prepared baking sheet.
Bake for 35–40 minutes, stirring halfway through to ensure even browning.
Watch closely toward the end, as granola can burn quickly.
Once golden brown and fragrant, remove the granola from the oven and let it cool completely.
Stir in dried fruit after cooling to prevent it from getting hard or burned.
