Preheat oven to 300 degrees. Line a baking sheet with parchment paper or aluminum foil. Set aside.
Combine oats, pecan halves, brown sugar, cinnamon and salt together in a large bowl. In another bowl, combine the melted butter, maple syrup, vanilla extract and egg white. Drizzle over the oat mixture and toss until completely combined.
Dump onto the prepared baking sheet and spread out evenly. I like to press it down some to create bigger clusters in the granola. If you don't care for the clusters, spread it out loosely. Bake for 30 minutes, or until golden brown.
If you like a less clumpy granola, stir it right after removing from the oven then let cool completely on the pan. If you want the clusters, let it cool completely on the pan then break it into pieces. Store in an airtight container.
