Preheat oven to 325° and line a baking sheet with parchment paper

Combine butter, sugar and salt in a medium saucepan. Melt butter over medium-low heat, stirring occasionally. Bring to a boil and boil for one minute stirring constantly.

Remove from heat and stir in oats. Pour mixture onto prepared baking sheet and spread out with a spatula

Place in oven and cook for 10 minutes. Stir oats, then continue to bake for an additional 7-9 minutes or until golden brown. Watch closely towards end of cooking time so they don't burn.

Remove from oven and allow to cool on baking sheet. Once cooled, store in an airtight container.
