Heat the oven to 300°F / 150 C / Gas mark 2. Place the oats, brown sugar, cinnamon, and salt in a large bowl and stir to combine and set aside.
Place the honey, oil, and vanilla into a jug and mix thoroughly. Pour over the oat mixture and mix until the oats are thoroughly coated.
Spread the mixture in a thin, even layer on a rimmed baking tray lined with greaseproof paper.
Bake for fifteen minutes, then stir, breaking up any large clusters and continue baking until the granola is a very light golden brown, for between five and ten more minutes.
