Pour the rolled oats into a large mixing bowl. Add the chopped pecans, salt, maple syrup, and vegetable oil.

Stir the mixture thoroughly with a spatula until all ingredients are evenly coated and clump together slightly, forming a sticky, caramel-like consistency.

Spread the mixture evenly onto a parchment-lined baking sheet, pressing down lightly to create an even layer.

Bake in a preheated 350°F (175°C) oven for 20-25 minutes, stirring once at the halfway point, until the granola is golden brown and fragrant.
Remove from oven and let cool completely on the pan; the granola will firm up and form clusters as it cools.
Break into clusters and transfer to an airtight container for storage. Serve as a breakfast cereal or snack.
