Preheat the oven to 400 degrees F. Line a baking sheet with parchment paper.
Place the baguette slices on the prepared baking sheet. Mix the oil, parsley and garlic together in a bowl. Brush the garlic oil on both sides of the baguette. Bake until golden brown and crispy, 15 to 20 minutes.
This oil/parsley/garlic mixture also works well for garlic bread or on a grilled cheese sandwich.
