Preheat the oven to 400°F (200°C) and prepare a large baking sheet by lining it with parchment paper.

Using a pastry brush, generously coat both sides of each baguette slice with olive oil. Evenly sprinkle the slices with kosher salt and a dusting of garlic powder on both sides to ensure full coverage.

Arrange the seasoned slices in a single layer on the prepared baking sheet, ensuring they do not overlap.

Bake in the preheated oven for 5 to 7 minutes, or until the undersides turn a rich golden brown. Carefully flip each slice over and continue baking for an additional 5 to 7 minutes, watching closely to avoid over-browning.

Allow the toasted baguette slices to cool completely on a wire rack. Once cooled, they are ready to be served alongside dips, or topped with your favorite spreads and garnishes.
