Heat the oven to 325 degrees and position the rack in the middle. In a small saucepan, combine the vegetable oil, garlic and pepper. Set over medium-low heat and cook until the garlic browns slightly, about 10 minutes. Remove from the heat.
Strain the mixture through a fine-mesh strainer into a small bowl.
Place the chips in a large bowl. Use a brush to “paint” the oil onto the chips. (Store the leftover oil in a sealed container and use it for salad dressings or on potatoes destined for roasting.) Spread the chips onto a rimmed baking sheet. Bake the chips until hot and aromatic, about 10 minutes. Sprinkle with fresh pepper and scoop into a serving bowl or basket.
