Preheat the oven to 400°F. Place the potatoes on a large baking sheet. Drizzle with 3 tablespoons olive oil and sprinkle with 1½ teaspoons salt and ½ teaspoon pepper. Toss with your hands to coat the potatoes well. Roast for 30 minutes.
Remove from the oven and stir. Then, roast another 15 minutes until the potatoes are lightly browned and crisp. Remove from the oven, and transfer the potatoes to a medium size bowl.
Dressing Instructions
Whisk together the remaining 2 tablespoons of olive oil, vinegar, and garlic in a small measuring cup or bowl. Pour over the potatoes and stir well to coat. Sprinkle with the remaining ½ teaspoon salt and ½ teaspoon pepper. Top with chives and parsley and toss well.
Notes
I like to buy the tiniest potatoes I can find for this recipe and simply slice them in half. However, any potato will work, just cut the potatoes into 1-inch pieces.
