First, preheat your oven to 400°F (200°C). While it heats up, thoroughly wash and scrub your potatoes to remove any dirt. Pat them completely dry with a towel, as this helps them get crispy. Then, cut the potatoes into even, bite-sized halves or quarters.
In a large bowl, combine the olive oil, minced garlic, chopped rosemary, thyme, salt, and pepper. Add the cut potatoes to the bowl and toss everything together until each piece is evenly coated with the fragrant oil and herb mixture.
Spread the seasoned potatoes in a single, even layer on a baking sheet lined with parchment paper. Don't overcrowd the pan. Roast for 35-40 minutes, flipping them halfway through, until they are golden brown, crispy, and easily pierced with a fork.
Once they are perfectly roasted, remove the potatoes from the oven and let them cool for a minute. If you're using parsley, sprinkle the freshly chopped leaves over the hot potatoes. This adds a final burst of freshness and a beautiful touch of green.
