Start by preheating your oven to 430 degrees Fahrenheit so it's nice and hot by the time your potatoes are ready. In a large bowl, combine the melted butter, minced garlic, salt, black pepper, and herbs. Stir everything together so the garlic and herbs are evenly distributed through the butter.
Add your halved potatoes directly into the bowl with the butter mixture. Toss everything together until every piece is fully coated, making sure the garlic and herbs cling to the cut sides. This step is what gives you that flavorful crust once they roast.
Spread the coated potatoes out on a baking sheet in a single layer, cut side down if you can manage it. Giving them enough space is key here since overcrowding will cause them to steam instead of crisp up. A little breathing room makes all the difference in texture.
Slide the pan into your preheated oven and roast for 30 to 40 minutes. You'll know they're ready when the edges turn deep golden brown and a fork slides easily through the center. Keep an eye on them during the last ten minutes since ovens vary.
Once out of the oven, toss the potatoes with fresh chopped parsley while they're still hot. This little step brightens up the whole dish and adds a pop of color. Serve them right away while the edges are still crispy.
