Preheat oven to 400°F. Lightly oil a baking sheet or coat with nonstick spray.

Place potatoes in a single layer on the sheet. Add olive oil, basil, oregano, thyme, garlic, and parmesan, and season with salt and pepper. Gently toss to combine.

Place in oven 25-30 mins, until golden brown and crisp. Stir in butter until melted, about 1 minute.
