01 - Preheat oven to 425°F. Line a large baking sheet with parchment paper.
02 - In a large bowl, whisk together olive oil, garlic, lemon zest, lemon juice, oregano, salt, and pepper until well blended.
03 - Add the potatoes to the bowl and toss thoroughly to coat evenly with the marinade mixture.
04 - Spread the potatoes in a single layer on the prepared baking sheet, avoiding overcrowding.
05 - Roast for 30 to 35 minutes, turning once halfway through cooking, until golden brown and crisp on the edges with fork-tender interiors.
06 - Remove from the oven and transfer to a serving platter. Sprinkle with fresh parsley if desired. Serve immediately while hot.
