01 - Preheat oven to 425°F. Line a large baking sheet with parchment paper.
02 - In a large bowl, whisk together olive oil, minced garlic, lemon zest, lemon juice, dried oregano, salt, and freshly ground black pepper until well combined.
03 - Add quartered potatoes to the marinade bowl and toss thoroughly to coat evenly with all seasonings.
04 - Spread coated potatoes in a single layer on the prepared baking sheet, avoiding overcrowding for optimal crispiness.
05 - Roast for 30 to 35 minutes, turning potatoes once halfway through cooking, until golden and crispy on the edges with fork-tender interiors.
06 - Remove from oven and transfer to a serving platter. Garnish with fresh parsley if desired and serve immediately while hot.
