Preheat the oven to 425 degrees F. Line a large rimmed baking sheet with parchment paper.
Wash and peel potatoes, cut them into chunks or wedges, as evenly in size as possible. Place them in a large bowl.
In a small bowl, whisk together olive oil, salt, pepper, garlic powder, oregano, lemon juice and zest. Pour over potatoes and toss to coat.
Arrange potatoes in a single layer on the lined baking sheet. Roast in the preheated 425 degree oven for 40-50 minutes, tossing once to ensure even cooking.
Once the potatoes are crispy, golden and easily pierced with a fork, remove from the oven and sprinkle with fresh minced parsley. Serve immediately.
