In a large mixing bowl whisk together the lemon juice, olive oil, chicken stock, garlic powder and 1 tablespoon of the oregano.
Add the potatoes to the bowl and toss to combine.
Spread the potatoes in an even single layer on a large rimmed baking sheet or shallow baking dish. Season with salt and pepper.
Roast the potatoes until tender and the stock is absorbed, about 35 minutes. Flip the potatoes and continue to cook until they are golden brown with crispy edges for an additional 20 to 25 minutes. If desired, broil on high until golden brown, about 2 minutes.
