Place the potatoes in a large pot. Pour in enough salted cold water to cover by 2 inches. Bring to a boil over high heat. Boil until slightly softened, about 5 minutes. Drain and transfer to a large bowl. Toss with the lemon juice and let sit for 15 minutes.

Preheat the oven to 450 degrees F.

Add the oregano, parsley, olive oil, salt, and pepper to the potatoes and toss. Transfer to a shallow baking sheet and roast, stirring occasionally, until golden, about 35 minutes. Sprinkle the potatoes with the paprika. Serve hot.
