Preheat your oven to 400°F (200°C).
Wash and peel the Yukon Gold potatoes, then cut them into quarters or 1-inch thick wedges.
In a mixing bowl, whisk together the chicken stock, extra virgin olive oil, lemon juice, minced garlic, dried oregano, and fine sea salt until well combined.
Place the potato wedges in a large baking dish and pour the marinade over the potatoes, tossing to coat.
Dot the potatoes with small pieces of unsalted butter, cover with aluminum foil, and bake for 30 minutes.
After 30 minutes, remove the foil and roast the potatoes for an additional 30-40 minutes, tossing halfway through.
Once cooked, sprinkle with finely chopped parsley and serve warm.
