01 - Preheat the oven to 400°F (200°C).
02 - Arrange the potato wedges evenly in a large roasting pan.
03 - In a mixing bowl, whisk together olive oil, lemon juice, minced garlic, broth, oregano, sea salt, black pepper, and turmeric if using.
04 - Pour the marinade over the potatoes and toss thoroughly to coat. Lay the wedges primarily flat, cut side down.
05 - Roast uncovered for 40 minutes.
06 - Remove the pan from the oven, gently turn the potatoes, and spoon over pan juices.
07 - Return to the oven and roast for an additional 30 to 35 minutes, until the potatoes are golden, crisp on the edges, and fork-tender.
08 - For extra crispiness, set the oven to broil for the final 3 to 5 minutes, monitoring closely to prevent burning.
09 - Garnish with fresh chopped parsley and lemon slices before serving. Serve hot.
