01 - Set the oven to 400°F (200°C) and allow it to preheat completely.
02 - Arrange the potato wedges evenly in a large roasting pan, ensuring a single layer.
03 - In a mixing bowl, whisk together olive oil, lemon juice, minced garlic, broth, oregano, sea salt, black pepper, and optional turmeric until thoroughly combined.
04 - Pour the marinade over the potatoes and toss well to coat. Position the wedges with their cut sides down for optimal roasting.
05 - Roast uncovered for 40 minutes. Remove from the oven, gently flip each wedge, and baste with pan juices.
06 - Return to the oven and roast an additional 30 to 35 minutes, or until potatoes are golden, crisp along the edges, and fork-tender.
07 - For extra crispness, activate the oven broiler for the final 3 to 5 minutes, monitoring closely to prevent burning.
08 - Transfer potatoes to a serving dish and garnish with fresh parsley and lemon slices. Serve hot.
