01 - Set the oven to 400°F (200°C) and allow it to fully preheat.
02 - Arrange 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 optional turmeric until well combined.
04 - Pour the marinade evenly over the potatoes and toss thoroughly to ensure all wedges are well coated. Arrange potatoes cut side down for even roasting.
05 - Roast potatoes uncovered for 40 minutes.
06 - Remove the pan from the oven, carefully flip potato wedges, and spoon pan juices over the top.
07 - Return the pan to the oven and continue roasting for 30 to 35 minutes, until potatoes are golden, crisp on the edges, and tender inside.
08 - For added crispiness, set the oven to broil mode for the final 3 to 5 minutes, monitoring closely to prevent over-browning.
09 - Transfer potatoes to a serving platter, garnish with chopped parsley and lemon slices, and serve hot.
