01 - Set the oven to 400°F and allow it to fully preheat.
02 - Arrange the potato wedges evenly in a large roasting pan.
03 - In a bowl, whisk together extra-virgin olive oil, fresh lemon juice, minced garlic, broth, oregano, sea salt, black pepper, and if desired, ground turmeric.
04 - Pour marinade over the potato wedges and toss thoroughly to ensure even coating. Arrange the wedges with the cut sides down in the pan.
05 - Roast uncovered for 40 minutes.
06 - Remove pan from the oven. Gently turn the potatoes and spoon pan juices over them.

08 - For extra crispiness, set oven to broil for 3 to 5 minutes, carefully watching to prevent burning.
09 - Garnish with chopped fresh parsley and lemon slices just before serving. Serve hot.
