01 - Set oven to 400°F and allow it to preheat fully.
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 (if using) ground turmeric.
04 - Pour marinade over the potatoes, tossing to coat each wedge. Arrange all wedges cut side down and mostly flat.
05 - Roast potatoes, uncovered, for 40 minutes.
06 - Remove pan from oven, gently turn each potato wedge, and spoon pan juices over them.
07 - Return pan to oven and roast for an additional 30 to 35 minutes, or until golden, crisp on the edges, and fork-tender.
08 - For enhanced crispiness, broil for 3 to 5 minutes, keeping a close watch to avoid burning.
09 - Add chopped fresh parsley and optional lemon slices before serving. Present hot.
