Set your oven to 350°F (175°C) and let it heat while you prep the wings.
Pat turkey wings dry with paper towels. Toss with olive oil, then coat evenly with smoked paprika, garlic powder, onion powder, thyme, salt, pepper, and cayenne (if using). Rub seasoning all over the wings.
For deeper flavor, sear wings in a hot skillet for 2–3 minutes per side until browned. Skip if short on time.
Place the wings in a deep baking dish. Sprinkle chopped onions and minced garlic over the top.
Combine chicken broth, Worcestershire sauce, and melted butter. Pour over the wings so the liquid settles at the bottom.
Cover the dish tightly with foil. Bake for 1½ to 2 hours until the wings are fork-tender.
Remove some liquid, stir with 1 tbsp cornstarch until smooth, then mix it back in to thicken the sauce slightly.
Uncover and broil for 5–10 minutes until the tops are golden and slightly crisp. Keep an eye on them.
Let rest for 5 minutes. Serve with rice, mashed potatoes, or warm cornbread.
