Preheat your oven to 350 degrees Fahrenheit.
This ensures even cooking for your turkey wings.
In a casserole dish, arrange the turkey wings and sprinkle them with the chopped onion.
Season both sides with seasoned salt, poultry seasoning, and black pepper.
In a skillet, melt the butter and add the minced garlic.
Cook until the garlic becomes fragrant and tender.
Pour the chicken stock and the garlic-butter mixture over the turkey wings, covering them well with the liquid.
This will add moisture and flavor to your dish.
Cover the dish tightly with foil and bake in the oven for 2 hours.
This allows the flavors to meld and the turkey to become tender.
