Place wings in a preheated 250℉ oven and bake for 30 minutes. NOTE: After 30 minutes the chicken will NOT be fully cooked – you’re not done yet – the next step is where the magic happens.
Now crank up the oven temp to 425℉ and bake for an additional 40 minutes or until the skin is crispy and lightly browned.
