Preheat the oven to 425˚F. Pat the chicken dry and place in a 9x12 baking dish.
In a small bowl, stir together the za'atar, olive oil, salt and pepper. Rub the za'atar seasoning well into the chicken all over. Scatter the red onions all over.
Roast until the chicken is cooked to an internal temperature of 165°F, 35 to 40 minutes. Broil for an additional 2-4 minutes until the chicken is browned.
Garnish with fresh chopped parsley and serve with potatoes, rice pilaf or salad.
Notes
Storage:Store leftover chicken in an airtight container in the fridge for up to 3-4 days, or freeze for up to 3 months. Thaw in the fridge and reheat in a preheated 350-degree oven until heated through. You can also reheat it in an air fryer for 5-6 minutes.Tips:Get extra crispy skin. While roasting should give you an evenly baked chicken, you may want to add a nice crisp top to the skin by broiling for just a few minutes.Use a thermometerto check for doneness. Because we're using bone-in chicken drumsticks and thighs, it's best to get right next to the bone to make sure it is cooked through.
