In a large bowl, add the chicken quarters and drizzle them with olive oil. Add the salt, pepper, garlic powder, paprika, parsley, chicken bullion and onion powder.
Then, add the minced garlic, lemon juice and tomato paste. Massage the seasonings into the chicken until the legs are evenly coated. Try to lift the skin and get it under the skin, also.
Cover the bowl, and place it into the refrigerator for 30 minutes- a couple of hours.
When you’re ready to cook the chicken, preheat the oven to 350°.
Line a baking dish with the lemon and onion slices. Place the chicken on top and top them with the pats of butter.
Pop it into the center rack of the oven, covered for 30 minutes.
Increase the oven temperature to 400° and baste the chicken in all the juices from the bottom of the pan. Place it back into the oven, uncovered for another 25-30 minutes or until the skin is crispy and the chicken is cooked all the way through.
Let the chicken rest for ten minutes before serving, add some of the sauce created when the chicken was cooking and enjoy!
