Preheat oven to 375 degrees Fahrenheit

Combine salt, ground black pepper, and garlic powder then mix.

Rub the mixture around the chicken.

Combine melted butter, dried thyme, and lemon zest and mix well.

Loosen the skin of the chicken and spread the lemon zest-butter-thyme mixture in between the skin and flesh.

Stuff the quartered lemon, celery stalks, and onion in the chicken and secure by tying the legs together using a kitchen thread.

Bake / Roast for 60 to 65 minutes.

Turn the oven off and take the chicken out.

Remove the thread and place in serving plate.
