For a delicious Southern baked chicken and dressing, start by preheating your oven to 350°F. Season four chicken thighs with salt, pepper, and your favorite spices, then place them in a greased baking dish. In a separate bowl, combine one package of cornbread mix with one cup of chicken broth, half a cup of chopped onion, and half a cup of chopped celery. Pour this mixture over the chicken in the baking dish. Cover with foil and bake for about 45 minutes. Remove the foil and bake for an additional 15 minutes, allowing the chicken to brown and the dressing to soak up all the flavors. Serve hot and enjoy a comforting Southern classic.
