Preheat your oven to 425°F (220°C).
In a small bowl, mix together the softened butter, minced garlic, chopped herbs, lemon zest, cajun seasoning, all purpose seasoning, smoked paprika, salt, and pepper until well combined.
Pat the chicken dry with paper towels. Season the cavity of the chicken with salt and pepper, then stuff it with the lemon halves, garlic halves, and a few sprigs of fresh herbs. Gently loosen the skin over the breasts and thighs of the chicken. Spread the compound butter evenly under the skin, making sure to cover as much of the meat as possible. Rub any remaining butter over the outside of the chicken.
Tie the legs together with kitchen twine or aluminum foil of you don't have it and tuck the wings under the body of the chicken.
Place the chicken on a roasting rack in a roasting pan. Roast in the preheated oven for about 1 hour and 15 minutes, basting every 15 minutes, or until the internal temperature reaches 165°F (75°C) and the juices run clear.
Let the chicken rest for about 10-15 minutes before slicing. Enjoy your healthy and delicious meal!
