In a large bowl, add your freshly cleaned + rinsed chicken along with onion powder, garlic powder, cayenne peppers, black pepper, thyme, brown sugar, allspice, parsley, smoked paprika, red pepper flakes, cinnamon, nutmeg, cloves, and cumin, mixing everything together until chicken is fully coated. Let it sit for 10-15 minutes. NOTE: For best results, it's best to marinate chicken overnight in the refrigerator.
