01 - Place chicken pieces in a large Dutch oven or heavy pot. Cover with chicken broth, add bay leaf, and season with a pinch of salt. Bring to a boil over high heat, then reduce to medium-low and simmer for 30 minutes, skimming any foam that rises to the surface.
02 - Remove chicken from the pot and allow to cool slightly. Pull off and discard the skin. Remove meat from the bones and shred into bite-sized pieces. Set aside. Discard the bay leaf.
03 - In the same pot, cook sausage slices over medium heat until browned, about 5 minutes. Add onion, garlic, celery, and bell pepper. Sauté until vegetables are softened, about 6 minutes.
04 - Stir in rice, paprika, black pepper, cayenne, and additional salt if desired. Return shredded chicken to the pot and mix well.
05 - Pour in enough reserved broth to cover ingredients (about 6-7 cups). Bring to a gentle boil, then reduce heat to low. Cover tightly and simmer for 25-30 minutes, stirring occasionally, until rice is tender and most liquid is absorbed.
06 - Remove from heat and let stand, covered, for 5 minutes. Fluff with a fork. Garnish with chopped parsley before serving.
