Add the chicken, sausage, rice, bell pepper, onion, celery, garlic, and diced tomatoes into the slow cooker.
Pour in the chicken broth and sprinkle over the paprika, thyme, cayenne, salt, and black pepper.
Stir everything together gently so the flavors start mingling.
Cover and cook on low for 4 to 5 hours, or until the rice is tender and the liquid is mostly absorbed.
Give it a gentle stir, serve hot, and let everyone dig in!
