Preheat your oven to 375°F (190°C) and lightly grease a 9x13-inch baking dish.
In a large bowl, whisk together the chicken broth, cream, cream of chicken soup, sun-dried tomatoes, spinach, and half of all the seasonings (reserve the other half for the chicken): Italian seasoning, garlic powder, onion powder, paprika, red pepper flakes, salt, and pepper.
Stir in the uncooked rice until everything is evenly combined, then pour the mixture into your prepared baking dish.
Pat the chicken dry with paper towels. Rub each piece with a little of the oil from the sun-dried tomatoes jar (hello, flavor!) and sprinkle evenly with the remaining seasonings. Lay the chicken pieces right on top of the rice mixture.
Cover tightly with foil and bake for 1 hour to 1 hour and 15 minutes, or until the rice is tender and the chicken reaches 165°F internally.
Let the dish rest for 5–10 minutes before serving—this helps the sauce thicken up a bit. Garnish with Parmesan cheese, and if you’re feeling fancy, a sprinkle of fresh basil or parsley.
