Preheat the oven to 350°F.
Add the rice, chicken broth, shredded chicken, salsa, and taco seasoning to a 9x13 casserole dish. Stir well and spread into an even layer.
Sprinkle the shredded cheese evenly over the top.
Cover tightly with foil and bake for 45 minutes.
Uncover and check the rice. If it isn't tender yet, bake uncovered for another 10 minutes.
Warm the queso in a microwave-safe bowl until smooth and pourable, then pour it over the casserole and serve.
