- Preheat your oven to 350°F. While the oven heats, mix the uncooked rice, chicken broth, Rotel tomatoes, and half the nacho cheese sauce in your baking dish. 
- Pour the heavy cream and the remaining nacho cheese sauce over the top. Gently spread the shredded cheese across the casserole. 
- Cover your dish tightly with aluminum foil, ensuring it traps the heat and steam. Bake for 30 minutes. Then, remove the foil and bake for an additional 10 minutes to brown the cheese slightly. 
- Once baked, allow the casserole to cool for a few minutes. Garnish with chopped cilantro, sliced jalapeños, or fresh pico de gallo for added flair.
