Preheat your oven to 350°F (175°C).
In a large skillet, brown the ground beef over medium heat until fully cooked, breaking it apart as it cooks.
Stir in the diced tomatoes, ranch dressing mix, garlic powder, onion powder, salt, and pepper, mixing well.
Add the rice and beef broth, stirring to combine everything evenly.
Transfer the beef and rice mixture into a greased 9x13-inch baking dish.
Top the mixture with shredded cheddar cheese evenly across the surface.
Cover the baking dish with aluminum foil and bake for 30 minutes, then remove the foil and bake for an additional 15 minutes until the cheese is melted and bubbly.
Remove from the oven, let it stand for 5-10 minutes before serving.
