Step 1: Cook the Rice

Begin by cooking the rice according to the package instructions. Use long-grain white rice for this dish, as it will hold up better in the casserole. Set the cooked rice aside.

Step 2: Brown the Ground Beef

In a large skillet, heat the olive oil over medium heat. Add the chopped onion and garlic, and sauté until fragrant and softened, about 2-3 minutes. Add the ground beef to the skillet and cook, breaking it up with a spatula, until it’s browned and cooked through, about 6-8 minutes. Drain any excess grease.

Step 3: Season the Meat

Once the beef is browned, add the taco seasoning packet (or your homemade taco seasoning mix), diced tomatoes with green chilies, black beans, and corn (if using). Stir in the beef broth, cumin (if using), and season with salt and pepper to taste. Let the mixture simmer for about 5 minutes until slightly thickened.

Step 4: Combine with Cooked Rice

Once your taco meat mixture is ready, combine it with the cooked rice in the skillet, stirring to incorporate everything evenly. The rice will absorb all the delicious taco flavors, making each bite satisfying and flavorful.

Step 5: Layer the Casserole

Preheat your oven to 375°F (190°C). In a large baking dish, spread half of the rice and beef mixture across the bottom in an even layer. Sprinkle 1 cup of shredded cheddar cheese over this layer. Then, add the remaining rice and beef mixture on top of the cheese, followed by the final 1 cup of cheddar cheese.

Step 6: Bake to Perfection

Cover the casserole dish with aluminum foil and bake in the preheated oven for 20 minutes. After 20 minutes, remove the foil and bake for an additional 10 minutes, or until the cheese is fully melted and bubbly with a slight golden brown color.

Step 7: Add Taco Toppings

Once baked, remove the Cheesy Taco Rice Bake from the oven and let it cool for a few minutes. Now comes the fun part—adding all your favorite taco toppings! Spread dollops of guacamole and sour cream over the casserole, and sprinkle it with shredded lettuce, diced tomatoes, cilantro, and jalapeños. Finish it off with a squeeze of fresh lime juice for a zesty kick.
