Creating One-Skillet Mexican Rice Casserole is a breeze if you follow these easy steps:

1. Heat the Oil: In a large skillet, heat the olive oil over medium-high heat.
2. Sauté the Onion and Garlic: Add the diced onion and minced garlic to the skillet. Sauté until the onion becomes translucent, which will take about 3-4 minutes.
3. Brown the Meat: Add the ground beef or turkey to the skillet, breaking it apart with a spatula. Cook until browned and cooked through, around 5-7 minutes.
4. Add the Rice: Stir in the uncooked rice and let it toast for 1-2 minutes, allowing it to absorb the flavors.
5. Mix in Beans and Tomatoes: Add the black beans, diced tomatoes with their juices, and corn into the skillet. Stir to combine everything evenly.
6. Pour in the Broth and Season: Pour the chicken or vegetable broth over the mixture. Sprinkle in the chili powder, cumin, salt, and pepper to taste. Stir everything together until well combined.
7. Simmer: Bring the mixture to a boil, then reduce the heat to low. Cover the skillet and let it simmer for about 20-25 minutes or until the rice is tender and the liquid is absorbed.
8. Add Cheese: Once the rice is cooked, remove the skillet from heat. Sprinkle the shredded cheese on top, covering it evenly. Cover again and let it sit for 3-5 minutes until the cheese melts.
9. Garnish: Once the cheese has melted, sprinkle with fresh cilantro if desired.
10. Serve: Serve hot with lime wedges on the side for an extra burst of flavor.

By following these steps, you’ll find that making this casserole is not only easy but also incredibly satisfying!
