One Pot Mexican Rice Casserole Recipe Details:
- Preparation time: 15 minutes
- Cooking time: 25 minutes
- Servings: 6-8
- Equipment: Large deep skillet or Dutch oven, measuring cups, wooden spoon
Ingredients:
For the Casserole Base:
- 1 pound ground beef
- 1 tablespoon olive oil (if needed for browning)
- 1 small onion, finely chopped
- 1 red bell pepper, chopped
- 2 cloves garlic, minced
- 1 cup long grain white rice, uncooked
- 1 (10 oz) can diced tomatoes with green chilies (like Rotel), undrained
- 1 ½ cups beef broth
- 1 (15 oz) can black beans, drained and rinsed
- 1 cup frozen corn
- 1 ½ teaspoons chili powder
- 1 teaspoon cumin
- ½ teaspoon smoked paprika
- Salt and black pepper, to taste
- 1 ½ cups shredded cheddar cheese
- Fresh cilantro, chopped (optional for garnish)
Directions:
- In a large deep skillet or Dutch oven over medium-high heat, brown the ground beef until no longer pink, breaking it apart as it cooks. If there's excess grease, carefully drain it off.
- Add the chopped onion and red bell pepper to the beef. Cook for about 3–4 minutes, until the vegetables soften. Stir in the minced garlic and cook for another 30 seconds until fragrant.
- Mix in the uncooked rice, diced tomatoes with juices, and beef broth. Give everything a good stir to ensure nothing sticks to the bottom of the pan.
- Add the black beans, corn, chili powder, cumin, smoked paprika, and season with salt and pepper to taste. Stir until all ingredients are well combined.
- Bring the mixture to a boil, then reduce the heat to low. Cover with a tight-fitting lid and simmer for 18–20 minutes, or until the rice is tender and has absorbed most of the liquid. Stir once or twice while simmering to prevent sticking.
- Once the rice is cooked, sprinkle the shredded cheddar cheese evenly over the top. Cover again and let it sit for 2–3 minutes until the cheese is melted and gooey.
