  • 1 pound ground beef or turkey
  • 1 onion, diced
  • 1 bell pepper (any color), diced
  • 2 cloves garlic, minced
  • 1 cup long-grain rice
  • 1 can (15 ounces) black beans, drained and rinsed
  • 1 cup corn kernels (fresh or frozen)
  • 1 can (14 ounces) diced tomatoes
  • 1 can (4 ounces) diced green chilies
  • 1 teaspoon chili powder
  • 1 teaspoon cumin
  • 1/2 teaspoon paprika
  • Salt and pepper to taste
  • 2 cups chicken or vegetable broth
  • 1 cup shredded cheddar or Mexican blend cheese
  • Fresh cilantro and lime wedges for garnish


  1. Brown the Meat: In a large oven-safe pot or Dutch oven, brown the ground beef or turkey over medium heat until fully cooked. Drain any excess fat.
  2. Sauté Aromatics: Add diced onions, minced garlic, and diced bell pepper to the pot. Sauté until the vegetables are softened and aromatic.
  3. Add Rice and Spices: Stir in the long-grain rice, chili powder, cumin, paprika, salt, and pepper. Allow the rice to toast slightly and absorb the flavorful spices.
  4. Incorporate Beans, Corn, and Tomatoes: Introduce the drained black beans, corn kernels, diced tomatoes (with their juice), and diced green chilies to the pot. Stir until all ingredients are well combined.
  5. Pour in Broth: Pour in the chicken or vegetable broth, ensuring it covers the rice and meat mixture. Bring the pot to a gentle boil.
  6. Simmer to Perfection: Reduce the heat to low, cover the pot, and let it simmer for 15-20 minutes or until the rice is tender and has absorbed the liquid.
  7. Cheese It Up: Preheat your oven’s broiler. Sprinkle shredded cheese evenly over the top of the casserole. Place the pot under the broiler for 2-3 minutes or until the cheese is melted and bubbly.
  8. Garnish and Serve: Remove the pot from the oven and garnish the Mexican Rice Casserole with fresh cilantro. Serve hot with lime wedges on the side for a burst of citrusy freshness.

Cook Notes:

  • To add a smoky flavor, consider using fire-roasted diced tomatoes and smoked paprika.
  • For an extra kick of heat, add a diced jalapeño or a dash of cayenne pepper to the mixture.


1. Vegetarian Twist: Substitute the meat with plant-based alternatives like crumbled tofu or textured vegetable protein for a satisfying vegetarian version.

2. Seafood Extravaganza: Elevate your One-Pot Mexican Rice Casserole by adding cooked shrimp, diced fish, or crab meat for a seafood-infused fiesta.

Keto-Friendly and Low-Carb Versions:

1. Keto Fiesta: For a keto-friendly option, replace the rice with cauliflower rice. Adjust the cooking time to prevent overcooking the cauliflower, keeping it slightly crunchy.
