Equipment

  • Large deep skillet or sauté pan (with lid)
  • Wooden spoon or spatula
  • Cutting board
  • Sharp Knife
  • Measuring cups and spoons
  • Can Opener
  • Cheese grater (optional)

Ingredients
  

For the Mexican Rice Casserole

  • 1 ½ cups long-grain white rice
  • 1 tablespoon olive oil
  • 1 small onion finely chopped
  • 3 cloves garlic minced
  • 1 lb ground beef or ground turkey
  • 1 can 14 oz diced tomatoes
  • 1 can 8 oz tomato sauce
  • 2 ½ cups chicken broth
  • 1 cup corn kernels fresh, frozen, or canned
  • 1 can 15 oz black beans, drained and rinsed
  • 1 tablespoon taco seasoning
  • 1 teaspoon ground cumin
  • 1 teaspoon paprika
  • ½ teaspoon chili powder adjust to taste
  • Salt and black pepper to taste
  • 1 cup shredded cheddar cheese optional, for topping
  • Fresh cilantro for garnish

Instructions
 

Step 1: Sauté the aromatics

  • Heat the olive oil in a large deep skillet over medium heat. Add the chopped onion and cook for about 3–4 minutes, stirring occasionally, until it softens and becomes slightly translucent. Add the minced garlic and cook for another 30 seconds until fragrant.
  • Pro tip: Don’t let the garlic brown too much—it can turn bitter quickly and affect the overall flavor of the dish.

Step 2: Brown the meat

  • Add the ground beef (or turkey) to the skillet. Break it apart using a wooden spoon and cook until fully browned, about 5–7 minutes. Drain excess grease if needed.
  • Season lightly with salt and black pepper while it cooks so the flavor builds from the start.

Step 3: Add the spices and tomato base

  • Stir in the taco seasoning, cumin, paprika, and chili powder. Mix well so the meat is evenly coated. Then pour in the diced tomatoes and tomato sauce, stirring everything together until combined.
  • Pro tip: Let the spices cook for about a minute before adding the liquids—it helps deepen the flavor instead of it tasting flat.

Step 4: Add rice and broth

  • Pour in the uncooked rice and chicken broth. Stir everything well to make sure the rice is fully submerged in the liquid and evenly distributed across the pan.
  • Bring the mixture to a gentle boil.

Step 5: Simmer until rice is tender

  • Once it starts boiling, reduce the heat to low and cover the skillet with a tight-fitting lid. Let it simmer for about 18–22 minutes, or until the rice is fully cooked and has absorbed most of the liquid.
  • Pro tip: Avoid stirring while it simmers—this helps the rice cook evenly and prevents it from turning mushy.

Step 6: Add beans and corn

  • Once the rice is tender, gently stir in the black beans and corn. Let everything heat through for another 3–5 minutes on low heat.
  • This is where the casserole starts to feel really hearty and full.

Step 7: Finish with cheese and garnish

  • Sprinkle shredded cheddar cheese over the top if using. Cover the skillet again for 2–3 minutes until the cheese melts beautifully. Remove from heat and finish with fresh cilantro.
  • Serve warm and enjoy your one pot Mexican rice casserole while it’s creamy, flavorful, and comforting.
