How to Make One Pot Mexican Rice Casserole

Step 1: Sauté the aromatics

Start by heating a splash of oil in a large pot over medium heat. Add diced onions and minced garlic, cooking until they soften and become fragrant—this base builds the foundation for all the delicious flavors to come.

Step 2: Add the vegetables and seasoning

Stir in diced bell peppers and your Mexican seasoning blend, allowing the spices to toast briefly and release their aromas. This step wakes up the flavors and adds complexity.

Step 3: Incorporate rice and liquids

Add the long-grain white rice to the pot, stirring to coat it in the spices and oil. Pour in the chicken broth and diced tomatoes with green chilies, then bring everything to a gentle boil.

Step 4: Simmer and cook

Reduce heat to low and cover the pot. Let it simmer for about 20 minutes until the rice is tender and the liquid is absorbed. Avoid stirring too much to get perfect, fluffy rice.

Step 5: Add beans and cheese

Fold in the black beans and sprinkle cheese on top. Cover the pot again and cook for a few more minutes until the cheese melts into a creamy, irresistible layer.

Step 6: Garnish and serve

Finish your casserole with a squeeze of fresh lime juice and a handful of chopped cilantro for that fresh, tangy pop that brightens the entire dish.

Pro Tips for Making One Pot Mexican Rice Casserole

  • Use fresh spices: Freshly ground or high-quality pre-mixed Mexican seasoning makes a noticeable difference in flavor.
  • Don’t rush the simmering: Let the rice cook undisturbed for fluffy and perfectly textured grains.
  • Toast the rice lightly: Stirring rice briefly in oil before adding liquid adds a subtle nutty flavor and keeps grains separated.
  • Layer flavors: Add aromatics first, then vegetables, and seasoning gradually to build complexity in every bite.
  • Adjust liquid amount: Depending on your rice and pot, you might need a little more or less broth for the perfect consistency.

How to Serve One Pot Mexican Rice Casserole

Garnishes

Toppings like diced avocado, sour cream, extra shredded cheese, or sliced green onions make this casserole even more irresistible and add contrasting textures.

Side Dishes

Serve alongside fresh salads, warm tortillas, or a zesty corn salsa to round out the meal with freshness and crunch.

Creative Ways to Present

For party-ready portions, spoon the casserole into small ramekins or stuff it into bell pepper halves before baking for a festive and fun presentation.

Make Ahead and Storage

Storing Leftovers

Let your casserole cool completely before transferring it to airtight containers; it keeps well refrigerated for up to 4 days, making quick lunches or dinners easy to reheat.

Freezing

This dish freezes beautifully—portion it out, wrap tightly, and freeze for up to 3 months. Thaw overnight in the fridge before reheating to maintain texture and flavor.

Reheating

Reheat gently on the stovetop or in the microwave, adding a splash of broth or water to keep the rice moist and prevent dryness.
