How to Make One Pot Mexican Rice Casserole

Step 1: Sauté Aromatics

Start by heating a splash of oil in a large pot over medium heat. Add finely chopped onions and minced garlic, cooking until they soften and release their wonderful aroma, which forms the flavor base for the casserole.

Step 2: Toast the Rice

Next, stir in the uncooked rice and toast it lightly with the onions and garlic for a few minutes. This step adds a subtle nuttiness and helps prevent the rice from sticking later.

Step 3: Add Liquids and Spices

Pour in the broth along with diced tomatoes, black beans, corn, chili powder, cumin, salt, and pepper. Stir well to combine everything evenly before bringing the mixture to a gentle boil.

Step 4: Simmer Until Cooked

Reduce the heat to low, cover the pot, and let it simmer until the rice is tender and has absorbed all the liquid—usually about 20 minutes. Avoid lifting the lid too often to allow the rice to steam perfectly.

Step 5: Finish with Cheese and Cilantro

Once cooked, sprinkle the shredded cheese over the top and cover again for a few minutes until it melts. Finally, garnish with freshly chopped cilantro to brighten up the flavors.

Pro Tips for Making One Pot Mexican Rice Casserole

• Choose the Right Rice: Long-grain white rice works best as it stays fluffy and doesn’t clump.
• Don’t Skip Toasting: Toasting rice before simmering enhances flavor and texture significantly.
• Layer Flavors: Build flavor gradually with aromatics, spices, and fresh toppings.
• Avoid Overcooking: Keep an eye on the simmer time to prevent soggy rice.
• Add Freshness: A squeeze of lime juice at the end can brighten up the whole dish.

Garnishes

A handful of chopped fresh cilantro, a dollop of sour cream or Greek yogurt, sliced avocado, and a sprinkle of diced green onions make the perfect finishing touches that add color and fresh flavors.

Make Ahead and Storage

Storing Leftovers

Let the casserole cool completely before transferring it into an airtight container; it keeps well in the fridge for up to 4 days without losing its flavor or texture.

Freezing

If you want to save it for later, portion the casserole into freezer-safe containers and freeze for up to 3 months—just thaw overnight in the refrigerator before reheating.

Reheating

Reheat leftovers gently in the microwave or on the stovetop with a splash of broth or water to keep it moist and creamy, stirring occasionally until warmed through.
