How to Make One Pot Mexican Rice Casserole

Step 1: Sauté Aromatics

Start by heating oil in a large pot over medium heat. Add diced onion and minced garlic, cooking until softened and fragrant, about 3–4 minutes. This builds the flavorful foundation you want for your casserole.

Step 2: Toast the Rice

Add the rice to the pot and stir frequently, allowing it to toast lightly in the oil and onion mixture. This step helps give the rice a slightly nutty flavor and prevents it from sticking together.

Step 3: Add Liquids and Spices

Pour in the chicken broth, diced tomatoes with green chilies, black beans, and sprinkle your Mexican spice blend. Stir everything together well to evenly distribute the flavors.

Step 4: Simmer the Casserole

Bring the mixture to a gentle boil, then reduce heat to low and cover the pot. Let it simmer for about 20 minutes, or until the rice is tender and the liquid is absorbed. Avoid lifting the lid too often to keep the steam inside.

Step 5: Add Cheese and Garnish

Once the rice is cooked, sprinkle shredded cheese on top and cover for a few minutes to let it melt. Finish with a squeeze of lime juice and fresh cilantro before serving to add brightness and freshness.

Pro Tips for Making One Pot Mexican Rice Casserole

• Use Good Quality Broth: It makes a significant difference in the depth of flavor for your rice.
• Don’t Skip Toasting: Toasting the rice lightly before simmering enhances its aroma and texture.
• Cover While Cooking: This traps steam and cooks the rice evenly without drying out the dish.
• Adjust Spice Levels: Add more chili powder or fresh jalapeños if you crave heat.
• Let it Rest: After cooking, let the casserole sit covered for a few minutes for flavors to meld beautifully.
