How to Make Mexican Rice Casserole: Easy Recipe for a Delicious Dinner
Step 1: Sauté the Aromatics
Heat the olive oil in a large skillet or Dutch oven over medium heat. Add the chopped onion and green bell pepper. Cook until softened for about 5-7 minutes while stirring occasionally. Sautéing these vegetables enhances their natural sweetness and creates a flavorful base for your casserole.
Step 2: Add the Garlic
Stir in the minced garlic and cook for another minute until fragrant. Garlic adds depth and aroma to the dish that makes it irresistible.
Step 3: Toast the Rice
Add the uncooked rice to the skillet with the vegetables. Stir it around gently for about 2 minutes. This step helps toast the rice slightly, enhancing its nutty flavor before cooking.
Step 4: Incorporate the Tomatoes and Chilies
Pour in both cans of diced tomatoes—the regular ones and those with green chilies—and stir well to combine. The juicy tomatoes will infuse moisture into your casserole while adding fresh flavor.
Step 5: Add the Beans and Corn
Now it’s time to include those rinsed black beans and drained corn into the skillet. Stir them in evenly so every bite has a bit of everything!
Step 6: Season Generously
Sprinkle in chili powder, cumin, smoked paprika, salt, and pepper. Mix well to ensure that all ingredients are coated with spices. This step is crucial—it’s where all that delicious flavor comes from! Taste it too; adjust seasonings if needed.
Step 7: Add the Broth
Pour in either chicken broth or vegetable broth depending on your preference. Bring everything to a boil before reducing heat to low. Cover your skillet and let it simmer for about 20 minutes until the rice is cooked through and liquid is absorbed.
Step 8: Preheat Your Oven
While your mixture simmers away happily on the stovetop, preheat your oven to 350°F (175°C).
Step 9: Grease the Baking Dish
Lightly grease a 9×13 inch baking dish using cooking spray or a bit of olive oil so nothing sticks!
Step 10: Transfer the Rice Mixture
Pour your aromatic rice mixture into the prepared baking dish. Spread it out evenly so every part gets baked nicely.
Step 11: Add the Cheese
Sprinkle shredded cheddar cheese and Monterey Jack cheese over top of your rice mixture generously. Who doesn’t love melted cheese?
Step 12: Bake
Bake in your preheated oven for about 20-25 minutes until cheese is melted, bubbly, and golden brown on top!
Step 13: Rest (Optional)
Let your casserole rest for a few minutes before serving; this helps everything set up nicely.
Step 14: Serve
Serve warm with toppings like sour cream, guacamole, chopped cilantro, green onions, or salsa—whatever makes you happy!
And there you have it! A delightful Mexican Rice Casserole perfect any day of the week! Enjoy every bite!
