Gathering Your Ingredients for Cheesy Mexican Rice Casserole

Let’s talk ingredients! This Cheesy Mexican Rice Casserole boasts a harmonious blend of textures and tastes, creating a satisfying and flavorful experience. The combination of hearty rice, creamy beans, zesty tomatoes, and sweet corn, all blanketed in melted cheese, is simply irresistible. Here’s a breakdown of what you’ll need:

The Foundation:

  • 2 cups cooked rice: This is the star of our casserole. Using pre-cooked rice is crucial for preventing a soggy casserole. Day-old rice works perfectly! Feel free to use your favorite type of rice – long-grain, basmati, or even brown rice for a nuttier flavor. You can even cook it in a flavorful broth like our golden rice pilaf for an extra layer of deliciousness.

Flavor Builders:

  • 1 can (15 ounces) black beans, rinsed and drained: Black beans add a hearty and earthy element to the casserole, contributing both flavor and protein. Rinsing and draining them removes excess starch and helps prevent the casserole from becoming too watery.
  • 1 can (10 ounces) diced tomatoes and green chilies, undrained: These provide a zesty and slightly spicy kick to the casserole. Using the undrained can adds moisture and intensifies the tomato flavor.
  • 1 cup corn kernels (fresh, frozen, or canned): Corn adds a touch of sweetness and a pleasant texture. Fresh corn, cut off the cob, is fantastic when in season. Frozen corn is a convenient and readily available alternative. Canned corn, drained, works in a pinch.
  • 1/2 cup diced onion: Onion provides a savory foundation for the other flavors. Dicing it finely ensures it cooks evenly and blends seamlessly into the casserole.
  • 1 teaspoon chili powder: Chili powder adds depth and warmth. Adjust the amount to your desired level of spiciness.
  • 1/2 teaspoon cumin: Cumin lends a smoky and earthy note that complements the other Mexican-inspired flavors perfectly.
  • Salt and pepper to taste: Seasoning is key to bringing out all the flavors. Be sure to taste and adjust as needed.

The Grand Finale:

  • 2 cups shredded cheddar cheese: Cheddar cheese provides a classic cheesy flavor and melts beautifully. Feel free to experiment with other cheeses like Monterey Jack, Colby Jack, or a Mexican blend.
  • 1/4 cup chopped cilantro, for garnish: Fresh cilantro adds a bright and herbaceous finish to the casserole. If you’re not a fan of cilantro, you can substitute with chopped parsley or green onions.

Crafting Your Cheesy Mexican Rice Casserole: Step-by-Step

Ready to get cooking? Don’t worry, this Cheesy Mexican Rice Casserole is super simple to make. The most important thing is to ensure your rice is already cooked before you begin assembling the casserole. This guarantees a perfect, non-soggy texture every time!

  1. Preheat your oven to 350 degrees F (175 degrees C). Getting the oven preheated ensures the casserole bakes evenly and the cheese melts beautifully.
  2. In a large bowl, combine the cooked rice, black beans, diced tomatoes and green chilies, corn, diced onion, chili powder, cumin, salt, and pepper. Mix well. This is where all the magic happens! Make sure everything is evenly distributed so each bite is bursting with flavor. Don’t be afraid to give it a good stir!
  3. Spread half of the rice mixture into a lightly greased casserole dish. A greased dish prevents the casserole from sticking and makes serving easier. I like to use a 9×13 inch dish for this recipe, but any similar-sized casserole dish will work.
  4. Sprinkle with half of the shredded cheddar cheese. This layer of cheese adds a gooey and delicious element to the casserole. Make sure to spread it evenly for maximum cheesy goodness!
  5. Spread the remaining rice mixture over the cheese. We’re building layers of flavor and texture here! Make sure the rice mixture is evenly distributed over the cheese layer.
  6. Top with the remaining shredded cheddar cheese. This final layer of cheese will melt and bubble in the oven, creating a golden-brown and irresistible topping.
  7. Bake in the preheated oven for 20-25 minutes, or until the cheese is melted and bubbly. Keep an eye on the casserole during baking to prevent the cheese from burning. You want it to be perfectly melted and slightly golden.
  8. Garnish with chopped cilantro before serving. This adds a fresh and vibrant finishing touch to the casserole. The aroma of cilantro will also make your kitchen smell amazing!

Tips for Perfect Cheesy Mexican Rice Casserole Every Time

Want to ensure your Cheesy Mexican Rice Casserole is a resounding success? Here are a few extra tips and tricks:

  • Don’t overbake: Overbaking can dry out the casserole and make the rice tough. Bake just until the cheese is melted and bubbly.
  • Spice it up: Add a pinch of cayenne pepper or a dash of hot sauce to the rice mixture for an extra kick.
  • Make it vegetarian: This recipe is naturally vegetarian!
  • Make it ahead: Assemble the casserole ahead of time and store it in the refrigerator until ready to bake. This is a great option for busy weeknights. You can also check out our slow cooker cheesy potatoes for another make-ahead cheesy dish.
  • Storage: Leftover casserole can be stored in an airtight container in the refrigerator for up to 3 days. Reheat in the microwave or oven until heated through.

What to Serve With Cheesy Mexican Rice Casserole

This Cheesy Mexican Rice Casserole is delicious on its own, but it also pairs well with a variety of side dishes. Consider serving it with a simple green salad, a dollop of sour cream or Greek yogurt, or a side of guacamole and tortilla chips. It also pairs great with our Roasted Sweet Potato Chicken Power Bowl for a complete meal!

Your Cheesy Mexican Rice Casserole Questions Answered (FAQ)
