Ingredients You’ll Need
Here’s what you’ll need to make this Mexican-inspired baked brown rice casserole:
- 2 cups cooked brown rice – Brown rice provides a nutty flavor and a satisfying chewy texture, making it a wholesome base for this dish.
- 1 cup black beans (drained and rinsed) – Packed with protein and fiber, black beans add both heartiness and a subtle earthiness.
- 1 cup corn kernels (fresh, frozen, or canned) – Corn adds a touch of sweetness and a pop of color to the casserole.
- 1 cup diced tomatoes (fresh or canned) – Tomatoes bring juiciness and a tangy flavor that balances the richness of the cheese.
- 1/2 cup finely chopped onion – Onion adds a mild savory flavor that enhances the other ingredients.
- 1/2 cup diced bell pepper (any color) – Bell peppers give crunch, color, and subtle sweetness.
- 1 cup shredded cheddar cheese (or Mexican-style cheese) – Cheese adds a gooey, melty layer that makes this casserole irresistible.
- 1/2 cup salsa (mild, medium, or spicy, according to taste) – Salsa provides moisture and a deliciously tangy, slightly spicy kick.
- 1 teaspoon chili powder – Adds the signature Mexican flavor and a hint of heat.
- 1 teaspoon ground cumin – Cumin brings earthiness and depth to the dish.
- 1/2 teaspoon smoked paprika – Smoked paprika adds warmth and a subtle smoky flavor.
- Salt and pepper to taste – Essential for seasoning.
- 1 tablespoon olive oil – Used to grease the baking dish and add richness.
- 1/4 cup fresh cilantro, chopped (optional) – A fresh garnish that adds color and brightness to the final dish.
Step-by-Step Instructions
Step 1: Preheat Your Oven
Start by preheating your oven to 190°C (375°F). Lightly grease a medium to large baking dish with olive oil or a non-stick cooking spray. This ensures the rice won’t stick and makes cleanup easier.
Step 2: Mix the Rice and Vegetables
In a large mixing bowl, combine the cooked brown rice, black beans, corn, diced tomatoes, onion, and bell pepper.
Next, add the chili powder, cumin, smoked paprika, salt, and pepper. Stir everything together thoroughly so the spices coat the vegetables and rice evenly. This mixture is the heart of the casserole, and the spices will infuse every bite with authentic Mexican flavor.
Step 3: Layer the Casserole
Take half of the rice mixture and spread it evenly in the prepared baking dish.
Pour half of the salsa over the rice and sprinkle half of the shredded cheese on top. This layering technique ensures that every spoonful of the casserole has a perfect balance of rice, vegetables, cheese, and sauce.
Repeat with the remaining rice mixture, salsa, and cheese to create a second layer. This double layer makes the casserole hearty, filling, and visually appealing when served.
Step 4: Bake to Perfection
Cover the baking dish with aluminum foil and bake for 20 minutes. This allows the flavors to meld and the ingredients to heat through evenly.
After 20 minutes, remove the foil and bake for an additional 10–15 minutes. You’ll know it’s ready when the cheese is bubbly and lightly golden brown. This step creates a crispy, flavorful top layer that contrasts beautifully with the tender rice and vegetables below.
Step 5: Garnish and Serve
Once the casserole is done, remove it from the oven and let it rest for 5 minutes. This brief cooling period helps the casserole set slightly, making it easier to serve.
If desired, sprinkle fresh chopped cilantro over the top before serving. The cilantro adds a pop of color and a fresh, herby flavor that complements the spices perfectly.
Tips for the Best Mexican Baked Rice
- Cook the rice perfectly: Use slightly undercooked brown rice if you plan to bake it. This prevents the casserole from becoming mushy.
- Adjust spice levels: Feel free to increase or decrease the chili powder and salsa based on your taste preference. For a milder version, opt for mild salsa.
- Add extra protein: You can mix in cooked chicken, ground turkey, or tofu for a more filling meal.
- Cheese alternatives: Try pepper jack or a Mexican blend for a spicier, more authentic flavor.
- Make it ahead: Prepare the rice mixture the day before and refrigerate. When ready to serve, assemble and bake – perfect for busy weeknights.
Variations to Try
- Vegetarian: This recipe is already vegetarian-friendly, but you can add zucchini, mushrooms, or spinach for more veggies.
- Vegan: Substitute the cheese with a plant-based alternative and ensure the salsa is vegan-friendly.
- Extra Crunch: Sprinkle crushed tortilla chips over the top before baking for added texture.
- One-Pot Version: Cook the rice directly in a deep ovenproof skillet with all the ingredients, then bake for less cleanup.
Serving Suggestions
Mexican-style baked brown rice pairs beautifully with:
- Fresh guacamole or sliced avocado – Adds creaminess and balances the spices.
- Sour cream or Greek yogurt – Provides a cooling contrast to the warm casserole.
- Tortilla chips or warm corn tortillas – Great for scooping and adding texture.
- A simple side salad – Light and fresh, complements the hearty casserole perfectly.
This dish is not only hearty and flavorful but also incredibly versatile. Serve it for lunch, dinner, or even a casual brunch – it works in any scenario where comfort food meets health-conscious cooking.
