What You Need to Gather

• 1/2 cup finely diced onion
• 1 red bell pepper, diced
• 1 cup uncooked parboiled long-grain brown rice (can also use long grain white rice)
• 3 tablespoons fajita seasoning (homemade or store-bought)
• 1/8 teaspoon cayenne pepper (optional)
• 1 cup corn kernels (frozen)
• 1 14-ounce can low sodium black beans (drained and rinsed)
• 5 cups shredded chicken
• 3 cups reduced sodium chicken broth
• 1 4-ounce can mild green chilies
• 1 tablespoon olive oil
• 2 tablespoons tomato paste
• 1 1/4 cups shredded Monterey Jack cheese

How to Assemble and Bake

1. Preheat oven to 400°F.
2. Finely dice the onion and red bell pepper.
3. In a 9×13-inch baking dish, combine the diced onion, diced red bell pepper, uncooked rice, fajita seasoning, and cayenne pepper; stir to mix.

4. In a bowl or measuring cup, whisk together the chicken broth, mild green chilies, tomato paste, and olive oil until smooth.

   

5. Pour the broth mixture over the rice and vegetable mixture in the baking dish and stir to combine.
6. Add shredded chicken, drained and rinsed black beans, and frozen corn; stir to distribute evenly.
7. Cover the casserole tightly with aluminum foil and bake 65–70 minutes, until the liquid is absorbed and the rice is tender.

8. Remove the foil and sprinkle shredded Monterey Jack cheese evenly over the top.

9. Bake uncovered an additional 5–10 minutes until the cheese is melted, bubbly, and lightly golden.

10. Remove from the oven and let the casserole rest 5–10 minutes to set before serving.

Tips for Perfect Texture

Make sure your baking dish is well covered to keep the moisture in, and don’t rush the resting time after baking—that lets the rice fully absorb those lovely flavors. Using parboiled rice helps it cook evenly and absorb liquid without turning mushy.

Easy Swaps and Add-Ins

This casserole is a complete meal on its own, but I love pairing it with a fresh salad like a Tossed Green Salad or zesty Cilantro Lime Slaw—or a bright Street Corn Salad with Greek Yogurt—to round out the plate.

Want extra fiber and flavor? Stir in some refried beans and sautéed veggies like bell peppers or zucchini before baking.

Recipe Variations

• Swap the protein: Replace shredded chicken with ground beef or cooked turkey for a tasty twist on the burrito casserole.
• Vegetarian option: Use your favorite plant-based protein like crumbled tofu or add extra chickpeas for a filling meatless meal.
• Dairy-free: No problem! Simply use dairy-free cheese or leave the cheese out and add a dollop of guacamole or salsa on top for creaminess and flavor.

Storing, Freezing, and Reheating

For the fridge: Store leftover casserole in an airtight container and keep it refrigerated. Divide into meal prep containers for easy grab-and-go lunches or dinners; if you’re batching lunches, this High Protein Creamy Chicken Bacon Ranch Pasta is another great meal-prep option. To reheat, microwave for 3-4 minutes until piping hot, then add your favorite fresh toppings.

For the freezer: Cool your cooked casserole completely before transferring it to a freezer-safe container. You can freeze leftovers for up to 3 months. To enjoy, thaw overnight in the fridge, then reheat in the microwave or oven until warmed through. Fresh toppings make it extra tasty after reheating, or pair it with a crunchy side like Cucumber Ranch Crack Salad!
