Ingredients You’ll Need

• 1/2 cup finely diced onion
• 1 red bell pepper, diced
• 1 cup uncooked parboiled long-grain brown rice (long grain white rice also works)
• 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 tomato paste
• 2 tablespoons olive oil
• 1 1/4 cups shredded Monterey Jack cheese

How to Make Easy Chicken Burrito Casserole

Step 1: Combine the dry ingredients.
Preheat the oven to 400°F. Add the diced onion, bell pepper, uncooked rice, fajita seasoning, and cayenne pepper if using to a 9×13 inch baking dish, stirring to combine.

Step 2: Make the liquid mixture.
In a separate bowl or measuring cup, whisk together the chicken broth, green chilies, tomato paste, and olive oil until well combined.

Step 3: Combine the base.
Pour the broth mixture into the baking dish and stir it together with the rice mixture, making sure everything is evenly distributed.

Step 4: Add the protein and remaining ingredients.
Stir in the shredded chicken, black beans, and corn, mixing well until everything is evenly combined throughout the dish.

Step 5: Bake covered.
Cover the baking dish tightly with aluminum foil and bake for 65 to 70 minutes, or until all of the liquid has been absorbed by the rice.

Step 6: Add the cheese.
Remove the dish from the oven, take off the foil, and sprinkle the shredded Monterey Jack cheese evenly over the top.

Step 7: Finish baking.
Return the dish to the oven for a final 5 to 10 minutes, until the cheese has melted and turned slightly golden.

Step 8: Rest and serve.
Let the casserole cool for 5 to 10 minutes before serving. Top with fresh cilantro, green onion, salsa, or avocado, if desired.

• Cook time: 1 hour 20 minutes
• Total time: 1 hour 30 minutes

Tips for the Best Results

• Oven times can vary. The total bake time may depend on your oven, so check at the suggested time and extend if needed.
• If it looks soupy, give it more time. Stir to redistribute the liquid and return it to the oven until most of it has been absorbed — some will continue absorbing into the rice as it rests.
• Fajita seasoning works great here. Homemade or store-bought both work well, and taco seasoning is a good substitute if that’s what you have on hand.
• Use rotisserie chicken for convenience. If you don’t have cooked chicken on hand, a rotisserie chicken or boiled and shredded chicken breasts both work perfectly.
• Let it rest before serving. This short resting period helps the casserole set slightly, making it easier to serve clean portions.

Storage & Reheating

Store leftovers in an airtight container in the fridge for up to 4 days. Reheat individual portions in the microwave, or warm the whole dish covered in a 350°F oven until heated through.

Serving Suggestions

• Topped with fresh cilantro, avocado, and a squeeze of lime
• With a dollop of sour cream and extra salsa
• Alongside tortilla chips for added crunch
• Served with a simple side salad for a lighter addition
