Ingredients You’ll Need

1 cup uncooked parboiled long-grain brown rice (or long-grain white rice)
3 tablespoons fajita seasoning
1/8 teaspoon cayenne pepper (optional)
1 cup frozen corn kernels
1 (14-ounce) can low-sodium black beans, drained and rinsed
5 cups shredded cooked 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

Optional Toppings

Chopped cilantro
Sliced green onions
Diced avocado
Salsa or pico de gallo
Sour cream or Greek yogurt
Crushed tortilla chips
Fresh lime wedges

Step-by-Step Instructions

Step 1: Preheat the Oven

Preheat your oven to 400°F (200°C).

Step 2: Combine the Dry Ingredients

Add the diced onion, bell pepper, uncooked rice, fajita seasoning, and cayenne pepper (if using) to a 9×13-inch baking dish. Stir everything together until evenly combined.

Step 3: Prepare the Broth Mixture

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

Step 4: Add the Liquid

Pour the broth mixture into the baking dish and stir well so the rice is evenly distributed throughout the liquid.

Step 5: Add the Chicken and Beans

Stir in the shredded chicken, black beans, and corn until everything is thoroughly combined.

Step 6: Bake

Cover the dish tightly with aluminum foil and bake for 65–70 minutes, or until the rice is tender and most of the liquid has been absorbed.

Step 7: Add the Cheese

Remove the foil, sprinkle the shredded cheese evenly over the top, and return the dish to the oven for 5–10 minutes, until the cheese is melted and lightly golden.

Step 8: Let It Rest

Allow the casserole to rest for 5–10 minutes before serving. This helps the rice absorb any remaining liquid and makes it easier to scoop. Serve with your favorite toppings such as cilantro, green onions, salsa, and avocado.

Tips for the Best Chicken Burrito Casserole

Use parboiled rice for the most reliable texture.
Cover the dish tightly so the rice cooks properly.
If the casserole still looks a little wet after baking, stir it once and bake for a few more minutes.
Letting the casserole rest after baking improves the texture significantly.
Rotisserie chicken is the quickest option, but freshly cooked chicken breasts or thighs work just as well.

Make-Ahead Instructions

You can assemble the casserole several hours in advance and refrigerate it until you’re ready to bake. Keep the cheese separate and add it during the final few minutes of baking. If baking directly from the refrigerator, add about 5–10 extra minutes to the covered baking time.

Storage Instructions

Refrigerator

Store leftovers in an airtight container for up to 4 days.

Freezer

Freeze cooled portions in freezer-safe containers for up to 3 months. Thaw overnight in the refrigerator before reheating.

Reheating

Microwave individual portions for 3–4 minutes, or reheat larger portions in a 350°F oven until warmed through.

Recipe FAQs

Is this casserole gluten-free?

Yes, as long as your fajita seasoning and other packaged ingredients are certified gluten-free.

Can I use white rice instead of brown rice?

Yes. Long-grain white rice works well and may cook slightly faster than parboiled brown rice.

Can I make this with uncooked chicken?

It’s best to use fully cooked chicken. Raw chicken would require a different cooking method and timing.

Can I serve this in tortillas?

Absolutely. Spoon the cooked casserole into warm flour or corn tortillas, add extra cheese and toppings, and roll them up like burritos.

What if my casserole is still soupy?

Give it a quick stir and return it to the oven for a few more minutes. Some of the liquid will also continue absorbing as the casserole rests.

What to Serve with Chicken Burrito Casserole

This casserole is filling enough to serve on its own, but it pairs well with:

A crisp green salad
Mexican street corn
Refried beans
Sautéed fajita vegetables
Guacamole and tortilla chips
Fresh fruit salad for a lighter side

Easy Variations

Beef Burrito Casserole

Replace the shredded chicken with cooked ground beef or shredded beef.

Vegetarian Version

Omit the chicken and add an extra can of black beans or pinto beans.

Extra Spicy

Use hot green chilies, add diced jalapeños, or increase the cayenne pepper.

Dairy-Free

Skip the cheese or use your favorite dairy-free shredded cheese alternative.
