Step‑by‑Step Instructions for Chicken Burrito Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C) to prepare for baking your Chicken Burrito Casserole. This step is crucial for achieving that golden, bubbly top you desire. While the oven heats, gather your ingredients to streamline the cooking process and make the assembly smoother.
Step 2: Prepare the Base
In a 9×13 inch baking dish, combine the finely diced onion, red bell pepper, uncooked parboiled brown rice, fajita seasoning, and cayenne pepper. Mix these ingredients thoroughly. You’ll be greeted by vibrant colors and fragrant aromas—perfectly setting the stage for the layers of flavor in your Chicken Burrito Casserole.
Step 3: Whisk Together the Liquids
In a separate bowl, whisk together the reduced sodium chicken broth, mild green chiles, tomato paste, and olive oil until well combined. This mixture will infuse richness into your casserole. Once blended, pour it over the rice and vegetable mixture in the baking dish, stirring gently to ensure an even distribution of moisture and flavor.
Step 4: Incorporate the Proteins and Corn
Now, add the shredded chicken, black beans, and frozen corn to the baking dish. Mix everything with a sturdy spatula until all the ingredients are well combined. This step ensures that every bite of your Chicken Burrito Casserole is packed with protein, fiber, and delightful texture, all coated in that delicious broth.
Step 5: Cover and Bake
Cover your baking dish tightly with aluminum foil to lock in moisture. Place the dish in the preheated oven and bake for 65-70 minutes. You’ll know it’s done when the rice is tender and has absorbed most of the liquid. The casserole will be bubbling around the edges, indicating it’s cooking beautifully.
Step 6: Add the Cheese Topping
Once the initial baking time is up, carefully remove the foil. The Chicken Burrito Casserole will be steaming and aromatic! Sprinkle the shredded Monterey Jack cheese evenly over the top, creating a cheesy layer that will melt into deliciousness. Return the dish to the oven and bake uncovered for an additional 5-10 minutes until the cheese is melted and lightly golden.
Step 7: Cool and Serve
After baking, let the casserole cool for a brief period before serving. This helps to set the layers. Garnish with fresh cilantro, green onions, salsa, and avocado if desired for an extra splash of color and freshness. Your Chicken Burrito Casserole is now ready to be enjoyed, bringing a joyful and satisfying meal to your table!

Gluten-Free Easy Chicken Burrito Casserole Recipe FAQs
How do I choose the ripeness of my vegetables?
Absolutely! When selecting onions and bell peppers, look for ones that are firm and free from dark spots or blemishes. A good onion should feel heavy for its size and have a dry, papery skin. For bell peppers, vibrant color and a shiny skin indicate freshness. Choose ones that feel heavy and solid, and avoid any that have wrinkled skin or soft spots.
How should I store leftovers of the Chicken Burrito Casserole?
Very! Store your leftover Chicken Burrito Casserole in an airtight container in the fridge for up to 5 days. Simply reheat portions in the oven at 350°F (175°C) until heated through, or in the microwave for a quicker option. Keeping it sealed helps maintain its delicious flavors and texture!
Can I freeze the Chicken Burrito Casserole? If so, how?
Definitely! To freeze, first allow the casserole to cool completely. Transfer it into a freezer-safe container, and it will keep well for 1-3 months. For best results, cover with plastic wrap before sealing with a lid to prevent freezer burn. To reheat, thaw in the fridge overnight and bake at 350°F (175°C) for 20-30 minutes until heated through. If baking from frozen, cook covered with foil until warmed, then remove the foil to crisp the top.
What should I do if my casserole is too soupy after baking?
No worries! If your casserole is still soupy after the initial 70 minutes, simply remove the foil and return it to the oven. Continue baking uncovered for another 10-15 minutes until most of the liquid is absorbed and the casserole becomes thicker. Keeping an eye on it during this final baking will help achieve that desired consistency.
Are there any dietary considerations I should be aware of?
Absolutely! This casserole is gluten-free and can be made vegetarian by substituting the shredded chicken with additional black beans or lentils. If you or your guests have allergies, be cautious with the broth (ensure it’s free from gluten) and check ingredient labels on store-bought items like fajita or taco seasoning. Always feel free to customize ingredients based on dietary needs!
