Step‑by‑Step Instructions for Easy Chicken Burrito Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C). This ensures that when your Easy Chicken Burrito Casserole is ready to go in, it will cook evenly and reach the perfect bubbly state. While the oven heats, gather your ingredients and a 9×13 inch baking dish to make the assembly process smooth and enjoyable.
Step 2: Prepare the Base
In the prepared baking dish, combine the finely diced onion, diced red bell pepper, uncooked parboiled brown rice, fajita seasoning, and cayenne pepper. Stir these colorful ingredients together until evenly mixed. The aromatic vegetables and spices will create a fragrant base, providing essential flavor for your casserole.
Step 3: Mix the Liquids
In a separate bowl, whisk together the reduced sodium chicken broth, mild green chiles, tomato paste, and olive oil until well blended. Pour this zesty mixture over the rice and vegetables in your baking dish, ensuring every grain is coated. This mixture will provide the moisture needed for the rice to cook beautifully.
Step 4: Add the Main Ingredients
Next, fold in the shredded chicken, black beans, and frozen corn into the casserole mixture. Stir well to combine everything thoroughly, distributing the protein-packed ingredients evenly throughout the dish. This step will enhance the heartiness of your Easy Chicken Burrito Casserole, making it satisfying for everyone.
Step 5: Bake Covered
Cover the baking dish tightly with aluminum foil, ensuring no steam escapes. Place it in the preheated oven and bake for 65-70 minutes. During this time, the rice will absorb the flavorful broth and become tender. Keep an eye on it, and check for doneness by making sure most of the liquid is absorbed by the end of baking.
Step 6: Add Cheesy Topping
Once the initial baking time is complete, carefully remove the foil and sprinkle shredded Monterey Jack cheese evenly over the top of the casserole. Return it to the oven uncovered and bake for an additional 5-10 minutes. Watch closely until the cheese melts and turns a lovely golden color, adding creaminess to your Easy Chicken Burrito Casserole.
Step 7: Cool and Garnish
After baking, allow the casserole to cool for 5-10 minutes before serving. This resting period will make serving easier and allows the flavors to settle. Before plating, garnish with chopped fresh cilantro, sliced green onions, salsa, and avocado as desired, adding a fresh and colorful touch to your comforting casserole.

Easy Chicken Burrito Casserole Recipe FAQs
How do I choose ripe ingredients for my casserole?
