Step‑by‑Step Instructions for High-Protein Chicken Burrito Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C). This step is crucial as it ensures that your High-Protein Chicken Burrito Casserole bakes evenly and achieves that delightful golden finish. While the oven heats up, gather your ingredients to prepare for the next steps.
Step 2: Combine the Base Ingredients
In a 9×13 inch baking dish, combine the finely diced onion, red bell pepper, uncooked long-grain brown rice, fajita seasoning, and cayenne pepper (if using). Mix these colorful ingredients thoroughly, ensuring the rice is evenly coated with the seasoning. This blend will serve as the flavorful base for your casserole.
Step 3: Prepare the Broth Mixture
In a separate mixing bowl, whisk together the reduced sodium chicken broth, mild green chiles, tomato paste, and olive oil until the ingredients are well combined and smooth. This flavorful liquid will infuse your High-Protein Chicken Burrito Casserole with moisture and depth, making every bite irresistible.
Step 4: Combine Rice and Broth Mixtures
Pour the broth mixture over the rice and vegetable mixture in the baking dish. Stir well to ensure that all the ingredients are evenly distributed and that the rice is submerged in the liquid. This step is essential for achieving the perfect texture, as the rice needs the moisture to cook properly.
Step 5: Add Remaining Ingredients
Next, gently fold in the shredded chicken, black beans, and frozen corn kernels into the mixture. Stir until everything is evenly combined, ensuring that each ingredient contributes its flavor and texture to your hearty High-Protein Chicken Burrito Casserole.
Step 6: Cover and Bake
Cover the baking dish tightly with aluminum foil and place it in the preheated oven. Bake for 65-70 minutes until the liquid is absorbed and the rice is tender. This covered baking allows the casserole to steam, ensuring a moist and flavorful dish while avoiding dryness.
Step 7: Add Cheese and Finish Baking
After the initial baking time, carefully remove the foil and sprinkle a generous layer of shredded Monterey Jack cheese over the top of the casserole. Return the dish to the oven uncovered and bake for an additional 5-10 minutes until the cheese is melted and slightly golden, creating a deliciously gooey topping.
Step 8: Cool and Serve
Once your High-Protein Chicken Burrito Casserole is out of the oven, let it cool for about 5-10 minutes. This cooling period allows the flavors to meld beautifully. Serve the casserole warm, garnishing with fresh cilantro, green onion, salsa, and avocado if desired for an extra burst of flavor and freshness.

Make Ahead Options
These High-Protein Chicken Burrito Casserole is perfect for meal prep enthusiasts! You can prepare the entire casserole up to 24 hours in advance by assembling all the ingredients in your baking dish, covering it tightly, and refrigerating. For the best quality, ensure the dish is well-sealed to prevent drying out. When ready to cook, simply bake it straight from the fridge, adding an extra 10-15 minutes to the baking time to account for the chill. Alternatively, you can cook and freeze individual portions for up to 3 months.

High-Protein Chicken Burrito Casserole Recipe FAQs
How do I choose the best ingredients for my casserole?
Absolutely! When selecting your onion and bell pepper, opt for ones that are firm and free of dark spots. For the rice, uncooked parboiled long-grain brown rice is ideal as it cooks perfectly. Ensure your shredded chicken is either rotisserie or freshly cooked and tender; aim for chicken breast without any gristle for the best flavor.

Leftovers of your High-Protein Chicken Burrito Casserole can be stored in an airtight container in the fridge for up to 4 days. Be sure to let the casserole cool completely before sealing, as this helps to maintain its delicious flavor and texture.

Yes, you can easily freeze this casserole! I recommend portioning it into individual servings. Wrap each portion tightly in plastic wrap, then cover with aluminum foil or place in freezer-safe containers. This way, you can enjoy it for up to 1-3 months without compromising quality.
