Step-by-Step Guide
Follow these detailed instructions for a perfect Fajita Chicken Casserole every time.
- Preheat and Prep: Begin by preheating your oven to 375°F (190°C). While it heats, dice one green, one red, and one orange bell pepper into uniform, bite-sized pieces.
- Season the Chicken: In a large mixing bowl, combine 1 lb of pre-cooked, shredded chicken with the entire packet of fajita seasoning. Use a fork or your hands to ensure every strand of chicken is evenly coated with the flavorful spices.
- Assemble the Layers: In a standard 9×13 inch casserole dish, create an even layer of the diced peppers. Next, spread the seasoned shredded chicken evenly over the pepper layer.
- Add the Cheese: Sprinkle 1 cup of shredded mozzarella cheese uniformly over the top of the chicken layer, covering it completely for a golden, melted finish.
- Bake to Perfection: Place the uncovered casserole dish in the preheated oven. Bake for 20-25 minutes, or until the cheese is fully melted, bubbly, and just beginning to brown at the edges.
- Final Garnish: Remove the casserole from the oven and let it rest for 5 minutes. This allows the flavors to settle. Top individual servings with a dollop of cool sour cream or fresh guacamole.
Serving Suggestions
This versatile casserole pairs wonderfully with a variety of sides. For a complete Tex-Mex feast, serve it over a bed of cilantro-lime rice or with warm, soft flour tortillas on the side. A simple side salad with a lime vinaigrette or a bowl of black beans complements the dish perfectly. For a low-carb option, serve it alongside cauliflower rice or a fresh pico de gallo.

Frequently Asked Questions
Can I use fresh chicken instead of pre-cooked? Yes. For raw chicken, dice 1 lb of boneless, skinless breasts or thighs, season, and sauté with the peppers until cooked through before assembling and baking.
How can I make this dish spicier? Add a diced jalapeño to the pepper mix, use a spicy fajita seasoning packet, or sprinkle some cayenne pepper or chili flakes with the cheese.
What are the best cheeses to use besides mozzarella? A Mexican blend, pepper jack, or a combination of cheddar and Monterey Jack are excellent alternatives that add great flavor.
Can I prepare this casserole ahead of time? Absolutely. Assemble the dish completely, cover tightly, and refrigerate for up to 24 hours. Add 5-10 minutes to the baking time when cooking from cold.
How should I store and reheat leftovers? Store in an airtight container in the refrigerator for up to 3 days. Reheat portions in the microwave or in a 350°F oven until warmed through.
Common Mistakes to Avoid
- Using Wet Chicken: Ensure your pre-cooked shredded chicken is well-drained and not watery, as excess moisture will make the casserole soggy.
- Uneven Dicing: Dice the peppers uniformly to ensure they cook evenly. Large chunks may remain too crisp.
- Overcrowding the Dish: Use a casserole dish large enough (9×13 inches is ideal) to allow for a shallow, even layer that heats consistently.
- Skipping the Rest Time: Letting the casserole sit for 5 minutes after baking helps the layers set, making it easier to serve neat portions.
