How to Make Chicken Fajita Casserole
Step 1: Preheat the Oven
Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish to prevent sticking.
Step 2: Mix the Ingredients
In a large mixing bowl, combine shredded chicken, bell peppers, onion, chili powder, cumin, garlic powder, smoked paprika, salt, and black pepper. Stir in the diced tomatoes with green chilies and sour cream until everything is evenly coated.
Step 3: Assemble the Casserole
If using rice or cauliflower rice, spread it evenly at the bottom of the baking dish. Then, pour the chicken mixture on top, spreading it out evenly.
Step 4: Add the Cheese & Bake
Sprinkle shredded cheddar and Monterey Jack cheese over the top. Bake uncovered for 20-25 minutes, or until the cheese is melted and bubbly.
Step 5: Serve and Enjoy
Let the casserole cool for about 5 minutes before serving. Garnish with fresh cilantro, avocado slices, or a dollop of sour cream if desired.
