For the Casserole

- ½ cup chopped fresh cilantro (optional, for garnish)
Instructions
Step 1: Preheat and Prep
- Preheat your oven to 375°F (190°C).
- Lightly grease a 9×13-inch baking dish and set aside.
Step 2: Cook the Chicken and Vegetables
- Heat olive oil in a large skillet over medium-high heat.
- Add the chicken pieces and cook for 4–5 minutes until lightly browned but not fully cooked. Remove from the skillet and set aside.
- In the same skillet, add the bell peppers and onions. Sauté for 5–7 minutes until softened.
Step 3: Combine the Fajita Base
- Return the chicken to the skillet.
- Stir in the diced tomatoes, lime juice, and all the spices (chili powder, smoked paprika, cumin, garlic powder, onion powder, salt, and black pepper).
- Cook for an additional 3–4 minutes to combine flavors.
Step 4: Assemble the Casserole
- In a mixing bowl, combine the sour cream and cream cheese until smooth.
- Spread the cooked rice (if using) evenly across the bottom of the prepared baking dish.
- Pour the chicken and vegetable mixture over the rice.
- Spoon the sour cream and cream cheese mixture on top, spreading it evenly.
- Sprinkle shredded cheese over the top of the casserole.
Step 5: Bake the Casserole
- Cover the dish with aluminum foil and bake in the preheated oven for 20 minutes.
- Remove the foil and bake for an additional 10–15 minutes, or until the cheese is melted and bubbly.
Step 6: Serve and Enjoy
- Let the casserole rest for 5 minutes before serving.
- Garnish with fresh cilantro and serve with tortilla chips, warm tortillas, or a side salad.
Tips for Success
- Prep Ahead: Chop the vegetables and marinate the chicken the night before to save time.
- Make It Spicy: Add diced jalapeños or extra chili powder for more heat.
- Cheese Choices: Swap Mexican cheese blend with pepper jack for added spice.
Variations
- Low-Carb Option: Skip the rice and serve the casserole over cauliflower rice.
- Vegetarian Version: Substitute the chicken with black beans, corn, and mushrooms.
- Add Toppings: Top with diced avocado, pico de gallo, or a dollop of guacamole for extra flavor.
