- 2 tablespoons olive oil (or butter)
- 1 lb boneless, skinless chicken breasts or thighs, sliced into thin strips
- 1 medium onion, thinly sliced
- 2 bell peppers (red, yellow, or green), thinly sliced
- 3 cloves garlic, minced
- 1 packet fajita seasoning (or homemade blend: chili powder, cumin, paprika, garlic powder, onion powder, salt, and pepper)
- 1 cup shredded cheddar cheese (or Mexican cheese blend)
- Optional: 1/2 cup sour cream or cream cheese (for extra creaminess)
For Topping:
- 1 cup crushed tortilla chips (optional, for added crunch)
- Fresh cilantro, chopped (for garnish)
- Optional: Sliced jalapeños, guacamole, salsa, or sour cream
Step-by-Step Instructions
1. Preheat the Oven
- Preheat your oven to 375°F (190°C).
- Lightly grease a 9x13-inch baking dish or casserole dish for easy cleanup.
2. Cook the Chicken and Vegetables
- Heat the olive oil in a large skillet over medium-high heat. Add the chicken strips and season with half of the fajita seasoning. Cook for 5–7 minutes, stirring occasionally, until golden brown and cooked through. Remove the chicken from the skillet and set aside.
- In the same skillet, add the sliced onion and bell peppers. Sauté for 5–7 minutes, until softened and slightly caramelized.
- Stir in the minced garlic and remaining fajita seasoning. Cook for an additional 1 minute, until fragrant.
- Return the cooked chicken to the skillet and mix everything together.
3. Assemble the Casserole
- Transfer the chicken and vegetable mixture to the prepared baking dish and spread it out evenly.
- Optional: Dollop sour cream or cream cheese over the top for extra creaminess.
- Sprinkle the shredded cheese evenly over the mixture.
- Optional: Top with crushed tortilla chips for added crunch.
4. Bake
- Bake in the preheated oven for 20–25 minutes, or until the cheese is bubbly and golden brown.
- Optional: Broil for the last 2–3 minutes to achieve an extra golden crust (watch closely to avoid burning).
5. Serve and Enjoy
- Remove the casserole from the oven and let it cool for 5 minutes before serving.
- Optional: Garnish with fresh cilantro and serve with your favorite toppings, such as guacamole, salsa, or sour cream.
- Enjoy every bite of this zesty, cheesy, and indulgent Fajita Chicken Casserole Bake!
- Perfect as a standalone meal or paired with a side of rice, beans, or a fresh salad for a complete spread.
Tips for Success
- Use Fresh Ingredients: Fresh garlic, herbs, and high-quality cheese make a noticeable difference in flavor.
- Switch Proteins: Substitute chicken with beef, shrimp, or plant-based alternatives for variety.
- Add Veggies: Stir in diced tomatoes, corn, or black beans for extra nutrition and depth of flavor.
