Ingredients

  • 1.5 lbs boneless, skinless chicken breasts, cut into 1-inch cubes
  • 2 tablespoons olive oil
  • 1 large red bell pepper, thinly sliced
  • 1 large green bell pepper, thinly sliced
  • 1 large yellow bell pepper, thinly sliced
  • 1 large onion, thinly sliced
  • 3 cloves garlic, minced
  • 1 (8 oz) block cream cheese, softened
  • 1/2 cup chicken broth
  • 1/2 cup sour cream (or Greek yogurt for a lighter option)
  • 2 cups shredded Mexican blend cheese, divided
  • 1 tablespoon chili powder
  • 2 teaspoons ground cumin
  • 1 teaspoon smoked paprika
  • 1 teaspoon dried oregano
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon onion powder
  • 1/4 teaspoon cayenne pepper (optional, for heat)
  • Salt and freshly ground black pepper to taste
  • Fresh cilantro, chopped, for garnish
  • Lime wedges, for serving

Instructions

  • Step 1: Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.
  • Step 2: In a large mixing bowl, combine the chicken cubes with chili powder, cumin, smoked paprika, dried oregano, garlic powder, onion powder, cayenne pepper (if using), salt, and black pepper. Toss until the chicken is evenly coated.
  • Step 3: Heat 1 tablespoon of olive oil in a large skillet over medium-high heat. Add the seasoned chicken and cook until browned on all sides and mostly cooked through, about 5-7 minutes. Remove chicken from the skillet and set aside.
  • Step 4: Add the remaining 1 tablespoon of olive oil to the same skillet. Add the sliced bell peppers and onion. Sauté for 5-7 minutes, until vegetables are tender-crisp. Add the minced garlic and cook for another minute until fragrant.
  • Step 5: Reduce the heat to low. Add the softened cream cheese and chicken broth to the skillet with the vegetables. Stir continuously until the cream cheese is fully melted and a smooth sauce forms. Stir in the sour cream until well combined.
  • Step 6: Return the cooked chicken to the skillet with the vegetable and cream cheese mixture. Stir to coat everything thoroughly.
  • Step 7: Transfer half of the chicken and vegetable mixture into the prepared baking dish. Sprinkle with 1 cup of shredded Mexican blend cheese. Top with the remaining chicken and vegetable mixture.
  • Step 8: Sprinkle the remaining 1 cup of shredded cheese over the top of the casserole.
  • Step 9: Bake for 20-25 minutes, or until the casserole is bubbly and the cheese is melted and lightly golden brown.
  • Step 10: Remove from oven, garnish with fresh cilantro, and serve immediately with lime wedges.

Recipe Variations

For a spicier kick, add a diced jalapeño along with the bell peppers, or increase the amount of cayenne pepper. You can also swap chicken for shrimp or thinly sliced beef for a different protein. To make it low-carb, consider serving it over cauliflower rice or as a lettuce wrap instead of traditional tortillas. For a vegetarian option, replace the chicken with black beans and corn, adjusting seasonings as needed. If you prefer a smoky flavor, a dash of liquid smoke or chipotle powder can be added to the seasoning mix.

Pro Tips for Success

Achieving perfectly tender chicken and vibrant vegetables is key. When sautéing your chicken, avoid overcrowding the pan to ensure it browns nicely rather than steams. Similarly, don't overcook your bell peppers; they should still have a slight bite for the best texture in the casserole. Using a sharp knife for chopping your vegetables makes prep work safer and more efficient. For a truly effortless meal, prepare your chicken and vegetable mixture ahead of time and store it in the refrigerator. When ready to bake, simply assemble in your baking dish and pop it into the oven. This casserole is also great for meal prep!

Storage and Reheating Instructions

Leftover Chicken Fajita Casserole can be stored in an airtight container in the refrigerator for up to 3-4 days. To reheat individual servings, you can use the microwave until heated through. For reheating a larger portion, cover the baking dish with foil and warm in an oven at 300°F (150°C) until hot. This casserole freezes beautifully! Allow it to cool completely, then transfer to a freezer-safe container or wrap tightly in plastic wrap and foil. It can be frozen for up to 3 months. Thaw overnight in the refrigerator before reheating in the oven or microwave.

What to Serve with Your Casserole

This hearty Chicken Fajita Casserole is a meal in itself, but it pairs wonderfully with a few simple sides. A refreshing green salad, a side of fluffy white or brown rice, or a bowl of seasoned black beans are all excellent choices. For an extra touch of Tex-Mex flair, consider serving it with a dollop of additional sour cream, fresh avocado slices or guacamole, and a sprinkle of extra cilantro.
