Chicken Fajita Casserole brings together the bold flavors of fajitas with the creamy comfort of a baked casserole. Loaded with spiced chicken, colorful peppers, onions, and gooey cheese, it’s the perfect one-dish meal.

Ingredients

  • Boneless Skinless Chicken Breasts: 1½ pounds – lean protein base, cut into thin strips.
  • Bell Peppers (mixed colors): 3 medium – add sweetness, color, and crunch.
  • Yellow Onion: 1 large – brings savory depth and caramelized flavor.
  • Olive Oil: 2 tablespoons – used for sautéing the chicken and veggies.
  • Fajita Seasoning: 2 tablespoons – classic spice blend for that signature kick.
  • Garlic Powder: 1 teaspoon – enhances the savory notes.
  • Cream Cheese: 4 ounces – adds creaminess and helps bind the casserole.
  • Sour Cream: ½ cup – tangy richness that balances the heat.
  • Shredded Monterey Jack Cheese: 1 cup – melts beautifully with a mild, creamy flavor.
  • Shredded Cheddar Cheese: 1 cup – adds sharpness and golden color.
  • Salt & Pepper: to taste – essential for seasoning layers.
  • Fresh Cilantro: for garnish – adds a pop of freshness at the end.

Instructions

  1. Preheat Your Equipment: Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish and set aside.
  2. Combine Ingredients: In a skillet over medium heat, warm olive oil and sauté sliced bell peppers and onions until softened, about 5–6 minutes. Add chicken strips and cook until no longer pink, about 7–8 minutes. Season with fajita seasoning, garlic powder, salt, and pepper.
  3. Prepare Your Cooking Vessel: In a bowl, mix cream cheese and sour cream until smooth. Add half of the shredded cheese blend and stir in the chicken and veggie mixture until everything is evenly coated.
  4. Assemble the Dish: Pour the mixture into your prepared baking dish and spread it evenly. Top with remaining cheese.
  5. Cook to Perfection: Bake uncovered for 20–25 minutes until cheese is bubbly and golden brown.
  6. Finishing Touches: Let the casserole rest for 5 minutes, then garnish with chopped fresh cilantro.
  7. Serve and Enjoy: Serve hot with warm tortillas, rice, or a fresh salad for a complete meal.

Notes

  • Use freshly shredded cheese for better melting.
  • Let the casserole rest before serving so it sets nicely.
  • Add lime juice before serving for a burst of brightness.
  • Freeze in individual portions for quick lunches.
