Ingredients

Scale

Chicken Mixture

  • 3 cups cooked shredded chicken (about 2 pounds uncooked boneless skinless chicken)
  • 3 bell peppers, thinly sliced, various colors
  • 1 small yellow onion, thinly sliced
  • 8 ounces cream cheese, softened
  • 2 tablespoons fajita seasoning (or 1 store bought packet)

Cheese

  • 2 cups shredded cheese, Colby Jack or Mexican blend

Garnish and Serving

  • Cilantro for garnish
  • Optional for serving: flour tortillas, rice, desired toppings

Instructions

  1. Combine Ingredients: In a large bowl, mix together the cooked shredded chicken, thinly sliced bell peppers, onion, softened cream cheese, fajita seasoning, and half of the shredded cheese until evenly combined.
  2. Prepare the Casserole Dish: Spread the chicken and vegetable mixture evenly into a 9×13 inch casserole dish, pressing down gently to create an even layer.
  3. Bake the Casserole: Place the casserole dish uncovered into a preheated oven at 350°F (175°C) and bake for 20 minutes to allow the flavors to meld and ingredients to cook through.
  4. Add Cheese Topping: Remove the casserole from the oven and sprinkle the remaining 1 cup of shredded cheese evenly over the top.
  5. Finish Baking: Return the casserole dish to the oven and bake for an additional 5 minutes, or until the cheese is fully melted and bubbly.
  6. Garnish and Serve: Remove from the oven, sprinkle with fresh cilantro if desired, and serve warm accompanied by flour tortillas, rice, and any preferred toppings.

Notes

  • You can use store-bought shredded chicken or roast your own to save time.
  • Adjust the fajita seasoning quantity to taste or use a homemade blend for a personalized flavor.
  • For a spicier kick, add sliced jalapeños or a dash of hot sauce.
  • Leftovers can be refrigerated for up to 3 days and reheated in the oven or microwave.
  • To make this dish gluten-free, serve with corn tortillas instead of flour tortillas.
