It’s a simple, comforting meal ideal for weeknight dinners and can be prepared ahead for convenience.

  • Total Time: 1 hour 10 minutes
  • Yield: 6-8 servings

Ingredients

Chicken

  • 10 boneless, skinless chicken thighs (about 2 lbs)

Vegetables

  • 1 red bell pepper, seeded and sliced into thin strips
  • 1 large onion, peeled and sliced into thin strips

Dairy & Cheese

  • 8 oz cream cheese, softened
  • 8 oz shredded cheddar cheese, divided

Seasonings

  • 1.5 tbsp fajita seasoning
  • Salt and pepper to taste (optional)

Instructions

  1. Bake the chicken: Preheat your oven to 350°F (175°C). Place the chicken thighs in a casserole dish, cover with foil, and bake for 30-35 minutes or until the internal temperature reaches 160°F. Once baked, let the chicken cool for a few minutes, then shred or chop into bite-sized pieces. Discard any excess liquid from the dish.
  2. Sauté the vegetables: While the chicken bakes, heat a frying pan over medium-low heat and coat with cooking spray. Add the sliced red bell pepper and onion. Cook, stirring occasionally for about 20-25 minutes, allowing the vegetables to caramelize and become soft. Stir every 5-10 minutes for even cooking. Set aside once done.
  3. Combine ingredients: In a large mixing bowl, blend the softened cream cheese, half of the shredded cheddar cheese, and the fajita seasoning. Stir in the shredded chicken along with the cooked peppers and onions until evenly combined.
  4. Assemble the casserole: Transfer the mixture back into the casserole dish used for baking the chicken. Smooth the top, then sprinkle the remaining shredded cheddar cheese evenly over the surface.
  5. Bake the casserole: Return the casserole to the oven and bake uncovered for 25-30 minutes until the casserole is hot, bubbly, and the cheese on top is melted and golden.

Notes

  • Make-Ahead Tip: Prepare the casserole up to the assembly step and refrigerate for up to two days. When ready to bake, allow extra time (30-40 minutes) to ensure it is heated through and the cheese topping is bubbly and golden.
  • Adjusting Seasonings: Fajita seasoning blends vary in salt content. After cooking the chicken, taste the mixture and adjust salt and pepper as needed for balanced flavor.
