Ingredients

Scale

Chicken

  • 2 pounds boneless, skinless chicken breasts, cut into thin strips

Vegetables

  • 1 large red bell pepper, sliced
  • 1 large green bell pepper, sliced
  • 1 large yellow bell pepper, sliced
  • 1 large onion, thinly sliced

Cheese

  • 1 ½ cups shredded cheddar cheese
  • 1 cup shredded Monterey Jack cheese

Spices and Extras

  • 2 tablespoons olive oil
  • 1 tablespoon chili powder
  • 1 teaspoon ground cumin
  • 1 teaspoon smoked paprika
  • ½ teaspoon garlic powder
  • ½ teaspoon onion powder
  • Salt and black pepper to taste

Instructions

  1. Prepare the Chicken and Vegetables: In a large bowl, mix the sliced chicken strips with olive oil, chili powder, ground cumin, smoked paprika, garlic powder, onion powder, salt, and black pepper. Toss until the chicken is thoroughly coated in the spices. Add the sliced bell peppers and onion to the bowl and mix well to combine all the ingredients.
  2. Assemble the Casserole: Preheat your oven to 375°F (190°C). Transfer the chicken and vegetable mixture into a greased 9×13-inch baking dish, spreading it out evenly.
  3. Add Cheese Topping: Sprinkle the shredded cheddar and Monterey Jack cheeses evenly over the top of the chicken and vegetables.
  4. Bake the Casserole: Place the baking dish in the preheated oven and bake for 30 to 35 minutes, or until the chicken is cooked through (internal temperature of 165°F) and the cheese is melted and lightly golden.
  5. Serve: Remove from oven and let the casserole rest for 5 minutes before serving. This dish pairs wonderfully with warm tortillas, rice, or a fresh green salad.

Notes

  • You can substitute chicken breasts with boneless skinless thighs for a juicier casserole.
  • Adjust the amount of chili powder to control the heat level to your preference.
  • For a dairy-free option, omit the cheese or substitute with vegan cheese alternatives.
  • Leftovers can be stored in the refrigerator for up to 3 days and reheated in the oven or microwave.
  • Add a squeeze of fresh lime juice and chopped cilantro on top before serving for extra zest and freshness.
