Description

Fajita Chicken Casserole is a cheesy, oven-baked dish that combines juicy chicken, sautéed peppers and onions, and Tex-Mex flavors in one easy meal. It’s hearty, flavorful, and perfect for weeknight dinners with minimal prep.


Ingredients

  • 1 1/2 lbs boneless, skinless chicken breasts or thighs, cut into strips
  • 3 bell peppers (red, green, or yellow), sliced
  • 1 red onion, sliced
  • 2 tbsp olive oil
  • 2 tbsp taco or fajita seasoning
  • 4 oz cream cheese, softened
  • 1/2 cup sour cream
  • 1 tsp garlic powder
  • 1/2 tsp salt
  • 1/2 tsp black pepper
  • 1 1/2 cups shredded cheddar or Mexican blend cheese
  • 2 tbsp fresh cilantro, chopped (optional, for garnish)

Instructions

  1. Preheat oven to 375°F (190°C) and lightly grease a 9×13-inch casserole dish.
  2. In a bowl, toss chicken, bell peppers, and onions with olive oil and fajita seasoning.
  3. Spread mixture evenly into the prepared casserole dish.
  4. In another bowl, mix cream cheese, sour cream, garlic powder, salt, and pepper until smooth.
  5. Dollop cream cheese mixture over chicken and veggies, then spread gently.
  6. Sprinkle shredded cheese evenly over the top.
  7. Bake uncovered for 30–35 minutes, until chicken is cooked through, veggies are tender, and cheese is bubbly and golden.
  8. Let rest a few minutes before serving. Garnish with fresh cilantro if desired.

Notes

  • Add black beans or cooked rice to make it more filling.
  • For a low-carb option, serve over cauliflower rice or eat as-is.
  • Add jalapeños or hot sauce to the cream cheese mix for extra spice.
  • Top with crushed tortilla chips for crunch before serving.
