đź§ľ Ingredients (with Quantity):

🍗 Main Ingredients:

  • 3 cups cooked chicken breast, shredded or chopped
  • 1 red bell pepper, sliced
  • 1 green bell pepper, sliced
  • 1 yellow bell pepper, sliced
  • 1 medium onion, sliced
  • 1 tbsp olive oil
  • 1 tsp chili powder
  • 1 tsp cumin
  • 1/2 tsp paprika
  • 1/2 tsp garlic powder
  • 1/2 tsp onion powder
  • 1/2 tsp salt (adjust to taste)
  • 1/4 tsp black pepper
  • 1 cup sour cream
  • 4 oz cream cheese, softened
  • 1/2 cup salsa (your preferred heat level)
  • 2 cups shredded Mexican cheese blend

đź§‚ Optional Ingredients:

  • 1/2 tsp crushed red pepper flakes (for spice)
  • 1/2 cup cooked rice or cauliflower rice (for a fuller dish)
  • Fresh cilantro for garnish
  • Jalapeño slices (for topping)

👩‍🍳 Instructions:

  1. Preheat oven to 375°F (190°C) and grease a 9×13-inch baking dish.
  2. In a skillet, heat olive oil over medium-high heat. Sauté onions and bell peppers until soft (about 5–7 minutes).
  3. In a large mixing bowl, combine shredded chicken, sautéed veggies, sour cream, cream cheese, salsa, and all seasonings. Mix well until creamy and coated.
  4. Spread the mixture into the baking dish. Top with shredded cheese.
  5. Bake uncovered for 20–25 minutes, or until cheese is bubbly and slightly golden.
  6. Let cool for 5 minutes. Garnish with cilantro or jalapeños, if desired.
  7. Serve as-is, or scoop onto tortillas, rice, or lettuce wraps.

đź’ˇ Tips for Success:

  • Use rotisserie chicken for a time-saving shortcut.
  • Mix cheese into the casserole and on top for extra cheesiness.
  • Don’t overbake – just long enough to heat through and melt cheese.
  • Add drained black beans or corn for a heartier dish.

🌟 Recommendations:

  • Serve with lime wedges, avocado slices, or a dollop of guacamole.
  • Side dishes: Mexican rice, refried beans, or a crisp salad.
  • Make it a meal-prep favorite: refrigerate for up to 4 days or freeze in portions.
