Ingredients

Scale
  • 3 cups cooked chicken breast, shredded or chopped (rotisserie recommended)
  • 1 cup broccoli florets, lightly steamed
  • 1/2 cup diced red bell pepper
  • 8 oz cream cheese, softened
  • 1/2 cup sour cream
  • 1/2 cup chicken broth (low sodium preferred)
  • 1/4 cup grated Parmesan cheese
  • 1 tsp garlic powder
  • 1/2 tsp smoked paprika (optional)
  • 1/2 tsp onion powder
  • Salt and pepper, to taste
  • 1 cup shredded mozzarella cheese
  • 1 cup shredded sharp cheddar cheese
  • 2 tbsp almond flour
  • 2 tbsp butter, melted
  • Fresh parsley or chives, chopped for garnish (optional)

Instructions

  1. Preheat oven to 375°F (190°C). Lightly grease a 2-quart casserole dish with butter or nonstick spray.
  2. If using cooked chicken, shred or chop into bite-sized pieces. For raw chicken, season with salt and pepper, roast or poach until cooked through (about 20 minutes at 375°F), then shred.
  3. Steam broccoli florets for 2–3 minutes until just tender. Drain excess water.
  4. In a large bowl, combine chicken, broccoli, and diced bell pepper. Stir gently.
  5. In a separate bowl, whisk together cream cheese, sour cream, chicken broth, Parmesan, garlic powder, smoked paprika, onion powder, and salt and pepper until smooth.
  6. Pour the creamy sauce over the chicken and veggie mixture. Fold together until everything is coated. Add a splash more broth if mixture looks dry.
  7. Spoon the mixture into the prepared casserole dish and spread evenly.
  8. Mix shredded mozzarella and cheddar together, then sprinkle evenly over the casserole.
  9. In a small bowl, toss almond flour with melted butter. Sprinkle this mixture on top of the cheese.
  10. Bake uncovered for 25–30 minutes, until cheese is melted and bubbling with golden brown edges. Cover loosely with foil if the top browns too quickly.
  11. Remove from oven and let rest for 5–10 minutes before serving.
  12. Garnish with chopped parsley or chives and serve hot.

Notes

For best results, use room temperature dairy to avoid lumps in the sauce. Season each layer for maximum flavor. Don’t overcook veggies to prevent a watery casserole. Almond flour and butter create a crunchy topping; crushed pork rinds or extra Parmesan can be used as alternatives. Let the casserole rest before serving for a thicker, creamier texture. Leftovers reheat well and taste even better the next day.
