Ingredients

Scale
  • 3 cups cooked chicken breast, shredded or diced (about 1 lb)
  • 2 cups broccoli florets, steamed or blanched
  • 1 cup sliced mushrooms (white or cremini, optional)
  • 1/2 medium red onion, finely diced
  • 4 oz cream cheese, softened
  • 3/4 cup plain Greek yogurt
  • 1/2 cup low sodium chicken broth
  • 1/4 cup mayonnaise
  • 1 tsp garlic powder
  • 1 tsp dried thyme or Italian seasoning
  • 1/2 tsp paprika (smoked preferred)
  • Salt and pepper to taste
  • 1 1/2 cups shredded mozzarella cheese
  • 1/4 cup grated parmesan cheese (optional)
  • Chopped fresh parsley for garnish (optional)

Instructions

  1. Preheat oven to 400°F (200°C). Shred or dice cooked chicken. Steam or blanch broccoli until just tender (3-4 minutes), slice mushrooms, and dice onion. Pat all veggies dry.
  2. Heat a nonstick skillet over medium heat. Add a splash of olive oil, then sauté onions and mushrooms for 3-4 minutes until soft. Set aside to cool slightly.
  3. In a blender or food processor, combine cream cheese, Greek yogurt, chicken broth, mayonnaise, garlic powder, thyme, paprika, salt, and pepper. Blend until smooth and creamy.
  4. In a large mixing bowl, add chicken, broccoli, sautéed mushrooms, and onion. Pour creamy sauce over and toss gently to coat. If mixture is too thick, add a splash of broth.
  5. Transfer mixture to a greased 9×13-inch casserole dish. Spread evenly. Sprinkle mozzarella cheese and parmesan over the top.
  6. Bake uncovered for 20-25 minutes, until cheese is bubbling and golden brown. If browning too quickly, tent loosely with foil for last 5 minutes.
  7. Let casserole rest for 5 minutes before serving. Garnish with fresh parsley if desired. Serve hot.

Notes

Drain veggies well to avoid a watery casserole. Blending the sauce ensures a silky texture. For dairy-free, use plant-based yogurt and cheese. Make ahead by assembling without cheese, refrigerate, then add cheese before baking. Leftovers keep well and taste even better the next day.
