Ingredients Method Notes

Ingredients
  

  • 2 cups cooked chicken breast, chopped
  • 3 medium potatoes, peeled and diced
  • 2 cups broccoli florets, chopped small
  • 1.5 cups shredded cheddar cheese
  • 1/2 cup sour cream
  • 1/4 cup mayonnaise
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • Salt and pepper to taste
  • 2 tablespoons olive oil
  • Fresh parsley or green onions optional, for garnish

Method
 

  1. Preheat the oven to 400°F (200°C). Peel and dice potatoes, then toss with olive oil, garlic powder, onion powder, salt, and pepper. Roast for 20–25 minutes until golden and tender. Steam or blanch broccoli for 3–4 minutes until crisp-tender.
  2. In a large mixing bowl, combine cooked chicken, roasted potatoes, and broccoli. Add sour cream, mayonnaise, and half of the shredded cheddar cheese. Mix thoroughly.
  3. Spread the mixture evenly in a greased 9×13-inch baking dish. Top with the remaining cheddar cheese.
  4. Bake at 375°F (190°C) for 20–25 minutes, or until the cheese is melted, bubbly, and lightly golden.
  5. Let the casserole rest for 5 minutes before serving. Garnish with parsley or green onions.

Notes

For extra creaminess, add 2–3 tablespoons of cream cheese to the mixture. You can also substitute sweet potatoes or cauliflower for a fun twist.
