Ingredients
  

Ingredients
  • 2 lbs boneless, skinless chicken breasts, cubed
  • 4 medium potatoes, peeled and diced
  • 3 cups broccoli florets
  • 1 medium onion, diced
  • 3 cloves garlic, minced
  • 2 cups shredded cheddar cheese
  • 1 cup shredded mozzarella cheese
  • 1 cup heavy cream
  • 1/2 cup chicken broth
  • 2 tbsp olive oil
  • 1 tsp paprika
  • 1 tsp dried thyme
  • Salt and pepper to taste
  • 1/4 cup breadcrumbs (optional, for topping)

Method
 

Instructions
  1. Preheat your oven to 375°F (190°C). Grease a 9x13 inch baking dish with cooking spray or butter.
  2. In a large bowl, combine the cubed chicken, diced potatoes, broccoli florets, onion, and garlic. Drizzle with olive oil and season with paprika, thyme, salt, and pepper. Toss to coat evenly.
  3. Transfer the mixture to the prepared baking dish, spreading it out in an even layer.
  4. In a separate bowl, whisk together the heavy cream and chicken broth. Pour this mixture evenly over the chicken and vegetables in the baking dish.
  5. Cover the dish with aluminum foil and bake for 30 minutes. Remove from oven and carefully remove the foil.
  6. Sprinkle the shredded cheddar and mozzarella cheeses evenly over the top. If using breadcrumbs, sprinkle them over the cheese.
  7. Return to the oven, uncovered, and bake for an additional 15-20 minutes, or until the cheese is melted and bubbly, and the potatoes are tender when pierced with a fork.
  8. Let the casserole rest for 5-10 minutes before serving to allow the sauce to thicken slightly.

Notes

Prep ahead: Chop all vegetables and chicken the night before to make assembly quick and easy. Even cooking: Cut potatoes into uniform 1-inch cubes to ensure they cook at the same rate as the chicken. Cheese variations: Feel free to experiment with different cheese combinations like Monterey Jack, Colby, or Gouda.
