Ingredients
  

Ingredients
  • 2 lbs boneless, skinless chicken breasts, cubed
  • 4 medium potatoes, peeled and diced
  • 3 cups broccoli florets
  • 1 cup shredded cheddar cheese
  • 1 cup shredded mozzarella cheese
  • 1/2 cup grated Parmesan cheese
  • 1 cup heavy cream
  • 1/2 cup chicken broth
  • 1 tsp garlic powder
  • 1 tsp onion powder
  • 1 tsp dried thyme
  • Salt and pepper to taste
  • 2 tbsp olive oil

Method
 

Instructions
  1. Preheat your oven to 375°F (190°C). Cut the chicken into 1-inch cubes, peel and dice the potatoes into similar-sized pieces, and separate the broccoli into florets.
  2. In a large mixing bowl, combine the chicken, potatoes, and broccoli. Drizzle with olive oil and season with garlic powder, onion powder, dried thyme, salt, and pepper. Toss everything together until evenly coated with the seasonings.
  3. In a separate bowl, whisk together the heavy cream and chicken broth to create the creamy sauce.
  4. Transfer the seasoned chicken and vegetables to a 9x13 inch baking dish. Pour the cream mixture evenly over the top, making sure it distributes throughout.
  5. Sprinkle the shredded cheddar, mozzarella, and Parmesan cheeses evenly over the top.
  6. Cover the baking dish with foil and bake for 30 minutes. Remove the foil and continue baking for another 15-20 minutes, or until the cheese is golden brown and bubbly, and the potatoes are tender when pierced with a fork.

Notes

Make sure all ingredients are cut to similar sizes for uniform cooking. Use a large enough baking dish to allow proper heat circulation. Let the casserole rest for 5-10 minutes after baking for easier serving. Can be assembled up to a day in advance and refrigerated until ready to bake.
