Ingredients
  

Ingredients
  • 2 lbs boneless, skinless chicken breasts, cubed
  • 4 medium potatoes, peeled and diced
  • 3 cups fresh broccoli florets
  • 1 large onion, chopped
  • 3 cloves garlic, minced
  • 2 cups shredded cheddar cheese
  • 1 cup shredded mozzarella cheese
  • 1 cup heavy cream
  • 1/2 cup chicken broth
  • 2 tablespoons olive oil
  • 1 teaspoon paprika
  • 1 teaspoon dried thyme
  • Salt and black pepper to taste
  • 1/4 cup grated Parmesan cheese
  • 2 tablespoons butter

Method
 

Instructions
  1. Preheat your oven to 375°F (190°C). Grease a 9x13 inch baking dish with butter or cooking spray.
  2. In a large skillet, heat olive oil over medium-high heat. Add the cubed chicken and cook until golden brown, about 5-7 minutes. Season with salt, pepper, and paprika during cooking.
  3. Add chopped onion and minced garlic to the skillet. Cook for another 3-4 minutes until the onions become translucent and fragrant.
  4. In a large mixing bowl, combine the cooked chicken mixture, diced potatoes, and broccoli florets. Toss everything together to distribute evenly.
  5. Pour the chicken broth and heavy cream over the mixture. Add dried thyme and stir until everything is well coated.
  6. Transfer the mixture to the prepared baking dish. Spread it evenly and top with cheddar and mozzarella cheeses.
  7. Sprinkle Parmesan cheese over the top and dot with small pieces of butter.
  8. Cover with foil and bake for 30 minutes. Remove the foil and bake for another 15-20 minutes until the cheese is bubbly and golden brown, and the potatoes are tender when pierced with a fork.
  9. Let the casserole rest for 5-10 minutes before serving to allow the flavors to meld together.

Notes

Cut potatoes into uniform pieces for even cooking. Can use frozen broccoli florets (thaw and pat dry first). Perfect for meal prep and reheats beautifully. Can be assembled a day ahead and refrigerated before baking.
