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)

Step-by-Step Instructions

Step 1: Preheat your oven to 375°F (190°C). Grease a 9×13 inch baking dish with cooking spray or butter.

Step 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.

Step 3: Transfer the mixture to the prepared baking dish, spreading it out in an even layer.

Step 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.

Step 5: Cover the dish with aluminum foil and bake for 30 minutes. Remove from oven and carefully remove the foil.

Step 6: Sprinkle the shredded cheddar and mozzarella cheeses evenly over the top. If using breadcrumbs, sprinkle them over the cheese.

Step 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.

Step 8: Let the casserole rest for 5-10 minutes before serving to allow the sauce to thicken slightly.

Expert Tips for Perfect Results

• 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.
• Creamy alternative: For a lighter version, substitute half-and-half or whole milk for the heavy cream.
• Extra veggies: Add carrots, bell peppers, or mushrooms for additional nutrition and flavor.
