Ingredients
  

Ingredients
  • 2 lbs boneless, skinless chicken breasts, cubed
  • 4 medium potatoes, peeled and diced
  • 3 cups fresh broccoli florets
  • 1 can (10.5 oz) cream of chicken soup
  • 1 cup sour cream
  • 1 cup shredded cheddar cheese
  • 1/2 cup shredded mozzarella cheese
  • 1/2 cup milk
  • 1 small onion, diced
  • 2 cloves garlic, minced
  • 1 tsp paprika
  • 1/2 tsp black pepper
  • 1/2 tsp salt
  • 1/4 cup breadcrumbs (optional, for topping)

Method
 

Instructions
  1. Preheat your oven to 375°F (190°C). Cube the chicken breasts, dice the potatoes into 1-inch pieces, and chop the broccoli into bite-sized florets. Dice the onion and mince the garlic.
  2. In a large mixing bowl, combine the cream of chicken soup, sour cream, milk, minced garlic, paprika, salt, and pepper. Whisk until smooth and well combined.
  3. Add the cubed chicken, diced potatoes, broccoli florets, and diced onion to the sauce mixture. Stir gently until all ingredients are evenly coated with the creamy sauce.
  4. Pour the mixture into a 9x13 inch baking dish, spreading it evenly. If using breadcrumbs, sprinkle them over the top for extra crunch.
  5. Cover the baking dish with aluminum foil and bake for 40 minutes. Remove the foil, sprinkle the shredded cheeses evenly over the top, and bake uncovered for another 15-20 minutes, or until the cheese is bubbly and golden brown.
  6. Let the casserole rest for 5-10 minutes before serving. This allows the sauce to thicken slightly and makes serving easier.

Notes

Prep ahead by chopping vegetables and chicken the night before. Customize with additional vegetables like carrots or peas. The casserole can be assembled and frozen before baking for future meals.
