Ingredients
  

Ingredients
  • 2 lbs boneless, skinless chicken breasts, cubed
  • 4 medium potatoes, peeled and diced
  • 3 cups broccoli florets
  • 2 cups shredded cheddar cheese
  • 1 cup shredded mozzarella cheese
  • 1/2 cup grated Parmesan cheese
  • 1 cup heavy cream
  • 1/2 cup chicken broth
  • 1/4 cup all-purpose flour
  • 3 tablespoons butter
  • 2 cloves garlic, minced
  • 1 teaspoon paprika
  • 1/2 teaspoon black pepper
  • 1 teaspoon salt
  • 1/2 teaspoon onion powder

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 pot of boiling salted water, cook the diced potatoes for 8-10 minutes until just tender. Add the broccoli florets during the last 3 minutes of cooking. Drain well and set aside.
  3. In a large skillet, melt butter over medium heat. Add the cubed chicken and cook until no longer pink, about 6-8 minutes. Add minced garlic and cook for another minute until fragrant.
  4. Sprinkle flour over the chicken and stir to coat. Gradually pour in the chicken broth and heavy cream, stirring constantly until the sauce begins to thicken. Season with paprika, salt, pepper, and onion powder.
  5. Combine the cooked potatoes, broccoli, and chicken mixture in the prepared baking dish. Stir gently to distribute everything evenly.
  6. Sprinkle the shredded cheddar, mozzarella, and Parmesan cheeses evenly over the top of the casserole.
  7. Bake for 25-30 minutes, or until the cheese is golden brown and bubbly and the casserole is heated through.
  8. Let the casserole rest for 5-10 minutes before serving to allow the sauce to set slightly.

Notes

Parboiling potatoes ensures even cooking; cheese blend creates complex flavor; can assemble up to a day in advance; add extra vegetables like carrots or peas; pairs well with side salad
