Ingredients
  

Casserole Ingredients
  • 1 lb rotini pasta 450g
  • 1.5 lbs chicken breast 680g, diced into 1-inch pieces
  • 4 tbsp unsalted butter 56g
  • 1/4 cup all-purpose flour 30g
  • 2 cups whole milk 480ml
  • 1 cup heavy cream 240ml
  • 1.5 cups mozzarella cheese 170g, shredded
  • 1 cup sharp cheddar cheese 115g, shredded
  • 1/4 cup fresh parsley finely chopped

Equipment

  • 1 9x13 inch white ceramic baking dish
  • 1 Large Skillet
  • 1 Whisk

Method
 

Preparation
  1. Cook rotini in salted water for 2 minutes less than package directions. Drain and set aside.
  2. In a skillet, sear diced chicken in olive oil until golden brown. Remove and set aside.
Assembly
  1. Melt butter, whisk in flour, then slowly add milk and cream until thickened into a smooth white sauce.
  2. Toss pasta, chicken, and sauce together. Transfer to a white ceramic baking dish.
  3. Top with mozzarella and cheddar. Bake at 375°F (190°C) for 20-25 minutes until golden brown spots appear.

Notes

Underbake the pasta slightly so it finishes in the sauce.
Broil for 2 minutes at the end for extra golden spots.
