How to Make Chicken Au Gratin Casserole

Melt 4 tablespoons of butter in a large oven-safe casserole dish over medium heat. Add 1.5 lbs boneless, skinless chicken breasts and brown on both sides.
Pour in 1/2 cup dry white wine and 1 cup chicken broth. Add 1 tablespoon fresh tarragon, 2 cloves (minced), 1/2 medium onion (chopped), 2 cloves garlic (minced), 1 teaspoon salt, and 1/2 teaspoon black pepper.
Bring to a boil over high heat.
Reduce heat to low, cover, and simmer for 20-25 minutes, or until chicken is cooked through and tender.
While the chicken simmers, cook 1 lb tortiglioni pasta according to package directions. Add 1 cup broccoli florets to the pasta water during the last 5 minutes of cooking.
Drain the pasta and broccoli and set aside.
Remove the chicken from the casserole and cut into 1-inch dices. Keep warm.
In a separate bowl, whisk together the remaining 4 tablespoons of butter and 1/4 cup all-purpose flour until smooth.
Gradually whisk the butter-flour mixture into the remaining juices in the casserole, stirring constantly until thickened.
Remove from heat and gently stir in the cooked tortiglioni, broccoli, and diced chicken.
Pour the mixture into the prepared oven-safe dish. Top with 2 cups shredded Canadian Havarti cheese and 1/2 cup breadcrumbs.
Bake in a preheated oven at 350°F (175°C) for 8-10 minutes, or until golden brown and bubbly.
Let stand for 5 minutes before serving hot.
