  • 8 Tbsp. butter divided
  • 1 cups chopped yellow onion
  • 3 cloves garlic finely chopped
  • 1/3 cup all-purpose flour
  • 2 1/2 cups chicken broth
  • 1 1/2 cups milk
  • 3/4 cup chopped fresh herbs such as parsley, sage, and thyme, plus additional for garnish
  • ½ tsp. kosher salt plus additional to taste
  • 1/2 tsp. pepper
  • 6 cups cooked rice
  • 3 to 4 cups chopped cooked chicken
  • 2 cups breadcrumbs


  • Preheat oven to 400°F.
  • Melt 2 tablespoons butter in a Dutch oven over medium heat.
  • Add onion and garlic; cook, stirring occasionally, until softened, about 5 minutes.
  • Add another 4 tablespoons butter; let met.
  • Stir flour into butter and onions. Cook, stirring, 2 minutes.
  • Whisk in milk and broth until combined.
  • Cook, whisking often, until mixture comes to a simmer and has thickened, about 7 minutes.
  • Remove from heat. Stir in herbs, salt, and pepper.
  • Gently stir in rice and chicken. Taste for seasonings; add salt ¼ teaspoon at a time to reach desired flavor.
  • Transfer to an 11x7-inch casserole dish.
  • In a medium bowl, stir together breadcrumbs and remaining 2 tablespoons butter.
  • Sprinkle breadcrumbs over casserole. Bake until golden and bubbly, about 15 minutes.


  • Any type of cooked chicken will work in this recipe; you can use shredded rotisserie chicken from your grocer’s deli, or roast your own.
  • To roast your own, drizzle two chicken breasts with olive oil; sprinkle with salt and pepper, and bake at 375°F on a rimmed baking sheet until cooked through, 35 to 40 minutes.
  • Use any type of cooked rice you like; just be aware that some brown and wild rice blends contain extra seasoning and salt, so taste the casserole filling before adding more salt.
  • Customize the herb blend to suit your taste. I used a blend of ½ cup parsley, 3 tablespoons thyme, and 1 tablespoon sage.
  • Not a fan of breadcrumbs? Stir 2 cups crushed crackers with butter and use as a topping instead.
