Ritz Cracker Chicken Casserole

Gather the ingredients. Position a rack in the center of the oven and heat to 325 F. Lightly grease a 2-quart casserole dish.

In a large bowl, combine 1 (10 3/4-ounce) can condensed cream of chicken or cream of mushroom soup, 1 (8-ounce) container sour cream (about 1 cup), 1/2 cup low-sodium or unsalted chicken broth, 5 cups diced cooked boneless chicken breasts (about 1 1/2 pounds), 1/2 teaspoon fine salt, 1/2 teaspoon freshly ground black pepper, and 1/3 cup thinly sliced scallions, if using.

Crumble 30 Ritz crackers (about 1 sleeve, 3.5 ounces) into the bottom of the prepared casserole dish.

Drizzle 4 tablespoons unsalted butter (melted) over the crackers.

Spoon the chicken mixture evenly over the Ritz cracker layer.

Crush the remaining 1 sleeve of crackers and toss them in a bowl with the remaining half of the melted butter.

Sprinkle the buttered cracker crumbs over the chicken mixture.

Bake the casserole until hot and bubbly, 30 to 40 minutes. Let cool slightly before serving.
