This turkey rice casserole turns leftover turkey into a creamy, cheesy dinner with long-grain rice, extra-sharp cheddar, and a buttery Parmesan crumb topping. It's an easy turkey and rice casserole made from scratch with no canned soup, and you can make it ahead.
Add minced garlic and pulse briefly to combine; set aside.
1 garlic clove
Make the Filling
Melt the remaining chilled butter in a Dutch oven over medium heat.
4 tablespoons unsalted butter
Add onion and cook until softened, about 8 to 10 minutes.
1/3 cup onion
Stir in rice and cook, stirring constantly, until rice is translucent, about 1 minute.
1¼ cups long grain white rice
Add chicken broth, half-and-half, and salt. Bring to a boil.
4 cups chicken broth, 1¼ cups half-and-half, 1 teaspoon salt
Reduce heat to medium-low and cook, stirring often, until the rice is tender, about 20 to 25 minutes. *Note: If you use brown rice the cooking time will be longer.
Remove from heat and stir in cheddar, cayenne, Parmesan, and chopped cooked turkey.
Bake until the sauce is bubbling around the edges and the top is golden brown, about 15 minutes.
Cool for 5 minutes before serving.
Make Ahead
The filling can be prepared, placed in the greased baking dish, covered with plastic wrap, and refrigerated for 1 day.
Refrigerate topping separately. Bring filling to room temperature before adding bread crumbs and baking as directed.
Notes
Substitutions
Whole milk can replace the half-and-half.
Swiss, Monterey Jack, or Gouda can replace the cheddar.
Leftover chicken works in place of the turkey.
Storage and Reheating
Room Temperature: Do not leave the casserole out longer than two hours. Cover any leftovers and refrigerate promptly.
Fridge: Store leftovers in an airtight container for three to four days.
Freezer: Wrap tightly and freeze for up to four months. Thaw overnight in the refrigerator before reheating. If you freeze it before baking, add the breadcrumb topping just before cooking.
Reheat: Reheat covered in a 350-degree oven until warmed through. Individual portions warm nicely in the microwave at medium power.
