You might want to roast turkey all year for this flavorful leftover cheesy turkey casserole.
Not only is this casserole easy to make, but it also works with any leftover cooked meat to create an incredibly tasty, comforting dish that will have everyone asking for seconds.

What’s to love about this leftover cheesy casserole?
Warm, comforting and simple to reheat, casseroles are a classic weeknight favorite. This recipe is adaptable and forgiving—you can use leftover turkey, chicken, ham, pork, lamb or sausage and still get excellent results.
It’s especially handy after Thanksgiving when you often have roasted turkey leftovers. Small bits of meat and trimmings are perfect for folding into a casserole for an easy second meal.

Thanksgiving leftovers
If your holiday tradition includes ham or another roast, use that meat instead—this casserole shines with many proteins. I’ve even made it with leftover lamb and it was a hit.
This version uses rice. If you prefer, substitute quick-cooking barley for a nuttier texture and extra nutrition. Quick-cook grains save time while still delivering great flavor.
It’s cheesy and satisfying—so much so that it’s been nicknamed “kickasserole” in our house. Don’t wait for leftovers: rotisserie chicken or turkey breast works well when you want a fast dinner.

- Cook the rice in 2 cups lightly salted water according to package directions (about 15–20 minutes) until tender; drain if necessary.
- Meanwhile, heat olive oil in a large cast-iron or nonstick skillet over medium heat. Add chopped onion, bay leaf and rosemary leaves (discard the twig) and sauté until the onion is translucent, about 3–4 minutes. Add garlic and cook another 30 seconds until fragrant.
- Add the chopped turkey and sliced mushrooms to the skillet and cook about 10 minutes. Remove and discard the bay leaf. Stir in the white wine, cooked rice and chopped parsley. Season with salt and freshly ground pepper to taste.
- Preheat the oven to 350°F (175°C). In a small bowl, combine the mozzarella, cheddar and Parmesan. Grease a casserole dish and spread half of the rice mixture in the dish. Sprinkle with half the cheese mixture, then add the remaining rice mixture and top with the remaining cheese.
- Bake for about 20 minutes until the cheese is melted and the casserole is heated through. Let rest 10 minutes before serving. Enjoy.
