The Ultimate Leftover Turkey Casserole That Will Change Your Life
The holiday feast is over. The last guest has gone home, and your fridge is now a tightly packed archive of every food group known to man. The initial joy of endless leftovers is starting to fade, and the thought of another turkey sandwich is, frankly, a little depressing.

It’s the recipe that will make you feel like a culinary genius, even when you’re still recovering from a food coma.

Step-by-Step Guide to Leftover Glory
This is less about cooking and more about strategic layering. You can do this with your eyes half-closed.
H3: The Assembly (The Easiest Part of Your Day)
- Preheat & Prep: Preheat your oven to 375°F (190°C). Grease your 9×13 inch baking dish.
- Create the Foundation: In a bowl, mix your leftover stuffing with about a cup of warm gravy or broth until it’s moistened but not soggy. Press this mixture evenly into the bottom of your prepared dish.
- The Turkey Layer: In your large mixing bowl, combine the shredded turkey, 1 ½ cups of gravy, and any leftover veggies you’re using. Stir it all together until the turkey is well-coated. Spread this savory mixture evenly over the stuffing layer.
- The Grand Potato Topping: Spoon the leftover mashed potatoes over the turkey layer. Use the back of your spatula to gently spread the potatoes all the way to the edges of the dish, creating a “seal.” Pro-tip: If your mashed potatoes are cold and stiff, warm them in the microwave for a minute to make them easier to spread.
- Get Fancy: Use the tines of a fork to create some decorative swirls or lines across the top of the potatoes. This isn’t just for looks; it creates little ridges that will get extra golden brown and delicious. Sprinkle with shredded cheese and/or paprika, if you’re feeling it.
H3: Bake and Devour
- Bake Until Bubbly: Place the casserole on a baking sheet to catch any potential drips. Bake for 30-40 minutes, until the casserole is heated through, the gravy is bubbling up the sides, and the mashed potato topping is beautifully golden brown.
- Rest and Serve: Let the casserole rest for about 10 minutes before serving. This will help it set up a bit, making it easier to scoop out those perfect, layered portions.

Common Mistakes to Avoid (For a Perfect Leftover Bake)
Don’t let these simple slip-ups stand in the way of your comfort food dreams.
- Dry Layers: The biggest crime against a leftover casserole is dryness. Do not be afraid to add more gravy or broth! Your stuffing should be moist, and your turkey should be generously coated in gravy. Dry leftovers make for a dry, sad casserole.
- A Leaky Potato Seal: If you don’t spread the mashed potato topping all the way to the edges of the dish, the gravy from the turkey layer will bubble up and over, making a mess of your beautiful topping (and your oven). Seal those edges!
- Using Cold, Stiff Potatoes: Trying to spread cold, hard mashed potatoes is a frustrating exercise that will just tear up your turkey layer. Gently warm the potatoes in the microwave or on the stove with a splash of milk to make them smooth and spreadable.
Variations & Customizations
This is your casserole; you make the rules.
- Sweet Potato Shepherd’s Pie: Swap the regular mashed potatoes for leftover sweet potato casserole on top. The sweet and savory combination is absolutely incredible.
- Add a Biscuit Topping: Don’t have leftover mashed potatoes? No problem. Skip the potato layer and top the turkey mixture with refrigerated biscuit dough. Bake according to the biscuit package directions for a pot-pie style casserole.
- Spicy Turkey Casserole: Add a kick to your turkey and gravy mixture with a few dashes of your favorite hot sauce, a pinch of cayenne pepper, or a can of diced green chiles.
FAQ: Your Leftover Casserole Questions, Answered

2. Can I freeze this casserole?
Yes! It freezes wonderfully. You can freeze it before or after baking. For best results, bake it first, let it cool completely, then cover it tightly and freeze for up to 3 months. Thaw it overnight in the fridge before reheating in the oven.
3. My stuffing is really dry. What should I do?
Just add more liquid! Mix it with some warm turkey broth or gravy until it reaches a moist, spreadable consistency before you press it into your casserole dish.
4. Can I make this with leftover chicken instead of turkey?
Absolutely! This recipe works perfectly with leftover roasted chicken.

Stir in a few tablespoons of warm milk, cream, or even a dollop of sour cream or butter to loosen them up before topping your casserole.

Nope! You could use a layer of leftover mac and cheese, cooked rice, or even just another layer of mashed potatoes if you prefer.
7. How do I reheat the casserole?
The best way is to cover it with foil and reheat it in a 350°F (175°C) oven for about 20-30 minutes, until it’s hot and bubbly. You can also reheat individual portions in the microwave.
