How to Make Leftover Turkey Stuffing Casserole
This is a simple, homey bake that works because it is flexible. I make it when I want dinner to feel like comfort food, but I do not want to think too hard. The idea is easy: a creamy turkey layer, then stuffing on top, then bake until the edges bubble.
What you will need
- Cooked turkey, chopped or shredded (about 3 to 4 cups)
- Leftover stuffing (about 3 to 5 cups)
- Frozen or cooked veggies (1 to 2 cups, peas and carrots or mixed veggies are great)
- 1 can cream of mushroom or cream of chicken soup (or 1 and 1/2 cups homemade gravy)
- 1/2 cup milk or broth (more if you like it extra creamy)
- 1/2 cup sour cream or plain Greek yogurt (optional but so good)
- Salt and pepper
- Butter for dotting the top (1 to 2 tablespoons)
If you do not have stuffing left, you can absolutely make it. I have used this homemade stuffing from scratch with herbs when we ran out, and it made the whole casserole taste extra fresh.
Directions
1) Heat your oven to 375 F. Lightly grease a 9×13 baking dish.
2) In a big bowl, mix turkey, veggies, soup (or gravy), milk or broth, and sour cream if using. Season it. I usually do a few pinches of salt and a lot of pepper.
3) Spread that creamy turkey mixture into the baking dish.
4) Add stuffing on top. If your stuffing is dry, sprinkle a few tablespoons of broth over it. Dot the top with a little butter.
5) Bake 25 to 35 minutes, until hot all the way through and the top is browned. If the top starts to get too dark, loosely cover with foil for the last 10 minutes.
Let it sit 5 to 10 minutes before scooping. It thickens a bit as it rests, and it is easier to serve without turning into a sloppy pile. Not that I would complain if it did.
Also, if you love the whole chicken and stuffing vibe, you should check out this crock pot chicken and stuffing casserole sometime. It is a nice option when you want a similar comfort dinner without turning on the oven.
Variations & Tips
This is where you can really make it yours. Leftover Turkey Casserole with Stuffing is forgiving, which is probably why it has saved so many random weeknights at my house.
Make it cheesier: Sprinkle 1 to 2 cups shredded cheddar or mozzarella over the turkey layer before adding stuffing. Or add a little Parmesan on top for extra crunch.
Add cranberry: A few spoonfuls of cranberry sauce tucked into the turkey layer sounds weird until you try it. It adds sweet little pops that make the whole thing taste like a holiday plate.
Use gravy instead of soup: If you have leftover gravy, use it. The flavor feels more old school and less casserole aisle. Just thin it with broth or milk so it mixes easily.
Make it lighter: Use Greek yogurt instead of sour cream and use broth instead of milk. Still creamy, just not as heavy.
Boost the veggies: I toss in green beans, mushrooms, corn, or whatever is hanging around. If you are already thinking green beans, this green bean casserole with bacon is also a fun side on a cozy dinner night.
I will be honest, the first time I made this, I worried it would be bland. The trick is seasoning. Leftovers can be a little muted after sitting in the fridge, so taste your mixture before it goes in the pan. Add pepper, a pinch of garlic powder, or a tiny bit of poultry seasoning if it needs help.
“I made this after Thanksgiving and my kids asked for seconds, which never happens with leftovers. The stuffing top got perfectly crispy and it tasted even better the next day.”
If you are into different casseroles in general, I also really like this garlic parmesan chicken casserole with pasta for a weeknight switch up. Totally different flavors, same comforting payoff.
What to Serve with Leftover Turkey Casserole
This is a full meal kind of bake, so you do not need much. But I like adding something fresh or crisp so the plate does not feel all soft and creamy.
- Simple salad with a tangy vinaigrette, even just greens and cucumber
- Roasted broccoli or Brussels sprouts
- Cranberry sauce on the side if you love that sweet and savory thing
- Warm dinner rolls if you want maximum comfort
- Pickles or something acidic, sounds random but it cuts the richness
Sometimes I make a quick pan of roasted carrots while the casserole bakes. Easy, no stress. And if you want another cozy main idea for a different week, this Dollys chicken and stuffing casserole is one I have bookmarked because it hits that same comforting note.
How to Store Leftover Turkey Casserole
Storage is simple, but a couple small habits make it taste better later.
In the fridge: Let the casserole cool, then cover the dish tightly or transfer portions to containers. It keeps well for 3 to 4 days.
To reheat: The oven is best if you want the stuffing top to crisp back up. Heat at 350 F until hot. For a quick lunch, the microwave works fine. I just add a splash of broth or milk so it does not dry out.
In the freezer: You can freeze it, but stuffing can soften a bit after thawing. Still tasty though. Wrap the dish well, or freeze individual portions. Thaw overnight in the fridge, then reheat in the oven for the best texture.
How Long is Leftover Turkey Good For?
This is the part I take seriously, because nobody needs food poisoning as a holiday memory.
Cooked turkey is usually good for 3 to 4 days in the fridge if it was cooled and stored promptly. If it has been sitting out for a long time during dinner or a party, be more cautious. When in doubt, toss it. I know that feels painful, but it is not worth it.
If you want to stretch it longer, freeze turkey within that 3 to 4 day window. Frozen turkey is best within 2 to 3 months for good flavor, but it is safe longer if your freezer stays cold.
Common Questions
Can I make Leftover Turkey Casserole with Stuffing ahead of time?
Yes. Assemble it, cover, and refrigerate up to 24 hours. Add a few extra minutes of baking time since it is going in cold.
What if my stuffing is really dry?
Drizzle a little broth over the stuffing before baking. You can also mix a spoonful of melted butter into the stuffing to help it crisp without drying out.
Can I use mashed potatoes too?
You can. I have layered mashed potatoes under the turkey mix, then topped with stuffing. It is very comforting and very filling.
How do I know it is heated through?
The edges should be bubbling and the center should be hot. If you have a thermometer, aim for 165 F in the middle.
Can I make it without soup?
Absolutely. Use leftover gravy, or make a quick creamy sauce with butter, flour, broth, and a splash of milk. Keep it simple.
