For the Filling
- Turkey – A great way to utilize Thanksgiving leftovers; substitute with chicken if desired.
- Mashed Potatoes – Adds creaminess to the filling; use homemade or store-bought for convenience.

Step‑by‑Step Instructions for Leftover Thanksgiving Turkey Stuffed Shells
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While it’s heating, lightly grease a 1 1/2 quart baking dish with cooking spray or a touch of olive oil. This preparation will ensure that your Leftover Thanksgiving Turkey Stuffed Shells bake evenly and don’t stick to the pan.
Step 2: Cook the Pasta Shells
In a large pot of boiling salted water, cook the jumbo pasta shells for 8-9 minutes until they are al dente; this ensures the shells hold their shape when stuffed. Once cooked, carefully drain them in a colander and set aside to cool slightly. Be sure to keep them from sticking together as you prepare the filling.
Step 3: Prepare the Filling
In a large mixing bowl, combine the chopped turkey, warm mashed potatoes, diced onion, diced celery, and minced garlic. Mix until well combined and creamy. Add half of the shredded cheddar cheese, along with salt and pepper to taste. This filling for your Leftover Thanksgiving Turkey Stuffed Shells should be rich and flavorful, perfect for stuffing.
Step 4: Assemble the Shells
Spread 3/4 cup of gravy on the bottom of the prepared baking dish, creating a flavorful base. Using a medium cookie scoop, carefully fill each cooked pasta shell with the turkey mixture, placed side by side in the baking dish. This step is crucial as it ensures every shell is evenly loaded with that delicious filling.
Step 5: Top It Off
Once all the shells are filled, it’s time to build layers of flavor. Sprinkle the remaining stuffing over the filled shells, then drizzle the remaining gravy on top. Finish by scattering the rest of the shredded cheddar cheese evenly over everything. This will create a delightful crust as it bakes.
Step 6: Bake the Dish
Place the baking dish in the preheated oven and bake for 25-30 minutes. Look for the cheese to be melted and bubbly, and the dish to be heated through. The beautiful golden crust will signal that your Leftover Thanksgiving Turkey Stuffed Shells are ready to come out and be served.
