Ingredients
- 12 jumbo pasta shells
- 1 cup turkey, chopped
- 1 cup mashed potatoes
- 1 tablespoon celery, diced
- 2 tablespoons yellow onion, diced
- 1 clove garlic, minced
- 3 ounces cheddar cheese, shredded and divided
- 1 1/4 cups gravy
- 1 cup bread stuffing
- Salt, to taste
- Pepper, to taste
Instructions
- Step 1: Preheat the oven to 350°F. Lightly grease a 1 1/2-quart baking dish and set aside.
- Step 2: Boil the jumbo pasta shells for 8 to 9 minutes until al dente. Drain and set aside to cool slightly.
- Step 3: While the pasta cooks, warm the mashed potatoes until just heated through. In a medium bowl, combine the chopped turkey, warm mashed potatoes, diced onion, diced celery, minced garlic, and half of the shredded cheddar cheese. Season with salt and pepper to taste, then stir well to combine.
- Step 4: Spread 3/4 cup of gravy evenly on the bottom of the prepared baking dish. Using a medium cookie scoop or spoon, fill each pasta shell with the turkey mixture and place them in the baking dish. Scatter the bread stuffing over the stuffed shells, then drizzle with the remaining gravy. Sprinkle the remaining shredded cheddar cheese on top.
- Step 5: Bake uncovered at 350°F for 25 to 30 minutes, until heated through and cheese is melted. Optionally, garnish with fresh parsley, chives, or green onions before serving.
Tips & Variations

- Add a pinch of dried thyme or sage to the filling for extra holiday flavor.
- For a creamy texture, mix a little sour cream or cream cheese into the mashed potatoes before filling.
- If you prefer a crispy topping, sprinkle breadcrumbs mixed with melted butter over the cheese before baking.
