Ingredients for Leftover Turkey Casserole

To create the perfect Leftover Turkey Casserole, you’ll need the following ingredients:
Essential Ingredients
- 2 cups cavatappi pasta uncooked, or another short tube pasta
- 2 cups leftover turkey chopped or shredded
- 21 ounces condensed cream of chicken soup (2 10.5-ounce cans)
- 12 ounces frozen peas (1 bag)
- 3/4 cup half and half
- 3/4 cup shredded mozzarella and provolone cheese divided between the filling and topping
- 1/2 teaspoon garlic powder
- 1/2 teaspoon onion powder
- 1/4 teaspoon black pepper
- 3/4 cup Italian style panko breadcrumbs
- 3 tablespoons salted butter melted
Optional Ingredients
- Fresh parsley chopped, for garnish
- Extra mozzarella for a golden, stretchy top
- Red pepper flakes a pinch, for gentle heat
How to Make the Casserole
Follow these steps to bring the casserole together:
- Boil the Pasta: Bring a large pot of salted water to a boil, add the cavatappi, and cook for 9-10 minutes until just tender. Drain well and set aside.
- Mix the Sauce: In a large bowl, whisk the condensed cream of chicken soup, half and half, garlic powder, onion powder, and black pepper until smooth, about 1 minute.
- Combine the Filling: Fold in the chopped turkey, frozen peas, drained pasta, and 1/2 cup of the cheese until everything is evenly coated.
- Top and Bake: Spread the mixture in a greased 9×13-inch baking dish. Toss the panko with the melted butter and the remaining 1/4 cup cheese, then sprinkle over the top and bake at 375°F for 25-30 minutes until bubbling and golden.

Variations and Customizations
One of the great things about this casserole is its versatility!
- Vegetable Additions: Stir in sautéed sliced mushrooms or chopped spinach for extra nutrition and color.
- Spicy Kick: Add a dash of hot sauce or a pinch of cayenne to the sauce for a little heat.
- Cheesy Upgrade: Swap the cheese blend for sharp cheddar, which adds a tangy bite.
- Make-Ahead Option: Assemble the casserole up to 24 hours in advance, refrigerate it, and allow 5-10 extra minutes of baking time when cooking it straight from the fridge.
