Key Ingredients for Your Leftover Casserole

The beauty of this casserole lies in its use of common Thanksgiving staples. Here’s a closer look at the stars of this post-holiday show:

• TURKEY: The undisputed star of Thanksgiving day, and it continues its reign in this casserole. Shredded or diced turkey works best, providing savory protein throughout the dish. Whether it’s white meat, dark meat, or a mix, it all tastes fantastic here.
• TURKEY GRAVY: Essential for keeping the turkey moist and infusing the entire casserole with rich, savory flavor. Don’t skimp on the gravy; it acts as a binder and a flavor enhancer, ensuring every layer is delicious. If you ran out of homemade, a good quality store-bought gravy works wonders.
• MASHED POTATOES: Because mashed potatoes are simply the best! They provide a creamy, comforting layer that ties everything together. Fluffy and well-seasoned mashed potatoes are ideal for this.
• SOUR CREAM: Leftover mashed potatoes can sometimes dry out in the fridge. Adding sour cream is a secret weapon to bring back their moisture and give them an extra creamy, slightly tangy texture that complements the other rich flavors. A little bit goes a long way in revitalizing your spuds.
• CORN: A classic Thanksgiving side, corn adds a welcome touch of sweetness and a pleasant textural contrast to the softer components of the casserole. You can use frozen, canned (drained), or even fresh corn kernels.
• STUFFING: It simply wouldn’t be a Thanksgiving casserole without a generous layer of stuffing. The herbaceous, bread-based goodness is fundamental to the overall taste and texture. If your stuffing is a bit dry, consider adding a splash of chicken or turkey broth before layering it.
• CHEDDAR CHEESE: Topping things off with some shredded cheddar cheese adds a delightful salty, savory, and gooey finish. It melts into a golden-brown crust that makes the casserole even more appealing. Feel free to use your favorite melty cheese!

How to Make This Delicious Thanksgiving Leftover Casserole

This recipe is designed for ease and minimal fuss, making it the perfect post-holiday cooking project. You’ll have a warm, hearty meal on the table in just over an hour.

Tips and Delicious Variations for Your Casserole

This recipe is incredibly versatile, allowing you to tailor it to your family’s preferences and whatever leftovers you have on hand. Don’t be afraid to get creative!

• Cranberry Twist: If you enjoy a touch of tartness, consider replacing some of the gravy with cranberry sauce or spooning a layer of cranberry sauce over the turkey layer for a sweet and tangy contrast. You can also dollop some on top of individual servings!
• Protein Alternatives: While turkey is traditional, this casserole is equally delicious with other proteins. You could easily substitute the turkey with leftover shredded chicken or diced ham, offering a different flavor profile that’s still wonderfully comforting.
• Cheese, Please!: Cheddar is a classic, but don’t limit yourself! Experiment with other fantastic melting cheeses like creamy gouda, mild Monterey Jack, sharp provolone, or a Colby Jack blend. Each will add its own unique character to the casserole.
• Vegetable Swaps: Not a fan of corn, or simply have other veggies to use up? This casserole welcomes variety! Instead of corn, try a layer of green beans, leftover green bean casserole, peas, or even roasted carrots. Each addition brings its own texture and flavor.
• Make it Ahead: To save time on a busy day, you can assemble the entire casserole (up to the point of adding cheese) and cover it tightly. Store it in the refrigerator for up to 24 hours. When ready to bake, add about 10-15 minutes to the covered baking time to ensure it heats through, then proceed with adding the cheese.
• Add Some Crunch: For extra texture, sprinkle some crushed potato chips, fried onions, or even extra toasted stuffing crumbs on top with the cheese during the last few minutes of baking.
• Spice it Up: A pinch of poultry seasoning, a dash of garlic powder, or a sprinkle of dried thyme mixed into the mashed potatoes or gravy can enhance the overall savory depth.

Frequently Asked Questions About This Casserole

Got questions? We’ve got answers to help you master your Thanksgiving leftover casserole!

CAN I USE CREAMED CORN INSTEAD OF REGULAR CORN?

Absolutely, yes! This recipe is incredibly adaptable. Creamed corn will add an even richer, sweeter, and creamier texture to your casserole, blending beautifully with the other ingredients. Feel free to swap it in for regular corn, or even try a mix of both if you like!

WHAT CAN I SERVE WITH THIS CASSEROLE?

This casserole is a complete meal in itself, packed with protein, carbs, and vegetables. It’s hearty and satisfying enough to be served on its own. However, if you’d like to complement it, a light, crisp green salad with a vinaigrette dressing would be a wonderful choice to add freshness and cut through the richness. A simple side of steamed green beans or roasted brussels sprouts could also work well if you want more veggies without adding too much heaviness.

CAN I STORE THIS CASSEROLE IN THE FRIDGE?

For sure! Once cooled, cover any leftover casserole tightly with plastic wrap or aluminum foil, or transfer it to an airtight container. You can safely store it in the fridge for 2-4 days, depending on how fresh your original Thanksgiving leftovers were. Always ensure leftovers are properly cooled before refrigerating. To reheat, simply microwave individual servings or warm the entire casserole in the oven at 350°F (175°C) until heated through.

CAN I FREEZE THIS CASSEROLE?

Yes, this casserole freezes beautifully! After baking and cooling completely, you can freeze individual portions or the entire casserole. Wrap it tightly in plastic wrap, then a layer of aluminum foil, and place it in a freezer-safe bag or container. It will keep well for up to 2-3 months. To reheat from frozen, you can bake it covered at 350°F (175°C) for an hour or more, then uncover and bake until bubbly and heated through, or thaw it in the fridge overnight before reheating.

IS THIS CASSEROLE GLUTEN-FREE?

As written, this recipe is not gluten-free due to the stuffing. However, you can easily make it gluten-free by using a certified gluten-free stuffing mix or by making your own gluten-free stuffing. Ensure your gravy is also gluten-free, as some store-bought varieties contain wheat. All other ingredients are typically naturally gluten-free.
