How to Make Thanksgiving Leftover Casserole
Step 1: Preheat your oven to 350°F (175°C). This initial step is crucial because a well-heated oven helps your casserole cook evenly.
Step 2: In a large mixing bowl, combine the shredded turkey, stuffing, mashed potatoes, green beans, and the optional bacon. Mix well until all ingredients are evenly distributed. This is your base, so ensure each bite will be packed with flavor.
Step 3: Grease a 9×13-inch baking dish with some cooking spray or a light layer of butter. This will prevent sticking and make for easier clean-up later.
Step 4: Spread half of your mixture into the bottom of the baking dish, pressing it down gently. This layer acts as the foundation for your casserole.
Step 5: Pour the turkey gravy over the first layer. The gravy will help keep all the components moist and flavorful. If you’re feeling adventurous, drizzle in some cranberry sauce here. It adds a delightful sweetness that balances savory notes.
Step 6: Next, sprinkle half of the shredded cheese over the gravy layer.
Step 7: Now, take the remaining mixture and layer it on top of the cheese. Press it down gently once more.
Step 8: Finish by topping with the rest of the cheese and any remaining turkey gravy or cranberry sauce. The cheese will create a beautiful golden crust, adding an irresistible cheesy layer.
Step 9: Cover the dish with aluminum foil and bake for 20 minutes. After 20 minutes, remove the foil and bake for an additional 10 minutes. This will give the cheese time to melt and bubble deliciously.
Step 10: Once baked, take it out of the oven and let it cool for a few minutes before serving. Garnish with fresh herbs if desired for a touch of color and flavor.
Healthier Alternatives
If you’re looking to make this casserole a bit healthier, consider these swaps:
- Swap regular mashed potatoes for cauliflower mash for a lower-carb alternative.
- Use whole grain or gluten-free stuffing to fit dietary preferences.
- For those on a vegan diet, substitute turkey with jackfruit or mushrooms, and use cheese alternatives made from nuts.
- Opt for low-fat cheese or omit it entirely for a lighter version.
Serving Suggestions
Elevate your casserole presentation by serving it in individual ramekins or bowls. Pair it with a crisp salad tossed in a light vinaigrette to balance the richness of the casserole. For a flavorful beverage, consider a sparkling apple cider or a refreshing herbal tea.

Common Mistakes to Avoid
- Not allowing the casserole to cool slightly before serving can lead to a messy serving. Patience pays off!
- Skipping the step of greasing the baking dish can result in a dish that is challenging to serve.
- Overbaking can make your casserole dry. Keep an eye on it and pull it out once golden!
- Forgetting to layer the gravy and cheese properly will result in uneven distributions of flavor.
Storage Tips
Refrigerate leftovers in an airtight container for up to 3 to 4 days. If you want to freeze the casserole, it can stay in a freezer-safe container for up to 3 months. To reheat, bake at 350°F until heated through, about 20-25 minutes if frozen; you may need to add a splash of broth or water to keep it moist.
Frequently Asked Questions
Can I use other types of meat besides turkey?
Absolutely! Feel free to substitute turkey with chicken or even beef. Just adjust the flavors to match your meat of choice for the best results.
How can I adjust the recipe for a smaller group?
You can easily half the recipe by using a smaller baking dish, like an 8×8-inch size, and adjust cooking time accordingly.
Can I prep this casserole ahead of time?
Yes! You can assemble the casserole a day in advance and refrigerate it until you’re ready to bake. Just increase the baking time by about 10-15 minutes if cooking straight from the fridge.
What if I don’t have leftover stuffing?
If you don’t have stuffing, bread cubes mixed with seasonings, or even rice can work as a great base instead.
Is it possible to make this casserole vegetarian?
Yes! Swap the turkey for extra vegetables, mushrooms, or plan-based protein, and use vegetable stock and cheese substitutes for a delicious vegetarian version.
