Thanksgiving Leftovers Casserole Tips

Can you use leftover mashed potatoes from Thanksgiving instead of cooking and mashing potatoes for this recipe?

This recipe is one of many great ways to use leftover mashed potatoes. Note that this recipe calls for adding cream cheese and sour cream to make mashed potatoes, so depending on how you made yours, you probably won’t need to add more. Reheat leftover potatoes and add a little bit of liquid—milk, cream or more sour cream—if needed to get them to spreading consistency.

How can you make Thanksgiving leftovers casserole your own?

Feel free to add any leftovers you have to this casserole. Between the potatoes and stuffing, this casserole is heavy on the starch—so try mixing vegetables, such as green beans, peas or Brussels sprouts into the mixture. You can also swap out the mashed potato topping for mashed sweet potatoes, if that’s what you served at your feast!

What can you serve with Thanksgiving leftovers casserole?

If you don’t add vegetables into your Thanksgiving leftovers casserole, be sure to serve this up with a veggie on the side to make a balanced meal. This can be any number of holiday sides, such as sprouts (or cranberry sauce!), or a fresh and crisp fall salad.
