What Can You Use In Thanksgiving Leftovers Casserole Recipes


Many people wonder how long is leftover turkey good for? You can keep it in the fridge for 3-4 days or for 2-3 months in the freezer. If you have a lot of leftover turkey meat, freezing it allows you to use it for many different recipes later.

The greatest about Thanksgiving leftovers casserole recipes is that you can combine the favorite tastes of your family and substitute any ingredient for what you already have. For example, if a recipe calls for green beans, you can use Brussel sprouts instead. Even if you do not have turkey meat, you can use chicken and it is certain that your casserole will be super delicious!
