Sure, it's excellent smothered in gravy, but when you have a lot left, this gets old quick.
Enter this Keto Turkey Casserole. It is easy to make and a great way to mix up your leftovers.
Storage
Keep this casserole in the fridge for up to three days. You can freeze it for up to two months. I like to freeze casseroles in individual serving portions to make a quick meal easier.

what kind of turkey should it be dark or white meat
Wendy Polisi
Either is fine - dark meat is going to have more fat, but either work well.
Joyce M Friedman
Very tasty and we loved it a lot. The only problem is that the portion sizes are too small and we had to have another. Will be making this again.
