FAQs & Tips

Do you have to use all the layers?

Nope! Use whatever leftovers you have. For example, if you do not have greens, omit them. Or if you have mac and cheese…add it in! 

Do you add seasonings?

Since these are leftovers, the food should already be seasoned. If you find that is not that case, the seasonings I suggest adding are salt, pepper, thyme, garlic powder, and onion powder. 

How do you store leftovers?

Store leftover crockpot leftover Thanksgiving holiday casserole in the refrigerator for up to 4 days. 

What size slow cooker did you use?

I use a  6-quart slow cooker or Instant Pot for this recipe.
