Thanksgiving is my favorite food holiday of the year.   I like that it’s all about being thankful and getting together with friends and family.  There’s no gift giving or stressing over anything except the food.   Since I love food it isn’t really a stress for me.

I love using leftover mashed potatoes in this Mashed Potato Puff Casserole!

However, one thing I notice is that there are always plenty of leftovers on Thanksgiving.  While I don’t mind having a turkey sandwich with gravy for lunch the next day I have trouble using up all of the leftovers we always have.  That’s why I’ve started putting together a list of meals to make out of the leftovers.

This week Sunday Supper is sharing a bunch of leftover recipes!   I can’t wait to see them all and add to my already growing list.   I’m sharing a recipe for leftover mashed potatoes.   Even when it’s not a holiday I tend to make more mashed potatoes then I need.

My recipe this week is for Leftover Mashed Potato Puff Casserole.   I made a version of these a year or two ago after Thanksgiving but made them in individual servings.  While they were really good and I liked the individual size it’s so much easier making it in a casserole dish.

Basically all you need to do is take the leftover mashed potatoes and mix them up with eggs, cheese, sour cream, and spices.   It’s a great way to re-purpose potatoes because you probably already have all the ingredients in your house.  Plus you can add whatever cheese and whatever spices you want to tailor it to your own likes.

The casserole simply bakes in an oven and then when it comes out it’s great with a little bit of sour cream and chives.    I like it because the ends and top get crispy while the middle puffs up and tastes light and fluffy.  So if you have extra mashed potatoes make sure to try them in this awesome casserole!

  1. Individual minis or in one big casserole dish, this is a fantastic way to use mashed potatoes =) Garlic always adds an interesting note to blander potatoes, too. Thanks for the recipe =)
