Moms Best Mashed Potato Pie, known as Gatto di Patate, is basically a Neapolitan potato pie recipe made with simple ingredients such as mashed potatoes, eggs, mozzarella, parmigiana and pecorino cheeses, butter, milk and ham.  A delicious recipe for those who love a great potato pie!

Ok, Moms Best Potato Pie is not low in calories.  However, it’s sooooo delicious and creamy–who cares!


Baked with pieces of cured ham and melted mozzarella mixed with mashed potatoes in a pie form or as a casserole, your family and friends will be eating and going back for more!

The taste and texture of this baked potato pie is so light and creamy with a crispy crust on top!  Mmmm!  It is very similar to a potato croquette, but without the frying!


Omit the ham inside and it becomes a vegetarian version.

Everyone loves Moms Best Potato Pie!  Even the kids!  We usually make this “Gatto” for gatherings with family and friends and it goes very quickly!

Even on a smaller scale, it’s a great recipe to whip up as an easy dish using your leftover mashed potatoes from the night before.



Moms Best Potato Pie makes a wonderful side dish for the holidays too!

Your family will love our moms best potato pie.  It is such a delicious dish!  And I bet this casserole  will be one of the first things that will disappear from your Thanksgiving or Christmas buffet.  It’s a winner!!  Our recipe makes a large casserole, perfect to feed a crowd.

Try this recipe!  Today, this is still one of our favorite dishes and we hope it will be yours too!



Here’s are a few Tips: To get a creamier mixture from mashed potatoes, use an immersion hand-stick blender or a hand mixer.  They work the best.  Then continue with the recipe.  Also, you can divide the potato mixture into 2 smaller foil trays, bake them, then freeze the trays for future dinners.

When you need one, just take a tray out in the morning, allow it to defrost on the counter for several hours.  When you get home from work, reheat in oven uncovered for 30 minutes, or until it’s well heated through.

    Hi there! We have a similar recipe in my family on my mother's father's side. From what I understand, no one knows how to spell the name pronounced "cutdaw". At least thats how I've heard it pronounced growing up.We also don't know the origin. This recipe of yours is the closest I've seen to it. Ours is 2 large potatoes, cream cheese and 6 eggs with the bread crumb and parm cheese crust. I noticed the name of yours and it also looks like it might be the same. How are you pronouncing what yours is called? And the origin? Thank you so much!

      Hi Amy! I had to call my mom and ask her how this recipe came about because we had no clue either.
      First, the name is in the Neopolitan dialict and it's pronounced as "got- toe" and it was originally a name for the bridal cake, and then later the name was adapted to this dish made with potatoes, as Gatto di patate, because it resembled the bridal cake – "sheet of cake " with a Light yellow color inside and a smooth and creamy texture. And my grandmother Anna ( who I am named after) and my great grandmother both made this pie. So I know it's been around over a century. It's interesting how recipes come about and thank you for asking – now we all know a little more about the history of this recipe! Thanks again!!

      Absolutely! Cover the baking dish well will foil wrap, then chill in your fridge. The next day, remove from the refrigerator and allow it to sit on your counter for an hour or so to warm up a little before baking. Then follow directions for baking.

    Can this be made a day before even if it has raw eggs in it?
    Thank you

      Hi Margy! Yes, you can make it the day before, but we recommend to bake it too. Then you can reheat it the next day, and it will still be light and fluffy even after you reheat it.

        Also, my sister said, you can make it one day ahead, refrigerate and then bake it the next day. As long as you keep it refrigerated, it is totally fine.
