Mom's Best Mashed Potato Pie

Mom's 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,  this 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.

Today, this is still one of our favorite dishes.  Everyone loves this 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.

This makes a wonderful side dish for the holidays too!  Enjoy!

Here's are a few Tips:   To get a creamy mixture from the potatoes when mashed, use an immersion hand-stick blender or a hand mixer.  If you don't have one, we highly recommend using either one to blend the potatoes into a smooth and creamy texture. 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. When you get home from work, reheat in oven uncovered for 30 minutes, or until it's well heated through.
