Our Mom’s Best Mashed Potato Pie

Okay, our mom’s best-mashed potato pie is not low in calories. However, it’s so 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 are so light and creamy with a crispy crust on top! What’s not to love? 

It’s amazingly delicious! Our potato pie is very similar to a potato croquette but without frying!

This recipe makes a large casserole, and it is perfect to feed a crowd.  It pairs perfectly with our mom’s best chicken piccata.  And, reheats beautifully too!

Everyone loves Mom’s Best Mashed 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. Toss in some additional ingredients and mix until the mixture is creamy, then bake!

 

Cook’s Helpful Notes and Tips:

• To get a creamier mixture from mashed potatoes, use an immersion hand-stick blender or a hand mixer.  They work best. Then continue with the recipe.
• You can omit the ham inside and it becomes a “vegetarian” version.

• 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, and allow it to thaw on the counter for several hours.  When you get home from work, reheat in the oven uncovered for 30 minutes, or longer until it’s well heated through.

Ingredients for Mom’s Best Mashed Potato Pie

For mom’s best-mashed potato pie, you will need the following :

• 5 lbs. Idaho potatoes – peeled then chopped
• 1/4 pound sliced Ham – chopped
• 1 (16 ounces) Mozzarella – chopped ( you can use low-fat)
• 4 large whole eggs – lightly beaten
• 1 cup Pecorino Romano cheese- grated
• 1 cup Parmesan cheese – grated
• 1 cup of 1% low-fat milk
• 2 Tbsp. fresh Italian parsley, finely chopped
• 1 stick butter – salted (we used Smart Balance Butter)
• 1 cup plain bread crumbs or GF bread crumbs
• 1/2 tsp. fresh ground pepper
• NO salt

Directions to Make Best Mashed Potato Pie:

1.  Peel and chop potatoes. In a large pot of boiling water, add the potatoes and cook for about 25 to 35 minutes, or until the potatoes are softened.  Drain in a colander.  Place potatoes back into the pot.

2.  Add the butter and mash the potatoes until well-mashed.
Using an immersion hand-stick blender, or an electric hand mixer, beat the potatoes to a smooth and creamy texture for about 2 minutes.  

3. Stir in chopped mozzarella, milk, eggs, ham, and parsley.
Use a large spoon to mix well.  Add the grated cheese and fresh ground pepper.  Mix well again.

4. Use a 16-inch rectangular deep casserole pan, ceramic or stainless steel.  Butter the bottom and sides of the pan.  Scatter 1/2 cup of bread crumbs and shake the pan until the entire surface is covered with bread crumbs.

5.  Pour the mashed potato mixture and spread it evenly in the pan.  Scatter some chopped pieces of butter on top.  Scatter the remaining 1/2 cup of bread crumbs on top.

6.  Bake at 350 degrees.  Uncovered, for ONE hour, or until the top is golden brown. Cool for 10 minutes. Cut into square pieces and serve.

Serves 8 to 12

Storing, Reheating and Freezing

• Store this mashed potato pie in a sealed air-tight container and keep it chilled in the refrigerator. It will stay fresh for up to 3 days.
• Reheat any leftovers can be done either in the microwave, and it should be only a serving on a plate. If you need to reheat the entire casserole, then it’s best to reheat it in a preheated oven at 350 degrees and for 15 to 20 minutes, until it is heated through.
• To freeze, we recommend you bake this casserole first, then allow it to cool completely, cover with aluminum foil, and freeze. It will freeze well, and only up to one month.
