Mashed Potato Cakes

Growing up, my Mom never let leftovers go to waste. Most times she would put yesterday’s mashed potatoes in a pie plate, dot the top with butter, and heat it up in the oven until the top was golden and crusty.

Old Fashioned Potato Cakes, however, were always my favorite. Mom would take chilled leftover mashed potatoes, mix them up with flour and eggs, and then fry them in oil in a hot cast iron skillet. Hmm…hmm…good!

I took my Mom’s original basic recipe and added in cheddar cheese and ham. Then to kick it up a notch even further, I added spicy jalapeño pepper to my Tex-Mex inspired mashed potato cake recipe.

So simple and so easy, you’ll find yourself regularly making extra mashed potatoes just so you’ll have leftovers for potato cakes!

Instructions

  1. Place chilled leftover mashed potatoes in a large bowl. Stir in a lightly beaten egg and the flour and season with salt and black pepper.
  2. Gently fold in the jalapeño pepper, onion, cheese, and diced ham (or bacon).
  3. Heat a large non-stick skillet or griddle over medium high heat, then add the butter to the pan and let it melt. (You can also use canola oil.)
  4. Cooking in batches, drop spoonfuls of the potato mixture into the pan and then flatten them slightly until they are about a half inch thick.
  5. Cook for three minutes on each side or until they are golden brown and crispy.
  6. Drain on paper towels and continue with the remaining potato mixture.

Recipe variation

For loaded mashed potato cakes, replace the ham with bacon bits and replace the diced onion with sliced green onions. To serve, garnish with sour cream and more sliced green onions.

How long can you store mashed potatoes?

You should use leftover mashed potatoes within 3 to 5 days after storing them in the refrigerator. You’ll want to keep that little fact in mind if you plan to use your leftovers for today’s recipe.

Can you freeze potato cakes?

Potato cakes can be frozen after cooking. First, let them cool completely, then place on a parchment paper lined baking sheet. Place the baking sheet uncovered in the freezer for 1 to 2 hours to flash freeze the potato cakes. Remove them from the pan, then store in freezer bags for up to 3 months.

How do you reheat potato cakes from frozen?

Let the potato cakes thaw for about 15 minutes, then reheat them on a baking sheet in a 350 degree oven for 15 minutes.

  • Oven Roasted Red Potatoes — Seasoned with pantry spices like rosemary, thyme, and garlic, these crispy potatoes are finished at the end with a drizzle of quality aged balsamic vinegar. 
  • Grilled French Fries with Spicy Ketchup — These delicious hand-cut French fries get nice and crispy on the outside and stay fluffy on the inside without using a deep fryer.
  • Ham and Cheese Potato Bites — Stuffed with chopped ham and a surprising secret ingredient (crushed pineapple!), these little twice-baked potatoes make an impressive party appetizer.
  • Rainbow Lime Potato Salad — A pretty and tasty side dish for Spring, this potato salad gets a little extra zing from fresh lime juice and zest!
  • Asiago Potato Stacks — These individual potato stacks work well as appetizers or even as a side for a special meal.
