Mashed Potato Cakes always remind me of my mom. These little balls of soft, creamy, buttery potatoes were one of my favorite things she’d create out of lowly leftovers. Whenever possible, I make extra mashed potatoes just so I can have leftovers and enjoy these really delicious potato cakes.

Mashed Potato Cakes
This super side dish may have started out as more of an idea than a recipe. It’s a simple and basic mixture made with simple ingredients and leftover mashed potatoes. It has a bazillion possible variations and has been around as long as the mashed potato.
Sometimes people call them pancakes, patties or cakes. Whatever you want to call them is fine, just don’t forget about these when you have bowl of left over mashed potatoes in the fridge.

Here’s what you need to know…
- Leftover Mashed Potato Cakes can be as simple or elaborate as you want. I still love them with just the basics: cold mashed potatoes mixed with diced sweet onion dredged in seasoned flour, dipped in beaten eggs, then again in the flour.
- These are best cooked in a nonstick skillet lightly greased with vegetable oil. A well seasoned cast iron skillet works well too.
- Don’t flip the potato cakes too many times. I try to turn them only once so they won’t spread. When the potatoes get hot it’s harder to hold their shape.
- Fried Potato Cakes stay molten hot in the middle for a long time. Be careful with your first bite!

How to make an easy Potato Cake
- Mix cold leftover mashed potatoes with finely diced sweet onion. Form the mixture into a thick hockey puck about 3-inches wide by 1-inch thick.
- Dredge the potato ball in the seasoned flour, then the beaten egg, then back into the flour again.
- Transfer immediately to a hot nonstick or cast iron skillet lightly greased with cooking oil.
- Cook until the potato cake is dark brown on one side. Carefully flip the cake and continue cooking until browned on both sides.
- Transfer to a plate or platter, in a single layer, and serve topped with minced chives, parsley or green onions and a little sprinkle of paprika.

Common mistakes to avoid when making potato cakes
- Hot or warm mashed potatoes will be too loose to form into a ball. Use cold mashed potatoes for the best texture.
- Don’t add too many additional ingredients which will make it hard for the mashed potato mixture to hold together.
- Cook one side at a time until deep golden brown. Don’t turn the potato cakes more than once if you can help it.
- Allow the extra egg to drip off before transferring to the flour again.
- Don’t over grease the pan. For a light crisp crust there’s no need to deep fry the potatoes.
- Wipe out the skillet between batches for the best flavor and appearance.

What to serve with Potato Cakes
Almost anything goes well with Mashed Potato Cakes. Roast turkey or beef, stews and fish are all great with this simple side. Anything you’d serve with mashed potatoes would be great.
Serve these for a hearty breakfast with scrambled eggs or with a fried egg on top.

Add-ins and variations
As mentioned above, Mashed Potato Cakes are easily adapted to any of your favorite add-ins and toppings.
Think loaded potatoes or distinctly flavored mashed potatoes. These ingredients can be mixed in or used as a topping:
- crisp fried bacon, minced
- top with a fried egg for a hearty breakfast
- shredded cheddar cheese
- Dijon mustard
- ranch dressing
- dollop of sour cream
- gravy
- garlic powder or onion powder
- sliced green onions
- minced parsley
- finely chopped chives
- paprika
- cayenne pepper
- salsa
- ketchup
- hot sauce

Being a child of the depression, my mom used all leftovers for something. Nothing went to waste. If she had a spoonful of corn, peas or green beans she would drop them all together in a freezer container with the other leftover vegetables. When it was time to make soup she’d bring out the frozen layers of vegetables and add it to the pot. Nothing edible was thrown away and it all tasted great to us.
Thanks for the great recipes mom. I loved these as a kid and still do!

Mashed Potato Cakes
Ingredients
- 4 cups cold mashed potatoes
- ½ small sweet onion finely chopped
- 2 large eggs lightly beaten
- 1 cup all purpose flour (126g) plus more if needed
- salt and pepper to taste
- Canola or other vegetable oil for cooking
Instructions
- Place the flour, salt and pepper in a bowl for dredging. In another bowl whisk the eggs until lightly beaten.
- In a large bowl mix the mashed potatoes and onion together. Add a little oil to a large nonstick skillet and warm over medium heat. While the skillet preheats, make a ball of potatoes using approximately 2/3 cup or (150g) of the mixture. It should be like a very thick hockey puck approximately 3-inches wide by 1-inch thick.
- Dredge both sides of the potato cakes in the flour Next dip the cakes in the eggs turning to coat both sides. Allow any excess egg to drip off. Transfer to the flour again and turn to coat.
- Cook each cake until golden brown on both sides turning only once. Cook only a few at a time taking care not to over-crowd the pan. Remove the cooked potato cakes to a paper towel lined plate or small baking pan and keep warm.
- Carefully wipe out the skillet with paper towels between batches. Add little more oil if needed before adding the next batch. Serve immediately.
Recipe Notes
- Store leftovers in a airtight container in the refrigerator for up to 3 days.
- Reheat in a small lightly greased nonstick skillet until warmed through, turning once.
- Serve with gravy, ranch dressing, sour cream, ketchup, salsa, hot sauce, minced parsley, paprika, sliced green onions or chives.
- Consider add-ins like crisp cooked bacon, shredded cheese or Dijon mustard

I haven’t tried yur potato pancake recipe as yet. But one thing I learned…if you want to make an instant cake without the egg, flour, etc, use cold leftover instant mashed potatoes. Regular potatoes too moist…won’t hold up. Fry quickly, and turn only once.
Tricia Buice
Sounds great Lucinda. Thanks for the tip!

Tricia, I had to laugh at your comment about not liking ground beef, I too am not a fan but with a house full of boys and my husband I feel bad that I don't serve it for THEM more often. I decided to try a double recipe of your meatloaf this past weekend and I have to say it has been a great success! My kids aren't always big leftover fans, but they keep going back to the fridge for a

I am such a sucker for mashed potatoes and these sound wonderful Tricia! My mom was the same as yours, very frugal and making delicious things from almost nothing. She had a German heritage and she made wonderful potato dumplings with a browned butter crumb topping. They were to die for and we would actually fight over them 🙂 I will try your yummy looking potatoes, I have the feeling that they

They look mighty fine Tricia – I've never tried breading them, but it made for a pretty crust.

My mom made these as well, but she used cheese instead of onion. I bet they'd be good with both. 🙂

These look amazing, Tricia! I've made latkes before, but this version sounds fantastic. I'm going to compare our recipes now. I am loving the look of the crust on yours. Mine were much more like traditional pancakes.
