- If you want to sneak some veggies into these potato cakes, add some mashed cauliflower, chopped spinach, or finely shredded carrots.
- The flour and egg act as a binder to keep these together. But you can also refrigerate the batter before frying to ensure they don’t fall apart.

How to Make Mashed Potato Cakes
1. Mix the Base
To your mashed potatoes, add egg and mix them up really well. Then add flour. Stir it up really well with a fork until well blended like this. It will be very thick and sticky.
You can also add some finely diced onion or green onion at this point as well.
2. Prep the Skillet
Heat just a little bit of butter or oil (about two tablespoons of either , it doesn’t take much) in the bottom of a large skillet and place it over medium heat for two to three minutes, or until hot.
This is important because if you don’t heat your oil first, your potato cakes will be greasy.
3. Scoop and Flatten
Drop heaping spoonfuls of the potato mixture into the hot oil. Use the back of an oiled spoon to gently press down on each scoop, shaping them into patties about 1/4-inch thick.
4. Fry to Golden Perfection
Fry the cakes until the bottoms are deeply golden and crispy. Carefully flip them over and brown the other side. This usually takes about 3–5 minutes per side.
Once they are golden on both sides, remove them to a paper towel-lined plate to drain any excess oil. Serve them while they’re hot and crispy!
Storage
If you have leftovers, they store well in an airtight container in the fridge for up to 4 days. To get that crunch back, I highly recommend using an air fryer or a skillet over low heat. The microwave will make them soft, but a quick toast in the air fryer at 350°F for a few minutes will make them taste just-fried again. You can also freeze these for up to 3 months; just wrap them individually in foil first!
How To Serve Mashed Potato Cakes
Serve your potato cakes with turkey leftovers over the holidays or as a side alongside main dishes like meatloaf, roasted chicken, or beef brisket any time of the year. You can even serve them with bacon and eggs for breakfast or as an appetizer with apple sauce or sour cream for dipping. The choice is yours!
Ingredients
- 2 cups cold leftover mashed potatoes
- 1 whole egg
- 1/4 cup flour all-purpose or self-rising
- 2 tbsp finely diced onions optional
Instructions
- Mix the egg into the mashed potatoes with a fork until well blended. Add the flour and onions (if using onions) and mix well. The mixture will be very stiff.
- Pour approximately 2 tablespoons of oil into a cast-iron skillet and heat over medium heat.
- Scoop out heaping tablespoons of mixture into the hot oil. Dip the back of a spoon into the oil and then the mashed potato mixture to flatten to about a 1/4-inch thick. By dipping the back of the spoon into the oil, the spoon will not stick to the potatoes, making flattening them much easier.
- Fry until golden brown and then flip and continue to brown the potato patty on the other side.
- Remove to a paper towel-lined plate to serve.
Christy I was raised on these. My mom would always fix extra mashed so she could make these the next day. She was born n raised in England. She learned how to do this from my Pennsylvania Dutch grandma, so it isn’t just a southern thing. Love, love, love them.
Oh my! I will have to be honest… I was a little skeptical when I read the title. No one around here even knows what potato cakes are! They think they are those shredded potato thingys… I call those hashbrowns. But after reading the whole post… Oh my! My dad made these all the time for breakfast! I make them every once in a while. My husband had never had them before… can you believe that! Guess it is more of a “southern thing”? MMMMMM…. we are having mashed potatoes tonite. Can’t wait till breakfast in the morning!!!!!!!!!!!!!!!!!!!!! Thanks for another great reminisce, Christy!
I think you are right, it must be a southern thing. So glad this recipes brought back memories for you!!
Thanks so much for this recipe! I always loved my mom’s potato cakes but can’t seem to get them right when I do them myself!
Let me know how they turn out Elizabeth!
CHRISTY, MY MAMA USED TO MAKE PATTIES LIKE THESE WITH LEFT OVER CROWDER PEAS. SHE WOULD ADD SOME CHOPPED ONION IN THEM.
Hmmm, now that is different. I might just have to try that. Thanks for sharing!
I used to make these all the time when my 4 kids were still at home and they loved them! Now that I’m alone, I’d forgotten all about them – will have to try them again soon!!
I always made mine into patties then dipped in flouf and fried in butter. I will try them this way next time .
Hi Christy, thanks for the memories! My mother made these (breakfast, lunch, supper) – she added minced onion, but I’m sure without would be just as wonderful. My mother also used to make sweetened canned tomatoes, served over cornbread. Was anything ever so good!! Does that bring back a memory for anyone else out there?
