Ingredient notes
Make without leftover mash
Fresh family cooking usually wins, but when life gets busy with kids, work and more? 100% from scratch cooking is not always an option.
If you’re looking for a quick-fix food, these work just as well with instant mashed potatoes.
Cheese
Cheddar is very delicious in these, but pretty much any shredded cheese will work. Gouda or Mozzarella work just as well!
Add more flavor
You can add chopped chives, finely diced ham, cooked and crumbled bacon, chopped green onions… to the pancake batter, if you like. So many ways to switch up the flavor here, and they come out delicious any way you make them.
How to make potato cakes
Combine all ingredients: Add all ingredients to a bowl and stir them together until smooth.
The amount of flour you need heavily depends on the consistency of your mashed potatoes, so start with the amount given in the recipe, then increase from there if the batter is very runny.
Shape cakes: A cookie scoop works great to shape the potato mix into cakes. If your mashed potatoes were very firm, you may need to shape them into discs by hand.
Otherwise just drop them into a sizzling hot skillet with oil and lightly flatten with the back of a rubber spatula.
Cook cakes: These turn out best when pan-fried.
Just heat some oil in a large nonstick skillet, then cook them on both sides until browned and crispy on the outside and heated through all the way on the inside.
These are best served right away while hot and fluffy!
Mashed Potato Pancakes FAQs
There are differing opinions on this, but per the USDA, refrigerate leftover mashed potatoes within 2 hours, and eat them within ~3 days.
While these do taste best fresh, they can be frozen for convenience/to save leftovers.
Freezer instructions
To freeze: Let the potato cakes cool, then flash-freeze them on a baking sheet in a single layer until solid (1-2 hours) before transferring them to a freezer-friendly bag or container. Label with the name and use-by date (freeze for up to 3 months).
To reheat: Take as many potato pancakes as you need from the bag or container and defrost them on the counter for 10-15 minutes. Reheat in the oven at 350°F or in the microwave until steaming hot all the way through.
Serving ideas
These are delicious with sour cream, applesauce or cranberry sauce (great to use up those leftovers, too!).
If you want to make these for a St Patrick’s Day spread (kind of a cheat’s Irish Potato Pancake, or Boxty), they go great with Irish Stew!
And these leftover mashed potato cakes would work just as well as a side dish or a fun appetizer, you could even add some fun toppings like smoked salmon or crispy bacon!

Leftover Mashed Potato Cakes
Recipe details
Ingredients
- 2 cups cold mashed potatoes
- 2 large eggs
- 2 oz finely shredded cheddar cheese
- 6 tablespoons flour or more depending on how creamy your potatoes are
- Oil or nonstick cooking spray, for frying
Instructions
- Make potato cake batter: Stir the mashed potatoes, eggs, cheese and flour together in a large bowl. Start with 6 tablespoons of flour and add more if needed. You should end up with a slightly sticky, soft dough that can be shaped into disks.
- Shape cakes: With a cookie scoop, scoop out balls from the potato dough and flatten them into thick discs between damp hands. Making your hands slightly wet will prevent the dough from sticking to them.
- Cook cakes: Heat the oil or nonstick cooking spray in a large frying pan over medium heat. Place the potato cakes in the hot frying pan and cook them until golden brown on either side, about 3-5 minutes each. Serve hot.
Notes

I definitely have some mashed potato recipes you can try – a regular and an instant pot variety. Both make great leftovers for mashed potato cakes 😉
Laurie says
I used one egg and threw in some green onions, salt n pepper onion powder and a little baking soda. Very good
Nora says
Glad you think so, Laurie!
Sheena says
I always make too much mashed potatoes, as I always expect company for dinner or the adult children (with friends). Lol. I love making this and freezing little patties, so they can be fried at any time. I’ve also found that if you freeze them, the kids can just toss them into the airfryer for a quick snack.
Tracy Hambleton says

Lara M says
I’ve tried this once before, but it didn’t work out, AT ALL. It wasn’t this recipe, but from someone else. This recipe had the right amount of egg & potatoes. Even the flour amount was perfect. They turned out absolutely amazing! I’ll definitely make this again. Tysm!!
Jennifer says
Love it love it love it. My husband loved it too. I feel like this is a recipe that could be adapted with other mix-ins like scallions or bacon bits. I topped these with some leftover chicken and gravy. WOW! So good. Thank you.
Rhonnie says
Delicious! A new favorite side dish! I didn’t know how much oil to use in pan and went overboard so they were greasy but will use far less next time. Mine were in 1/4″ of oil. I used grated Mexican Sargento cheese and chopped onions, so good!
Melanie Franceschi says
These were a great fix for leftover mash. I actually grew up eating these at my aunts house and I’m 74. The recipe was simple enough for anyone to figure out. By the way you did not waste my time. !!!!!! Some people cannot be respectful.
Todd says
My husband asked enough for more of these that it’s become our go-to weekend breakfast. I add garlic salt, black pepper, and dried chives into the mixture for a touch of extra flavor. We absolutely love this recipe. Thank you so much!
