If you’re always trying to figure out what to make with those leftover mashed potatoes-this is the recipe!
After the holidays, I found myself with quite a bit of mashed potatoes. These potato pancakes from leftover mashed potatoes are just truly delicious! Usually I make the matafan-fluffy mashed potato pancakes (from Dorie Greenspan). The matafan are fantastic, but a little fussy compared to this potato pancake.
These come together with a few simple steps and taste like fluffy latkes! I was seriously considering calling them “fluffy latkes”, because that is what they tasted like. It may seem that you could make a potato cake by just adding an egg.
It won’t work with just an egg. The trick is to add some flour to bind it all together, and a little bit of cheese and onion to jazz up the flavor (GF flour and dairy-free cheese are great subs!).
Once you get the mixture together, lightly coat it with flour, which helps to get that amazing crispy exterior. It all fries up for a few minutes per side, and soon you’ll have gorgeous golden brown exterior and a dreamy and creamy interior!

shredded cheese* ( I used vegan cheese, but shredded mozzarella is fine or cheddar, or a combo of whatever cheese you like. OR leave out the cheese) - onion (I used red onion, but use sweet onion, scallion or even shallots)

How to make these cheesy leftover mashed potato pancakes
In a large bowl, add all of the ingredients.
Stir them all together to combine.
If you’re making the sauce, now is the time to make it. If not, go on to cooking them up.
Use an ice cream scoop or spoon, scoop out the mixture into 6 portions. Roll each portion into a ball and form it into patties or cakes which are about 1/2- inches in thickness. Coat each cake evenly in a thin coating flour and set aside.
Place remaining flour in a shallow dish and dredge each pancake lightly in flour.
Heat the oil in a large skillet (cast iron is great for this recipe if you have one) on medium heat. Make sure you use enough oil to coat the entire bottom of the pan.
Add the potato pancakes into the hot oil, three at a time, don't overcrowd the pan. Gently flatten with the back of a rubber spatula.
Cook the patties until bottom is browned and sides are set.
Carefully flip the patties and cook for another 3 to 4 minutes, until browned and cooked through.
When you flip, be sure that the entire spatula is under the pancake. If you use just the front of the spatula you’ll end up breaking the pancake as you flip it. You have to fully support the entire perimeter of the pancake to make a nice flip.
Repeat with the rest of the patties .
Serve immediately with the aioli sauce or sour cream (use your favorite dairy-free if you’re dairy-free).

Top tips to make this leftover mashed potato pancake recipe
- To make these pancakes gluten-free, substitute the flour for gluten-free 1:1.
- To make these pancakes paleo, use cassava flour 1:1.
- Start with one egg. If you find the mixture too dry and feel it could use another, go ahead and it in (I used just one egg).

FAQ'S
The trick to getting them to stick together is adding enough egg to bind the potatoes together. If your pancakes are still falling apart after adding an egg or two; try adding some breadcrumbs or Parmesan cheese to act as a binder. If you don’t have breadcrumbs on hand, crackers or oats can also work. You could even try adding some finely chopped onion and garlic for an extra flavor boost!
What is the difference between latkes and potato pancakes?
Latkes are a traditional Jewish dish made from grated potatoes and usually served with sour cream or applesauce. Potato pancakes, on the other hand, are typically made from mashed potatoes and often fried in butter or oil. Both are delicious but have slightly different textures. Latkes tend to be more crispy while potato pancakes can be fluffy.
If your potato pancakes are coming out mushy, it’s likely because you didn’t squeeze out enough moisture from the mashed potatoes. Be sure to use a clean kitchen towel to really press down and get as much of that excess water out as possible.
Potato pancakes are popular all around the world, but they’re most often associated with traditional German and Austrian cuisine. In Germany and Austria, potato pancakes are usually served as a savoury snack or appetizer, usually topped with apple sauce or sour cream.

Notes
- Keep in mind that the leftover mashed potatoes will vary in consistency. It all depends on how you made your mashed potatoes (how much milk or butter was added)
- If after combining the mashed potato pancake mixture it seems a bit dry and has difficulty coming together, add one more egg. If the mixture seems too wet, add a small bit of flour, 1 tablespoon at a time, until you get a nice and cohesive mixture.
Paleo: To make these potato pancakes paleo, use cassava flour 1:1. Cheese: I used vegan mozzarella shreds to make it dairy-free. Go ahead and use your favorite with dairy mozzarella shreds or even cheddar.
Onion: I used red onion, but go ahead and use scallions, sweet onion or even chives.
Cook: Cook them up a few at time. You want to make sure you don’t overcrowd them in your pan (if it’s a large pan, you could probably fit them all at once). Aioli sauce:
If you have anchovy filets on hand, chop up a couple to add to the sauce. If you do add anchovy, you will not need any salt in the sauce.
Refrigerate for up to 1 week. Make them in advance: Pancakes could be formed into shape one day ahead and stored in the fridge. Remove from fridge 10 minutes before frying. Reheat on a baking sheet at 350F for 8-10 minutes
Freezing: Potato pancakes could be stored in a single layer in a zipped lock freezer bag or an airtight storage container. Keeps in freezer for up to 2 months.
