They can top a shepard's pie or go into a batch of potato rolls.

I'm not a fan of leftover potatoes, but this is the one exception. I will make extra just to make these pancakes. Light and tender.

I do something similar to Ann's posted recipe but without whipping the egg whites. I like the patties fried in a lot of butter and seasoned with lots of freshly ground black pepper and either chopped green onion or chives. Totally savory and so delicious.

My mom used to make them for my breakfasts when we had leftover mashed potatoes, and I still love them. The biggest problem now is leaving enough mashed potatoes to make some. Mashed potatoes tend to get gobbled up here. Sometimes I make a meal of just them along with a quick pan gravy.

Ellie, what I call a potato cake is simply mashed potatoes formed into a small cake, dipped in flour with S&P, sauteed in a combination of olive oil and butter till a good crust forms. Applesauce goes well with it.

Sounds kinda' bland, but perhaps others can make some interesting additions.

Yum Ann ! That is a keeper recipe!

I always try and make extra while i'm at it...just for some cakes for breakfast. I've started not putting all of them out for dinner hiding a good amount for 'leftovers'. (sneaky).

A friend of mine makes salmon cakes for weekend brunch with the leftovers. Adds onion, red pepper, chives, dill, oldBay seasoning, rolls in panko. Keep forgetting i have a couple cans of AlaskanWild tin salmon...could add an egg to the mix.

I always add sauteed diced onions and sometimes cooked bacon to my potato cakes.

Potato fish (as my mom called them as a kid) - Salted cod and potato cakes. Very much a sentimental dish for my mom growing up during WW11 rationing.

I have a 16 year old son. Hence, there are never any leftover mashed potatoes.

But if there were....gnocci is a good way to use them up.

You're just not making enough, John :-)

I use leftover mashed potatoes to make cinnamon buns...the recipe just uses 1 cup though. I also add mashed potatoes to soup to make it thicker (or make potato soup).

Bubble and squeak. Fry up cakes of mashed potato and chopped cabbage until crispy.

Shepherd's pie for me! Or Potato Turbate...

I add flour, a beaten egg, shredded cheddar cheese and chopped green onion -- then fry in a pan. Yum! -- I miss potatoes (low carb diet :( )

carolb - what is Potato Turbate please?

Potato Turbate looks pretty well like a version of Shepherd's Pie (which technically, if made with beef, is a Cottage Pie, while a Shepherd's Pie is made with lamb, hogget or mutton).

You could make Pierogies stuffed with the mashed potatoes/cheese/and whatever else you want.

I like mixing them with shredded cheese, seasonings, chopped onion and sour cream and baking them in a casserole. Taste just like baked stuffed potatoes but much easier!

Potato Turbate was a dish I was introduced to in elementary school in the 60s/70s. It's pretty basic (ground beef in gravy & mashed potatoes) & the 'turbate' part refers to the potatoes being whipped, I understand. It even has its own FB page...

We used to make fish cakes something like this but you can use salmon instead of tuna or any other kind of cooked flaked fish.

GF's family used to make mashed potato candy, but it didn't have p butter in it like this one does...

Mom would add a beaten egg to leftover mashed potatoes, flatten them out in cakes and dredge them in slightly crushed cornflakes. Then fry. One of my very favorite leftovers! (I would eat only a tiny portion of the mashed on the first go just so there would be more left over to make into potato cakes.) Never heard of dredging in flour.

Ci_Lantro, how funny. My aunt did the same thing, sort of. Mix and egg and mixed onions and roll in crushed crackers (saltines). And bake in the toaster oven. I do that as well, when I remember. We don't flatten them, just leave them in mounds.

oooh, Jasdip, onions in the mix. Sounds yummy! I gotta' try that. With green onions, I think.

As long as you didn't mix in a bunch of other things, I'd make lefse.

cilantro - dredging in flour gives a crusty potato cake.
