Pan Fried Leftover Mashed Potato Cakes with Cranberry Honey Mustard

Creating completely new and interesting dishes with Holiday Leftovers might be my favorite part of having them. From using the turkey in casseroles (like I did here), to piling all of your favorites high onto a thick piece of bread—you can’t go wrong. One dish that typically has so much leftover you don’t know how you’re going to finish? Mashed Potatoes. I would never throw away perfectly good potatoes, so I’m going to share how I create a completely new dish with leftover mashed potatoes. Enter… Potato Cakes.

Mashed Potatoes are one of my absolute favorite side dishes, by far. Not even just for the Holidays, they really pair so well with so many difference recipes. Over the years, I’ve experimented with adding various ingredients to perfect my mashed potato recipe, and I think I’ve got it. My mashed potatoes are simple, creamy as can be, and full of really rich delicious flavor.

Before we can start frying up our potato pancakes, we need to prepare our main ingredient— mashed potatoes. When using Thanksgiving leftovers, these will obviously not be freshly made and that’s actually preferred! Typically, when I make them fresh for this recipe, I pop them in the fridge for a little bit. They are so much easier to work with when they’re cold.

You Will Need:

  • 7-8 Washed Gold Potatoes (I leave the peel on mine because no one in my family minds, but this is totally a personal choice. You can also use Idaho, Russet, Red, or even Sweet Potatoes—again, preference)
  • 1 Stick of Unsalted Butter
  • ½-ish Cup of Heavy Cream—sub for milk if needed.
  • 1/3 Cup Sour Cream
    *Optional Additives—Shredded Cheese, Fresh Cut Chives, Fresh Cut Dill.

Start by putting a big pot of water on the stove to boil. Once it’s gotten to at least a rolling boil, generously salt your water. While you’re waiting for the water to boil, go ahead and wash, peel (if prefer your potatoes peeled), and cut your potatoes. I cut mine into fourths so that they cook through a lot faster, and I find that they’re easier to mash when they’re in smaller chunks.

Once your potatoes are fork tender, strain them and return them to the hot pot (on a cool burner). Cut your stick of butter into fourths and toss it in, along with your milk and your sour cream, and mash away! I eye ball ALL of these amounts! So, just add the liquids a little at a time until they’re the right consistency. We do not want runny mashed potatoes here. Don’t be freaked out by the sour cream, it just adds a richness and depth to the flavor of your mashed potatoes. Of course, the more that you add, the more that sour cream taste will come through. My husband does not like sour cream, but he likes my mashed potatoes.

(This is also where you would add things like chives, dill, and cheese—just be mindful if you are planning on using these leftovers for mashed potato cakes that they *might* not be good with every sauce option.)

Now, for the reason that we’re here: The Pan-Fried Leftover Mashed Potato Cakes!

These are seriously so delicious, but I love potatoes in all of their many forms. You can have this with some eggs for breakfast, throw it inside of your Leftover Thanksgiving Turkey sandwich, or eat it alone dipped in some ranch, ketchup, or the cranberry mustard that we will be making today to pair with this. Heck, pour some gravy on top of it…that’s decadence.

You will need:

  • 3 Cups Cold Mashed Potatoes
  • 3 Large Eggs
  • 10-12 TBSP Flour (Start with 10 and add more as needed, this will depend on how creamy your potatoes are)
  • Oil, for frying

Combine your cold mashed potatoes, egg, and flour into a bowl and combine thoroughly. This will be where you see if you need to add more flour. We don’t want the mixture too thick, but they won’t fry well if they’re really runny. Use your best judgment here.

Using an ice cream scooper or a spoon, spoon out balls of the potato dough and flatten them into semi-thick discs. You can use a biscuit cutter for this step too, if you want—just lay all of the potato dough out and cut. (Pro-Tip: Keep your hands a little damp to prevent the dough from sticking to them).

Heat your oil in your pan (I used this coconut oil from Nutiva—I love that it’s squeezable) over medium heat. Then place your cakes into the pan (don’t crowd them here… 3-4 at a time depending on pan size) and cook them until golden brown on both sides, about 3-5 minutes each.

This is the color we’re looking for here when they turn over. You can gauge when you need to turn them by keeping an eye on the edges. When they’re golden brown, flip the.

How yummy do these look? They are best served hot, and don’t really do well sitting for very long… they will lose some of their fluffiness that way.

Cranberry Mustard Sauce

I’m a huge lover of dips and wanted to keep this dip flowing with the Holiday theme—so I made a Cranberry Honey Mustard to serve with the Potato Cakes. This is really simple and easy to whip up, and packs a lot of flavor!

(I did this ALL to taste in a ramekin, so I’m just kind of guessing measurements here… I always recommend cooking by taste).

  • 1-2 TBSP Yellow Mustard
  • 1/2 Can Cranberry Sauce (w Berries)
  • 1-2 TBSP Honey
  • 1 TBSP Brown Sugar

I dumped the cranberry sauce into my ramekin and just added ingredients and mixed until it tasted comfortable for me. I actually prefer it to be a little more honey-mustardy than cranberry as far as flavors go, but adjust for your tastes.

(If Cranberry and Mustard ain’t your thing, try this Bacon Ranch Dipping Sauce):

  • It’s the weekend! ⠀
You know what that means! ...#StayHome and #FlattenTheCurve. ⠀
▪️(Thank you to all of the essential workers around the country who don’t have this luxury and are depending on us to do what we can to help.) ▪️ It’s scary, I know. 
It feels isolating, I know. ⠀
It’s frustrating, I know. ⠀
You are craving some normalcy, I know. ⠀
But look, the sooner we all fall in line and do the *one thing* we know can work and stop the fast spread of this virus, the sooner we can get back to our usual routines. ⠀
We are all in this together...⠀

  • A Little After Dinner Coloring. 
Trying to break up activities here so that no one gets bored. #creativeathomechallenge prompt today was craft/art, and it’s not what I had in mind...but he enjoyed it! 
What has been your favorite thing to enjoy with your kids during this time at home?
  • ☣️ STOP ☣️⠀
We have to act NOW to save lives. Listen up.⠀
While panic is never preferable- if that's what it takes for you to stay home and slow the spread, then maybe you need to get scared. ⠀
People are exponentially spreading this disease with no symptoms. We have all GOT TO STAY HOME. No more lunch with the ladies. No more playground meetups. ⠀
There are otherwise healthy children and young adults on *limited supply* ventilators right now. This virus is brand new to the entire world and it is ravaging people's bodies in unexpected fatal ways- and no, not just the elderly or compromised.⠀
Math is math. We are already projected to run out of lifesaving equipment and supplies very quickly. ⠀
This is not media hype, this is not a hoax, this is real. It may be easy to forget that we are in the middle of a dangerous pandemic while the sun is out, traffic is light, and you are off work.⠀
There are no sirens going off or bombs exploding in your front yard, but I can promise you that we are in a very real crisis. However, we have SOME control.⠀
The longer we wait and the more we continue to socialize with each other and expose ourselves in public the longer we will be stuck in isolation, the longer people will be out of work, the longer our children won't have school, the longer our economy will suffer.⠀
Keep in mind that Wuhan did a very tight lockdown and they have STILL been quarantined for two months now and cannot lift the quarantine until they have gone 28 days without a new positive result. The US government has been very lax in comparison and this will not bode well for us if we don't do better NOW.⠀
This won't last forever, but our future WILL look a lot different based on the choices we make. ⠀
Just because the government did not force you to stay home or because your favorite restaurant, store or salon has chosen not to close does not mean you should leave your home.⠀
➡️*obviously this is intended for people who are VOLUNTARILY not staying home.*⬅️⠀

  • Well. This wasn’t what I was going for today #creativeathomechallenge. It’s been pretty chilly haha...puns (don’t let that beautiful sky deceive you) and my plans to get a picnic together for lunch this afternoon were ruined. Maybe I can do that finally on back yard day 😂😂
Trying to support businesses and third party delivery services like Door Dash and their drivers—they now offer contact free deliveries, which is greatly appreciated to get a mild feeling of normalcy, one of my favorite dinners. It’s something small and easy that you can do if you’re able. Some of these DD drivers are relying solely on people to still order so that they can make money. #stayhome #flattenthecurve #slowthespread
