Crispy Fried Mashed Potato Cakes - How and Why
My dad was a classic meat-and-potatoes guy. Vegetables made an appearance, sure…but dinner was built around beef, chicken, and a steady rotation of potatoes.
Mashed, baked, fried, scalloped—we had them all. But one of my favorites? Fried mashed potato cakes, made from leftovers the next day.
Simple, humble, and somehow even better the second time around.
Mom kept hers basic—just leftover mashed potatoes, egg, flour, salt, and pepper. They were good. Really good.
But over time, I added one small upgrade: a light panko coating.
That’s the difference-maker.
You still get that soft, creamy potato center, but now it’s wrapped in a golden, crispy crust that gives you a little crunch in every bite.
To make them, you simply:
- Mix cold mashed potatoes with egg and flour until a soft dough forms
- Shape into cakes
- Coat lightly in panko
- Pan-fry until golden and crisp
That’s it. Nothing fancy—just a smart way to turn leftovers into something you’ll actually look forward to.
Crispy Pan-Fried Mashed Potato Cakes
Ingredients
- 2 cups cold mashed potatoes leftover, real potatoes only)
- 1 extra large egg lightly beaten
- ⅓ cup all-purpose flour more as needed
- 1 cup panko breadcrumbs or as needed
- oil for frying
- 1 teaspoon butter for flavor
Additional Add-Ins
- chopped parsley
- chopped green onion
- grated cheese Gruyere or cheddar
- caramelized onions
If making thicker potato cakes, preheat the oven to 350ºF.
Instructions
Mix the Base
- In a bowl, combine mashed potatoes, egg, flour, salt and pepper. Mix until a soft, slightly sticky dough forms. Add a bit more flour, if needed, so the mixture holds together.
Shape
- Form into cakes, thick or thin depending on your preference.
Coat
- Place the panko into a wide bowl or pie tin, press each cake into the panko, coating both sides.
Heat the Pan
- Heat the oil in a 12-inch heavy bottomed frying pan, add the butter. Heat over medium heat until the butter stops forming .
Fry
- Add the potato cakes and cook, turning once, until golden brown, about 3 - 4 minutes per side.
Finish (for thicker cakes) in a 350ºF oven
- For thicker cakes, transfer the pan to the preheated 350ºF oven for 5 - 10 minutes or until heated through.
Notes
Recipe Notes
- Use cold mashed potatoes – they hold together better and fry up crispier than warm potatoes.
- Sticky is good – the mixture should be soft but hold its shape. Add flour a tablespoon at a time if needed.
- Don’t skip the panko – it’s what gives you that crunchy crust. Regular breadcrumbs work, but won’t be as crisp.
- Hot pan = crispy cakes – make sure the oil and butter are hot before adding the cakes to prevent greasiness.
- Oil + butter combo – oil keeps things from burning, butter adds flavor.
- Thick vs thin – thick cakes may need a few minutes in a 350°F oven to heat through; thin cakes cook through in the pan.
- Keep warm – hold cooked cakes on a rack in a low oven (200°F) if making in batches.
- Flavor boosters – try green onion, cheese, or caramelized onions mixed in for extra depth.

Ingredients & Add-Ins (What You Need to Know)
- Mashed potatoes – Use cold, preferably leftover mashed potatoes. They hold together better. And use real potatoes—this is not the place for Potato Buds.
- All-purpose flour – Helps bind the mixture so the cakes hold their shape.
- Egg – Adds structure and richness.
- Panko breadcrumbs – The secret to that light, crispy crust.
- Oil + butter – Oil for frying, butter for flavor (that combo matters).
Optional Add-Ins (highly recommended):
- Chopped parsley or green onion
- Grated cheese (Gruyère or cheddar is a favorite)
- Caramelized onions (what I used here—and worth it)
This is also a great place to use plain mashed potatoes or something with a little built-in flavor, like mashed potatoes with carrots or caramelized onions.
Tips for Success: Crispy Potato Cakes Every Time
- Cold potatoes are key
Warm mashed potatoes are too soft. Cold potatoes = better structure. - Sticky dough is good
It should feel soft and a bit tacky. That’s what keeps the cakes from falling apart. - Heat your pan first
If the oil isn’t hot, the cakes absorb it instead of crisping. That’s how you get greasy instead of golden. - Use just enough oil
Lightly coat the pan, then add a pat of butter for flavor once hot. - Watch the butter
When it stops foaming, you’re ready to add the cakes. - Don’t rush the crust
Let them sit and brown properly before flipping. That’s where the crunch comes from. - Thick vs. thin (your call)
- Thick cakes = crispy outside, soft center (may need oven finish)
- Thin cakes = more crunch, cook through in the pan
- Finish in the oven if needed
If your cakes are thick or browning too fast, pop them into a 350°F oven for 5–10 minutes to heat through.
(Cold centers are not the goal here.)
FAQs
It should be soft and slightly sticky, but hold together when shaped. If it feels too loose or falls apart, add flour a tablespoon at a time until it holds its shape.
Yes, but the crust won’t be as crisp. Panko’s larger flakes give you that lighter, crunchier coating.
Gruyère is excellent, especially with caramelized onions. Cheddar works well too, particularly with green onion for a classic combo.
Any heavy-bottomed skillet works. Cast iron is ideal for browning, but nonstick or stainless steel are fine—just make sure the oil is hot before adding the cakes.
They were likely too thick or cooked over heat that was too high. Lower the heat and, if needed, finish them in a 350°F oven for 5–10 minutes until heated through..
Yes. Shape the cakes and refrigerate for a few hours (or overnight). Fry just before serving for the best texture.
Yes. Freeze shaped, uncooked cakes on a tray, then transfer to a container. Cook from frozen or thaw first—just allow a little extra time.
Not recommended. They tend to be too soft and lack the structure needed to hold the cakes together.

I remember them being made with 1 egg and flour when I was about 5,6 years old with fried eggs and sausage or bacon, bisquets and gravy
Linda Baker says
Are you saying you used the fried potato cake in place of the biscuit? Wow, that is an interesting thought. Now I'll have to try it. Cheers ~ Lindy
Tracy R pease says
So if i have no panco what can i use
Linda Baker says
Hey Tracy, If you have no panko mixx then you might want to try oatmeal flakes or crushed saltines or Ritz crackers. Dried bread will also work. Tear it, dry it, smash it, roll it, add it. Cheers ~Lindy
Caroline Esquivel says
Ooof those are brilliant suggestions bc I always have one or the other of those things if I do not have panco. For toast bread supper crunchy but not burnt and then crush it upppp
Kathie Dreiling says
I made these potatoes cakes tonight for dinner I didn't have any panco mix so I use corn bread mix ,and I added chives , cheese sour cream plus what it called for it turned out very good but very messy.
Linda Baker says
I'm not exactly clear where you used the corn bread mix, on the outside or on the inside or both, and perhaps the sour cream added a bit too much liquid to the mix. But I'm glad they were tasty, even if messy. Cheers ~ Lindy
