Potato cakes are what happens when leftover mashed potatoes get a second chance and decide to show off. You take something soft and cozy, add a little structure, and pan-fry it until the outside goes deep golden with crunchy edges. It is comfort food that also knows how to bring the texture.

This is my go-to when the fridge has a container of mashed potatoes that is not quite enough for a full side dish, but way too good to toss. These cakes are fast, flexible, and the seasoning is fully in your control. I like mine with a little garlic and onion powder, a pinch of paprika, and enough black pepper to make you notice.

Why It Works

Crisp without drama: A hot skillet and a light flour boost give you that browned, lacy edge without deep frying.
Fluffy centers: Starting with mashed potatoes keeps the inside tender and creamy.
Leftover-friendly: This recipe is designed for already-seasoned mashed potatoes, so you can adjust as you go.
Freezer-friendly: Cook once, freeze, then re-crisp in a skillet or oven for quick breakfasts and sides.

Storage Tips

Refrigerate: Let potato cakes cool completely, then store in an airtight container with parchment between layers for up to 3 to 4 days.

Freeze: Freeze cooked cakes in a single layer on a sheet pan until firm, then transfer to a freezer bag with parchment between layers. Freeze up to 2 to 3 months for best quality.

Reheat (best for crisp):

Skillet: Medium heat with a thin slick of oil, 2 to 4 minutes per side.
Oven: 425°F on a sheet pan, 10 to 14 minutes, flipping once.
Air fryer: 390°F for 6 to 8 minutes, flipping halfway.

Microwave: It works in a pinch, but the cakes will soften. If you microwave, finish in a hot pan for 1 minute per side to bring the edges back.

Make-ahead tip: You can shape the patties, cover, and refrigerate them for up to 24 hours before frying. Cold patties are easier to handle and tend to crisp up beautifully.

Common Questions

Are potato cakes the same as potato pancakes?

Not exactly, and the names can vary by region. Potato cakes are often made with mashed potatoes, so they are creamy inside and more uniform. Potato pancakes are often made with grated raw potatoes, which gives a more shredded, latke-like texture. That said, some folks call any pan-fried potato patty a “potato cake,” so the method matters more than the label.

Why are my potato cakes falling apart?

Usually it is one of three things: the mixture is too wet, the cakes are being flipped too early, or the pan is not hot enough. Add flour a tablespoon at a time, chill the mixture for 10 minutes, and wait until the bottoms are deeply golden and set before flipping.

How much flour do I really need?

It depends on your mashed potatoes. If they are very buttery, creamy, or loose (hello, lots of milk or sour cream), you will likely need the higher end of the flour range. If they are thicker and drier, you may need less. The goal is a mixture that holds its shape when scooped and can be patted into a cake without sticking to everything.

Can I make these gluten-free?

Yes. Swap the all-purpose flour for a 1:1 gluten-free flour blend. If your mashed potatoes are very soft, a tablespoon of cornstarch also helps them hold together.

Can I bake potato cakes instead of frying?

You can. Brush or spray both sides with oil and bake at 450°F on a parchment-lined sheet pan for 18 to 22 minutes, flipping halfway. They will be a little less shatter-crisp than skillet cakes, but still delicious.

What should I serve with potato cakes?

They love a bright, tangy partner. Try sour cream and chives, applesauce, a squeeze of lemon, or a quick yogurt sauce. On the side, eggs, roasted veggies, or a simple salad are all great.

I have always had a huge passion for the culinary arts, people, working as a team, and so on. I wanted to pursue my love for cooking initially at Virginia Commonwealth University with a culinary arts degree; however, I instead decided to apply myself and acquire more practical skills. My end goal is to eventually open my own restaurant or similar establishment.

Kitchen Essentials

Large mixing bowl
Measuring cups and spoons
Large nonstick or cast iron skillet
Thin spatula
Sheet pan (for holding cooked cakes warm)
Wire rack (optional, helps keep them crisp)

I used to think leftover mashed potatoes had exactly two futures: sad reheating or shepherd’s pie. Then I started treating them like a base, not a side. Potato cakes are my favorite kind of kitchen alchemy because they feel fancy and snacky, but the truth is you are just giving yesterday’s potatoes a crispy jacket. I make them when I want something comforting that still has a little crunch and attitude, usually while standing at the stove eating the first one “for quality control.”
