Ingredients

For the Potato Cakes

  • 3 cups cooked mashed potatoes, cooled
  • ¾ cup all-purpose flour
  • ½ teaspoon salt
  • Oil, for frying

How to Make Grandma’s Potato Cakes

1. Prepare the Potato Mixture

Place the cooled mashed potatoes in a large mixing bowl. Add the flour and salt.

Mix until everything comes together into a soft dough. If the mixture feels extremely sticky, add a small amount of additional flour, one tablespoon at a time.

2. Shape the Cakes

Lightly flour your hands or work surface. Divide the mixture into small portions and shape each portion into a round patty about ½ inch thick.

Try to keep the cakes relatively even in thickness so they cook evenly.

3. Cook Until Golden

Heat a thin layer of oil in a large skillet over medium heat.

Carefully place the potato cakes into the pan, leaving enough room between them to flip easily.

Cook for about 3–5 minutes on each side, or until golden brown and crisp on the outside.

4. Drain and Serve

Transfer the cooked potato cakes to a plate lined with paper towels to remove excess oil.

Serve warm with your favorite toppings or alongside a main meal.

Helpful Tips

Use cold mashed potatoes: Chilled leftover potatoes are usually easier to shape and help the cakes hold together.

Don’t add too much flour: Start with the recommended amount and add more only if necessary. Too much flour can make the cakes dense.

Keep the heat moderate: Medium heat allows the outside to become golden while the inside warms through without burning.

Make them evenly sized: Similar-sized patties will cook at roughly the same rate.

What to Serve With Potato Cakes

These versatile cakes can be enjoyed in many ways. Try serving them with:

  • Sour cream and fresh herbs
  • Applesauce for a sweet-and-savory combination
  • Fried or scrambled eggs
  • Roasted vegetables
  • A fresh green salad
  • Grilled or roasted meats

Can I Use Leftover Mashed Potatoes?

Yes. Leftover mashed potatoes are ideal for this recipe. If your mashed potatoes already contain butter or milk, the texture may be softer, so you may need a little extra flour to make the mixture easy to shape.

Can I Make the Potato Cakes Ahead of Time?

You can shape the cakes ahead of time and keep them covered in the refrigerator until you’re ready to cook them. For the best texture, cook them close to serving time.

Final Thoughts

Grandma’s 3-Ingredient Potato Cakes are a reminder that simple ingredients can make wonderfully satisfying food. With mashed potatoes, flour, and salt, you can create golden, crispy cakes without complicated preparation.

They’re especially useful when you have leftover mashed potatoes and want an easy way to turn them into something completely new.
