Ingredients
Gathering your gear for this leftover mashed potato pancakes recipe is half the fun. The best part? You probably have 90% of this already lurking in your kitchen.
No fancy trips required.
- 2 cups leftover mashed potatoes (the star of the show!)
- 1 large egg, lightly beaten
- 1/4 cup all-purpose flour (or a 1:1 gluten-free substitute)
- 2 tablespoons finely chopped fresh chives or green onions
- 1/4 cup shredded sharp cheddar cheese (optional, but highly recommended)
- 1/4 teaspoon garlic powder
- 1/4 teaspoon smoked paprika (for a little ~drama~)
- Salt and freshly ground black pepper to taste
- 2-3 tablespoons olive oil or butter for frying
- Sour cream and applesauce for serving (the classic duo)
Step-by-Step Instructions
- Mix your base. In a medium bowl, combine the cold leftover mashed potatoes, egg, flour, chives, cheese, and spices. This is your glorious potato pancake batter.
Don’t overmix it; just bring it together until no dry streaks of flour remain.
- Heat your pan. Place a large non-stick skillet over medium heat and add your oil or butter. You want it hot enough that a tiny bit of mixture sizzles on contact, but not so hot it instantly burns.
Patience is a virtue here.
- Form the patties. Scoop about 1/4 cup of the mixture for each pancake and form it into a patty about 1/2-inch thick. Pro tip: If the mixture is too sticky, wet your hands slightly.
This is the secret to perfect, non-sticky patty shaping.
- Fry to perfection. Carefully place the patties in the hot skillet. Cook for 3-4 minutes per side, or until they’re deeply golden brown and crispy.
Resist the urge to press them down with your spatula! You’ll squeeze out all the fluffy goodness.
- Drain and serve. Transfer your beautiful, crispy leftover mashed potato pancakes to a plate lined with a paper towel to absorb any excess oil.
Serve immediately with a generous dollop of sour cream and maybe some easy homemade applesauce.
Storage Instructions
Yes, you can absolutely save these for later! Let them cool completely to room temperature first. For the fridge, place them in an airtight container separated by parchment paper.
They’ll stay fresh for up to 4 days. For the freezer, lay them in a single layer on a baking sheet to flash freeze for an hour, then transfer to a freezer bag. They’ll keep for up to 3 months.
Reheat in a toaster oven or air fryer for the best crispy results.

Common Mistakes to Avoid
- Using watery mashed potatoes. If your leftovers are soupy, your pancakes will be a sad, sloppy mess. Add a bit more flour to compensate.
- Flipping too early. Let that gorgeous crust form! If you try to flip and it sticks, it’s not ready.
Wait for the edges to look set.
- Overcrowding the pan. This steams the pancakes instead of frying them. Give them space to get crispy. Cook in batches if you need to.
- Skipping the resting time for frozen pancakes. Don’t throw them straight from the freezer into the pan.
Let them thaw in the fridge first for the best texture.
Alternatives and Variations
This recipe is a fantastic base for experimentation. For a gluten-free version, simply swap the all-purpose flour for your favorite GF blend. To make it vegan, use a flax egg and skip the cheese or use a plant-based alternative.
