Easy Potato Pancakes From Leftover Mashed Potatoes

Easy potato pancakes turn cold leftover mashed potatoes into crisp, golden patties with soft centers. A little egg and flour help them hold together, while a hot skillet creates a browned crust; serve them as a side, snack, or simple breakfast.

Ingredients

2 cups (480 g) cold leftover mashed potatoes
1 large egg (about 50 g, without shell)
⅓ cup (40 g) all-purpose flour, plus 1–2 tablespoons (8–16 g) more if needed
2 tablespoons (20 g) finely chopped green onion or chives
¼ teaspoon (1.5 g) fine salt, or to taste
¼ teaspoon (0.5 g) black pepper
2 tablespoons (30 ml) neutral oil, such as canola or sunflower, for frying; use more as needed between batches

These quantities assume the mashed potatoes are seasoned but not unusually loose. If yours already contain plenty of salt, taste a small amount before adding the measured salt. The recipe makes about eight pancakes, depending on how large you shape them.

Instructions

Mix the batter. Put the cold mashed potatoes in a bowl and break up any large lumps. Add the egg, ⅓ cup (40 g) flour, green onion, salt, and pepper. Stir until evenly combined. The mixture should be moist but firm enough to scoop and shape. If it feels sticky or slumps, mix in extra flour 1 tablespoon (8 g) at a time; stop as soon as it holds together. Too much flour can make the pancakes dense.
Shape the pancakes. Divide the mixture into eight portions. With lightly floured hands, shape each into a patty about ½ inch (1.3 cm) thick. Set them on a plate. If the mixture sticks, dust your hands lightly with flour rather than adding a large amount to the batter.
Heat the skillet. Set a large, heavy skillet over medium heat and add about 1 tablespoon (15 ml) oil. Give the oil a minute or two to heat; it should shimmer, not smoke. A properly heated pan helps the pancakes brown instead of absorbing excess oil.
Fry in batches. Carefully place four patties in the skillet, leaving space between them. Cook for 3–4 minutes on the first side, until the bottoms are deeply golden and the edges look set. Turn gently with a thin spatula and cook for another 3–4 minutes. Add the remaining oil and cook the second batch the same way. Adjust the heat if the outsides darken before the centers are hot.
Check and serve. The pancakes should be hot all the way through, with crisp exteriors and tender centers. Because they contain egg, USDA FSIS guidance for egg dishes is a safe minimum internal temperature of 160°F (71°C); check the center of a thicker pancake with a food thermometer if you are unsure. Serve promptly, or keep cooked pancakes warm while finishing the batch.

Tips

Start with cold potatoes. Chilled mashed potatoes are easier to shape and less likely to spread in the pan. If the leftovers are very soft, use the extra flour gradually or refrigerate the mixed batter for 10–15 minutes before shaping; that optional chill adds time to the total.
Check what is already in the mash. Butter, milk, cream, cheese, or roasted garlic are all fine, but very wet or heavily enriched potatoes may need a little more flour. Add only enough to make patties that hold their shape.
Flip once the crust has formed. Moving the pancakes too soon can tear them. Use a wide, thin spatula and turn them carefully after the underside is browned and releases from the skillet.
Make them gluten-free if needed. Substitute a cup-for-cup gluten-free flour blend for the all-purpose flour. The texture can vary by blend, so add it a spoonful at a time until the mixture is shapeable.

Serving Suggestions

Serve the pancakes hot with sour cream, plain yogurt, or applesauce. Chopped chives, green onion, or a little grated cheese make easy toppings. For a more filling meal, pair them with a crisp green salad, sautéed vegetables, or a bowl of soup. They also work alongside eggs or roasted meat as a savory potato side; keep in mind that a topping or accompaniment may change the meal’s overall cooking and food-safety needs.

Variations

For a cheesier version, fold ¼ cup (28 g) finely grated cheddar or Parmesan into the potato mixture. Add 1 tablespoon (about 3 g) chopped fresh parsley or dill for a fresh, savory note, or use a pinch of smoked paprika or garlic powder. For extra crisp edges, press the patties slightly thinner, about ⅜ inch (1 cm), and watch them closely because they may cook faster. You can also fold in ¼ cup (30 g) finely chopped cooked vegetables, such as broccoli or bell pepper, provided they are well drained; wet additions can make the patties difficult to turn.

Storage and Reheating

Refrigerate cooked pancakes within 2 hours of cooking, in a covered container, for 3–4 days. Cool them promptly rather than leaving them on the counter to reach room temperature. To freeze, arrange fully cooled pancakes in a single layer until firm, then transfer them to a freezer-safe container with parchment between layers; use within about 2 months for best texture. Thaw overnight in the refrigerator, or reheat from frozen.

For the crispest result, reheat in a lightly oiled skillet over medium-low heat, turning once, until hot through. An oven or toaster oven at 375°F (190°C) also works; warm on a baking sheet for about 8–12 minutes, adding a few minutes if frozen. Microwave reheating is quicker but softens the crust. Reheat leftovers to 165°F (74°C), as recommended by USDA FSIS, and avoid reheating the same portion repeatedly.

Frequently Asked Questions

Can I use mashed potatoes that have milk or butter in them?
Yes. Butter and milk in the original mash are suitable. If the potatoes are loose or creamy, add flour a tablespoon (8 g) at a time until the mixture can be shaped; rich potatoes may brown sooner, so keep the skillet at medium heat.

Why are my potato pancakes falling apart?
The mixture may be too wet, the patties may be too thick, or the first side may not have browned enough before turning. Mix in a little more flour, make even patties about ½ inch (1.3 cm) thick, and wait for a firm golden crust before flipping.

Can I make the mixture ahead?
You can mix it, cover the bowl, and refrigerate it for up to 24 hours, provided the mashed potatoes were handled safely and refrigerated promptly. The mixture may firm up as it chills. Shape and fry shortly before serving for the best crust.

Can I cook these in an air fryer?
Yes, though they may be less evenly browned than skillet-fried pancakes. Lightly brush or spray the patties with oil and cook in a single layer at 375°F (190°C), turning once, until crisp and hot through; timing varies by appliance and patty thickness. Check that the center reaches 160°F (71°C) for egg dishes.

Can I make potato pancakes without egg?
Egg helps bind the mixture, so an egg-free batch may be more delicate. Use a commercial egg replacer according to its package directions, or try 1 tablespoon (7 g) ground flaxseed mixed with 3 tablespoons (45 ml) water and rested for 5 minutes. Add flour as needed and turn the patties gently.

Are these the same as latkes?
They are related in shape and cooking method, but not identical. Many latkes are made from grated raw potatoes, while this recipe uses cooked mashed potatoes; both have regional and family variations, and the names are not interchangeable in every tradition.
