These leftover mashed potato pancakes turn cold mashed potatoes into crispy, cheesy patties with cheddar and chives. Chill them briefly, then pan-fry until golden for an easy breakfast, brunch, appetizer, or side dish.

Instructions
Add 500 g cold leftover mashed potatoes, 1 large egg, 60 g all-purpose flour, 1 tsp salt, 1 tsp freshly ground black pepper, 1 tsp garlic powder, 60 g grated cheddar cheese, and 3 tbsp minced fresh chives to a large mixing bowl. Mix until evenly combined.
Divide the mixture into even portions and gently shape each portion into a patty. Arrange the patties on a parchment-lined tray and refrigerate for 15 minutes to help them firm up.
Heat enough extra-virgin olive oil or neutral oil for pan-frying in a skillet over medium heat. Add the patties and cook for 3–4 minutes per side, until the leftover mashed potato pancakes are golden and crisp.
Transfer the pancakes to a serving plate and serve warm with sour cream.
Notes
Start with Cold Potatoes: I use mashed potatoes straight from the refrigerator because the firmer mixture is easier to shape and less likely to break in the skillet. Shape with Light Hands: Press the mixture only firmly enough to hold each patty together. Compacting it too much can make the centers denser. Keep the Heat at Medium: This gives the pancakes time to heat through while the surfaces become golden without browning too quickly. Grate the Cheddar Freshly: I prefer freshly grated cheddar because it blends into the potato mixture and melts smoothly as the pancakes cook.
