This recipe transforms leftover cold mashed potatoes into savory, crispy cakes. Infused with fresh scallions and finely ribboned kale, bound with egg and bread crumbs, these patties are pan-fried until golden brown. They offer a delightful way to repurpose leftovers into a flavorful main course or side dish, perfect for a hearty vegetarian meal.
Ensure your mashed potatoes are well-chilled; this is crucial for the cakes to hold their shape during mixing and cooking. For optimal crispness and flavor, don't overcrowd the skillet; cook in batches if necessary. A mix of olive and vegetable oil provides a balance of flavor and a higher smoke point for even browning. Season generously but taste first if your mashed potatoes are already seasoned. For an elevated touch, serve with a dollop of crème fraîche or a quick lemon-herb aioli. A sprinkle of Parmesan cheese in the mix would also add a lovely savory depth.
