Quick Skillet Mashed Potato Cakes are the perfect way to use up leftover mashed potatoes from last night’s dinner. I’m always happy when I have extra mashed potatoes in the fridge because it means I can make these crispy, golden patties the next day.
They’re crispy on the outside and soft on the inside, and they come together in about 23 minutes.
This recipe uses simple ingredients you probably already have: mashed potatoes, an egg, dried parsley, and a little grated onion.
You mix everything together, shape it into patties, coat them in flour, and pan-fry them in butter until they’re golden brown. The result is a side dish that works with almost any main course, from chicken to steak to pork chops.
A medium bowl and a skillet are all you need to make this recipe. These potato cakes are kid-friendly, which means you don’t have to make separate meals for picky eaters.
They’re also great for using up leftovers so nothing goes to waste. If you’re tired of reheating the same mashed potatoes over and over, this recipe gives you a completely different way to enjoy them.

Notes
Tips and Tricks
Chill the Potatoes – Cold mashed potatoes hold their shape better than warm ones. Make sure your leftovers are fully chilled before you start. Don’t Skip the Flour Coating – The flour creates a crispy crust on the outside. Press each patty firmly into the flour so it sticks. Use Low to Medium Heat – Cooking the patties slowly helps them get crispy without burning. If the heat is too high, the outside will burn before the inside warms through. Add Cheese for Extra Flavor – Mix ¼ cup of shredded cheddar cheese into the potato mixture before forming the patties. Make Them Smaller for Appetizers – Form smaller patties to serve as finger food or appetizers at parties. Freeze for Later – Shape the patties and freeze them on a baking sheet. Once frozen, transfer them to a freezer bag. Cook directly from frozen, adding a few extra minutes to the cooking time. Reheat in the Oven – Place leftover potato cakes on a baking sheet and warm them in a 350°F oven for about 10 minutes to restore their crispiness.Nutrition
