Notes

  • Talk about economical! This recipe uses leftover mashed potatoes and creates a whole new side dish, mashed potato cakes.  And it only is only 5 ingredients!
  • Granny's Leftover Mashed Potato Cakes are very basic.  The mashed potato base should already be flavorful, so we only add grated onion and bread crumbs to thicken it up.  
    • You could easily jazz up leftover potato pancakes in a hundred different ways. Try adding garlic powder, shredded cheese, chives, parsley or anything your heart desires.
  • To get onion juice, grate the onion.  This gives the flavor of onion without the texture.  Feel free to finely dice the onion or use 1 teaspoon onion powder.
  • Why do your potato cakes fall apart when frying?  If you start with a very creamy mashed potato, you'll need to add enough binder ingredients to hold them together.  The beaten egg and breadcrumbs act as the binder in our mashed potato cakes.  I recommend starting with 1 tablespoon of breadcrumbs and go up until the mashed potatoes are capable of forming into a ball.
  • Another reason the potato pancakes fall apart is because you are moving or flipping them too often.  Do not move, and only flip once.  You'll see the brown crust forming around the edge in the oil.  If you move them around, the crust will not form. 
  • Some old fashioned potato cakes use flour instead of breadcrumbs.  That is perfectly great.  Start with a couple tablespoons and work up if needed. 
  • Fry up the leftover potato cake in vegetable oil or butter. Your preference.
  • This leftover mashed potato pancake recipe starts with approximately 2 cups leftover mashed potatoes.  If you have more or less, adjust the egg, onion and breadcrumbs accordingly.
