  • 2 cups mashed potatoes prepared
  • 1 cup flour divided, can use a gluten-free 1-to-1 blend
  • 1 large egg whisked
  • ½ cup cheddar cheese shredded
  • 2 Tbsp. green onions or chives finely chopped
  • ½ tsp. salt to taste
  • Pinch black pepper
  • 2-4 Tbsp. oil


  • Add the potatoes to a large bowl along with ½ cup of flour, cheese, egg, green onions or chives, salt, and black pepper. Mix this all together with a spatula until well combined. Depending on how thick or creamy your potatoes originally were, you may need to add a bit more flour. Add a couple of tablespoons at a time until you get to a consistency that is no longer completely sticking to your spatula.
  • Using a measuring cup, scoop out ¼-⅓ cup of the batter. Add it to a medium-sized shallow bowl that has 1/2 of a cup of flour in it. Sprinkle a bit of flour on top, pat the dough down a little, and then flip it over to completely coat it. Shake off any excess flour and shape it into a patty that is roughly 3-4 inches wide and ½-inch thick. Repeat this with the remaining batter until they’re all covered.
  • If you’d like to make a more perfectly round shape, place the patties on a plate and use the tip of a spatula to smooth up the edges and flatten the tops.
  • Place a large non-stick or ceramic skillet over medium heat along with 2 tablespoons of a mildly flavored oil such as avocado oil. Once sizzling, add 5-6 potato pancakes in a single layer, making sure none of them are touching.
  • Cook the pancakes for 4-5 minutes per side, or until they puff up slightly and turn a gorgeous golden color.
  • Serve the potato pancakes immediately with a dollop of sour cream and additional chopped green onions or chives. Enjoy!

  • To Store: Keep leftover potato pancakes in an airtight container in the refrigerator for up to 5 to 6 days.
  • To Freeze: Potato pancakes can be frozen tightly wrapped raw or cooked for up to 6 months.
  • To Reheat: Warm these pancakes back up in a skillet over medium heat for a few minutes.
