Equipment

  • 1 glass bowl
  • 1 saute pan

Ingredients

PANCAKES

  • 2 cups mashed potatoes cold
  • 1 large egg
  • ¼ cup flour* plus 2 tablespoons all-purpose flour divided
  • ½ shredded cheese* I used vegan cheese, but shredded mozzarella is fine or cheddar
  • ½ cup onion chopped (I used red onion)
  • 4-6 Tablespoons oil any mild flavored oil is fine

AIOLI SAUCE

  • 1 cup mayonnaise
  • 1 tablespoon fresh lemon zest from 1 large lemon
  • 1 tablespoon fresh chopped chive or onion
  • 1 clove garlic minced
  • ½ teaspoon Dijon mustard
  • salt to taste
  • pepper to taste

Instructions

  • POTATO PANCAKES
  • In a large bowl, add all of the ingredients.
  • Stir them all together to combine. Set aside and prep the sauce (if you’re using this sauce, if you’re not, go ahead and skip over to frying them in pan).
  • AIOLI SAUCE
  • In a medium bowl, add the sauce ingredients. Stir them all together and combine well. Taste and season with salt and pepper, as needed.Set out a medium bowl. Measure all the ingredients into the bowl.
  • Cover and refrigerate until ready to use.
  • Refrigerate for up to 1 week.
  • In a large bowl, mix all of the ingredients together until well combined.
  • The mixture should be thick and should hold its shape. If it’s not thick enough, add a tablespoon of flour at a time (depending on the consistency of your mashed potatoes)
  • COOK POTATO PANCAKES
  • Use an ice cream scoop or spoon, scoop out the mixture into 6 portions. Roll each portion into a ball and form it into patties or cakes which are about ½- inch in thickness.
  • Place remaining flour in a shallow dish and dredge each pancake lightly in flour; set aside.
  • Heat the oil in a large skillet (cast iron is great for this recipe if you have one) on medium heat. Make sure you use enough oil to coat the entire bottom of the pan (start with 4 tablespoons and if not enough, add a bit more).
  • Add the potato pancakes into the hot oil, three at a time, don't overcrowd the pan. Gently flatten with the back of a rubber spatula.
  • Cook the patties until bottom is browned and sides are set.
  • Carefully flip the pancakes and cook for another 3 to 4 minutes, until browned and cooked through.
  • When you flip, be sure that the entire spatula is under the pancake. If you use just the front of the spatula you’ll end up breaking the pancake as you flip it. You have to fully support the entire underside of the pancake to make a nice flip.
  • Repeat with the rest of the patties .
  • Serve immediately with the aioli sauce or sour cream (use your favorite dairy-free if you’re dairy-free).
  • These potato pancakes are best served hot. But they’re also still delicious warm.

Notes

  • Consistency: Leftover mashed potatoes vary. If the mixture is too dry, add another egg. If it’s too wet, add flour 1 tablespoon at a time.
  • Gluten-free or paleo: Use 1:1 gluten-free flour, or cassava flour 1:1 for paleo.
  • Dairy-free: Use dairy-free cheese shreds and vegan mayo or unsweetened dairy-free yogurt in the aioli.
  • Egg-free: Replace the egg with a flax egg (1 tablespoon ground flaxseed mixed with 3 tablespoons water).
  • Aioli: Add a couple of chopped anchovy fillets for extra flavor and skip the salt. Refrigerate up to 1 week.
  • Make ahead: Shape the patties up to 1 day ahead and refrigerate. Remove 10 minutes before frying.
  • Storage: Refrigerate cooked pancakes up to 2 to 3 days. Reheat on a baking sheet at 350°F for 8 to 10 minutes.
  • Freezing: Freeze in a single layer in a freezer bag or airtight container for up to 2 months.
