Servings 10 patties


  • 2 cups cold mashed potatoes (leftovers, packaged, or pre-made)
  • 1 egg
  • 1 cup cheddar cheese shredded
  • 1 tablespoon Worcestershire sauce*
  • ½ large white onion diced
  • ¼ cup green onion chopped, plus more for garnish
  • 2 garlic cloves minced
  • ½ cup flour**
  • 2 tablespoon fresh basil*** (optional) chopped
  • 2 tbsp fresh parsley*** chopped
  • 1 teaspoon salt
  • ½ teaspoon black pepper


  • In a large bowl, mix all ingredients (EXCEPT white onion, garlic, and butter) until everything is well-incorporated.
  • In a large pan, sautee your white onion and garlic with a bit of olive oil or butter for about five minutes, or until soft and fragrant. Remove from pan and add to the potato mixture.
  • Melt 1 tbsp. of butter in your pan on medium heat.
  • Take about ¼ cup of potato dough (it's sticky!) for each patty, and work into a ball shape.
  • Put 3 or 4 patties into the hot pan, and flatten with a spatula until they're about ½-inch to ¾-inch thick. Then cook on each side for about four minutes until they're golden and beginning to get a bit crispy. Repeat until all of your mashed potato batter is used up.
  • Serve with sour cream and extra green onion (or top with hot sauce or ketchup - the options are endless!) or grab one and eat it cold out of the refrigerator the next day -- they keep really well in the fridge for a few days!


*I use a generic brand that doesn't have anchovies in it **This amount of flour was perfect for mine, but if your dough seems way too runny, you can try adding a bit more flour ***If using dried parsley and basil, use about half as much
