Nutrition Facts: servingSize 1 serving, calories 156 kcal, Carbohydrate 17 g, Protein 8 g, Fat 7 g, Saturated Fat 4 g, Cholesterol 60 mg, Sodium 214 mg, Fiber 2 g, Sugar 1 g

Ingredients:

  • 3 cups leftover mashed potatoes (plain is best, but garlic mashed potatoes work too!)
  • 1 1/2 cups shredded cheese (I like a combination of cheddar and mozzarella)
  • 1/2 cup whole wheat flour
  • 1/3 cup chopped green onions, plus more for garnish
  • 1/3 cup crumbled cooked bacon OR chopped ham
  • 3 eggs
  • 1 1/2 teaspoon garlic powder
  • 1 teaspoon dried parsley (or 2 teaspoons freshly chopped parsley, if you have it)
  • 1/4 teaspoon dried thyme (optional)
  • salt and pepper to taste (about 1/2 tsp salt for flavour, at least)
  • a small amount of vegetable oil for frying
  • sour cream for serving

Instruction:

  1. Add the leftover mashed potatoes to a large bowl. They shouldn’t be cold from the fridge if you can help it – let them stand at room temperature for 30 minutes before adding any other ingredients OR mash them up well again to break up the clumps with a warm potato masher.
  2. Add the cheese, flour, green onion, bacon or ham, eggs, garlic powder, thyme, and salt and pepper.
  3. Stir all the ingredients together very well until everything is fully incorporated and the mixture is smooth.
  4. Form the mixture into 12 patties about 1.5 centimetres thick.
  5. Heat a large non-stick skillet over medium heat and add a small amount of vegetable oil (around 1-2 teaspoons).
  6. Fry the patties in batches (don’t overcrowd your skillet!) for about 5 minutes per side or until golden brown and completely cooked through.
  7. Enjoy warm with a dollop of sour cream, some more sliced green onions, and some extra cheese, if desired.

Ingredients:

  • 6 strips bacon
  • 1/2 cup diced white onion (chopped (or ¼ cup green onion))
  • 2 cloves garlic (chopped)
  • 2 cups cold mashed potatoes
  • 1 cup shredded cheese (such as cheddar)
  • 1 teaspoon salt
  • ½ teaspoon pepper
  • 2 tablespoons fresh basil (chopped, or ½ teaspoon dried)
  • 2 tablespoon fresh parsley (chopped, or 1 2 teaspoons dried)
  • 2 eggs
  • ½ cup flour (*see note)
  • 4 tablespoon butter or margarine (for frying)

Instruction:

  1. In a large skillet, fry the bacon over medium heat until crispy. Drain on paper towels and, once cooled, crumble.
  2. Reserve 2 tablespoons of bacon in the frying pan. Cook the onion and garlic over medium heat until translucent. (If using green onion, no need to precook).
  3. In a medium bowl, combine crumbled bacon, mashed potatoes, cooked onion, shredded cheese, basil, parsley, eggs, salt & pepper. Mix well and add flour a bit at a time until the potato cakes hold together. You may not need all of the flour.
  4. Melt 1 tablespoon of butter (or leftover bacon fat) in a clean skillet over medium heat.
  5. Scoop about ¼ of a cup of the potato mixture and form it into a ball. Place it in the hot pan and flatten it with a spatula until it’s about ½ – ¾″ thick. Repeat with remaining potato cakes (cooking in batches if needed).
  6. Fry for about 3 to 4 minutes on each side, until the potato patties are golden brown and crisp.
  7. For best results, serve immediately, while hot and crispy.
  8. Top with green onions, sour cream or ketchup.

Ingredients:

  • Extra Virgin Olive Oil (for pan frying)
  • 3 cups chilled mashed potatoes, (already cooked and stored in the fridge)
  • 1/2 cup feta cheese, (crumbled, more for garnish)
  • 1/4 cup all-purpose flour
  • 3 scallions, (both white and green parts, chopped, plus more for garnish)
  • 1/4 cup chopped fresh parsley
  • 1 egg
  • 1/3 to 1/2 cup plain breadcrumbs

Instruction:

  1. Make the mashed potato mixture: In a big bowl, combine the mashed potatoes, feta, all-purpose flour, scallions, and parsley. Break the egg and add it to the bowl. Mix with a wooden spoon until everything is well incorporated.
  2. Prepare the breadcrumbs: Spread the breadcrumbs on a plate and set next to the bowl with the mashed potato mixture.
  3. Make the patties: Using a measuring cup (either a 1/4 cup or 1/3 cup, depending on the size of the patties you want), scoop a portion of the mashed potato mixture to fill the measuring cup. Form a ball between your hands, and then lightly flatten to make a 1/2-inch thick patty. Dredge the patty on both sides with the breadcrumbs and set it flat on a baking sheet. Repeat until the mashed potato mixture is finished.
  4. Fry the mashed potato patties: Set a large non-stick pan or skillet over medium-high heat. Add enough olive oil to the pan so it’s about 1/2-inch deep. When the oil shimmers, arrange the patties in the pan in one single layer (do this in batches, if needed). Cook on one side for about 2 to 3 minutes or until the bottom is crispy and golden brown, then turn over and cook the patties for another 2 to 3 minutes, again watching for the crisp and color on the other side.
  5. Using the spatula, remove the cooked mashed potato patties from the skillet and transfer them to a tray, lined with a paper towel to drain any excess oil.
  6. Transfer the mashed potato patties to a serving plate and garnish with a bit more feta cheese and scallions. Enjoy!
