Ingredients for Mashed Potato Cakes

Mashed Potatoes – Use leftover mashed potatoes if you have some or use instant mashed potatoes (or pre-made) if you don’t have any. Even cauliflower mashed potatoes can be used for a low-carb recipe.

Cheese – Experiment with different types of cheese, such as cheddar, parmesan cheese, Mexican blend, or pizza mozzarella.

Bacon – Bacon and mashed potatoes go hand in hand. Bacon can be oven baked or use real bacon bits.

Leftovers – As a variation, you can add leftovers like chopped chicken or turkey, leftover roasted veggies, etc.

Seasonings – Green onions are a favorite, add in other fresh herbs if you have them.

Prep Time 10 minutes

Cook Time 10 minutes

Total Time 20 minutes

  • 6 strips bacon
  • ½ 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
  • In a large skillet, fry the bacon over medium heat until crispy. Drain on paper towels and, once cooled, crumble.

  • 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).

  • 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.

  • Melt 1 tablespoon of butter (or leftover bacon fat) in a clean skillet over medium heat.

  • 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).

  • Fry for about 3 to 4 minutes on each side, until the potato patties are golden brown and crisp.

  • For best results, serve immediately, while hot and crispy.

  • Top with green onions, sour cream or ketchup.

Flour – Depending on the consistency of your potatoes, you may need a little bit less flour (or a little bit more). You want the cakes to stick together (and not be too sticky). 

Air Fryer – Potato cakes can be cooked in an air fryer. Form into patties and brush with melted butter. Cook at 400°F for about 12 minutes, turning after 6 minutes.
