Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

• 1 teaspoon olive oil
• 1 medium onion, finely diced
• 2 garlic cloves, minced
• 2 cups mashed potatoes
• 1¾ cups all-purpose flour
• 2 large eggs, lightly beaten
• 1 cup shredded cheddar cheese
• ½ cup chopped fresh parsley
• ¾ teaspoon salt
• ½ teaspoon black pepper
• Extra olive oil for frying

Directions

Heat 1 teaspoon olive oil in a skillet over medium heat. Add the diced onion and cook for about 5 minutes until soft and translucent. Stir in the minced garlic and cook for another 30 seconds. Remove from the heat and allow the mixture to cool slightly.

In a large mixing bowl, combine the mashed potatoes, cooked onion mixture, flour, eggs, cheddar cheese, parsley, salt, and black pepper. Stir until everything is fully combined and a thick mixture forms.

Place a non-stick skillet over medium-high heat and add a small amount of olive oil. Scoop spoonfuls of the potato mixture into the skillet and gently flatten each portion with a spatula.

Cook the potato cakes for about 3 minutes per side or until golden brown and crispy. Transfer the cooked cakes to a paper towel-lined plate to remove excess oil. Repeat with the remaining mixture, adding more oil as needed.

Serve warm with sour cream, yogurt sauce, extra cheese, or chopped green onions.

Variations

You can easily customize these potato cakes with different flavors and ingredients.

For a spicy version, add finely chopped jalapeños or a pinch of chili flakes to the mixture. If you enjoy herbs, try adding thyme, oregano, or chives for extra flavor.

You can also replace cheddar cheese with mozzarella, gouda, or parmesan. For extra texture and nutrition, mix in cooked broccoli, corn, spinach, or diced bell peppers.

Sweet potatoes can also be used instead of regular mashed potatoes for a slightly sweeter taste and colorful presentation.

Storage/Reheating

Store leftover potato cakes in an airtight container in the refrigerator for up to 3 days.

To reheat, place the cakes in a skillet over medium heat for a few minutes on each side until crispy again. You can also warm them in the oven at 375°F for about 10 minutes.

Avoid microwaving if possible, as it may soften the crispy exterior.

These potato cakes also freeze well. Place cooled cakes in a freezer-safe container and freeze for up to 2 months. Reheat directly from frozen in the oven until hot and crisp.
