Ingredients You'll Need

The magic of this recipe lies in its simplicity. Each ingredient plays a crucial role in building flavor, texture, or color to create the perfect potato cakes. From eggs to Parmesan, and a touch of fresh chives, everything works together in harmony to elevate those leftover mashed potatoes.

• Large egg: Acts as a binder to hold the cakes together without making them heavy.
• Garlic cloves (minced): Adds a warm, fragrant punch that makes the flavor pop.
• Leftover mashed potatoes (chilled): The star of the show, providing creamy softness inside the crispy cakes.
• All-purpose flour (divided): Helps give structure and a lightly crispy coating when dredged.
• Grated Parmesan cheese: Adds a nutty, salty richness that elevates the overall taste.
• Thinly sliced chives or green onions: Bring a fresh, oniony brightness and pretty green flecks to the cakes.
• Vegetable oil (for frying): Creates a golden-brown crust that’s irresistibly crunchy.
• Kosher salt: Enhances all the flavors and finishes the dish perfectly.
• Sour cream (optional, for serving): A cool, tangy dollop that complements the warm, savory cakes beautifully.

Directions

Step 1: In a large bowl, whisk the egg until smooth. Add the minced garlic, chilled mashed potatoes, ¼ cup of the flour, grated Parmesan cheese, and sliced chives. Stir everything together with a fork until well combined, then cover and transfer the mixture to the refrigerator to chill for 20 minutes. This step helps the mixture firm up, making it easier to handle later.

Step 2: Spread the remaining ¼ cup of flour on a small plate. Divide the potato mixture into 8 equal portions. Using your lightly floured hands, shape each portion into a ball first, then gently flatten it into a cake about 3 inches in diameter and ½-inch thick. Lightly coat both sides of each cake in the flour. This light dredging ensures a crisp crust while frying.

Step 3: Heat the vegetable oil on a large nonstick griddle or skillet over medium heat. Carefully transfer the potato cakes to the hot oil and cook for 6 to 8 minutes total, flipping once halfway through, until both sides are golden brown and the cakes are warmed through. Sprinkle the cakes with kosher salt immediately after cooking for that perfect finishing touch. If your pan is small, cook in batches and keep cooked cakes warm in a 200-degree Fahrenheit oven on a rimmed baking sheet until ready to serve.

Step 4: Serve the potato cakes warm, garnished with a dollop of sour cream and extra sliced chives if you like. They are best enjoyed right away while the edges remain perfectly crisp and the insides are soft and flavorful.

Servings and Timing

This Potato Cakes from Mashed Potatoes Recipe makes about 4 servings, with each person enjoying two delicious cakes. Prep time will take you roughly 10 minutes, plus 20 minutes of chilling time to help the mixture set properly. Cooking time is about 10 minutes, making the total time around 40 to 45 minutes. No additional resting or cooling time is needed after cooking, but serving them fresh and warm really highlights the crispy texture and balanced flavors.

How to Serve This Potato Cakes from Mashed Potatoes Recipe

When it comes to serving these potato cakes, I love pairing them with a bright, fresh salad—think mixed greens with a simple lemon vinaigrette. The acidity cuts through the richness of the cakes nicely and keeps the meal light and balanced. Roasted vegetables or a tangy cucumber and tomato salad also make wonderful, colorful companions.

For garnishing, I often go for a spoonful of sour cream on top of each cake, sprinkled with extra chives or green onions for a pop of color and fresh bite. Presentation-wise, stacking two cakes per plate and adding a side of the salad is my go-to for casual dinners, but you can also serve them individually as appetizers for parties or brunches.

These cakes are fantastic served warm or at room temperature. I find that they maintain their flavors beautifully and stay crisp if kept warm in the oven just before serving. For drinks, I usually reach for sparkling water with a squeeze of fresh lemon or a refreshing iced herbal tea, which pairs perfectly without overpowering the savory flavors of the dish.

Variations

I enjoy experimenting with this potato cakes recipe to suit different tastes and needs. If you want to make it gluten-free, simply swap the all-purpose flour for a gluten-free all-purpose blend or even a bit of cornstarch to maintain crispiness. For a dairy-free option, I've found that leaving out the Parmesan cheese or substituting it with nutritional yeast still delivers a nice savory note.

Flavor-wise, adding chopped fresh herbs like parsley, dill, or even a bit of thyme switches up the profile and adds complexity. If you prefer a bit of heat, mixing in a pinch of red pepper flakes or diced jalapeños into the potato mixture gives the cakes a lively kick. You can also try baking the cakes in a lightly oiled skillet in the oven if you want to avoid frying, although the texture will be less crispy but still delicious.

Storage and Reheating

Storing Leftovers

If you happen to have leftovers, I recommend storing them in an airtight container in the refrigerator. They keep well for up to 3 days. I find that placing parchment paper between each cake helps prevent them from sticking together. Just be sure to let the cakes cool completely at room temperature before sealing to avoid condensation inside the container.

Freezing

This recipe freezes quite well! To freeze, arrange the cooled potato cakes in a single layer on a baking sheet and flash freeze until solid. Then transfer them to a freezer-safe bag or container with parchment paper between layers. They keep best for up to 2 months this way. When you’re ready to enjoy them, thaw in the refrigerator overnight for the best texture.

Reheating

The best way to reheat these potato cakes and preserve their crispiness is to warm them in a lightly oiled skillet over medium heat for a few minutes on each side. Avoid microwaving if you can, as this tends to make the cakes soggy. If using an oven, heat at 350 degrees Fahrenheit on a baking sheet for about 10 minutes until warmed through and crispy again. This brings back that irresistible crust and soft interior everyone loves.

FAQs

Can I use fresh mashed potatoes instead of leftovers?

Absolutely! You can use freshly made mashed potatoes as long as they are chilled. Make sure they aren’t too hot or runny, or the cakes may not hold their shape well. Chilling the potatoes for at least an hour before mixing helps achieve the perfect consistency.

What if I don’t have Parmesan cheese—is there a substitute?

If you don’t have Parmesan, you can use another hard cheese like Pecorino Romano or a mild cheddar. For a dairy-free version, nutritional yeast adds a nice cheesy flavor without the dairy. Just keep in mind that Parmesan’s saltiness and nuttiness gives the recipe its signature taste.

Can I make these potato cakes vegan?

Yes! To make a vegan version, skip the egg and cheese and replace the egg with a flax egg (1 tablespoon ground flaxseed mixed with 3 tablespoons water, chilled). Use nutritional yeast for cheesy flavor and be sure to fry in plant-based oil. The texture will be a little different but still delicious.

How do I prevent the potato cakes from falling apart when cooking?

Ensuring the mixture is well chilled before shaping and frying is key to holding the cakes together. Don’t skimp on the flour or the egg, as they act as binders. Also, resist the urge to flip the cakes too often—let them cook undisturbed until golden on one side, then flip gently.

Can I add other ingredients like vegetables or bacon to this recipe?

You can definitely personalize the recipe! Chopped cooked vegetables like spinach, corn, or bell peppers can be stirred into the mixture before shaping. If avoiding pork, try cooked turkey bacon or smoked paprika for a smoky flavor. Just make sure any additions are finely chopped and don’t add too much moisture.

Conclusion

I genuinely can’t recommend this Potato Cakes from Mashed Potatoes Recipe enough. It’s such a smart way to refresh leftovers into something that feels special and satisfying. Whether you’re making a cozy weeknight dinner or feeding a handful of friends, these cakes are always a hit. Give it a try, and I promise you’ll be reaching for this recipe again and again!
