What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without fuss. Most are pantry staples, and the fresh herbs bring that lovely lift you don’t want to miss.

• Leftover mashed potatoes (about 2 cups / 450g) – ideally chilled, so they hold together better
• All-purpose flour (1/4 cup / 30g) – helps bind the mixture (use almond flour for a gluten-free option)
• Egg (1 large, room temperature) – adds structure
• Fresh parsley (2 tablespoons, finely chopped) – adds bright herb flavor
• Fresh chives (1 tablespoon, chopped) – mild oniony note
• Fresh thyme (1 teaspoon, leaves only) – subtle earthiness
• Garlic powder (1/2 teaspoon) – optional but recommended for depth
• Salt and freshly ground black pepper – to taste
• Unsalted butter (2 tablespoons) – for frying, adds richness and crispiness
• Olive oil (1 tablespoon) – helps prevent burning during frying
• Grated sharp cheddar cheese (1/4 cup / 25g, optional) – for extra flavor and melty goodness

For best results, I recommend using homemade or good-quality leftover mashed potatoes that aren’t too watery. If your mash is super creamy, add a bit more flour to help the cakes hold their shape. And hey, if you want to swap out the herbs, fresh dill or basil also work wonders. Just keep them finely chopped so they blend seamlessly into the cakes.

Equipment Needed

• Large mixing bowl – to combine everything smoothly
• Non-stick skillet or cast-iron pan – essential for getting that perfect golden crust (I swear by my cast iron for even heat)
• Spatula – a sturdy one to flip the cakes without breaking them
• Measuring cups and spoons – for precise ingredient amounts
• Knife and cutting board – for chopping those fresh herbs
• Optional: Food scale for accuracy, especially if you like to be precise with your baking and cooking

If you don’t have a cast-iron pan, a heavy-bottomed skillet works just fine. Just be sure to keep the heat moderate to avoid burning the butter. And if your spatula isn’t quite sturdy enough, a thin metal spatula can help you flip confidently without the cakes falling apart.

Preparation Method

1. Prepare the potato mixture: In a large bowl, place 2 cups (450g) of chilled leftover mashed potatoes. If your mash is lumpy, give it a gentle mash to smooth out larger chunks. Add 1 large room-temperature egg and 1/4 cup (30g) all-purpose flour. Mix until combined but don’t overwork it—this keeps the cakes tender.
2. Add the herbs and seasoning: Stir in 2 tablespoons finely chopped fresh parsley, 1 tablespoon chopped chives, and 1 teaspoon fresh thyme leaves. Add 1/2 teaspoon garlic powder, plus salt and freshly ground black pepper to taste. If using, fold in 1/4 cup (25g) grated sharp cheddar cheese now for a melty surprise inside.
3. Form the cakes: Lightly flour your hands and shape the mixture into 6 to 8 evenly sized patties, about 3 inches (7.5 cm) in diameter and 1/2 inch (1.25 cm) thick. Don’t pack too tightly; a little air keeps them from being dense.
4. Heat the pan: Place a non-stick or cast-iron skillet over medium heat. Add 2 tablespoons unsalted butter and 1 tablespoon olive oil. Let the butter melt and foam but not brown (about 2 minutes).
5. Cook the cakes: Carefully place the patties in the hot pan, leaving space in between. Cook for 4 to 5 minutes on the first side without moving them—this helps form a crispy crust. Flip gently and cook another 3 to 4 minutes until the other side is golden and crisp. If your heat is too high, the cakes might brown too fast before heating through—adjust accordingly.
6. Drain and serve: Transfer the cooked cakes to a paper towel-lined plate to drain excess oil. Serve warm with a dollop of sour cream, your favorite dipping sauce, or simply as is with a sprinkle of extra fresh herbs.

Pro tip: If the mixture feels too wet, add a tablespoon of flour at a time until it firms up enough to shape. Also, don’t rush the cooking; patience yields the crispiest, most satisfying crust. And yes, I’ve definitely flipped a few cakes too early in my time—lesson learned!

Cooking Tips & Techniques

To nail these crispy leftover mashed potato cakes every time, a few tricks go a long way. First, chilled mashed potatoes are your friend. They hold together better and prevent the cakes from falling apart during cooking. If your mash is freshly made and still warm, pop it in the fridge for at least an hour before starting.

When frying, medium heat is the sweet spot. Too hot and the cakes burn outside while staying cold inside; too low and they won’t get that golden crust. I like to use a combo of butter and olive oil—the butter adds flavor and richness, while the oil raises the smoke point to keep things from burning. Don’t overcrowd the pan either; give each cake room to crisp up nicely.

Another tip: use a thin, sturdy spatula to flip the cakes gently. Pressing down on them is tempting for extra crispness but avoid it—you’ll squeeze out moisture and end up with dense cakes. Let the heat and fat do the work.

Lastly, if you want to keep them warm for serving, place the cooked cakes on a baking sheet in a 200°F (95°C) oven. This keeps them crispy without overcooking while you finish the batch. Trust me, this little step makes a big difference when feeding hungry guests.

Variations & Adaptations

If you’re feeling adventurous or need to tweak the recipe for dietary reasons, here are a few ways to switch it up:

• Gluten-Free: Swap the all-purpose flour for almond flour or a gluten-free blend. The texture gets a bit nuttier but still holds up well.
• Vegan Version: Use flax egg (1 tablespoon ground flaxseed mixed with 3 tablespoons water) instead of a real egg, and fry in olive oil or vegan butter. Skip the cheese or use a plant-based alternative.
• Cheesy Herb Mix: Add a mix of Parmesan and mozzarella with your fresh herbs for a richer, melty cake.
• Spicy Kick: Stir in 1/4 teaspoon smoked paprika or cayenne pepper for a subtle heat that wakes up the flavor.
• Seasonal Twist: In spring, swap in fresh dill and lemon zest instead of thyme. Come fall, try sage and a pinch of nutmeg for that cozy vibe.

One of my favorite personal twists is adding a handful of sautéed mushrooms or caramelized onions to the mash before shaping—adds a lovely umami surprise. Just remember to drain any excess moisture from additions so your cakes stay crispy!

Serving & Storage Suggestions

These crispy leftover mashed potato cakes are best served hot from the pan, with a sprinkle of fresh herbs on top. They pair beautifully with a simple green salad for a light meal or alongside fried eggs for a cozy brunch. Honestly, a dollop of sour cream or your favorite hot sauce takes them to the next level.

If you have leftovers (good luck!), store them in an airtight container in the refrigerator for up to 3 days. For longer storage, freeze them on a baking tray first, then transfer to a freezer-safe bag for up to 2 months. When ready to eat, reheat in a skillet over medium heat to regain crispiness—microwaving tends to make them soggy, so avoid that if you can.

Fun fact: letting the cakes rest wrapped in foil for 10 minutes after cooking helps the flavors meld and the texture settle—kind of like a little flavor power nap.
