Step-by-Step Instructions
Let’s make this happen. These cheesy mashed potato cakes come together in just a few simple steps, and the smell of them frying up will have everyone circling the kitchen.
Place the potato chunks in a large pot and cover completely with cold water. Add a generous pinch of salt, set the pot on the stove, and bring everything to a rolling boil over high heat.
Cook the potatoes until they’re fork-tender and break apart easily, about 12 to 15 minutes. You want them soft enough to mash smoothly but not waterlogged.
Drain the potatoes very well in a colander, shaking off any excess water. Return them to the pot and mash with butter until the mixture is smooth, fluffy, and completely dry.
Let the mashed potatoes cool to room temperature so they’re no longer warm to the touch. Popping them in the fridge for 10 minutes helps firm everything up and makes shaping easier.
Add the egg, shredded cheddar cheese, minced garlic, chopped green onion, salt, and black pepper to the cooled mashed potatoes. Mix everything together until evenly combined and you can see little flecks of cheese and green onion throughout.
Taste the mixture and adjust the seasoning if needed. This is your chance to make sure the flavor is exactly where you want it.
Divide the potato mixture into 8 equal portions, each weighing about 100 grams if you’re using a scale. Roll each portion into a ball, then gently flatten it into a cake about 1½ inches thick.
Lightly coat each potato cake in cornstarch, making sure all sides are covered, then shake off any excess. This coating is what gives you that irresistible golden crust.
Heat the vegetable oil in a large skillet over medium heat until it shimmers but doesn’t smoke. Carefully place the potato cakes in the hot oil, leaving a little space between each one so they don’t crowd.
Fry the cakes for 2 to 3 minutes per side, flipping gently with a spatula, until they’re golden brown and crispy on both sides. The crust should be crunchy and the inside warm and creamy.
Transfer the finished cakes to a plate lined with paper towels to drain any excess oil, then serve them hot while they’re still crispy.
Expert Tips
Crispy potato cakes are all about getting the texture just right. A few small tweaks can take these from good to absolutely irresistible.
Use starchy potatoes like Russets or Yukon Golds for the fluffiest, most mashable texture. Waxy potatoes won’t give you the same creamy interior.
Make sure your mashed potatoes are as dry as possible after draining. Excess moisture makes the cakes fall apart and prevents them from getting crispy.
Chilling the mixture in the fridge for 10 to 15 minutes before shaping makes the cakes much easier to handle and helps them hold their shape in the pan.
Don’t skip the cornstarch coating. It’s the secret to that golden, crunchy crust that contrasts so beautifully with the creamy interior.
Keep your skillet at medium heat so the cakes have time to crisp up without burning. If the oil is too hot, the outside will brown before the inside warms through.
For even more flavor, try mixing in a tablespoon of fresh herbs like parsley, chives, or dill. According to Bon Appétit’s guide to perfect mashed potatoes, fresh herbs add brightness and depth to any potato dish.
Variations
These cheesy mashed potato cakes are endlessly adaptable. Swap in your favorite cheese, add different herbs, or toss in some crispy bacon for a whole new experience.
Try using Gruyère, Monterey Jack, or pepper jack cheese instead of cheddar for a different flavor profile. Smoked gouda adds a rich, smoky depth that’s absolutely delicious.
Stir in ¼ cup of cooked, crumbled bacon or diced ham for a heartier, more savory cake. The salty, smoky bits add incredible texture and flavor.
Add a tablespoon of fresh herbs like parsley, dill, or chives to brighten up the flavor. Fresh herbs make everything taste lighter and more vibrant.
For a spicy kick, mix in a diced jalapeño or a pinch of cayenne pepper. The heat pairs beautifully with the creamy potatoes and sharp cheese.
Make mini potato cakes by dividing the mixture into 16 smaller portions. These bite-sized versions are perfect for appetizers or snacking.
Troubleshooting
Problem: The potato cakes are falling apart in the pan.
Solution: Your mashed potatoes may have been too wet or warm when you mixed in the egg. Make sure they’re completely cool and dry, and chill the shaped cakes in the fridge for 15 minutes before frying.
Problem: The cakes are browning too fast on the outside but still cold inside.
Solution: Lower the heat to medium or medium-low. You want a gentle sizzle, not a roaring fry, so the cakes have time to warm through while the crust crisps up.
Problem: The coating isn’t sticking to the cakes.
Solution: Pat the cakes dry before dusting them with cornstarch, and press the coating gently into the surface. A light mist of water can help the cornstarch adhere if needed.
Problem: The cakes taste bland.
Solution: Taste your potato mixture before shaping and adjust the salt, pepper, and garlic. Don’t be shy with seasoning — potatoes need a generous hand.
Storage & Reheating
Crispy potato cakes are best enjoyed fresh and hot, but they store and reheat beautifully if you have leftovers. Serve them with sour cream, hot sauce, or a dollop of Greek yogurt for dipping.
Store cooled potato cakes in an airtight container in the refrigerator for up to 3 days. Layer them between sheets of parchment paper to prevent sticking.
To reheat, place the cakes on a baking sheet and warm them in a 375°F oven for 10 to 12 minutes until crispy and heated through. You can also reheat them in a skillet with a little oil for extra crispness.
| Storage Method | Duration | Best For |
|---|---|---|
| Room temperature | 2 hours max | Serving immediately |
| Refrigerator | Up to 3 days | Make-ahead batches |
| Freezer (uncooked) | Up to 2 months | Meal prep and planning |
| Freezer (cooked) | Up to 1 month | Quick reheating |
No-Waste Kitchen Ideas
Got leftover ingredients or potato cakes? Here’s how to use every last bit without any waste.
Save your potato peels and roast them with olive oil, salt, and paprika for crispy snacks. They’re delicious and packed with fiber. Use leftover green onion tops in scrambled eggs, soups, or as a garnish for just about anything savory. The green parts are just as flavorful as the white.
Crumble any broken or extra potato cakes over a salad for a crunchy, savory topping. They add texture and turn a simple salad into a full meal. Freeze uncooked potato cakes on a baking sheet until solid, then transfer them to a freezer bag. Fry them straight from frozen whenever you need a quick side dish.
Turn leftover cheddar cheese into a quick cheese sauce by melting it with a splash of milk. Drizzle it over the cakes or use it as a dip.
