Ingredients You’ll Need
· 3 cups cold mashed potatoes
· 1 1/2 cups shredded sharp cheddar cheese
· 2 large eggs, lightly beaten
· 1/2 cup all-purpose flour (plus extra for dusting)
· 1/4 cup green onions or fresh chives, finely chopped
· 1 teaspoon garlic powder
· 1 teaspoon onion powder
· 1/2 teaspoon salt
· 1/2 teaspoon black pepper
· 1/4 cup unsalted butter (for frying)
· 2 tablespoons olive oil (for frying)
Optional add-ins: 1/4 cup cooked crumbled bacon, 1/4 cup diced ham, 1/2 teaspoon smoked paprika, 1/4 teaspoon cayenne pepper for heat, 1/2 cup shredded Parmesan cheese, 2 tablespoons sour cream for extra creaminess
Note: For a gluten-free version, use gluten-free all-purpose flour or almond flour. For a dairy-free option, use dairy-free cheese and plant-based butter. Cold mashed potatoes work best—warm potatoes are too soft and won’t hold their shape.
Step-by-Step Instructions
- Combine the Ingredients: In a large mixing bowl, combine the cold mashed potatoes, shredded cheddar cheese, beaten eggs, flour, chopped green onions, garlic powder, onion powder, salt, and black pepper. Mix until thoroughly combined into a thick, moldable mixture. If the mixture is too sticky, add a little more flour, one tablespoon at a time.
- Form the Potato Cakes: Divide the mixture into 8 equal portions. Roll each portion into a ball, then flatten it slightly into an oval or round patty, about 1/2-inch thick. Lightly dust each patty with a little extra flour to help them crisp up. This also prevents sticking.
- Heat the Skillet: Heat the butter and olive oil in a large skillet over medium heat until the butter is melted and sizzling. The combination of butter and oil gives the best flavor and prevents burning.
- Fry the Potato Cakes: Carefully place the potato cakes in the skillet in a single layer. Do not overcrowd the pan—work in batches if necessary. Crowding steams the cakes instead of frying them.
- Cook Until Golden: Fry for 3-4 minutes per side, until deeply golden brown and crispy on the outside. Resist the urge to flip too early—let them develop a good crust.
- Drain and Serve: Transfer the cooked potato cakes to a plate lined with paper towels to drain any excess grease. Serve hot as a side dish or appetizer.
Tips for the Best Crispy Cheesy Mashed Potato Cakes
· Use Cold Mashed Potatoes: Cold mashed potatoes hold their shape better than warm ones. If using fresh mashed potatoes, chill them in the refrigerator for at least 2 hours before making the cakes.
· Don’t Overmix: Mix the ingredients just until combined. Overmixing can make the potato cakes dense and gluey.
· Adjust Consistency: If the mixture is too wet, add more flour. If it’s too dry, add a splash of milk or another egg. The mixture should hold together when pressed.
· Dust with Flour: Lightly dusting the patties with flour before frying helps them develop a crispy golden crust.
· Use a Combination of Butter and Oil: Butter adds flavor while oil prevents burning. The combination creates the perfect frying medium.
· Don’t Overcrowd the Pan: Fry in batches to ensure even cooking and maximum crispiness.
· Serve Immediately: These potato cakes are best enjoyed hot and fresh from the skillet while the cheese is melty and the exterior is crispy.
Variations & Substitutions
· Bacon Cheddar Potato Cakes: Add 1/4 cup cooked crumbled bacon to the mixture.
· Loaded Baked Potato Cakes: Add bacon, sour cream, and extra cheese. Top with more sour cream and chives for serving.
· Spicy Potato Cakes: Add 1/4 teaspoon cayenne pepper or diced jalapeños for heat.
· Herb Potato Cakes: Add 2 tablespoons fresh chopped parsley, dill, or rosemary.
· Parmesan Potato Cakes: Use Parmesan cheese instead of cheddar and add 1 teaspoon Italian seasoning.
· Sweet Potato Cakes: Substitute half the mashed potatoes with mashed sweet potatoes for a sweeter twist.
Make-Ahead and Freezer Instructions
· Make-Ahead: Form the potato cakes and refrigerate for up to 24 hours before frying. This makes dinner prep quick and easy.
· Freezer Method: Arrange uncooked potato cakes in a single layer on a baking sheet and freeze until solid. Transfer to a freezer bag and freeze for up to 3 months. Cook from frozen, adding 2-3 minutes per side. You can also freeze cooked potato cakes—reheat in a 375°F oven or air fryer until crispy.
Frequently Asked Questions
Can I use fresh mashed potatoes instead of leftover?
Yes, but make sure they’re cold. Spread freshly made mashed potatoes on a baking sheet and refrigerate for at least 2 hours until firm. Cold potatoes hold their shape better and result in crispier cakes.
Why are my potato cakes falling apart?
This usually means the mixture is too wet or there isn’t enough binder. Add more flour or another egg to help bind the mixture. Also, make sure to press the patties firmly together when forming.
Can I bake these instead of frying?
Yes! Place the potato cakes on a greased baking sheet, brush with melted butter or olive oil, and bake at 400°F for 20-25 minutes, flipping halfway, until golden and crispy. They won’t be quite as crispy as fried, but still delicious.
Can I air fry these potato cakes?
Absolutely. Preheat the air fryer to 375°F. Spray the potato cakes with oil and air fry for 10-12 minutes, flipping halfway, until golden and crispy.
How do I store leftovers?
Store in an airtight container in the refrigerator for up to 4 days. Reheat in a skillet over medium heat, in the oven at 375°F, or in the air fryer to restore crispiness. Avoid microwaving, which makes them soggy.
Can I freeze these potato cakes?
Yes! Freeze uncooked or cooked potato cakes. For uncooked, freeze on a baking sheet until solid, then transfer to a freezer bag. Cook from frozen, adding a few minutes per side. For cooked, reheat in the oven or air fryer.
What can I serve with these potato cakes?
Serve with sour cream, applesauce, ranch dressing, or a dollop of Greek yogurt. They pair beautifully with eggs and bacon for breakfast, or as a side dish with roasted chicken, steak, or pork.
Are these potato cakes gluten-free?
They can be. Use gluten-free all-purpose flour or almond flour instead of regular flour. Ensure all other ingredients are gluten-free.
