Why You’ll Love This Recipe

I love this recipe because it transforms simple mashed potatoes into something completely different. The outside becomes crisp and golden in the skillet, while the center stays creamy, cheesy, and tender.

I also appreciate how quickly these potato cakes come together. When I already have leftover mashed potatoes in the refrigerator, I can prepare the mixture in minutes. I can also change the seasonings and add-ins depending on what I have available.

Ingredients

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

Mashed potatoes
Large egg
All-purpose flour
Shredded cheddar cheese
Green onions
Garlic powder
Salt
Black pepper
Vegetable oil or olive oil for frying
Sour cream for serving, optional
Fresh parsley for garnish, optional

Directions

I place the cold mashed potatoes in a large mixing bowl. I add the egg, flour, shredded cheddar cheese, sliced green onions, garlic powder, salt, and black pepper.
I stir everything together until I have a thick mixture that holds its shape. If my mashed potatoes are particularly soft, I add a little more flour until the mixture is easy to handle.
I scoop portions of the potato mixture and gently shape them into round patties. I flatten each one slightly so the cakes cook evenly.
I heat a thin layer of oil in a large skillet over medium heat.
Once the oil is hot, I carefully place the potato cakes in the skillet without overcrowding the pan.
I cook them for about 3 to 4 minutes on the first side, until the bottoms are crisp and golden brown.
I carefully flip each cake and cook for another 3 to 4 minutes, until the second side is golden and the center is heated through.
I transfer the cooked potato cakes to a paper towel-lined plate to remove excess oil.
I serve them warm, usually with sour cream, sliced green onions, or fresh parsley.

Variations

I sometimes replace cheddar with mozzarella, Parmesan, Monterey Jack, or another cheese that melts well. A combination of cheeses also works when I want a stronger flavor.

For extra vegetables, I add finely chopped bell peppers, corn, peas, grated carrots, or cooked spinach. I make sure any vegetables containing a lot of moisture are well drained before adding them.

When I want extra crunch, I lightly coat the shaped potato cakes in breadcrumbs before frying. This gives me an even crispier exterior while keeping the middle soft.

I can also add cooked and crumbled bacon, diced ham, or shredded cooked chicken for a heartier version. For extra seasoning, I sometimes mix in smoked paprika, onion powder, fresh chives, or a small pinch of cayenne pepper.

If I prefer not to pan-fry the cakes, I can bake them on a lightly greased baking sheet until golden, flipping them partway through cooking.

Storage/Reheating

I store leftover Mashed Potato Cakes in an airtight container in the refrigerator for up to 3 to 4 days. I separate layers with parchment paper when necessary to prevent the cakes from sticking together.

For reheating, I prefer using a skillet over medium-low heat or placing the cakes in a 375°F (190°C) oven until hot and crisp. An air fryer also works well and helps restore the crispy exterior. I can use a microwave when I need something quick, although the cakes will be softer.

I can also freeze cooked potato cakes. I let them cool completely, freeze them in a single layer until firm, and then transfer them to a freezer-safe container. I keep them frozen for up to 2 to 3 months and reheat them directly from frozen or after thawing overnight in the refrigerator.

FAQs

Why are my mashed potato cakes falling apart?

I usually find that potato cakes fall apart when the mixture contains too much moisture or not enough binding ingredients. I add a little extra flour when the mixture feels too soft, and I make sure the egg is thoroughly incorporated before shaping the cakes.

Can I make potato cakes with instant mashed potatoes?

Yes. I can use prepared instant mashed potatoes as long as they are thick enough to hold their shape. I let them cool completely before mixing in the remaining ingredients.

Can I make mashed potato cakes without flour?

Yes. I can replace all-purpose flour with alternatives such as cornstarch or a suitable gluten-free flour blend. I adjust the quantity as needed until the potato mixture is firm enough to shape.

How do I make mashed potato cakes crispy?

I make sure the skillet and oil are properly heated before adding the cakes. I also avoid overcrowding the pan and let the first side develop a golden crust before flipping. For even more crunch, I coat the cakes lightly in breadcrumbs.

What can I serve with mashed potato cakes?

I like serving them with sour cream, applesauce, eggs, salad, roasted vegetables, or grilled meat. I can also serve smaller potato cakes as an appetizer with a favorite dipping sauce.

Conclusion

Mashed Potato Cakes are an easy and delicious way I like to give leftover mashed potatoes a second life. With crispy golden edges, a soft center, and plenty of cheesy flavor, they turn a basic leftover into a satisfying dish.
