Ingredients You'll Need
These ingredients are straightforward but crucial in creating the perfect texture and flavor for the cakes. Each component plays its part in balancing creaminess, binding, and that addictive golden crust that makes this dish unforgettable.
- 2 ½ cups cold mashed potatoes: Using cold potatoes helps the cakes hold their shape and get crispy when fried.
- 1 ½ cups grated cheddar cheese: Cheddar adds a rich, melty cheesiness that complements the potatoes beautifully.
- 2 large eggs: Eggs act as a natural binder to keep the cakes from falling apart during cooking.
- ½ cup flour (plus extra for breading): Flour gives the cakes structure and helps create a crisp coating.
- Neutral flavored oil: A light oil for frying that won’t overpower the delicate flavors of the cakes.
- Sour cream and sliced green onions (to top): These toppings add a tangy freshness and color that brighten up every bite.
How to Make Leftover Mashed Potato Cakes Recipe
Step 1: Mix Dough
In a roomy bowl, combine the cold mashed potatoes, grated cheddar cheese, and eggs. Stir them together gently until the mixture begins to meld. Gradually mix in the flour, adjusting as needed, until you achieve a soft dough that’s sticky but manageable—this ensures your cakes will hold together and stay tender inside.
Step 2: Form Cakes
Shape the dough into eight evenly sized balls, then press them down firmly to create patties. Pour a bit of flour into a shallow bowl and coat each patty completely, which not only prevents sticking but also helps them crisp up beautifully when fried.
Step 3: Fry
Heat a splash of neutral oil in a non-stick or cast iron skillet over medium heat—getting the pan hot is key. Once ready, place half of the potato cakes in the pan and let them cook undisturbed for about 3 to 4 minutes. You’ll notice the bottoms turn a gorgeous golden brown and develop a satisfying crunch. Flip carefully and cook the other side until it matches the same golden perfection. Repeat with the remaining cakes, adding more oil if needed.
Step 4: Serve
Serve these irresistible potato cakes piping hot with generous dollops of sour cream and a sprinkling of fresh green onions. The creaminess and zing of the toppings contrast beautifully with the crunchy, cheesy cakes, making every mouthful delightfully balanced.
How to Serve Leftover Mashed Potato Cakes Recipe
Garnishes
topping your potato cakes with sour cream and sliced green onions adds a burst of cool creaminess and a fresh bite that complements the warm, cheesy cakes perfectly. You can also try a sprinkle of smoked paprika or chopped parsley for a little extra color and flavor.
Side Dishes
These potato cakes shine as a side to lighter dishes like a crisp green salad or roasted vegetables. They also pair wonderfully with scrambled eggs or grilled chicken, adding comforting texture and richness to your meal.
Creative Ways to Present
Want to impress guests? Stack the cakes with layers of sautéed mushrooms or avocado slices, or serve them alongside a tangy tomato chutney. Miniature versions work great as appetizers for parties, especially when served with a variety of dipping sauces like garlic aioli or spicy mustard.
Make Ahead and Storage
Storing Leftovers
If you happen to have any leftover mashed potato cakes, keep them in an airtight container in the refrigerator where they’ll last for up to three days. This makes them a perfect quick snack or side if you want to save time later.
Freezing
You can freeze unbaked potato cakes by placing them on a tray lined with parchment paper and freezing until firm. Once solid, transfer them to a freezer-safe bag. When you’re ready, fry them straight from frozen, adding a minute or two to the cooking time to ensure they’re heated through.
Reheating
To bring leftover potato cakes back to life, reheat them in a skillet over medium heat to restore crispiness. Avoid the microwave if you want to keep that perfect golden crust; a skillet or oven does wonders in reviving their original charm.
FAQs
Can I use leftover mashed potatoes that have butter and milk in them?
Absolutely! The butter and milk in your mashed potatoes actually make the cakes richer and more flavorful. Just be mindful of how wet the mash is and adjust the flour accordingly to get the right dough consistency.
What type of cheese works best in this recipe?
Cheddar is classic for its melty texture and sharp flavor, but you can experiment with cheeses like mozzarella for stretchiness or gruyere for a nutty twist. Just make sure to use a cheese that melts well.
Can I bake the potato cakes instead of frying them?
Yes! To bake, place the cakes on a parchment-lined baking sheet, brush lightly with oil, and bake at 400°F (200°C) for about 20 minutes, flipping halfway through. The texture will be a bit different—less crispy but still delicious.
How do I keep the potato cakes from falling apart?
Using cold potatoes, adding enough flour to bind the mixture, and not overcrowding the pan when frying are all key steps. Also, handle your cakes gently when flipping to keep their shape intact.
Are these cakes suitable for vegetarians?
Yes, this Leftover Mashed Potato Cakes Recipe is vegetarian-friendly as it contains no meat or meat-derived products. Just double-check any toppings or sauces you pair with to keep them vegetarian too.

Ingredients
Potato Cake Mixture
- 2 ½ cups cold mashed potatoes
- 1 ½ cups grated cheddar cheese
- 2 large eggs
- ½ cup flour (plus more for breading)
For Frying and Serving
- Neutral flavored oil (such as vegetable or canola oil; amount as needed for frying)
- Sour cream (for topping)
- Sliced green onions (for topping)
Instructions
- Mix dough: In a large bowl, combine the cold mashed potatoes, grated cheddar cheese, and eggs. Gradually stir in the flour, adding a little more if necessary, until the mixture forms a soft and slightly sticky dough.
- Form cakes: Divide the dough into eight equal portions. Roll each portion into a ball, then gently press down to form patties about ¾ inch thick. Pour some flour into a separate bowl and coat each cake with flour to prevent stickiness.
- Fry: Heat a generous splash of neutral flavored oil in a medium-sized cast iron or non-stick frying pan over medium heat. When hot, add half of the potato cakes, cooking for 3-4 minutes on each side or until golden brown and crispy. Carefully flip to cook the other side. Remove and place on paper towels to drain excess oil. Repeat with remaining cakes.
- Serve: Plate the crispy mashed potato cakes and top with dollops of sour cream and sliced green onions. Serve immediately while warm.
Notes
- Use a neutral oil with a high smoke point for frying, such as vegetable, canola, or grapeseed oil.
- The dough should be soft but manageable; if too sticky, add a bit more flour gradually.
- Make sure the pan and oil are adequately heated before adding the cakes to achieve a crispy crust.
- These cakes are best eaten fresh but can be reheated in a skillet or air fryer for crispiness.
- For a vegetarian option, ensure vegetarian-friendly cheese and eggs are used.
