Crispy Leftover Mashed Potato Pancakes
If you have leftover mashed potatoes sitting in the refrigerator, don’t reheat them and call it dinner. Turn them into these Crispy Leftover Mashed Potato Pancakes instead!
They’re golden and crunchy on the outside, soft and cheesy in the middle, and so incredibly comforting. A few simple ingredients transform yesterday’s mashed potatoes into something that tastes completely new.
I especially love making these after a big family dinner or holiday meal. There’s always a little container of mashed potatoes left over, and these pancakes are my favorite way to give them a second life.
The first time I made them, I wasn’t expecting everyone to get quite so excited. I put a plate of crispy potato pancakes on the table with sour cream and green onions, thinking we’d have some left for later.
We didn’t.
Everyone kept reaching for “just one more.”
That’s when I knew this was a leftover recipe worth keeping.

Ingredients
3 cups cold leftover mashed potatoes
1 large egg
½ cup shredded cheddar cheese
¼ cup all-purpose flour
2 green onions, finely sliced
2 tablespoons chopped fresh parsley
½ teaspoon garlic powder
½ teaspoon onion powder
¼ teaspoon black pepper
¼ teaspoon salt, or to taste

How to Make Crispy Leftover Mashed Potato Pancakes
1. Combine the Ingredients
Place the cold mashed potatoes in a large bowl.
Add the egg, cheddar cheese, flour, green onions, parsley, garlic powder, onion powder, black pepper, and salt.
Mix gently until everything is combined.
The mixture should be thick enough to shape into patties.
2. Check the Consistency
If your mashed potatoes are particularly soft or creamy, add another tablespoon of flour.
If they’re very firm, a tablespoon of milk or sour cream can loosen the mixture slightly.
Don’t make the mixture too wet.
A thicker mixture creates pancakes that hold their shape and develop a better crust.
3. Shape the Pancakes
Scoop out approximately ¼ cup of the mixture.
Shape it into a round patty about ½ inch thick.
Repeat with the remaining mixture.
For especially crispy pancakes, keep them relatively thin.
4. Heat the Pan
Heat a large skillet over medium heat.
Add the olive oil, butter, or a combination of both.
Once the fat is hot, carefully place the potato pancakes into the pan.
Don’t overcrowd the skillet.
5. Fry Until Golden
Cook for approximately 3–5 minutes per side, until the pancakes are deeply golden and crispy.
Don’t rush the flipping.
Let the first side develop a firm crust before turning them over.
6. Drain and Serve
Transfer the cooked pancakes to a paper-towel-lined plate or wire rack.
Serve immediately while they’re hot and crispy.

My Best Tips for Crispy Potato Pancakes
Start With Cold Mashed Potatoes
Cold potatoes are easier to shape and hold together better.
If your mashed potatoes are freshly made, refrigerate them first.
Don’t Make Them Too Thick
Thick patties can remain soft in the center while the outside becomes overly brown.
Around ½ inch thick is a great starting point.
Don’t Flip Too Soon
This is probably the biggest secret.
Once the pancake has developed a golden crust, it will release from the skillet much more easily.
Don’t Crowd the Pan
Give each pancake room.
Crowding lowers the temperature of the skillet and can prevent proper browning.
Use a Combination of Butter and Oil
Butter adds wonderful flavor, while oil helps increase the frying temperature and encourages browning.
Can I Add Bacon?
Absolutely!
Crispy bacon is one of my favorite additions.
Cook the bacon until crisp, crumble it, and fold it into the potato mixture.
You can also sprinkle a little extra bacon over the finished pancakes.
Can I Use Different Cheese?
Definitely.
Try:
Cheddar
Monterey Jack
Colby Jack
Pepper Jack
Mozzarella
Parmesan
Gruyère
Sharp cheddar gives the pancakes a particularly delicious flavor.
Can I Add Vegetables?
Yes.
Try adding:
Corn
Finely diced bell pepper
Sautéed mushrooms
Spinach
Shredded zucchini
Caramelized onions
Make sure watery vegetables are cooked and drained well before adding them.
Can I Add Fresh Herbs?
Absolutely.
Fresh chives, parsley, dill, thyme, and green onions all work beautifully.
For a holiday-style flavor, try parsley, sage, and thyme.
Can I Make These Gluten-Free?
Yes.
Replace the all-purpose flour with a gluten-free flour blend.
You can also experiment with almond flour, although the texture will be somewhat different.
Can I Make Them Without Eggs?
The egg helps bind everything together.
You can try a suitable egg substitute, but the pancakes may be more fragile.
If your mashed potatoes are already quite sticky, you may be able to form them with another binder such as shredded cheese and a small amount of flour.
Can I Bake Them Instead of Frying?
Yes.
Place the formed pancakes on a parchment-lined baking sheet.
Brush both sides lightly with oil and bake at 425°F (220°C) until golden, carefully flipping halfway through.
They won’t be quite as crisp as pan-fried pancakes, but they’ll still be delicious.
Can I Air Fry Them?
Absolutely.
Lightly spray both sides with oil and arrange the pancakes in a single layer.
Air fry at approximately 375°F (190°C) until golden and crisp, flipping halfway through.
Depending on your air fryer, this usually takes around 10–15 minutes.
What Can I Serve With Potato Pancakes?
There are so many possibilities.
For Breakfast
Serve with:
Fried eggs
Scrambled eggs
Bacon
Sausage
Avocado
For Lunch or Dinner
Pair them with:
Grilled chicken
Roast beef
Steak
Pork chops
Green salad
Roasted vegetables
Soup
For Dipping
Try:
Sour cream
Greek yogurt
Ranch dressing
Garlic aioli
Chive sour cream
Applesauce
Hot sauce
A dollop of sour cream and a sprinkle of fresh green onions is my favorite simple combination.
Can I Make Them Ahead?
Yes.
Shape the pancakes and place them on a parchment-lined tray.
Cover and refrigerate for several hours before cooking.
You can also cook them ahead and reheat them when you’re ready to serve.
How Do I Store Leftovers?
Place cooled pancakes in an airtight container and refrigerate for approximately 3–4 days.
How Do I Reheat Them?
For the crispiest result, reheat them in:
A skillet
An air fryer
A toaster oven
A conventional oven
Avoid the microwave if you want to preserve the crispy exterior.
Can I Freeze Potato Pancakes?
Yes.
Let the cooked pancakes cool completely.
Place them in a single layer on a baking sheet and freeze until firm.
Transfer them to a freezer-safe container or bag, placing parchment between layers if necessary.
Reheat from frozen in the oven or air fryer until hot and crisp.
What If My Potato Pancakes Fall Apart?
Your mixture may be too soft.
Add another tablespoon or two of flour or breadcrumbs.
You can also refrigerate the shaped patties for 15–30 minutes before frying.
This helps them firm up.
What If the Mixture Is Too Dry?
Add a small amount of:
Milk
Sour cream
Greek yogurt
Another beaten egg
Add just a little at a time.
Can I Use Mashed Sweet Potatoes?
Yes!
Sweet potato pancakes are delicious with a slightly different flavor profile.
Try adding cinnamon for a sweet version or cheddar and smoked paprika for a savory version.
Frequently Asked Questions
Why aren’t my potato pancakes crispy?
The skillet may not be hot enough, the patties may be too thick, or there may be too much moisture in the potato mixture.
Use cold mashed potatoes, keep the pancakes relatively thin, and fry them in a properly heated skillet.
Can I use instant mashed potatoes?
Yes.
Prepare them according to the package directions, allow them to cool completely, and use them just like homemade mashed potatoes.
Can I use mashed potatoes with gravy mixed in?
You can, but very wet mashed potatoes may require additional flour or breadcrumbs to help the pancakes hold together.
Can I make mini potato pancakes?
Absolutely.
Smaller pancakes are perfect for appetizers or brunch.
Reduce the cooking time slightly and watch them closely.
Can I make one large potato pancake?
Yes.
Press the mixture into a well-greased skillet and cook it like a giant potato cake.
Carefully flip it once the bottom is deeply golden.

Final Thoughts
These Crispy Leftover Mashed Potato Pancakes might be one of my favorite ways to turn leftovers into something everyone actually gets excited about.
There’s something so satisfying about taking a container of yesterday’s mashed potatoes and turning it into a plate of golden, crispy pancakes.
The outside gets wonderfully crunchy.
The inside stays soft and cheesy.
The green onions add freshness.
And the garlic and herbs make the whole kitchen smell incredible while they’re cooking.
I love serving them with a little bowl of sour cream for dipping, but they’re just as good alongside eggs for breakfast or a simple green salad for lunch.
And if you have leftover turkey, ham, or roast beef in the refrigerator, these pancakes are a fantastic side for that, too.
They’re especially perfect after a holiday meal when the refrigerator is full of little containers of leftovers and you don’t want to eat the exact same dinner again.
Instead, grab those mashed potatoes and give them a second life.
Sometimes leftovers don’t feel like leftovers at all.
Sometimes they become the best part of the meal.
And these crispy little potato pancakes are definitely proof of that. 🥔🧀✨
