Crispy Mashed Potato Fries
Golden, crispy mashed potato fries with soft, fluffy centres. An irresistible homemade appetizer or side dish!
I’ve been seeing versions of crispy mashed potato fries all over YouTube, so of course I had to give them a try. And yes, they’re definitely an easy winner! Made with simple russet potatoes, these golden potato fries come out crisp on the outside, soft and fluffy in the middle, and are finished with a good sprinkle of salt and pepper. Fair warning though — these are best eaten piping hot straight from the skillet. No leftovers allowed!
Golden, Crispy Mashed Potato Fries with Fluffy Centres
These homemade mashed potato fries take ordinary russet potatoes and turn them into something seriously delicious. The potatoes are mashed, shaped into thick fries and pan-fried until beautifully golden. The outside gets wonderfully crispy while the middle stays soft and fluffy. Just add a little salt and pepper, and they’re ready to enjoy.
Why You’ll Love These Homemade Potato Fries
It’s that crispy outside and soft mashed potato centre that makes these fries so good. You only need a handful of simple ingredients, and a little cornstarch helps everything hold together. Don’t worry about making every fry perfectly straight. The slightly rustic ones taste just as good, especially when those golden edges start to crisp up in the pan.
The Perfect Crispy Potato Snack or Easy Side Dish
Serve these crispy mashed potato fries alongside juicy burgers, grilled chicken or your favourite sandwiches. They’re also a fun weekend appetizer with garlic aioli, spicy mayo or classic ketchup for dipping. They’re great for casual family dinners or sharing with friends. Just make sure everyone is ready to eat because they’re at their absolute best hot from the frying pan.
How to Make Crispy Mashed Potato Fries
Prepare and Mash the Russet Potatoes
Start by peeling and cutting the russet potatoes into even chunks so they cook at roughly the same rate. Boil until completely fork-tender, then drain them really well before mashing. For the best crispy mashed potato fries, you want the potatoes smooth and fairly dry — extra water can make the mixture sticky and harder to shape. A few tiny potato bits are fine; they don’t have to look perfectly whipped.
Real Kitchen Tip: The Secret to Crispy Mashed Potato Fries
Let your mashed potatoes cool before mixing in the cornstarch and shaping your fries. Warm potatoes can make the mixture too soft and sticky to handle. Try to keep the fries roughly the same thickness so they cook evenly, and avoid overcrowding the pan. Give them time to develop a golden, crispy crust before turning. That little bit of patience makes all the difference!
Shape the Mashed Potato Fries
Once the potato mixture is cool enough to handle, divide it into small portions and gently roll each one into a long French fry shape. Keep them fairly even in thickness so the mashed potato fries cook evenly and develop a crisp golden outside. They don’t need to look perfect — mine were a little rustic, and that’s part of the charm. Just handle them gently so they hold together before frying.
Pan-Fry Until Golden and Crispy
Heat a thin layer of oil in a non-stick frying pan over medium heat, then add the mashed potato fries in a single layer. Let them cook undisturbed for a couple of minutes before turning — this gives the outside time to form that golden, crispy crust. Turn gently with tongs or chopsticks and keep cooking until all sides are evenly browned. Finish with a sprinkle of salt and pepper and serve right away while the centres are still soft and fluffy.
Tips and Tricks for Perfectly Crispy Mashed Potato Fries
- Choose russet potatoes. Their fluffy texture makes them ideal for homemade mashed potato fries with soft centres and crispy golden edges.
- Drain them really well. Let the boiled potatoes sit for a minute or two so excess moisture can steam away. Watery potatoes make sticky dough.
- Mash until smooth. Break up any large lumps before adding the cornstarch. A smoother mixture is much easier to shape without cracking.
- Let the mixture cool slightly. Shape your fries while the potatoes are still a little warm but comfortable to handle. No need to make them perfectly identical!
- Keep the fries evenly sized. Aim for roughly the same thickness so they cook evenly and turn golden at about the same time.
- Don’t rush the first flip. Let the fries develop a crispy crust before turning. Chopsticks or small tongs work well without squashing them.
- Fry in batches and serve hot. Give each fry a little room in the pan, then sprinkle with salt and pepper immediately. They’re at their best straight from the skillet.
Crispy Mashed Potato Fries
Equipment
- Medium saucepan
- Colander
- Large mixing bowl
- Potato masher, ricer, or electric hand mixer
- Measuring cups and spoons
- Wooden spoon or spatula
- Large non-stick frying pan
- Tongs or chopsticks for turning the fries
- Plate lined with paper towel for draining
Ingredients
- 2 russet potatoes large
- ¼ cup (Scant) cornstarch
- ½ teaspoon salt
- ¼ teaspoon freshly ground black pepper
- 2 to 3 tablespoons cooking oil or enough to lightly coat the frying pan
- Extra salt and black pepper for serving
Instructions
Peel and cut the potatoes.
- Peel the russet potatoes and cut them into medium-sized chunks. Try to keep the pieces fairly even so they cook at roughly the same speed.
Boil until fork-tender.
- Place the potatoes in a saucepan and cover with cold water. Bring to a boil and cook for about 12 to 15 minutes, or until the potatoes are completely tender when pierced with a fork.
Drain the potatoes really well.
- Drain away all the cooking water and let the potatoes sit for a minute or two. This little rest lets some of the extra moisture steam away and helps create a better texture for shaping the fries.
Mash until smooth.
- Transfer the cooked potatoes to a bowl and mash until mostly smooth with no large chunks remaining. They don’t need to look perfectly whipped. Just make sure there aren’t big pieces that could make the fries break apart.
Add the cornstarch, salt and pepper.
- Sprinkle in just under ¼ cup cornstarch, along with the salt and freshly ground black pepper. Mix until the mashed potatoes come together into a soft, workable potato dough.
Shape the mashed potato fries.
- Take small portions of the potato mixture and gently roll them into long fry shapes on a clean work surface. Keep them fairly similar in thickness so they cook evenly. Mine weren’t perfectly identical, and that really doesn’t matter.
Heat the frying pan.
- Add enough cooking oil to lightly coat the bottom of a non-stick frying pan. Heat over medium heat until the oil is hot.
Pan-fry until golden and crispy.
- Carefully place the mashed potato fries into the hot pan in a single layer. Leave a little space between each one so they fry rather than steam.
Let the first side develop a crust.
- Cook for about 2 to 3 minutes before turning. Don’t rush this part. Giving the fries time to develop a golden crust makes them much easier to turn without breaking.
Turn and brown all sides.
- Gently rotate the fries using chopsticks or tongs and continue cooking until the outside is golden brown and crispy on all sides.
Season and serve immediately.
- Remove the fries from the pan and sprinkle with extra salt and freshly ground black pepper while they are still hot.
Notes
- Use russet potatoes for the best texture. Russets mash up light and fluffy, which makes them a great choice for crispy mashed potato fries with soft centres and golden edges.
- Drain the potatoes really well. Extra moisture can make the mashed potato mixture sticky and harder to shape. Let the boiled potatoes sit for a minute or two before mashing.
- Use just under ¼ cup cornstarch. This helps the mashed potato fries hold their shape and gives them that crisp exterior once they hit the hot pan.
- Mash until mostly smooth. A few tiny potato bits are fine, but large chunks can make the fries crack or break while shaping.
- Shape the fries while the mixture is still slightly warm. It is easier to work with, but not so hot that it sticks to your hands.
- Keep the fries close in size. They do not need to be perfect, but similar thickness helps them cook evenly and brown at the same rate.
- Do not flip too soon. Let the first side develop a golden crust before turning. This makes the crispy potato fries much easier to handle.
- Cook in a single layer. Give the fries a little room in the pan so they crisp instead of steam.
- Season right away. Sprinkle with salt and freshly ground black pepper while the fries are still hot so the seasoning sticks well.
- Serve immediately. These homemade mashed potato fries are best hot and fresh, when the outside is crisp and the inside is still soft and fluffy.
