Transform leftover mashed potatoes into irresistible crispy fries. These golden sticks feature a perfectly seasoned fluffy interior with a satisfying crunch on the outside. Shape using a piping bag with a star tip for restaurant-style presentation, or form by hand for rustic appeal.

Bake at high heat for lighter results or deep fry for ultimate crispiness. The addition of egg helps the potato mixture hold its shape while cooking, while garlic powder, onion powder, and smoked paprika add layers of savory flavor.

Serve these crowd-pleasing fries with your favorite dipping sauces like ketchup, garlic aioli, or spicy mayo. They make an excellent side dish for burgers, sandwiches, or as a satisfying snack on their own.

Last winter, I found myself staring at a container of leftover mashed potatoes after a dinner party, unwilling to let them go to waste but too tired to make shepherd's pie. On a whim, I shaped them into fry-like sticks and popped them in the oven. What came out was unexpectedly glorious—crispy golden exteriors giving way to clouds of fluffy, seasoned potato inside. My roommate wandered into the kitchen, stole one off the cooling rack, and immediately asked when I'd be making them again.

I made these for a game night with friends last month, and they disappeared faster than the actual main dish. Everyone kept hovering around the baking sheet, sneaking just one more until there were literally none left. Now they request them every time, and I've learned to double the batch.

Ingredients

  • 1 kg russet potatoes: These starchy potatoes create the fluffiest interior and crispest exterior
  • 60 ml whole milk: Adds creaminess without making the mixture too wet to shape
  • 30 g unsalted butter: Use room temperature so it incorporates smoothly into the mash
  • 1 large egg: This is the secret binder that keeps the fries from falling apart during cooking
  • 1 tsp garlic powder: Provides savory depth without the risk of raw garlic burning
  • 1 tsp onion powder: Balances the garlic and adds classic comfort food flavor
  • 1/2 tsp smoked paprika: Gives a subtle smoky note and beautiful golden color
  • Salt and black pepper: Season generously since potatoes need salt to shine
  • 500 ml vegetable oil: Only if frying, and save it for reuse afterward
  • Fresh parsley or Parmesan: Totally optional but makes them look restaurant worthy

Instructions

Boil the potatoes until tender:
Bring a large pot of salted water to boil, add the potato chunks, and cook for 15 to 18 minutes until a fork slides through easily
Create a smooth, seasoned mash:
Drain thoroughly, return to the pot, and mash until completely smooth before stirring in butter, milk, and all seasonings
Let the mash cool slightly:
Wait about 10 minutes so the egg doesn't scramble when you mix it in, then incorporate it thoroughly
Shape your fries:
Transfer to a piping bag with a large star tip for restaurant style ridges or simply form sticks by hand
Cook them crispy:
Bake at 220°C for 20 to 25 minutes, turning halfway, or fry in oil at 180°C for 2 to 3 minutes until golden

These became my go to when I need something impressive but effortless, proof that the best kitchen experiments often come from refusing to waste food. My niece now calls them special fries and gets genuinely excited when she sees me piping them onto the sheet.

Making Them Ahead

I've learned that you can pipe or shape these fries up to a day ahead and store them on a parchment lined baking sheet in the refrigerator. They actually crisp up even better when they go into the oven cold, since the exterior dries out slightly overnight. Just add an extra minute or two to the cooking time if baking from chilled.

Baking Versus Frying

Both methods yield fantastic results, but they're different experiences. Baking creates a lighter, slightly drier crisp with less mess, perfect for a weeknight when you don't want to deal with hot oil. Frying gives you that deep golden color and irresistible crunch that makes them feel like they came from a restaurant. Honestly, I usually bake them unless I'm already frying something else.

Serving Suggestions

These fries are remarkably versatile on their own, but the right accompaniments can elevate them further. I love serving them with a garlic aioli for dipping or sprinkling them with grated cheddar while they're still hot so it melts into all the ridges.

  • Try dusting them with everything bagel seasoning right after baking
  • A squeeze of fresh lemon juice brightens all that richness
  • Pair with a simple green salad to balance the comfort food factor

Recipe FAQs

Yes, leftover mashed potatoes work perfectly. Ensure they're cold and not too loose. Add a tablespoon of flour or cornstarch if the mixture seems too wet to hold its shape.

For maximum crunch, dust the shaped fries lightly with cornstarch before cooking. When baking, flip halfway through and increase heat slightly for the last 2-3 minutes. When frying, avoid overcrowding the pot.

Shape the fries and freeze them uncooked on a baking sheet. Once frozen, transfer to a bag. Cook from frozen, adding a few extra minutes to baking time or lowering oil temperature slightly when frying.

A piping bag with a star tip creates classic ridged fry shapes, but it's optional. You can shape by hand into sticks, use a cookie cutter, or even scoop small mounds for tot-style bites.

These fries pair beautifully with garlic aioli, spicy mayo, truffle mayo, chipotle ketchup, or classic ranch dressing. The smoky paprika notes also complement barbecue sauce wonderfully.

Absolutely. Air fry at 200°C (400°F) for 12-15 minutes, shaking halfway. Lightly spray with oil for better browning. They may be slightly less crispy than deep-fried but still delicious.
