Ingredients

• 1.5 lbs (700g) russet potatoes, peeled and cubed
• 1/2 cup (60g) cornstarch
• 1/2 cup (50g) grated parmesan cheese
• 1 tsp garlic powder
• 1 tsp salt
• 1/2 tsp black pepper
• Neutral oil for frying (vegetable, canola, or peanut oil)

How to Make Crispy Potato Fingers

1. Place the cubed potatoes into a large pot of cold, salted water and bring to a boil over high heat.
2. Cook for 12 to 15 minutes until the potatoes are completely fork-tender, then drain well in a colander.
3. Return the hot potatoes to the pot and let them sit for 2 minutes to allow residual steam to dry them out.
4. Rice or mash the potatoes thoroughly until completely smooth with no remaining lumps.
5. Add the cornstarch, grated parmesan, garlic powder, salt, and black pepper to the warm potato mixture.
6. Mix with a spatula until a uniform, pliable dough forms that holds its shape.
7. Transfer the dough into a zip-top bag, press it flat to a half-inch thickness, and seal tight.
8. Chill the flattened dough in the freezer for 20 minutes until firm to the touch.
9. Slice the bag open and cut the slab into uniform 3-inch long fingers using a sharp knife.
10. Heat 1 inch of neutral oil in a deep skillet to 350°F (175°C) over medium heat.
11. Fry the potato fingers in small batches for 3 to 4 minutes, turning once, until deep golden brown.
12. Transfer with a slotted spoon to a wire rack lined with paper towels to drain excess oil.

If you enjoyed this potato version, you can adapt the same shaping method for high-protein egg fingers. Boil four large eggs, grate them finely on a microplane, and combine them with two mashed potatoes, two tablespoons of cornstarch, and your favorite fresh herbs. Shape the mixture into logs, roll them in panko breadcrumbs, and fry at 350°F for 3 minutes until crisp. They offer a rich, savory twist on the classic potato stick with extra protein in every bite.

Pro Tip

Moisture is the main reason potato dough falls apart in hot oil. Always let your boiled potatoes steam-dry in the hot pot before mashing, and never skip chilling the shaped dough in the freezer before frying. Cold dough hitting hot oil seals the exterior immediately, preventing the fingers from absorbing excess oil or disintegrating.

Serving & Storage

Serve these potato fingers piping hot alongside garlic aioli, ketchup, or hot sauce for dipping. If you have leftovers, let them cool completely and store them in an airtight container in the refrigerator for up to 3 days. Reheat them in an air fryer at 380°F for 4 minutes to restore their original crispiness without turning them soggy.

FAQs

Can I make these crispy potato fingers in an air fryer?

Yes, brush the chilled fingers lightly with oil on all sides and air fry at 390°F (200°C) for 12 to 15 minutes, flipping halfway through until golden.

Can I freeze potato fingers before frying?

\Yes, arrange the cut, un-fried fingers on a baking sheet lined with parchment paper, freeze until solid, and transfer to a freezer bag for up to 2 months. Fry directly from frozen, adding 1 to 2 extra minutes to the cooking time.

What potato variety works best for this recipe?

Russet or Yukon Gold potatoes work best because their high starch and low moisture content create a light interior and a crisp exterior. Avoid waxy red potatoes as they become gummy when mashed.
