Ultra-Crispy Parmesan Truffle Shoestring Fries Tips, FAQ & printable recipe

Tips for success

To keep the fries crispy for the full hour, place them on a wire cooling rack after frying rather than on a plate or paper towels.

This allows air to circulate around all sides of the fries, preventing steam from building up and softening the bottoms. Using a wire rack ensures that the fries stay dry and maintain their signature glass-like crunch from the first bite to the last.

The temperature of the oil is paramount. If you do not have a digital thermometer, test the oil with a single piece of potato; it should bubble intensely and rise to the surface immediately. If the fries darken too quickly without becoming crispy, the oil is too hot; if they take too long to turn golden, the oil is not hot enough and they will absorb too much fat.

Variations

• Garlic Herb Fries: Replace the truffle oil with high-quality extra virgin olive oil and toss the hot fries with two tablespoons of finely minced fresh garlic and an extra tablespoon of fresh parsley.
• Spicy Cajun Fries: Omit the truffle oil and cheese. Instead, toss the hot fries with a tablespoon of Cajun spice blend and a squeeze of fresh lime juice for a zesty, heat-forward variation.

Storage and make-ahead

Fridge

Store par-boiled potatoes in the refrigerator for up to 24 hours. Do not store finished fries in the fridge as they will lose their crispness.

Reheat

Reheat in a 400°F (200°C) oven for 5 minutes on a wire rack until crisp, though fresh is always preferred.

Store any leftovers in an airtight container at room temperature for up to 24 hours, though they are best enjoyed fresh.

Because these fries rely on a specific moisture-free texture to achieve their crunch, they will naturally soften over time as they absorb ambient humidity. Avoid sealing them while they are still warm, as this will trap steam and cause them to become limp almost immediately.

The potatoes can be sliced and par-boiled up to 24 hours in advance. After the 2-minute vinegar boil, drain them thoroughly and store them in the refrigerator in a sealed container lined with paper towels.

When ready to serve, bring them to room temperature for 20 minutes, pat them dry again, and proceed with the flash-frying step. This method allows for quick service without sacrificing the quality of the final result.

Serving ideas

Serve these fries immediately in a large, wide bowl to allow guests easy access. Pairing them with a simple garlic aioli or a light dipping sauce can complement the truffle and Pecorino flavors without overpowering them. The presentation should be rustic yet elevated, making them a perfect centerpiece for a casual gathering or a sophisticated dinner party appetizer.

Given the intensity of the truffle oil and the sharp saltiness of the Pecorino, these fries pair exceptionally well with crisp, acidic white wines or a light, refreshing lager.

The brightness of the beverage helps to cut through the richness of the fried potatoes and the aromatics of the oil, balancing the palate with every bite and ensuring each portion remains enjoyable until the very end.

Ultra-Crispy Parmesan Truffle Shoestring Fries

Prep 20 minCook 5 minTotal 25 minServes 4

Ingredients

• 600 g Russet potatoes
• 2 tbsp white vinegar
• 4 cups peanut oil
• 1.5 tbsp white truffle oil
• 60 g Pecorino Romano cheese, finely grated
• 1 tbsp fresh parsley, minced

Instructions

1. Using a mandoline, slice the potatoes into 3mm shoestrings. Rinse the potato matchsticks thoroughly in cold water until the water runs completely clear. Place the potatoes in a pot of boiling water mixed with the vinegar and cook for 2 minutes. Remove and dry them completely on clean kitchen towels to ensure a crispy final result.
2. Heat the peanut oil in a deep pot to 380°F (193°C). Working in two small batches to maintain oil temperature, carefully lower the prepared potato matchsticks into the hot oil. Fry for 2.5 minutes until the moisture has evaporated completely and the fries turn rigid and golden brown. Remove carefully with a slotted spoon and drain briefly.
3. While the fries are still hot, transfer them to a large mixing bowl. Drizzle immediately with the white truffle oil, add the finely grated Pecorino Romano, and sprinkle with the fresh minced parsley. Toss the fries vigorously in the bowl to ensure every matchstick is coated evenly with the oil and cheese. Serve immediately.
