Ingredients

3-4 Idaho potatoes
3 tbsp fresh grated Parmesan cheese
2 tsp white truffle oil (adjust to taste)
Coarse salt or sea salt
Parsley (optional garnish)

Parmesan Aioli:

1/2 cup mayonnaise
1/4 cup fresh grated Parmesan cheese
1 tsp fresh lemon juice
1 tsp Worcestershire sauce
1 tsp Dijon mustard
Pinch of salt
Pinch of black pepper

Instructions

Step 1: Make the Parmesan aioli by combining mayonnaise, Parmesan cheese, lemon juice, Worcestershire sauce, Dijon mustard, salt, and pepper in a small blender. Pulse a few seconds until well combined. Set aside.
Step 2: Wash and cut the potatoes into thin fries—aim for medium thickness for best results.
Step 3: Rinse the cut potatoes in cold water a couple of times, then soak them in cold water for about 30 minutes to remove excess starch. Drain, rinse again, and pat dry thoroughly with a towel.
Step 4: Choose your cooking method:
- Air-Fryer: Toss potatoes with a little olive oil and salt. Spread them in one or two layers in the air fryer basket. Air-fry at 400°F for about 20 minutes, shaking or tossing every 5 minutes for even cooking and crispiness.
- Deep Fryer (Double Fry): Heat oil to 350°F. Fry potatoes in batches for 4-5 minutes until soft but not browned. Drain on paper towels. Increase oil temperature to 400°F and fry again until golden and crisp. Drain on fresh paper towels and sprinkle with salt.
- Shortcut: Use frozen fries cooked according to package directions, then toss immediately with truffle oil and Parmesan.
Step 5: Place hot fries in a large bowl. Drizzle with white truffle oil and sprinkle grated Parmesan cheese. Toss quickly to coat evenly.
Step 6: Serve immediately with the Parmesan aioli and a sprinkle of chopped parsley if desired.

Tips & Variations

For extra crispy fries, dry your potatoes thoroughly before cooking and consider double frying.
Adjust the amount of truffle oil to your preference—a little goes a long way with its strong aroma.
Freshly grated Parmesan melts better and provides a more vibrant flavor than pre-grated cheese.
Try adding a pinch of garlic powder or smoked paprika to the fries for a flavor twist.
Use Yukon Gold potatoes if you prefer a creamier texture inside your fries.

Storage

Truffle fries are best enjoyed immediately for maximum crispiness. If you need to store leftovers, place fries in an airtight container in the refrigerator for up to 2 days. Reheat in a hot oven or air fryer to restore some crispness. The Parmesan aioli can be stored separately in the refrigerator for up to 3 days.

How to Serve

A white plate is filled with a large pile of golden brown French fries, some fries are darker and crispier while others are lighter and softer looking, sprinkled with grated cheese and small bits of green parsley. Two small white sauce dishes sit on opposite corners of the plate, filled with creamy, pale yellow dipping sauce. A sprig of fresh parsley adds a pop of green on top. The plate sits on a white marbled surface with a soft white cloth in the background. photo taken with an iphone --ar 4:5 --v 7

FAQs

Can I use frozen fries to make truffle fries?

Yes, frozen fries work well as a shortcut. Cook them according to package instructions, then toss with truffle oil and Parmesan cheese while hot.

How much truffle oil should I use?

Start with about 2 teaspoons for 3-4 potatoes and adjust to taste. Truffle oil has a strong flavor, so it’s best to add gradually to avoid overpowering the fries.
