Drizzle with truffle oil.
Sprinkle in the grated Parmesan and chopped parsley.
Gently toss until all fries are evenly coated.

Make the aioli:

In a small bowl, mix together the mayonnaise, truffle oil, lemon juice, garlic powder, and a few grinds of black pepper.

Servings and timing

This recipe serves 2 to 4 people. Preparation takes about 10 minutes, with an additional 15 minutes for frying and assembling. Total time is approximately 25 minutes.

Variations

Baked version: Bake the fries at 425°F (220°C) for 25–30 minutes for a healthier option.
Sweet potato twist: Use sweet potatoes for a sweeter contrast with the truffle and Parmesan.
Herb boost: Add chopped rosemary or thyme for extra aromatic notes.
Cheese change: Try using Pecorino Romano or Asiago instead of Parmesan.
Spicy aioli: Add a dash of sriracha or cayenne to the aioli for heat.

storage/reheating

For best results, enjoy the fries immediately. If storing, place them in an airtight container in the refrigerator for up to 2 days. To reheat, bake them in a preheated oven at 375°F (190°C) for 10–12 minutes until crispy again. Avoid microwaving, as it will make the fries soggy.

FAQs

Can I use frozen fries instead of fresh potatoes?

Yes, frozen shoestring fries work perfectly and save time. Simply fry or bake according to the package directions.

What kind of truffle oil should I use?

Use a high-quality white or black truffle oil. White truffle oil offers a more subtle, garlicky note, while black is more earthy and intense.

Can I air-fry the fries?

Yes, air-fry at 400°F (200°C) for 15–20 minutes, shaking the basket halfway through for even cooking.

What is the best type of potato to use?

Russet potatoes are best due to their high starch content, which yields crispier fries.

How do I keep the fries crispy?

Fry in small batches to avoid overcrowding, and drain on paper towels to remove excess oil. Serve immediately after tossing.

Is there a vegan version of the aioli?

Yes, you can use vegan mayonnaise and omit the Parmesan or use a plant-based alternative.

Can I make the aioli in advance?

Yes, it can be made up to 2 days in advance and stored covered in the refrigerator.

Are truffle fries gluten-free?

Yes, provided the oil and other seasonings are free from cross-contamination, this recipe is gluten-free.

Can I add garlic to the fries?

Absolutely. Fresh minced garlic or garlic powder can be added for extra flavor, but be cautious not to overpower the truffle oil.

What else can I serve with truffle Parmesan fries?

These fries pair well with gourmet burgers, grilled steak, or even as a standalone appetizer with sparkling wine.
