French fries: Frozen fries are convenient and crisp up reliably. You can also use homemade fries made from Russet potatoes.
Parmesan: Freshly grated Parmesan adds a nutty, salty finish. Pecorino Romano can be substituted.
Seasonings: Kosher salt and freshly ground black pepper to taste.
Parsley: Finely chopped fresh parsley for garnish and brightness.
The full ingredient quantities are in the recipe card below.
Tips and Substitutions
- Use truffle salt: Replace kosher salt with truffle salt to boost the umami.
- Try toppings: Add chopped herbs like parsley, rosemary, or thyme. Toss with a spoonful of garlic confit or a little freshly grated garlic for extra depth.
- For Parmesan: Pecorino Romano is an easy swap for Parmesan.
- Reheating: Re-crisp leftover fries in an air fryer or a preheated oven for a few minutes to restore texture.
How to Make Parmesan Truffle Fries
Step 1: Preheat the oven or air fryer to 400°F (about 200°C). If baking, line a sheet pan with parchment paper and arrange frozen fries in a single layer.
Step 2: Cook until golden and crisp — roughly 25–30 minutes in the oven or 15–20 minutes in an air fryer, flipping once halfway through.
Step 3: Place the hot fries in a large bowl. Drizzle with truffle oil, season with salt and pepper, and sprinkle with grated Parmesan. Toss gently with tongs until evenly coated.
Step 4: Transfer to a serving platter and finish with extra Parmesan and chopped parsley.
