Parmesan-Dusted Truffle Fries
These russet fries finish golden, with a light coating of Parmesan and parsley. A 30-minute cold-water soak and a thorough dry help them crisp; give them space on the baking trays, or cook small batches in the air fryer. Toss the fries with just a little truffle oil and salt after cooking, while they’re hot. Serve right away, when the edges are crisp and the cheese still clings.

Ingredients
Instructions
- 1
Cut and soak the potatoes
Scrub the potatoes and peel if you prefer. Cut into even sticks about ¼ inch thick. Put them in a large bowl, cover with cold water, and soak for 30 minutes. Even thickness helps the fries cook at the same rate.
- 2
Dry thoroughly
Drain the potatoes, spread them on a clean kitchen towel, and pat dry on all sides. A salad spinner can help remove water first, but finish with the towel. Surface moisture makes crisping harder.
- 3
Choose the oven or air fryer
For the oven, heat to 425°F and set out large rimmed metal baking trays; use 2 trays if needed so the fries fit without crowding. For the air fryer, preheat to 380°F if your appliance calls for preheating. Choose either method below, then finish with the truffle oil, salt, cheese, and parsley.

Oven method
Toss the dried potatoes with the full 3 tablespoons neutral oil until lightly coated. Spread in a single layer on the baking trays with space between pieces. An oven-safe wire rack set in a tray is optional; a metal tray also works. Bake for 20 minutes, then turn the fries and rotate the trays, swapping racks if using both. Bake for 15 to 20 minutes more, until golden and tender inside. Thicker pieces may need longer.
- 5
Air-fryer method
Instead of baking, toss the dried potatoes with 1½ tablespoons neutral oil. Cook at 380°F in small batches, with space for air to circulate. Start with 8 minutes, shake the basket, then cook for another 6 to 12 minutes, until golden and tender inside. Check often near the end; size and appliance affect timing. The full amount will need several batches in most air fryers. Keep cooked batches on a tray in a low oven while you finish the rest, and season the whole batch together.

Add truffle oil and salt
Transfer the hot cooked fries to a large bowl. Drizzle over the truffle oil and toss gently to distribute. Add the truffle salt or kosher salt gradually, tasting as you go; brands vary, and the Parmesan adds salt too.
- 7
Dust with Parmesan and serve
Scatter over the finely grated Parmesan and parsley, then toss briefly so they cling to the warm fries. Divide into 4 portions and serve immediately. Avoid covering the fries tightly, which traps steam and softens the coating.

Crisp edges start with dry potatoes
Soaking rinses away some surface starch. Dry the fries thoroughly afterward and keep the layer uncrowded so moisture can escape. A soak alone cannot prevent soft fries if they are crowded or undercooked.
A baking rack is optional. Fries can brown well directly on a metal tray; turn them halfway through and give them room. Thicker sticks need more time than thin ones.
Add the truffle oil after cooking
Use truffle oil as a finishing seasoning. Add it to the hot cooked fries so you can distribute a small amount evenly and keep its aroma more noticeable. Truffle oils vary in strength, so start with less if yours is especially strong.
Finely grated Parmesan adheres more easily than thick shreds. Fill the measuring cup loosely rather than pressing the cheese down. Toss it in just before serving.
Timing and nutrition
The displayed time includes the 30-minute soak and the oven method. Air-fryer time is per batch; cooking the full 2 pounds can take longer in a small basket.
Nutrition is estimated for 1 of 4 portions using the oven method, its full 3 tablespoons neutral oil, truffle oil, Parmesan, and the first-listed fresh parsley. The air-fryer method uses less neutral oil and changes the estimate.
Reheating
Reheat in a 400°F oven for about 8 to 10 minutes or an air fryer at 375°F for about 3 to 4 minutes, checking until hot and crisp. The Parmesan can brown quickly. Leftovers will be softer than freshly cooked fries.
Frequently Asked Questions
Why are my oven fries soggy?
Common causes are wet potatoes, crowded trays, or removing the fries before they have browned. Pat them dry after soaking, spread in a single layer with space, and turn during baking. A wire rack is optional; direct contact with a metal tray can also give good browning.
Can I make these in an air fryer?
Yes. Use 1½ tablespoons neutral oil, cook at 380°F in small batches, and shake after 8 minutes. Allow another 6 to 12 minutes, checking for golden edges and a tender center. Total time for the whole recipe depends on how many batches fit in your air fryer.
When do I add the truffle oil?
Toss it with the fries after cooking, while they are still hot. It is easier to control the amount and keep the aroma noticeable when it is used as a finishing seasoning.
What if I do not have truffle oil?
Use a small drizzle of olive oil and truffle salt instead, tasting before adding more salt. For Parmesan fries without truffle flavor, use regular salt and keep the Parmesan and parsley. Substitutions change the nutrition estimate.
Can I use store-bought frozen fries?
Yes. Cook according to the package directions until crisp, then toss with the truffle oil, salt, Parmesan, and parsley. Frozen fries often already contain oil and salt, so taste before seasoning and do not automatically add the raw-potato oil quantity. Their nutrition will differ.
How do I reheat leftover fries?
Use a 400°F oven for about 8 to 10 minutes or an air fryer at 375°F for about 3 to 4 minutes. Check often so the cheese does not scorch. A microwave warms the fries but does not restore a crisp surface.
