Want to replicate your gourmet bar food favorite at home? These Parmesan Truffle Fries are crispy, crunchy, truffle perfection, and can be made in the oven or the air fryer!
When it comes to snacks, appetizers, and sides, nothing beats homemade hand-cut fries! And the addition of truffle, parmesan, and fresh parsley makes a good thing even better!
Learn how to make crispy, hand-cut parmesan truffle fries with this recipe! The key to getting crispy baked fries is to remove the excess starch before cooking by soaking the thin, cut potato strips in water! Instructions below.
Parmesan Truffle Fries Ingredient Highlights
The best potatoes for French fries are russet or Idaho because of their lower moisture and ability to get nice and crispy.
I highly recommend using olive oil over any other oil. Canola, grapeseed, and vegetable oil will leave your baked fries too greasy, especially when finishing with truffle oil.
I like to freshly grate it from a block, but you can buy pre-shredded or pre-grated. Shaved parmesan tends to be a little bit too big.

How I Peel and Cut My Fries
I use a vegetable peeler to peel the skins off my potato. You don’t have to be too meticulous- some small bits of skin left behind is totally fine.
To hand cut fries, slice your potato longways so you’re left with slices roughly ½-inch wide. Then, lay those slices flat and cut them into thin fries. Use your discretion, slicing thicker ones in half, so that each fry is as similar as size as you can get them without stressing.
Keeping them roughly uniform will help them cook more evenly.
I Always Soak My Homemade Fries
The key to getting crispy baked fries is removing excess starch. The best way to do so is to soak them in water.
Once you’re happy with the shape and thickness of your fries, add them to a large mixing bowl and add enough water to cover them completely.
Allow them to sit in the water for 30 minutes to 1 hour before rinsing. You should be able to see the white starch left in the bowl of water.
After soaking, try to remove as much water as you can after rinsing the potatoes. I usually let them sit in a strainer for a couple of minutes before drying them with a clean kitchen towel.
Then, I spread them out on a baking sheet and use another clean kitchen towel to remove any excess water I missed.
How I Prep My Truffle and Parmesan Fries for the Oven
Once you are confident that your fries are dry, spread them out evenly across a baking sheet and add the olive oil.
Use your hands to toss, ensuring that each fry is coated in the oil. Then, spread them back out on your baking sheet. It’s important to not stack them on top of one another. Use two trays if need be.
Whether you are oven-baking or air frying your truffle fries with Parmesan, make sure you toss them halfway through cooking to get them crispy on all sides.
How I Get the Most Distinct Truffle Taste
After removing your fries from the oven, use a paper towel to blot the fries, removing excess oil. This is important as we are adding truffle oil on top. We don’t want them to be too crispy!
After blotting, sprinkle salt evenly over your French fries.
Pro tip: It’s important to understand that truffle oil is a finishing oil, not a frying oil.
Cooking the fries in the truffle oil will burn off that truffle flavor, so we want to finish the fries with the truffle oil instead!
Once you’ve peeled, soaked, cut, baked (or air-fried!), and salted your fries, it’s finally time for the aromatic truffle oil.
Simply drizzle it evenly on top and toss your fries to make sure each one has a little bit of truffle.
Hit them With Parmesan & Parsley
I love to use freshly grated Parmesan for its more robust flavor. If you are a cheese lover like me, I highly recommend this handheld rotary cheese grater as pictured below.
Otherwise, you can use any shredded or grated parmesan. Shaved usually comes in too-large chunks for the thinness of your fries.
Adding fresh parsley not only makes these fries more visually appealing but adds some freshness to an otherwise heavy treat.
Chop your parsley finely and sprinkle it on top of your crispy fries.
How I Store and Reheat Fries with Truffle and Parmesan
These Parmesan Truffle Fries will last in an airtight container in the refrigerator for 3-5 days or in the freezer for 6 months. Reheat in your pre-heated oven at 425°F for 15-20 minutes until crispy. If frozen, they will need closer to 30 minutes.
In the air fryer, heat them until crispy (3-5 minutes) at 350°F.
Note that reheating the fries means you will lose that truffle taste. You may want to add more truffle oil to finish once they are reheated.
