What Are Truffle Fries?
Truffle fries are typically french fries tossed with truffle oil, parmesan cheese, herbs, and sometimes garlic. They became especially popular at gastropubs and steakhouses because the earthy truffle flavor pairs incredibly well with crispy potatoes.
Most truffle fries are made using truffle oil rather than fresh truffles, which keeps them much more affordable and accessible for home cooking. The key is using just enough truffle oil to add flavor without overpowering the fries.
This version leans into the garlic parmesan side of things for a more balanced, restaurant-style flavor that works perfectly with crispy homemade fries.

Best Potatoes for Homemade Truffle Fries
Russet potatoes are the best choice for homemade Air Fryer Truffle Fries because their high starch content creates crispier fries with soft, fluffy centers.
Waxy potatoes like red potatoes or Yukon gold potatoes tend to hold more moisture, which makes it harder to get that classic crispy restaurant-style texture.
If you want fries that feel closer to steakhouse truffle fries, russets are definitely the way to go.
How To Make Air Fryer Truffle Fries
Cut the Potatoes
Slice the potatoes into evenly sized fries so they cook at the same rate. Thin fries crisp faster while thicker fries stay fluffier inside, so you can slightly adjust based on your preference.
Soak the Potatoes
Soak the cut potatoes in cold water for at least 20–30 minutes. This removes excess starch and helps the fries crisp up better in the air fryer instead of steaming.
Dry and Season
Dry the potatoes extremely well before seasoning. Excess moisture prevents browning, so this step makes a huge difference in texture.
Toss the potatoes with olive oil, salt, and pepper until evenly coated.
Air Fry Until Crispy
Arrange the fries in a mostly even layer in the air fryer basket. Avoid overcrowding so the hot air can circulate properly around the fries.
Air fry until deeply golden and crispy, shaking the basket halfway through cooking. Depending on your air fryer, you may need to cook in batches for the crispiest results.
Toss with Garlic Butter and Parmesan
While the fries cook, stir together melted butter and grated garlic in a large bowl.
As soon as the fries come out of the air fryer, toss them in the garlic butter while they’re still hot. Then add the finely grated parmesan cheese and fresh herbs so everything clings to the fries evenly.
Finish with Truffle Oil
Drizzle the truffle oil over the fries at the very end after cooking. A little goes a long way, so start with a smaller amount and add more if needed. Adding truffle oil after cooking keeps the flavor fresh and prevents it from becoming overpowering. Sprinkle with flaky salt and optional French seasoning before serving.
Tips for Crispy Truffle Fries in the Air Fryer
- Dry the potatoes thoroughly after soaking
- Avoid overcrowding the air fryer basket
- Cook in batches if necessary
- Shake the basket halfway through cooking
- Use finely grated parmesan for better coverage
- Add truffle oil after cooking, not before
- Serve immediately for the crispiest texture
Frozen Fries Shortcut Version
If you want a faster version, you can absolutely make these Air Fryer Truffle Fries using frozen fries.
Cook a 24 oz bag of frozen fries according to package directions until extra crispy, then toss them with the garlic butter, parmesan cheese, herbs, and truffle oil exactly as written in the recipe.
It’s an easy shortcut for busy nights while still giving you that garlic parmesan truffle fry flavor.
What to Serve with Truffle Fries

Frequently Asked Questions
What kind of truffle oil is best for truffle fries?
Most grocery stores carry black truffle oil or white truffle oil. Black truffle oil tends to have a deeper, earthier flavor while white truffle oil is usually a little sharper and more aromatic.
Can I make truffle fries with frozen fries?
Yes. Frozen fries work great as a shortcut version. Just cook them until crispy first, then toss with the garlic parmesan truffle mixture.
Why soak potatoes before air frying?
Soaking removes excess starch from the potatoes, which helps the fries crisp better and prevents them from sticking together.
How do you keep truffle fries crispy?
Serve them immediately after tossing with the toppings and avoid overcrowding the air fryer basket during cooking.
What cheese goes best with truffle fries?
Finely grated parmesan cheese works best because it melts slightly onto the hot fries and evenly coats them.
Are truffle fries made with real truffles?
Most truffle fries are made with truffle oil rather than fresh truffles. Truffle oil gives the fries their signature flavor while being much more affordable and practical for home cooking.
Storage and Reheating
These fries are best fresh, but leftovers can be stored in an airtight container in the fridge for up to 3 days.
To reheat, place the fries back in the air fryer at 375°F for 3–5 minutes until crispy again. Avoid microwaving if possible since it softens the fries.

- Immediately add the hot fries to the bowl with the garlic butter and toss well to coat.
- Sprinkle in the finely grated parmesan cheese and parsley or chives, tossing again so the cheese evenly coats the fries.
