French fry lovers unite, because these crispy parmesan truffle fries are a serious gourmet glow-up from traditional French fried fries. Generously drizzled with earthy truffle oil and tossed with freshly grated parmesan cheese, these fries are a flavor sensation you’ll want to pair with anything and everything.

By frying them twice, the fries get extra crispy on the outside while staying soft and fluffy on the inside. What’s not to love? Dip them in some buttermilk ranch, black garlic aioli, or blue cheese sauce for the ultimate flavor explosion.

  • Russet Potatoes. A high starch potato that is ideal for french fries.
  • Olive Oil.
  • Peanut or Vegetable Oil. For frying.

Is it Authentic Truffle Oil?

Determining the authenticity of truffle oil can be tricky, as the market is flooded with both real and synthetic versions. Here are some tips to help you get the real deal truffle flavor.

  • Ingredients: Real truffle oil lists actual truffle as a primary ingredient. Avoid oils with “truffle aroma” or “flavor” as these are typically synthetic.
  • Aroma and Taste: Genuine truffle oil has a complex, earthy scent and flavor. Artificial versions often smell overpowering and less nuanced.
  • Price: Authentic truffle oil, being made with costly truffles, is generally more expensive. A low price might indicate a synthetic product.
  • Brand and Packaging: Opt for reputable brands and look for oils in dark glass bottles, which protect from light degradation.
  • Shelf Life: Real truffle oil has a shorter shelf life (about 6-12 months). Longer shelf life could indicate the presence of artificial ingredients.

With all that said, if you don’t mind the flavor of the synthetic stuff, then save some money and use that for your fries. No judgement here.

For the Potatoes

  • 3 pounds Russet potatoes
  • 2 tablespoons olive oil
  • 2 to 3 quarts Peanut or vegetable oil for frying

For the Parmesan Truffle Seasoning (or see notes)

  • 3 to 4 tablespoons grated Parmesan cheese
  • 3 to 4 tablespoons truffle oil
  • 2 to 3 tablespoons chopped parsley
  • 2 teaspoons Kosher salt or 1-½ teaspoons truffle salt
  • 1 teaspoon garlic powder


Pre-Cook The Fries

  • Peel the potatoes and cut them into ½-inch thick fries and place them in a bowl of cold water for 30 minutes or overnight (this helps remove excess starch and makes the fries extra crisp). 
  • Drain the potatoes and add them to a large microwavable bowl. Toss them with 2 tablespoons of olive oil, then cover the bowl tightly with plastic wrap. 
  • Zap them in the microwave for 5 to 7 minutes or until tender but still slightly firm (thick-cut fries will need longer). Stop the microwave a few times and shake the fries around to prevent them from sticking to each other. 

Fry the Potatoes

  • Add some oil to a large deep fryer or a Dutch oven until it is at least 2 inches deep. Heat the oil over medium heat to 375°F. 
  • Add half of the potatoes to the hot oil and fry for 5 to 6 minutes or until golden brown. Gently stir the potatoes as they fry so they don’t stick to each other. 
  • Transfer the fries to paper towels to drain. Bring the fryer back up to 375°F before adding the next batch of fries. 
  • Return the first batch of fries to the fryer and fry them again to give them an extra crispy crunch. They will only need to fry for 1 to 3 minutes the second time. Repeat. 
  • Place the hot fries in a wide, large bowl and toss them with Parmesan cheese, truffle oil, parsley, salt, and garlic powder. 


  • Soaking the potatoes in cold water is optional but it will give the fries a crispier texture.
  • When you precook the potatoes, don’t let them get so tender that they fall apart. 
  • Another option to season the fries is to use Epicurean Specialty Truffle Parmesan & Black Garlic Seasoning. We found this seasoning in Costco and Walmart. It is less expensive than purchasing truffle oil and it has a great flavor. If you want to try it, use 3 to 5 tablespoons of the seasoning to toss with the fries instead of the truffle oil, salt, and Parmesan listed above.
