These Parmesan Truffle Fries are super simple to make in only 30 minutes, and served with the most AMAZING truffle mayonnaise dipping sauce.

Guys. Truffle fries are awesome.

The truffle seasoning gives the fries this absolutely amazing earthy flavor, and the duck fat....oh that wonderfully rich duck fat...crisps the fries up, while the Parmesan cheese adds the perfect amount of umami flavor.

And the smell of baking truffle fries....good god is it incredible. I'm actually drooling a bit just sitting here writing about it. The truffle gives them the most incredible earthy flavor, like we get in our favorite truffle risotto.

What are Truffle Fries?

Truffle fries are thin cut fries (like shoestring fries) baked or fried until crispy, then drizzled with truffle oil or sprinkled with truffle seasoning. They are often also sprinkled with Parmesan cheese and other seasonings. 

This recipe bakes store bought shoestring fries with truffle seasoning and duck fat until crispy. Then truffle oil and Parmesan cheese are sprinkled on top.

Easy peasy.

Ingredients

The best part about these fries is that you can use frozen shoestring fries. Perhaps making your own fresh cut potatoes is better, but I'm all about the lazy way. I'm perfectly content with the store bought frozen ones. 

OR...you can do this with parsnips and make baked parsnip fries!

Duck fat. My opinion is you should always have some duck fat in your pantry. It's so good on so many things. I included a link in the recipe card to buy it if you don't already have it. 

What Are Truffles?

Truffles are fungus, similar to mushrooms (some consider them mushrooms but there is debate about that) that grow near tree roots. There are white and black versions. I use black in this recipe.

The reason they are so expensive is due to the work and time it takes to harvest them. 

Now, real truffles are super expensive, so I found this amazing truffle "zest" that I absolutely love. Is it exactly the same of fresh grated truffles? No. But it is reasonably priced, has amazing flavor, and can be bought right on Amazon. BUY IT HERE (Amazon affiliate link). I've also included a link to buy in the recipe card.

Step By Step Instructions

Preheat oven to 425 degrees (or follow instruction on the package).

Remove the fries from the bag and spread them on a baking sheet. Drizzle them with melted duck fat, salt and truffle seasoning. Toss to coat the fries.

Pro Tip: For an easier cleanup, line the baking sheet with parchment paper.

Bake for 20-30 minutes, stirring halfway through. Once golden brown and crisped on the edges, remove them from the oven, sprinkle with Parmesan cheese, drizzle with truffle oil and serve with your truffle mayonnaise.

How to Make Truffle Mayonnaise

Mix the ingredients in a bowl. Done. LOL. Easy right? Check out these other ideas for using truffle mayonnaise:

• It is awesome on sandwiches - try it on this Prime Rib Sandwich from Self Proclaimed Foodie;
• Dip these Crispy Roasted Potatoes in it;
• Parmesan Roasted Asparagus can be drizzled with the mayonnaise...it goooood. It would be great on any roasted vegetable;
• Dip these Corn Fritters in it.

Expert Tips

1. Make sure the fries are spread out evenly on the baking sheet so they cook evenly;
2. Cover the baking sheet with parchment paper for an easy cleanup;
3. Stir the fries halfway through to get even browning;
4. Sprinkle the Parmesan cheese and the truffle oil on AFTER the fries have finished baking. Neither are meant to be baked with the fries;
5. The truffle oil at the end is optional - you can leave it out if desired, but your fries won't have as much truffle flavor;
6. Sprinkle additional truffle zest over the fries after baking for even more truffle flavor.
