Parmesan Truffle Fries with Truffle Mayonnaise

This post may contain affiliate links. Please read my disclosure.

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. You can even make them using this air fryer frozen french fries recipe!

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 and truffle mashed potatoes.

These fries go perfect with this sous vide venison too!

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.

Ingredients

The full list of ingredients and amounts is included in the recipe card at the bottom of the post.

The best part about these fries is that you can use frozen shoestring fries.

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.

Fresh grated Parmesan cheese is a must to get the best flavor - that grated kind in the green container that shall remain nameless is not my thing.

And the optional truffle oil I love to use too - you don't have to, the fries have a great earthy flavor without them - but it adds an extra layer of earthiness that I love. But be careful, many truffle oils are not made with real truffles so I recommend using Truff or Terosso.

What Are Truffles?

Truffles are fungus, similar to mushrooms (some consider them mushrooms but they are not) 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. Truffles grow underground so they are not easy to find!

Now, real whole truffles are super expensive, so I found this amazing truffle "zest" that I absolutely love (it's made with real truffles, don't worry). 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.

If you're a truffle fan, you MUST try this black truffle pasta!

Step By Step Instructions

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

Remove the fries from the bag and spread them evenly in a single layer 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 or aluminum foil.

Bake for 20-30 minutes, flipping 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 sous vide roast beef sandwich;
• 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 oven fried squash coins in it;
• Spread it on this bison burger or even these sous vide hamburgers.

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.
