Kellie’s Note
Fry If You Want To
I’m a French fry freak….and I’m not sorry about it. A crispy French fry is my weakness and my total diet downfall but life is too short to shun our favorite foods like my favorite Sweet Potato Fries.
The only thing better than a humble French fry are Parmesan Truffle Fries and with just one bite, you’ll know why. I did try to health things up a bit by baking my French fries but, let’s just be real here, they are not totally healthy. But they’re totally worth it.
Almost every restaurant in the United States has some type of truffle fries on the menu but my favorite are those that are tossed with a healthy sprinkling of parmesan cheese.
Parmesan Truffle Fries are crispy, crunchy potato French fries that are tossed with truffle oil or truffle butter before being served with grated parmesan cheese.
Why You’ll Love These Truffle Fries
- Crispy without deep frying: The fries bake at high heat until golden outside and fluffy inside.
- Restaurant-style flavor: Truffle butter and freshly grated Parmesan turn simple potatoes into an impressive side dish.
- Easy to prepare ahead: Cut and soak the potatoes up to 24 hours before baking.
- Made with simple ingredients: You only need potatoes, oil, truffle butter, Parmesan, salt, and parsley.
- Easy to pair: Serve them with burgers, steak, seafood, sandwiches, or your favorite dipping sauce.
What Are Truffle Fries?
Truffle fries are French fries finished with truffle oil, truffle butter, truffle salt, or, less commonly, fresh truffles. They’re often topped with grated Parmesan and fresh herbs.
This version is baked rather than deep-fried and finished with black truffle butter, Parmesan cheese, and parsley. The result is a crispy, savory side dish that’s easy enough to make at home.
Ingredients for Parmesan Truffle Fries
- Russet potatoes: Their starchy texture creates crisp edges and fluffy centers. Cut them evenly so they finish baking at the same time.
- Olive oil: Helps the fries brown and crisp in the oven.
- Black truffle butter: Adds rich truffle flavor and helps the Parmesan stick to the hot fries.
- Kosher salt: Seasons the potatoes. Adjust the amount to taste.
- Parmesan cheese: Grate it fresh from a wedge for the best flavor and texture.
- Fresh parsley: Adds color and a fresh finish that balances the butter and cheese.
Ingredient Substitutions
- Yukon Gold potatoes can be used, although the centers will be creamier and less fluffy.
- Pecorino Romano can replace the Parmesan for a sharper, saltier flavor.
- Truffle oil can replace truffle butter, but it should be added sparingly after baking.
- Chives may be used instead of parsley.
How to Make Truffle Fries
- Cut the potatoes: Slice the potatoes into evenly sized fries approximately ¼ inch thick.
- Soak: Place the fries in a large bowl of cold water and soak for 1 hour.
- Dry thoroughly: Drain the potatoes and pat them completely dry with clean kitchen towels or paper towels.
- Add the oil: Toss the dry potatoes with olive oil until evenly coated.
- Arrange on the pan: Spread the fries in a single layer on a parchment-lined baking sheet. Leave space between them and do not overlap.
- Bake: Bake at 425°F for 15 minutes. Flip and continue baking for another 15–20 minutes, or until golden, crisp at the edges, and tender inside.
- Add the truffle butter: Melt the truffle butter while the fries finish baking. Transfer the hot fries to a large bowl and toss with the butter.
- Finish and serve: Add the Parmesan, parsley, and kosher salt. Toss gently and serve immediately.
If you’re thinking of something more garlic-y, you can toss your fries with this Garlic Butter Sauce before sprinkling with cheese….you won’t regret it. I promise you that!
Tips for Crispy Baked Truffle Fries
- Cut the fries to a consistent thickness so they cook evenly.
- Soak the potatoes to remove excess surface starch.
- Pat the potatoes completely dry after soaking. Moisture creates steam and prevents crisping.
- Arrange the fries in one layer with room between each piece.
- Use two baking sheets rather than overcrowding one pan.
- Flip the fries halfway through baking so both sides brown.
- Add the truffle butter and Parmesan only after the fries are fully cooked.
- Serve the fries immediately because they gradually soften after being dressed.
What is Truffle Butter?
Truffle butter is butter blended with truffles, truffle flavoring, mushrooms, or a combination of those ingredients. Depending on the product, it may contain black truffles, white truffles, or other natural and artificial flavorings.
I prefer truffle butter for these fries because it gives them a rich, rounded flavor and helps the Parmesan and parsley coat the potatoes evenly. Look for it in the specialty dairy section of a well-stocked grocery store.
Truffle Butter vs. Truffle Oil
- Truffle butter gives the fries richness as well as truffle flavor. Truffle oil has a more concentrated aroma and can quickly overpower the other ingredients.
- When substituting truffle oil, add it after the fries come out of the oven. Start with a small drizzle, toss, and taste before adding more.
- White truffle oil is often milder, while black truffle oil usually has a stronger flavor. The intensity varies by brand, so use a light hand.
Parmesan Truffle Fries Variations
- Garlic truffle fries: Stir a small amount of finely grated garlic into the warm truffle butter.
- Lemon-Parmesan fries: Add fresh lemon zest with the Parmesan and parsley.
- Spicy truffle fries: Add crushed red pepper flakes, cayenne, or freshly ground black pepper.
- Extra-cheesy fries: Add more freshly grated Parmesan immediately before serving.
- Truffle-oil fries: Replace the truffle butter with a light drizzle of white or black truffle oil.
- Herb truffle fries: Replace or combine the parsley with fresh chives or thyme.
Optional Air-Fryer Variation
For air-fryer truffle fries, cook the prepared potatoes at 400°F for 15–20 minutes, shaking the basket halfway through. Work in batches so the fries have room to crisp. Toss the finished fries with truffle butter, Parmesan, parsley, and salt.
What to Serve with Truffle Fries
These Parmesan truffle fries can make a casual dinner feel like a restaurant meal. Serve them with:
- Crack Burgers or sliders
- Grilled steak or filet mignon
- Steak frites
- Grilled or roasted chicken
- Crab cakes or fried catfish
- Lobster rolls or shrimp sandwiches
- grilled cheese
- A crisp wedge salad
- Green beans or roasted vegetables
Make-Ahead Instructions
Cut the potatoes and place them in cold water up to 24 hours before baking. Cover the bowl and keep it refrigerated.
When you’re ready to cook, drain the potatoes and pat them completely dry before adding the olive oil. Bake and dress the fries immediately before serving for the best texture.
How to Store and Reheat Truffle Fries
Storage
Allow leftover fries to cool, then refrigerate them in an airtight container for up to 3 days.
Reheating
Spread the fries in a single layer on a baking sheet and reheat them in a 400°F oven until hot and crisp. You can also reheat them in an air fryer for a few minutes.
Avoid reheating the fries in the microwave because it can make them soft.
Freezing
Cooked fries dressed with truffle butter and Parmesan do not freeze particularly well. For the best flavor and texture, prepare and serve them fresh.
