Yard House Truffle Fries Recipe (Copycat Parmesan Truffle Fries)

This copycat Yard House truffle fries recipe gives you the same crispy, golden fries the restaurant tosses with white truffle oil, shredded Parmesan and fresh herbs. They cook in about 20 minutes in the air fryer (oven directions are below too), and you only need a handful of ingredients to get that steakhouse smell at your own table.

If you have ordered the Parm Truffle Fries at Yard House, you know what makes them different: they are light on the truffle, heavy on the Parmesan, and still crisp when you reach the bottom of the basket. Most homemade versions drown the fries in oil and lose the crunch. This one is built to keep it.

What Are Yard House Truffle Fries?

Yard House Parmesan Truffle Fries are thin, crispy fries finished with white truffle oil, Parmesan and herbs. The menu marks them vegetarian, and you can order them as an appetizer or swap them in as a side with a burger or sandwich.

Three things give them their flavor:

• White truffle oil. It is milder and more garlicky than black truffle oil, and a little goes a long way.
• Shredded Parmesan. Fine shreds cling to hot fries and melt just slightly.
• Fresh herbs. Parsley and a little thyme keep the fries from tasting heavy.

Why You’ll Love This Recipe

• True to the menu. White truffle oil, Parmesan and herbs. Nothing extra.
• Crispy without deep frying. The air fryer does the work with a tablespoon of oil.
• Ready fast. About 20 minutes of cook time, or less with frozen fries.
• Vegetarian. Just like the restaurant version.

Ingredients You’ll Need

• Russet potatoes: High starch means a crisp outside and fluffy middle. Cut them thin, about 1/4 inch.
• Olive oil or avocado oil: For crisping. Save the truffle oil for the end.
• Kosher salt: Season as soon as the fries come out.
• White truffle oil: Buy a small bottle. It loses its aroma once opened, so fresh matters more than fancy.
• Parmesan cheese: Finely shredded from a block. The shaker kind will not melt onto the fries.
• Fresh parsley and thyme: Finely chopped.

How to Make Yard House Truffle Fries in the Air Fryer

Step 1: Cut and soak. Cut the potatoes into thin fries and soak them in cold water for 30 minutes. This pulls out surface starch so they crisp instead of steam. It is the same soak I use for my Air Fryer Truffle Fries.

Step 2: Dry completely. Drain and pat the fries very dry with a clean towel. Wet fries will never get crispy.

Step 3: Oil and season. Toss the fries with the olive oil and half of the salt.

Step 4: Air fry. Preheat the air fryer to 380 degrees F. Arrange the fries in a single layer and cook for 15 to 20 minutes, shaking the basket every 5 minutes, until deep golden. Work in batches if needed.

Step 5: Toss while hot. Move the fries straight to a large bowl. Drizzle with the truffle oil, add the Parmesan, herbs and remaining salt, and toss until every fry is coated. Serve right away.

Oven Directions

Heat the oven to 425 degrees F. Spread the oiled fries on a parchment-lined sheet pan in a single layer and bake for 25 to 30 minutes, flipping halfway, until golden and crisp. Toss with the truffle oil, Parmesan and herbs as soon as they come out.

Frozen Fries Shortcut

Short on time? Use a 16-ounce bag of thin-cut frozen fries. Air fry at 400 degrees F for 12 to 15 minutes, shaking twice, then finish with the truffle oil, Parmesan and herbs. My Air Fryer Seasoned French Fries post walks through cooking frozen fries in more detail.

Pro Tips for the Best Truffle Fries

• Truffle oil goes on last. Heat cooks off the aroma. Never add it before air frying.
• Start with less. Two teaspoons is plenty for a full batch. You can add a few more drops at the table.
• Toss in a bowl, not on the plate. That is how the cheese and herbs stick to every fry instead of sitting on top.
• Do not crowd the basket. A single layer with space between fries is what keeps them crisp to the last one.
• Shred the Parmesan fine. Use the small holes of a box grater or a microplane.

What to Serve with Yard House Truffle Fries

At the restaurant these are a shareable starter, so I like to put them out next to my copycat Yard House Spinach Cheese Dip for a full Yard House appetizer night at home.

For dinner, they are the fries I make with Air Fryer Steak Frites, and they are just as good next to a burger. For dipping, try a quick malt vinegar aioli: stir 1/2 cup mayonnaise with 2 teaspoons malt vinegar and 1 small grated garlic clove. Ketchup works too.

Variations

• Garlic Parmesan truffle fries: Toss 2 cloves of minced garlic in with the cheese. This is closer to my Cheesecake Factory Copycat Parmesan Truffle Fries.
• No truffle oil: Skip it and add garlic butter for something like Red Robin Garlic Parmesan Fries.
• Extra truffle: Swap the kosher salt for truffle salt.
• Potato wedges or halves: Have leftover truffle oil? Use it on Air Fryer Truffle Potatoes.

Storage and Reheating

• Store: Refrigerate leftovers in an airtight container for up to 3 days.
• Reheat: Air fry at 375 degrees F for 3 to 5 minutes until hot and crisp. Skip the microwave, which makes fries soggy. Add a fresh pinch of Parmesan and a drop or two of truffle oil after reheating.

Yard House Truffle Fries FAQs

What is on Yard House truffle fries? The menu lists white truffle oil, Parmesan and herbs on crispy fries.

Are Yard House truffle fries vegetarian? Yard House marks them vegetarian, and this copycat has no meat. If you follow a strict vegetarian diet, look for Parmesan made without animal rennet.

White or black truffle oil? White. That is what Yard House uses, and it has a lighter, more garlicky flavor that suits fries.

Why are my truffle fries soggy? The potatoes were not dried well enough, the basket was crowded, or the truffle oil went on too heavy. Dry the fries, cook in batches and measure the oil.

Can I deep fry them instead? Yes. Fry the soaked, dried potatoes in 350 degree F oil for 4 to 6 minutes until golden, drain, then toss with the toppings.

Can I make them ahead? Cut and soak the potatoes up to a day ahead in the refrigerator. Cook and toss them just before serving.
