Delicious truffle fries first baked in the oven then flavored with truffle oil and seasoned with truffle salt.

I have a list of foods that I consider addictive. Those are the ones that I can eat until pretty much nothing is left over. These truffle fries are definitely on that list, and pretty high. It takes a bit of work to make them, but these fries are so good that it completely makes it worth it.

The first time I made them we liked them so much that what was meant to be a side dish disappeared in the blink of an eye before the main dish was barely touched. I had to make a second batch an hour later because everyone was begging for more of those little heavenly sticks.

What are truffle fries?

Truffle fries are French fries, baked or fried, that are flavored with truffle oil or seasoned with truffle salt.

How to make truffle fries?

Making truffle fries is super simple. You prepare the fries either by baking, deep-frying or air frying them. The fries are then flavored with truffle oil.

You should never use truffle oil for cooking as delicate truffle oils will get destroyed and the desirable aroma will vanish. You should only use truffle oil for finishing your dish. What this means is that the fries need to be baked first, then flavorize with truffle oil and/or truffle salt.

Another thing to keep in mind is that, like with any spice or seasoning, a little goes a long way. A little drizzle is all that’s necessary in most cases.

What truffle oil to use for truffle fries?

I cannot emphasize it enough – to make truffle fries that taste great you must spring for good quality truffle oil. Some truffle oils are artificially scented with truffle flavor. Those are the ones to avoid. Instead, what you want is good quality olive oil infused with real black or white truffles.

They say that the best way to tell good truffle oil is when you see bits of truffles floating in the oil. This is the one to get if you are serious about your truffle fries or any dish you want to flavor with it. Sure, it costs more but you will appreciate the real flavor.

Another way to add truffle flavor to fries

You may have seen it already in both specialty stores and even large supermarkets. It’s called black truffle sea salt. It’s your typical sea salt mixed with bits of black truffle. Truffle bits release aromatic oils which get absorbed by the salt and make it smell like truffles. Ever since I tried I’ve become crazy about the smell of truffles and use every opportunity to add umami flavor to my foods.

You can use this truffle salt to add flavor to the truffle fries. I use a combination of both, this gives the best flavor in my opinion. But either on its own will work too.

I used my favorite method for making baked fries – quick high heat baking at 450F . With this method, I always get excellent browning and flavor.

I like cutting the potatoes about 1/2" thick as that way I get good browning and a soft, creamy interior. If you want your fries crispier, cut them thinner.
Also, do not overcrowd the potatoes. When overcrowded, they bake longer and don't crisp up too well.
