Truffle Fries is a restaurant staple side dish that's so easy to make at home! It's your favorite side of fries flavored with truffle oil and parmesan cheese and served with parmesan aioli.
You can make the fries in the fryer or an air-fryer. (It is best to prepare homemade fries but if you're in a rush, you can use frozen fries and cook it per package instructions.)
Parmesan Aioli:
Combine all of the ingredients in a small blender and pulse for a few seconds to combine. Set aside.
Prepare the fries:
Wash potatoes well and cut them into thin straws. Don't make them too thin or too thick or they won't cook right.
Place potatoes into a mixing bowl, rinse them a couple of times with COLD running water, and then, fill the bowl with cold water to cover them completely.
Let them soak about 30 minutes. Drain off all the water and fill the bowl again. Swish to rinse and drain off the water.
Spread potatoes on the towel and pat them dry.
Air-Fryer Method:
Toss potatoes with a little olive oil and a sprinkle of salt.
Spread the fries in one or two layers (one layer will require extra batches but will be extra crispy). Check your air fryer's recommendation first but I air-fry the fries at 400° for about 20 minutes, and make sure to toss them every 5 minutes.
Frying the French Fries (Double Frying):
Preheat the oil to 350° and prepare a wire rack lined with paper towels. Fry the potatoes in batches for 4-5 minutes, take them out, and place onto the paper towel.
Increase the heat of oil to 400° and fry them again until golden brown. Take them out of oil and onto a fresh paper towel. Sprinkle with salt.
If you need to keep fries warm, place them into the oven heated to 200°.
To Make Truffle Fries:
As soon as the fries is finished cooking, add them into a large mixing bowl.
Drizzle fries with truffle oil and sprinkle with parmesan cheese. Toss quickly and serve with the parmesan aioli!
