Why You'll Love This Recipe
- Better Than Take Out: Making these at home allows you to control the quality of ingredients. Not only do they end up tasting better, but they are better for you!
- Super Simple: This is one of the easiest side dishes you will ever make. These fries are on the weekly rotation at our house!

Ingredients
- Sweet Potatoes: Sweet potatoes are a great source of carbohydrates and are a good source of potassium, beta carotene, Vitamin C, Vitamin B, Vitamin A, Magnesium, and fiber. You can use any variety of sweet potato that you like such as Beauregard, Jewel, Garnet, or Japanese sweet potatoes.
- Avocado Oil: Avocado oil is fantastic when cooking at high temperatures. You could also use Extra Virgin Olive Oil if you are in a pinch, however, it’s not ideal for cooking at high temperatures. Coconut Oil would also work and will add a touch of extra sweetness to the fries.
- Sea Salt: Pink Himalayan sea salt is my favorite.
- Dried Rosemary: You can substitute it with other herbs or Italian seasoning. Fresh rosemary also works well.
- Flakey Sea Salt: Don’t sleep on the flakey sea salt. This is added right after the fries come out of the oven for even more flavor and crunch.
- Truffle Oil: Make sure you read the labels when shopping for truffle oil. You want to ensure that the truffle oil is high quality and is made from real truffles and Olive Oil. I’m a big fan of Truff.
- Grated Parmesan Cheese (Optional): Try making parmesan truffle fries by grating some fresh parmesan cheese directly onto your fries as they come out of the oven.

Substitutions And Variations
Feel free to mix and match these substitutions and variations to customize to your taste preferences and dietary needs. Experimenting with different flavors and ingredients is part of the fun of cooking, so don't be afraid to get creative!
- Different Types of Potatoes: If you don't have sweet potatoes on hand, you can make regular fries by using russet or Yukon gold potatoes.
- Truffle Salt: Instead of truffle oil, you can sprinkle truffle salt over the fries before baking for a more subtle truffle flavor.
- White Truffle Version: If you don't like black truffle oil and want something slightly milder, you can drizzle a little bit of white truffle oil on the sweet potato fries.
- Duck Fat: Try making duck fat sweet potato fries by coating the potatoes in duck fat instead of avocado oil.
- Cheese Toppings: Sprinkle-grated Parmesan, Pecorino Romano, or Gruyère cheese over the fries during the last few minutes of baking for a cheesy twist.
- Spice Blends: Create your own spice blend by mixing truffle oil with garlic powder, onion powder, paprika, or chili powder for a spicy kick.
- Sweet and Savory: For a sweet and savory flavor combination, drizzle the fries with honey or maple syrup before baking and sprinkle with sea salt after cooking.
- Balsamic Reduction: Drizzle balsamic reduction over the fries before serving for a tangy and sweet contrast to the rich truffle flavor.
- Fresh Herbs: Garnish the hot fries with chopped fresh parsley, chives, or cilantro for a pop of color and freshness.
How To Make Truffle Sweet Potato Fries
This is an overview with step-by-step photos. Full ingredients & instructions are in the recipe card below.
Step 1. Wash and peel the sweet potatoes. Cut each potato in half lengthwise, then cut them again into ¼ - ½ inch thick fries.
Step 2. Soak the cut fries in a large bowl of ice water for 30 - 60 minutes. Dry the potato wedges well using some cloth or paper towels.
Step 3. Preheat your oven to 400 degrees f. Add the dried potato wedges to a parchment-lined baking sheet, then add the oil, salt, and rosemary. Toss to combine.
Step 4. Arrange the fries in a single layer on the large baking sheet, ensuring they don’t touch or overlap for even cooking. Bake for 15 minutes, then carefully flip each fry with a fork. Return to the oven and bake for an additional 15 minutes, or until the fries are golden brown with crispy edges.
Step 5. While the fries are still hot, drizzle them with a teaspoon of truffle oil and add a generous pinch of flakey sea salt.
Nadia's Expert Tips And Notes
- For best results don’t skip the ice bath! Soaking the potatoes in cold water is a critical step in getting the right texture for the sweet potato fries! This process will help remove excess starch from the potatoes which will help ensure you have crispy fries.
- Cut the fries evenly to ensure they cook at the same rate.
- Don’t overcrowd the baking sheet—space helps them crisp up.
- Use fresh, high-quality truffle oil for the best flavor.
