Sweet potato fries have surged in popularity, and for good reason: they are delicious, nutritious, and incredibly easy to prepare. When made with a mandolin, sweet potato fries reach new levels of crispiness and uniformity that frying or baking can only dream of achieving. To help you master the art of sweet potato fries using a mandolin, this comprehensive guide will walk you through everything from ingredient selection to cooking methods, ensuring a tasty and successful fry experience.
Why Choose Sweet Potatoes?
Sweet potatoes are not just an alternative to regular potatoes; they offer numerous health benefits that elevate them to superfood status. Here are some reasons to consider sweet potatoes over traditional fries:
- Rich in Nutrients: Sweet potatoes are packed with vitamins A, C, and numerous B vitamins, making them a nutritious choice.
- High in Fiber: The fiber content in sweet potatoes aids digestion and promotes a feeling of fullness.
With the nutritional benefits in mind, let’s delve into how to make sweet potato fries that are crispy and flavorful using a mandolin.
Choosing Your Sweet Potatoes
The first step in your sweet potato fry journey begins with the right selection of potatoes. There are many varieties available in the market, but for the best fries, consider the following:
Types of Sweet Potatoes
When choosing sweet potatoes, opt for those that are:
- Firm: Look for sweet potatoes that are hard to the touch and free of soft spots.
- Evenly Shaped: Uniformly shaped sweet potatoes will yield fries that cook evenly.
Organic vs. Conventional
You may also consider whether to purchase organic or conventional sweet potatoes. Organic sweet potatoes are grown without synthetic pesticides and fertilizers, making them a healthier option, although often more expensive.
Essential Tools and Ingredients
To create these irresistible fries, having the right tools on hand is critically important. Here’s what you’ll need:
Tools
- Mandolin Slicer: A high-quality mandolin slicer will help you achieve the perfect fry shape and thickness. Look for one with safety features to protect your fingers.
- Baking Sheet: A large, sturdy baking sheet or two for even baking.
- Parchment Paper: This will help prevent sticking and make cleanup easier.
- Mixing Bowl: A bowl for tossing your fries in oil and seasoning.
- Spatula: For flipping the fries halfway through cooking.
- Knife: A sharp knife for any necessary trimming or cutting.
Ingredients
To make sweet potato fries, you’ll need the following ingredients:
- Sweet Potatoes: Approximately 2 large or 3 medium-sized sweet potatoes.
- Cooking Oil: Olive oil, coconut oil, or avocado oil work well.
- Seasoning: Salt, black pepper, garlic powder, paprika, or any of your favorite spices.
Preparing Your Sweet Potato Fries
Now that you have your tools and ingredients, it’s time to prepare your sweet potato fries.
Step 1: Wash and Peel the Sweet Potatoes
Start by washing the sweet potatoes under cold water to remove dirt and impurities. After washing, peel them using a vegetable peeler. The skin is nutritious, but for fries, peeling is often preferred for texture and taste.
Step 2: Slice with the Mandolin
Using the mandolin, slice the sweet potatoes into thin, uniform strips. Aim for a thickness of about 1/4 inch for optimal crispiness. To use the mandolin safely:
- Adjust the blade to your desired thickness.
- Secure the sweet potato in the mandolin holder.
- Slowly slide the sweet potato across the blade, applying slight pressure.
- Take breaks if necessary and always use the hand guard.
You should end up with a large bowl full of perfectly sliced sweet potatoes.
Step 3: Rinse and Dry
To remove excess starch and help achieve maximum crispiness, rinse the sweet potato slices under cold water. After rinsing, spread the fries on a clean kitchen towel or paper towels and pat them dry. This step is essential for avoiding soggy fries.
Tossing and Seasoning
Now that your sweet potato fries are sliced and dried, it’s time to give them some flavor.
Step 4: Toss with Oil and Seasoning
In a mixing bowl, combine your sweet potato fries with 2-3 tablespoons of your chosen cooking oil. The oil is crucial for crispiness, so don’t skimp on this step. Next, add your chosen seasonings:
- Salt and Pepper: Start with a base of salt and pepper.
- Additional Spices: Consider adding garlic powder, paprika, cayenne pepper, or even parmesan cheese for extra flavor.
Gently toss the fries in the bowl until they are evenly coated with oil and seasoning.
Cooking the Fries
Now comes the moment of truth: it’s time to cook your sweet potato fries. There are two effective methods: baking and air frying. Each method has its unique advantages.
Baking Sweet Potato Fries
For baking, preheat your oven to 425°F (220°C). Here’s how to proceed:
Step 5: Baking Instructions
- Prepare the Baking Sheet: Line your baking sheet with parchment paper to prevent sticking.
- Spread Out Evenly: Arrange the fries in a single layer, ensuring they’re not touching. Overcrowding can lead to steam rather than crispiness.
- Bake: Place the sheet in the preheated oven. Bake for 20-25 minutes, flipping the fries halfway through to promote even cooking.
- Check for Doneness: The fries should be golden brown and crispy when done. Keep an eye on them to avoid burning.
Air Frying Sweet Potato Fries
If you’re using an air fryer, the process is even simpler.
Step 6: Air Frying Instructions
- Preheat Air Fryer: Preheat your air fryer according to the manufacturer’s instructions, usually around 375°F (190°C).
- Arrange Fries: Place the seasoned fries in the air fryer basket in a single layer. You may need to work in batches.
- Air Fry: Cook for about 15-20 minutes, shaking the basket halfway through for even cooking.
- Crispiness Check: They should be crispy and golden. If you prefer them crispier, add a few extra minutes.
Serving and Enjoying Your Sweet Potato Fries
Once your fries are cooked, it’s time to enjoy them. Here are some ideas for serving:
Dipping Sauces
Pair your sweet potato fries with various dipping sauces to enhance the flavor profile. Some suggestions include:
- Spicy Mayo
- Garlic Aioli
- Honey Mustard
- Guacamole
Accompaniments
Sweet potato fries can be served as a side dish to various meals, such as grilled chicken, steak, or burgers. They can also be enjoyed as a healthy snack.
Storing Leftover Sweet Potato Fries
If you happen to have leftovers (though unlikely), storing them properly is essential to maintaining their crispiness.
Step 7: Storing Instructions
- Cooling Down: Allow fries to cool completely after cooking.
- Pack Them Up: Store in an airtight container for up to 3 days in the refrigerator.
- Reheating Use: Reheat in the oven or air fryer to regain crispiness. Avoid microwaving, as it can make the fries soggy.

What is a mandolin, and why should I use it for sweet potato fries?
A mandolin is a versatile kitchen tool that allows you to slice vegetables uniformly in various thicknesses. Using a mandolin for sweet potato fries ensures that all the fries cook evenly, which is key to achieving that perfect crispy texture. Consistent slicing is difficult to achieve with a knife, especially with the irregular shapes of sweet potatoes, making the mandolin a valuable addition to your kitchen.
Additionally, mandolins often come with various attachments that let you achieve different cuts and shapes, from julienne to crinkle fries. This flexibility means you can explore a variety of preparations and presentation styles, making your sweet potato fries not just delicious but visually appealing as well.
How do I choose the right sweet potatoes for fries?
When selecting sweet potatoes, look for ones that are firm, smooth, and free from blemishes or cracks. The best sweet potatoes for frying are those that are uniform in size, as this will help them cook evenly. Varieties can differ, with some being starchier and others russet-like in texture, which can affect the crunchiness of your fries. Generally, younger, smaller sweet potatoes yield better results for fries.
You may also want to consider the color of the sweet potatoes. Orange-fleshed varieties, like the Beauregard, are the most common and offer a sweet flavor and fluffy texture when cooked. However, you could experiment with other varieties, such as purple or white sweet potatoes, for different tastes and textures, making your dish even more interesting.
What is the best way to season sweet potato fries?
Seasoning sweet potato fries can truly elevate their flavor, and there are countless combinations to explore. A simple mix of salt, pepper, and a touch of paprika or cayenne can enhance their natural sweetness beautifully. You can also experiment with garlic powder, onion powder, or smoked sea salt to add depth. It’s helpful to season the fries after cutting but before baking or frying, allowing the flavors to penetrate the potatoes.
For those who enjoy experimenting with flavors, consider trying herbs like rosemary or thyme for a fresh twist. Alternatively, you can create a sweet spice blend with cinnamon and nutmeg. Remember to toss the fries well after seasoning, ensuring every piece is coated. Just remember to balance your seasonings so that they complement but do not overpower the natural sweetness of the potatoes.
How can I achieve crispy sweet potato fries?
Achieving crispy sweet potato fries requires attention to both preparation and cooking methods. One effective technique is to soak the cut fries in cold water for about 30 minutes before cooking. This helps remove excess starch, which can lead to a soggy texture. After soaking, thoroughly dry the fries with paper towels to ensure that moisture doesn’t prevent them from crisping up during cooking.
When it comes to cooking, using a high temperature is crucial. Whether you choose to bake or fry, make sure your oven or oil is adequately preheated. If baking, spreading the fries in a single layer on a baking sheet and avoiding overcrowding will foster even cooking. For frying, ensure the oil is hot enough before adding the fries, as this will quickly seal the exterior and promote a crispy finish.
Can I make sweet potato fries ahead of time?
Yes, you can make sweet potato fries ahead of time, which can be a great time-saver for busy meals. One option is to slice and season the fries, then place them in an airtight container in the refrigerator for up to 24 hours before cooking. This method not only lets the seasoning meld but also makes it convenient to cook them right before serving.
Alternatively, for longer storage, you can freeze the fries after slicing. Lay them in a single layer on a baking sheet to freeze for a couple of hours, then transfer them to a freezer bag. When you’re ready to cook, you can bake or fry them straight from the freezer; simply adjust the cooking time as needed to ensure they become crispy and golden.
What are some good dipping sauces for sweet potato fries?
Sweet potato fries pair wonderfully with a variety of dipping sauces that can complement their rich and sweet flavor. A classic choice is spiced ketchup, where you can mix traditional ketchup with a touch of sriracha or smoked paprika for an exciting twist. Another popular option is a creamy ranch or garlic aioli, which offers a cool contrast to the warmth of the fries.
For a healthier alternative, consider a yogurt-based dip infused with herbs like dill or cilantro. You could also try a spicy tahini sauce for an exotic flair, combining tahini, lemon juice, garlic, and a pinch of cayenne. With so many options, you can easily tailor your dips to align with your personal taste preferences or the overall theme of your meal.
