I’m absolutely obsessed with these sweet potato fries, and I know you will be too!
They’re the perfect balance of sweet and savory with that irresistible crispy exterior.
But what makes them truly special is how versatile they are – you can customize the seasonings to match any meal.
My family requests these fries at least once a week because they’re not only delicious but also more nutritious than regular fries.
Sweet potatoes are packed with vitamins, fiber, and antioxidants, making this a snack you can feel good about serving.

Simple Ingredients
One of the best things about this recipe is that it requires just a few simple ingredients that you probably already have in your kitchen. However, each ingredient plays an important role in achieving that perfect crispy texture.
- Sweet Potatoes: Look for firm, smooth potatoes with uniform color. Medium-sized ones work best for even cooking.
- Cornstarch: The secret ingredient! This helps absorb moisture and creates that crispy exterior we all crave.
- Oil: I prefer olive oil, but canola or avocado oil work great too. The key is using just enough without overdoing it.
- Salt: Fine sea salt or kosher salt works best for even distribution.
- Seasonings: My basic mix includes garlic powder, black pepper, and paprika, but you can customize to your taste.
Flavor Your Fries: Seasoning Combinations
While the basic recipe is delicious on its own, I love experimenting with different seasoning combinations. Here are some of my favorite flavor profiles that you can try!
| Seasoning Style | Ingredients | Best Paired With |
| Classic | Salt, pepper, garlic powder | Burgers, sandwiches |
| Spicy | Salt, cayenne pepper, paprika, garlic powder | Mexican dishes, spicy burgers |
| Sweet & Savory | Salt, cinnamon, brown sugar | Chicken dishes, as a side for brunch |
| Herb Garden | Salt, rosemary, thyme, garlic powder | Roasted meats, Mediterranean dishes |
| Smoky | Salt, smoked paprika, cumin, garlic powder | BBQ dishes, pulled pork |

How to Cut Sweet Potato Fries
The way you cut your sweet potatoes makes a huge difference in how crispy your fries turn out. I’ve learned through many batches that thinner, uniformly-sized fries crisp up much better than thick ones.
Step-by-Step Cutting Guide
- Peel the sweet potato (optional, but I prefer peeled for this recipe).
- Cut off both ends to create flat surfaces.
- Stand the potato on one flat end and slice it in half lengthwise.
- Place each half flat-side down and cut into 1/4-inch thick slabs.
- Stack the slabs and cut them into 1/4-inch sticks.
- Try to keep all fries approximately the same size for even cooking.
Remember, the thinner you cut them (about 1/4 inch is perfect), the crispier they’ll get. But don’t go too thin, or they’ll burn before cooking through!
The Secrets to Extra Crispy Sweet Potato Fries
Let’s be honest – getting truly crispy sweet potato fries at home can be challenging. Because of their high moisture content, sweet potatoes tend to get soggy easier than regular potatoes.
But don’t worry! After years of testing, I’ve discovered these game-changing tips that make all the difference.
The Cornstarch Trick
Tossing your cut fries in a light coating of cornstarch before adding oil creates a thin layer that absorbs moisture and crisps up beautifully. I use about 1-2 tablespoons per pound of potatoes.
Don’t Overcrowd the Pan
This is crucial! Arrange fries in a single layer with space between them. If they’re too close, they’ll steam instead of crisp. Use two baking sheets if needed.
High Heat is Your Friend
Bake at 425°F (220°C) for optimal crispiness. Lower temperatures won’t create that perfect exterior, while higher temps risk burning before the centers cook.
Pro Tip: The Soaking Debate
You may have heard about soaking sweet potato fries in cold water before baking. I’ve tested this extensively and found that while it works great for regular potatoes, the results are mixed for sweet potatoes. If you have time, soak them for 30 minutes, then pat VERY dry before the cornstarch step. But if you’re short on time, the cornstarch trick alone works wonders!
Two Ways to Cook: Oven vs. Air Fryer
Both methods produce delicious results, but there are some key differences. I personally love both for different reasons!
| Feature | Oven Method | Air Fryer Method |
| Cooking Time | 25-30 minutes total | 12-15 minutes total |
| Crispiness Level | Good (excellent with cornstarch) | Excellent |
| Batch Size | Large (full baking sheet) | Small (multiple batches needed) |
| Temperature | 425°F (220°C) | 375°F (190°C) |
| Oil Amount | 1-2 tablespoons per pound | 1 tablespoon per pound |
Step-by-Step Recipe Instructions
Oven Method
- Preheat your oven to 425°F (220°C). Line two baking sheets with parchment paper.
- Prepare the sweet potatoes by peeling and cutting them into 1/4-inch thick fries.
- Place the cut fries in a large bowl and sprinkle with 1-2 tablespoons of cornstarch. Toss until all fries are lightly coated.
- Drizzle with olive oil (about 1-2 tablespoons per pound) and toss again until evenly coated and no dry cornstarch remains.
- Season with salt and any desired spices, tossing to distribute evenly.
- Arrange fries in a single layer on the prepared baking sheets, making sure they don’t touch.
- Bake for 15 minutes, then flip each fry and rotate the pans in the oven.
- Bake for another 10-15 minutes until the fries are crispy and golden brown.
- Serve immediately for maximum crispiness!
Air Fryer Method
- Preheat your air fryer to 375°F (190°C) if your model requires it.
- Prepare the sweet potatoes by peeling and cutting them into 1/4-inch thick fries.
- Place the cut fries in a bowl and sprinkle with 1 tablespoon of cornstarch. Toss until lightly coated.
- Drizzle with 1 tablespoon of olive oil and toss until evenly coated and no dry cornstarch remains.
- Season with salt and desired spices, tossing to distribute evenly.
- Place a single layer of fries in your air fryer basket, making sure they don’t overlap too much.
- Cook for 6-7 minutes, then shake the basket or flip the fries.
- Cook for another 6-7 minutes until crispy and golden brown.
- Repeat with remaining fries in batches as needed.
Perfect Dipping Sauces for Sweet Potato Fries
While these fries are delicious on their own, the right dipping sauce can take them to the next level! Here are some of my favorite pairings that complement the natural sweetness of the potatoes.
Spicy Sriracha Mayo
Mix 1/4 cup mayonnaise with 1-2 teaspoons sriracha sauce and a squeeze of lime juice. The creamy heat pairs perfectly with the sweet fries.
Honey Mustard
Combine 2 tablespoons Dijon mustard, 1 tablespoon honey, and 1 tablespoon mayonnaise. This sweet-tangy sauce is always a crowd-pleaser!
Garlic Aioli
Mix 1/4 cup mayonnaise with 1 minced garlic clove, 1 teaspoon lemon juice, and a pinch of salt. Simple but incredibly flavorful.
What to Serve with Sweet Potato Fries
These versatile fries pair beautifully with so many main dishes! Here are some of my favorite combinations that make for a complete and satisfying meal.
Perfect Pairings
- Burgers: The sweetness of the fries balances perfectly with a savory burger. Try them with turkey or veggie burgers for a healthier meal.
- Sandwiches: Elevate your lunch with these fries alongside a grilled cheese or club sandwich.
- Grilled Meats: They’re the perfect side for grilled chicken, steak, or fish.
- Salads: Balance a fresh salad with these fries for a satisfying lunch.
- Breakfast: Yes, really! Try them with eggs and avocado for a delicious brunch.

Storage and Reheating Tips
Sweet potato fries are definitely best enjoyed fresh out of the oven or air fryer. However, if you have leftovers or want to prep ahead, here’s how to store and reheat them while maintaining as much crispiness as possible.
Storage Instructions
- Refrigerator: Allow fries to cool completely, then store in an airtight container for up to 3-4 days.
- Freezer: For longer storage, freeze cooled fries in a single layer on a baking sheet, then transfer to a freezer bag. They’ll keep for up to 3 months.
- Make-Ahead Prep: You can cut the sweet potatoes up to 2 days in advance. Store them in water in the refrigerator, then drain and thoroughly pat dry before cooking.
Best Reheating Methods
- Oven: Preheat to 400°F (200°C) and spread fries on a baking sheet. Reheat for 5-10 minutes until crispy again.
- Air Fryer: My favorite method! Reheat at 350°F (175°C) for 3-5 minutes until crispy.
- Avoid Microwave: This will make your fries soggy. If you must use it, place a paper towel underneath to absorb moisture.
Important Note
Sweet potato fries will never be quite as crispy when reheated as they are fresh. For the best experience, I recommend making only what you plan to eat right away. However, the reheating methods above will give you the best possible results with leftovers!
Nutritional Benefits of Sweet Potato Fries
One of the reasons I love making sweet potato fries is that they’re not just delicious – they’re also packed with nutrients! Here’s why you can feel good about choosing sweet potatoes over regular potatoes.
Health Benefits
- Rich in Vitamin A: Sweet potatoes are loaded with beta-carotene, which your body converts to vitamin A – essential for vision, immune function, and skin health.
- Good Source of Fiber: They contain both soluble and insoluble fiber, supporting digestive health.
- Antioxidant Properties: The vibrant orange color comes from antioxidants that help fight inflammation.
- Complex Carbohydrates: Sweet potatoes provide sustained energy without the blood sugar spikes of simple carbs.
- Lower Glycemic Index: They have a lower GI than white potatoes, meaning they won’t raise blood sugar as quickly.

Frequently Asked Questions
Why aren’t my sweet potato fries getting crispy?
This is the most common issue! There are several possible reasons: 1) Your fries might be cut too thick – aim for 1/4 inch thickness, 2) The oven temperature might be too low – 425°F is ideal, 3) The fries might be overcrowded on the baking sheet – they need space, or 4) You might be using too much oil, which can make them soggy. Try the cornstarch trick mentioned in the recipe for extra crispiness!
Do I need to peel sweet potatoes before making fries?
It’s completely up to you! The skin contains additional nutrients and fiber. If you choose to leave it on, just make sure to scrub the potatoes thoroughly. I personally prefer to peel them for a more uniform texture, but both ways work great.
Can I make these without oil for an oil-free diet?
While some oil helps achieve crispiness, you can reduce it significantly. Try using just 1-2 teaspoons and an oil sprayer for even distribution. For completely oil-free, you can use parchment paper and a very light spritz of water before adding seasonings, but they won’t get as crispy.
Why do you add cornstarch to the sweet potato fries?
Cornstarch is my secret weapon for crispy fries! It absorbs excess moisture from the sweet potatoes and creates a thin, crispy exterior when baked. If you don’t have cornstarch, arrowroot powder works as an alternative, though the results might be slightly less crispy.
Can I make these in advance for a party?
Sweet potato fries are best served immediately after cooking. However, you can prep them ahead by cutting the potatoes up to 2 days in advance (store in water in the refrigerator, then pat very dry before cooking). For parties, I recommend having everything ready to go and popping them in the oven just before serving.
