How do you cut sweet potato fries?
You don’t need a fancy fry cutter to cut sweet potatoes for fries. Peel the sweet potatoes, trim the ends, and cut them in half lengthwise. Lay the halved potato on its flat side and cut into about 1/3-inch pieces, then slice those pieces into about 1/3-inch strips, taking care to make sure the fries are as close to the same thickness as possible for the perfect french fry shapes!
How long to bake sweet potato fries
Bake your sweet potato fries at 425° for 32-38 minutes, flipping about halfway through.
SUBSTITUTIONS FOR SWEET POTATO FRIES
Sweet Potatoes – USE sweet potatoes that are about the same diameter throughout the length of the potato with no weird shaped knots or lumps. This will allow you to cut even-sized fries which will help them cook evenly!
Oil – You will want to use an oil that can tolerate high heat for this recipe. Refined olive oil is better at high heat, however, even EVOO can tolerate baking at 425 F. Avocado oil is another neutral flavored cooking oil that will work well for this temperature.
Cooking Oil Spray – The cooking oil spray is used to add just a light coat of oil after the fries have been placed on the pan (too much oil can make the fries soggy). I had the best results using a combination of oil and cooking oil spray in this recipe; however, you can an additional 2 teaspoons of oil to the fries while they are in the Ziploc bag and omit the cooking oil spray. Traditional cooking spray (Pam) is not recommended because it’s made with vegetable oil. Select a clean label cooking spray made with avocado oil or olive oil. You can also use a good olive oil sprayer that you fill yourself. The more evenly the oil disperses the better. Here’s the avocado oil spray we like.
Starch – The starch absorbs some moisture from the potatoes, giving the fries a light, crispy texture. You can use Tapioca starch, potato starch, or cornstarch.
What type of sweet potato should I use to make sweet potato fries?
Sweet potatoes with a red or orange skin, like Garnet or Jewel are great options to use for sweet potato fries because they have the traditional orange flesh and sweet taste.
For something a little different, you can use tan or purple skin varieties (like Japanese, Sweet Hanna, or Purple) which are more starchy and a little less sweet.
How to serve Oven Baked Sweet Potato Fries
These sweet potato fries go with pretty much anything! We love to serve them with:
Best Sauces for Sweet Potato Fries
Sriracha Dipping Sauce – Combine ¼ cup Greek yogurt, ¼ cup avocado oil mayo, and 1 tbsp sriracha for a creamy sauce with a kick.
Healthy Ranch Dressing – Mix together ¼ cup Greek yogurt, ¼ cup of mayo, 1 tsp garlic powder, 1 tsp fresh lemon juice, 1 tbsp fresh minced dill, 1 tbsp fresh minced chives, ½ tsp honey, and salt to taste for a healthier version of this favorite.
Weigh your potatoes: Because sweet potatoes can vary in size, it is helpful to weigh them after they have been peeled and cut into fries. You will need about 900 grams of fries for the amount of starch and oil used in this recipe.
Cut evenly: When cutting the fries, make sure they are all about the same thickness. Thinner/smaller fries will burn more easily.
Use parchment paper to keep the fries from sticking to the pan and help pull moisture away from them as they cook.
Avoid cooking the sweet potatoes alongside another vegetable, especially something that emits moisture when roasting (like broccoli or mushrooms).
Separate the sweet potatoes so that no fries are touching, and they are all in a single layer.
Flip every fry individually to ensure all are flipped and none are touching. This takes more time but really helps to get them crispy.
Watch the fries and rotate the pan if needed to prevent some fries from burning.
Check on the fries regularly to prevent them from burning. The sugars in sweet potatoes cause them to burn more quickly than regular potatoes, especially at the higher temperature required to get them crispy.
Can I make air fryer sweet potato fries?
This recipe will work similarly in the air fryer as it does in the oven as long you are using an air fryer with trays/racks instead of a basket.
Most air fryers will not accommodate the full recipe so you will most likely need to halve (or even quarter) the recipe to ensure the fries are in a single layer when baking.
Bake at 425° for 35-40 minutes, but check regularly to prevent burning, especially if your air fryer tends to cook things quickly.
Sweet Potato Fries (Oven Recipe) FAQs
Sweet potato fries might not get crispy due to excess moisture, improper thickness, overcrowding on the baking sheet, inadequate oil coating, low baking temperature, or not baking long enough. To achieve crispiness, ensure you toss them in the tapioca starch, cut them uniformly, space them out on the baking sheet, use enough oil, bake at a high temperature, and give them enough time to cook until golden brown.
Your fries may have too much moisture, be too large, or not be cooked at the right temperature or baked long enough to get nice and golden brown.
No, sweet potatoes and yams are not the same. They are both root vegetables; however, sweet potatoes are typically orange with a sweeter taste, while yams are more starchy, can be white or purple, and are less sweet.
Sweet potato fries are generally considered healthier than regular potato fries because they are lower in calories and fat, and have a lower glycemic index. They are also a good source of vitamins, fiber, and antioxidants.
Crispy Sweet Potato Fries storage
Storing: These baked sweet potato fries work best when enjoyed fresh. If you don’t need 4 servings of fries, consider halving the recipe. Leftover sweet potato fries can be stored in the fridge in an airtight container for up to 3 days, but they will soften as soon as they are stored.
Freezing: We don’t recommend freezing these baked sweet potato fries. They will be very soggy and never get as crispy once frozen!
Reheating: Reheating these fries will work best in the oven or air fryer. They will not get quite a crispy as the first time, but it will be much better than reheating in the microwave. Watch carefully to prevent burning since they are already fully cooked.
Homemade Sweet Potato Fries (Oven Recipe)
- Preheat the oven to 425 F. Line 2 large sheet pans with parchment paper and set aside.
- Peel the sweet potatoes, trim the ends and cut them in half lengthwise. Lay the halved potato on its flat side and cut into about 1/3-inch pieces, then slice those pieces into about 1/3-inch strips, taking care to make sure the fries are as close to the same thickness as possible.
- Add the fries to a Ziploc bag. Add the starch to the bag, seal and shake evenly coating all the fries.
- Add the oil, garlic powder and sea salt to the bag, seal and shake until all the fries are lightly coated.
- Divide the fries between the lined sheet pans ensuring no fries are touching. Small/thinner fries should be placed towards the inside/middle of the pan because they will cook too quickly if placed on the edges.
- Spray the fries lightly with cooking spray before putting them in the oven. Bake for about 32-38 minutes. Flip the fries after about 18 minutes, making sure that no fries are touching after you have flipped them. If you notice any fries getting overcooked towards the edges you can move these to the inside of the pan.
- After the fries are fully cooked, crack the oven door and turn off the heat, allowing the fries to cool partially in the oven for about 10 minutes: Remove from the oven and serve immediately.
