Crispy Sweet Potato Fries

About This Recipe

Sweet potato fries deliver a caramelized, naturally sweet alternative to the standard spud, but their high sugar and moisture content make crispiness a challenge. The trick is a light coating of cornstarch, plenty of space on the pan, and a hot oven. Cut into even batons, tossed with oil and a smoky-sweet spice blend, then roasted on a preheated sheet, they emerge with crisp edges and creamy interiors. A sprinkle of salt the moment they leave the oven locks in seasoning. Served with a chipotle or maple-mustard dipping sauce, they make an irresistible snack or side. Soaking the cut fries first draws out excess starch for better browning.

Ingredients

Serves 4

• 2 lbssweet potatoes(peeled)
• 1 tbspcornstarch
• 2 tbspolive oil
• 1 tspsmoked paprika
• 0.5 tspgarlic powder
• 0.25 tspcayenne pepper
• 1 tspkosher salt
• 0.25 tspblack pepper

Instructions

1. 1

   Cut even fries

   Slice the sweet potatoes into batons about 1/4 inch thick and as uniform as possible. Even sizing ensures they cook at the same rate so none burn while others stay raw.

   Thinner fries crisp better than thick ones.

2. 2

   Soak and dry

   Soak the cut fries in cold water 30 minutes to draw out surface starch, then drain and dry thoroughly with towels. Dry fries are essential; any moisture steams them instead of crisping.

3. 3

   Coat with cornstarch

   Toss the dried fries with cornstarch in a bowl until lightly dusted. This thin layer is the single biggest factor in achieving crisp, golden edges on sweet potatoes.

4. 4

   Season and oil

   Drizzle with olive oil and add paprika, garlic powder, cayenne, and pepper. Toss until evenly coated. Hold the salt for after baking to avoid drawing out moisture during roasting.

5. 5

   Preheat the pan

   Heat the oven to 425F with a baking sheet inside. Arranging fries on a hot pan jump-starts browning and prevents sticking, much like a restaurant fryer.

   Use two pans so the fries never touch.

6. 6

   Roast in a single layer

   Spread the fries in a single layer with space between each, then roast 15 minutes. Flip and roast another 10-15 minutes until the edges are deeply browned and crisp.

7. 7

   Salt and serve

   Sprinkle with kosher salt the moment they leave the oven and let them rest 2 minutes to firm up. Serve hot with your favorite dipping sauce.

Variations

• •

  Toss with cinnamon and a drizzle of maple syrup for a sweet version.

• •

  Add grated Parmesan and chopped rosemary in the last 5 minutes of roasting.

• •

  Make them in an air fryer at 400F for 12-15 minutes, shaking the basket halfway.

• •

  Coat with a Cajun spice blend for a spicier, savory profile.

Storage

Sweet potato fries are best eaten fresh and lose their crisp quickly. Refrigerate leftovers up to 2 days and re-crisp in a hot oven or air fryer rather than a microwave.
