Ingredients

For the Sweet Potato Fries

• 2 large sweet potatoes (about 650 g), scrubbed and cut into 1/2-inch sticks • 2 tbsp (30 ml) olive oil • 1 tbsp (8 g) cornstarch • 1 tsp (3 g) garlic powder • 1 tsp (3 g) smoked paprika • 1/2 tsp (1.5 g) dried oregano • 1/2 tsp (3 g) fine salt • 1/4 tsp (0.5 g) freshly ground black pepper

Optional Garnishes

• 1 tsp flaky sea salt • 1 tbsp fresh parsley, finely chopped

How to Make Extra Crispy Baked Sweet Potato Fries

1. Cut the sweet potatoes into uniform sticks about 1/2-inch thick to ensure even cooking.
2. Place the cut sweet potatoes in a large bowl, cover completely with cold water, and let soak for 30 minutes to remove extra surface starch.
3. Drain the water completely and lay the sweet potato sticks flat on paper towels to pat them thoroughly dry.
4. Preheat your oven to 425°F (220°C) and line a large baking sheet with parchment paper.
5. Transfer the dried sweet potatoes back into a clean, dry bowl.
6. Sprinkle the cornstarch over the sweet potatoes and toss well until every piece is lightly coated in a thin dust.
7. Pour the olive oil over the sweet potatoes, then add the garlic powder, smoked paprika, dried oregano, salt, and black pepper.
8. Toss everything together using your hands or tongs until the spices and oil evenly coat every fry.
9. Spread the sweet potato sticks onto the prepared baking sheet in a single layer, ensuring none of the pieces overlap or touch each other.
10. Bake at 425°F (220°C) for 15 minutes.
11. Remove the tray from the oven, flip each fry using a spatula, and return to the oven to bake for another 10 minutes until the edges are deep golden brown and crisp.
12. Remove from the oven, sprinkle with flaky sea salt and chopped parsley, and serve immediately with ketchup or your favorite dipping sauce.

Pro Tip

Crowding the baking sheet is the primary reason oven-baked sweet potato fries turn out soggy. When fries touch or sit on top of each other, they trap steam instead of roasting. Spread your sweet potatoes out with clear space between every piece, or split them across two separate baking sheets if needed.

Serving & Storage

Serve these fries piping hot fresh from the oven for the absolute best crunch. They pair exceptionally well with classics like garlic aioli, spicy mayo, or basic tomato ketchup. Try serving them alongside juicy beef burgers, grilled chicken sandwiches, or crisp veggie wraps.

Store leftover fries in an airtight container lined with a paper towel in the refrigerator for up to 3 days. Freezing is not recommended after baking, as thawed sweet potatoes lose their crisp texture.

Reheat leftovers in a single layer in a preheated oven at 400°F (200°C) or in an air fryer for 4 to 5 minutes until heated through and crisp again. Microwave reheating is not recommended, as it makes the fries soft and rubbery.

FAQs

Can I skip soaking the sweet potatoes in water?

Soaking removes excess starch, which is essential for getting a crisp exterior, so skipping this step will result in softer fries.

Why are my sweet potato fries soggy after baking?

Soggy fries usually happen if the sweet potatoes were not dried completely after soaking or if the baking sheet was overcrowded.

Can I cook these sweet potato fries in an air fryer?

Yes, air fry these in batches at 380°F (190°C) for 12 to 15 minutes, shaking the basket halfway through.
