Ingredients For Crispy Sweet Potato Fries

To make these crispy homemade sweet potato fries, gather the following ingredients:

• 2 large sweet potatoes
• 2 tablespoons cornstarch (secret to crispiness!)
• 2 tablespoons olive oil
• 1 teaspoon paprika
• 1 teaspoon garlic powder
• ½ teaspoon salt (plus more to taste)
• ½ teaspoon black pepper
• ½ teaspoon cayenne pepper (optional for a spicy kick)

Step-by-Step Instructions

1. Prepare the Sweet Potatoes

Preheat your oven to 425°F (220°C). Line a large baking sheet with parchment paper to prevent sticking.

Wash and peel the sweet potatoes, then cut them into evenly-sized fries. Aim for ¼-inch thick sticks to ensure even cooking. If they are too thick, they won’t crisp up properly.

2. Soak for Extra Crispiness

One of the best tricks for crispy baked sweet potato fries is soaking them in cold water for at least 30 minutes. This removes excess starch, preventing them from becoming soggy. After soaking, drain the fries and pat them completely dry using a clean kitchen towel.

3. Coat with Cornstarch and Seasonings

Place the dried sweet potato fries in a large bowl. Sprinkle cornstarch over them and toss to coat evenly. The cornstarch acts as a crisping agent, absorbing moisture and helping create a crunchy texture.

Next, drizzle olive oil over the fries and add the paprika, garlic powder, salt, black pepper, and cayenne pepper. Toss until each fry is evenly coated with seasoning.

4. Arrange for Optimal Crispiness

Spread the fries in a single layer on the prepared baking sheet. Make sure they are not overcrowded—otherwise, they will steam instead of crisping up. For best results, leave a little space between each fry.

5. Bake to Perfection

Place the baking sheet in the preheated oven and bake for 20 minutes. After 20 minutes, take them out and flip each fry using tongs. This ensures even crisping on all sides.

Continue baking for another 15-20 minutes, or until the fries turn golden brown and crispy.

6. Serve and Enjoy

Remove the fries from the oven and let them cool for a few minutes before serving. Sprinkle extra salt if needed, and serve with your favorite dipping sauce.

Nutritional Information & Health Benefits

Sweet potato fries aren’t just a delicious snack—they’re also packed with essential nutrients and health benefits. When baked instead of fried, they become a healthier alternative to traditional fries while still delivering a satisfying crunch. Here’s a look at the nutritional value of these crispy fries, as well as the incredible health benefits they provide.

Health Benefits of Sweet Potato Fries

• Rich in Antioxidants – Sweet potatoes contain beta-carotene, which supports eye health and immune function.

Expert Tips for Extra Crispy Fries

1. Use High Heat

A hot oven (425°F or higher) ensures that the fries cook quickly and develop a crispy texture without burning.

2. Don’t Skip the Cornstarch

Cornstarch is the secret ingredient that helps absorb moisture and create a crispy exterior.

3. Spread Fries in a Single Layer

Overcrowding leads to steaming instead of crisping, so give the fries plenty of space.

4. Use Parchment Paper

This prevents sticking and helps achieve an evenly baked texture.

5. Flip Halfway Through

Turning the fries during baking ensures even cooking and crispiness on all sides.

Common Mistakes to Avoid

❌ Skipping the soaking step – Leads to soggy fries. Soak for at least 30 minutes.
❌ Cutting fries too thick – Thicker fries don’t crisp up well. Stick to ¼-inch thickness.
❌ Not using cornstarch – This is the secret ingredient for crunch!

Dipping Sauce Ideas

Pair your crispy sweet potato fries with these delicious dips:

• Garlic Aioli – A creamy and garlicky dip for extra flavor.
• Spicy Sriracha Mayo – Adds a spicy kick to complement the sweetness.
• Honey Mustard – A perfect balance of sweet and tangy.
• Avocado Ranch – Creamy and refreshing.
