About the Ingredients

Sweet Potatoes

These vibrant roots are packed with vitamins and minerals, providing a nutritious base for our fries. Their natural sweetness pairs wonderfully with savory spices.

Olive Oil

This healthy fat not only helps to crisp the fries but also adds a rich flavor that complements the sweetness of the potatoes.

Garlic Powder

A staple in many kitchens, garlic powder brings a warm, aromatic essence that elevates the fries from simple to sensational.

Paprika

Whether you choose smoked or sweet, paprika adds a lovely color and a hint of earthiness, enhancing the overall taste profile.

Salt

Essential for bringing out the natural flavors, a sprinkle of salt is a must for any fry recipe.

Black Pepper

This common spice adds a subtle heat that balances the sweetness of the potatoes, giving the fries a well-rounded flavor.

Cornstarch

While optional, cornstarch is a secret weapon for achieving that extra crunch, making your fries irresistibly crispy!

Tips & Tricks

Soak for Success

Soaking the sweet potato fries in cold water for 30 minutes helps to remove excess starch, resulting in a crispier texture.

Don’t Crowd the Pan

Spread the fries in a single layer on the baking sheet. Overcrowding can lead to steaming instead of crisping.

Flip Halfway

Flipping the fries halfway through the baking time ensures even cooking and browning on all sides.

Adjust Cook Time

Ovens vary, so keep an eye on your fries as they bake. You want them golden brown and crispy, but not burnt!

Season to Taste

Feel free to experiment with different spices or herbs to customize the flavor to your liking!

Pro Tips

  • Use High Heat: Baking at 425°F gives the fries the heat they need to become perfectly crispy.
  • Pat Dry Thoroughly: After soaking, make sure to dry the fries well before tossing them in oil and seasonings.
  • Try Different Potatoes: Yukon gold or russet potatoes can also be used for a different flavor and texture.
  • Serve Immediately: For the best crunch, serve the fries right after baking; they tend to soften as they cool.

Step-by-Step Instructions

Preheat the Oven

Start by preheating your oven to 425°F (220°C) and placing a baking sheet inside to heat up, which helps achieve that crispy texture.

Prepare the Sweet Potatoes

Peel the sweet potatoes if desired, then cut them into 1/4-inch thick fries for even cooking.

Soak the Fries

Soak the cut fries in cold water for 30 minutes. This step is key for removing excess starch and achieving crispiness.

Season and Coat

After soaking, drain and pat the fries completely dry. Toss them in olive oil, garlic powder, paprika, salt, and pepper. If using, add cornstarch for extra crunch.

Bake to Perfection

Remove the hot baking sheet from the oven and spread the fries in a single layer. Bake for 25-30 minutes, flipping halfway through, until they’re golden and crispy.

Delicious Variations

Sweet and Spicy

Add a pinch of cayenne pepper or chili powder to the seasoning mix for a spicy kick that balances the sweetness of the potatoes.

Herb-Infused

Mix in dried herbs like rosemary or thyme for a fragrant twist that adds an aromatic flair to your fries.

Cheesy Delight

Sprinkle grated Parmesan cheese over the fries in the last 5 minutes of baking for a savory, cheesy crust.

How to Store Crispy Oven Baked Sweet Potato Fries

Refrigerator

Store leftover fries in an airtight container in the refrigerator for up to 3 days.

Freezer

For longer storage, freeze the fries in a single layer on a baking sheet, then transfer to a freezer bag for up to 2 months.

Reheating

Reheat in the oven at 400°F (200°C) for about 10 minutes to regain their crispy texture.

Frequently Asked Questions
