1

Prep the Oven

Heat your oven to 425°F and grab a baking sheet. Line it with parchment paper so your fries won’t stick.

2

Clean the Potatoes

Scrub those sweet potatoes until they’re squeaky clean. Dry them completely with paper towels – moisture is the enemy of crispiness.

3

Slice Like a Pro

Grab a sharp knife and cut your sweet potatoes into perfect 1/4-inch thick fry shapes. Keep them as even as possible so they cook consistently.

4

Oil Up the Potatoes

Toss the potato sticks in a large bowl. Drizzle with olive oil and make sure every single piece gets a nice, even coating.

5

Create the Seasoning Mix

Combine your spices in a small bowl. Here’s what you’ll need:

  • 1 tsp salt
  • 1/2 tsp black pepper
  • 1/2 tsp garlic powder
  • 1/4 tsp paprika
  • 1/4 tsp cornstarch
6

Season the Fries

Sprinkle the seasoning mix over your oiled potato sticks. Toss them around until each piece is evenly coated with the spice blend.

7

Arrange on the Baking Sheet

Spread the fries in a single layer on your prepared baking sheet. Make sure they’re not touching – give each fry some personal space.

8

First Bake

Pop the baking sheet in the oven and bake for 15 minutes. The kitchen will start smelling amazing.

9

Flip and Rotate

Use tongs to carefully flip each fry. Rotate the baking sheet to ensure even cooking.

10

Final Bake

Continue baking for another 10-15 minutes. Watch closely – you want golden brown edges that are crisp and delicious.

11

Rest and Serve

Pull the fries out of the oven and let them sit on the baking sheet for 2-3 minutes. This helps them stay extra crispy.

12

Enjoy Immediately

What Smart Kitchen Notes Perfect Sweet Potato Fries

  • Halfway through baking, use tongs to carefully flip and rotate your baking sheet, ensuring each fry gets beautifully golden and crunchy on all sides.

Sweet Potato Fry Seasoning Alternatives

  • Zesty Herb Fries: Swap paprika with dried rosemary, thyme, and oregano for an herbal kick that transforms your sweet potato fries into a Mediterranean-inspired snack.
  • Spicy Cayenne Challenge: Replace garlic powder with cayenne pepper and add extra red pepper flakes to create a fiery version that’ll wake up your taste buds.
  • Gluten-Free Coating: Substitute cornstarch with arrowroot powder or rice flour to make the fries safe for gluten-sensitive friends while keeping the same crispy texture.
  • Parmesan Crunch Upgrade: Sprinkle grated parmesan cheese during the last 5 minutes of baking for a salty, cheesy crust that adds extra crunch to your sweet potato fries.

Classic Ways to Enjoy Sweet Potato Fries

  • Perfect Portion Size: Prepare about 1 sweet potato per person as a hearty side or snack.

Proper Storage For Crispy Oven Baked Sweet Potato Fries

  • Store leftover fries in an airtight container in your refrigerator for up to 3 days, placing a paper towel underneath to absorb moisture and keep them from getting soggy.
  • Reheat refrigerated fries in a preheated 425°F oven for 5-7 minutes to help restore their original crispness, spreading them in a single layer on a baking sheet.
  • Avoid storing your sweet potato fries in plastic containers, as they can trap steam and make the crispy edges turn soft and mushy.
