- 2 large sweet potatoes – Peeled (or scrubbed clean if you prefer skin-on).
- 1 ½ tablespoons cornstarch – The key to crispiness.
- 2 tablespoons olive oil – Or avocado oil for high-heat roasting.
- ½ teaspoon garlic powder – Adds depth of flavor.
- ½ teaspoon smoked paprika – For a hint of smokiness.
- ½ teaspoon salt – More to taste.
- Optional: pinch of cayenne pepper – For a subtle kick.
Tools You’ll Need
Having the right tools makes the process smoother:
- Large sharp knife or mandoline slicer
- Cutting board
- Large mixing bowl
- Parchment paper or silicone baking mats
- Two baking sheets
- Tongs or spatula for flipping
Step-by-Step Instructions
Follow these steps for perfect results every time:
1. Preheat & Prep
Set your oven to 425°F (220°C). Line two baking sheets with parchment paper.
2. Slice Sweet Potatoes
Cut the potatoes into even matchsticks, about ¼-inch thick. Uniformity ensures even baking.
3. Optional Soak
Soak fries in cold water for 30 minutes to remove excess starch. Drain and pat completely dry with a clean towel.
4. Toss in Cornstarch
In a mixing bowl, coat the fries with cornstarch. This creates the crunchy exterior.
5. Season
Add olive oil, garlic powder, paprika, salt, and any optional spices. Toss until evenly coated.
6. Arrange & Bake
Spread fries in a single layer on the baking sheets. Don’t overcrowd! Bake for 15 minutes, flip, then bake another 10–15 minutes until golden and crispy.
7. Rest & Serve
Let fries cool for 5 minutes before serving—they’ll crisp up even more as they rest.
Flavor Variations
Once you master the basic recipe, get creative with seasonings:
- Spicy Kick – Add cayenne, chili powder, or chipotle.
- Sweet Dessert Fries – Toss with cinnamon and sugar instead of savory spices.
- Herby Delight – Sprinkle rosemary, thyme, or Italian seasoning.
- Cheesy Twist – Dust with grated Parmesan right after baking.
- Zesty Lemon Pepper – Add lemon zest and cracked black pepper for brightness.
Best Dipping Sauces
Sweet potato fries pair beautifully with all kinds of dips. Try:
- Garlic aioli
- Chipotle mayo
- Spicy ketchup
- Ranch dressing
- Honey mustard
- Avocado crema
- Tahini sauce
- Maple-dijon blend
Expert Tips for Extra Crispy Results
- Don’t skip cornstarch—it’s the secret weapon.
- Make sure fries are completely dry before coating.
- Spread fries apart so they roast, not steam.
- Flip halfway and rotate baking sheets for even cooking.
- Let them cool briefly after baking for maximum crispiness.
Serving Ideas
Crispy oven-baked sweet potato fries aren’t just a side dish—they can be the star of the meal. Here are pairing ideas:
- With burgers (classic or plant-based)
- Alongside grilled chicken or steak
- As a side to pasta bowls

Storage and Reheating
- Fridge – Store in an airtight container for up to 3 days.
