Ingredients Overview

Crispy sweet potato fries require just a few pantry staples and one or two secret weapons for crunch.

Sweet potatoes – Look for firm, evenly shaped sweet potatoes. Their natural sweetness and starch content are perfect for roasting. Leave the skin on for extra texture and fiber, or peel for a cleaner look.

Cornstarch – This is the secret to crispiness. It creates a thin coating that browns beautifully in the oven. You can also use arrowroot powder or tapioca starch.

Olive oil – Helps the fries brown and crisp up. Use just enough to coat—too much oil can make them soggy.

Salt – Essential for seasoning. Add before and after baking for maximum flavor.

Paprika & garlic powder – Optional but recommended. These spices add savory depth without overpowering the sweet potato flavor.

Optional add-ins:

• Smoked paprika for a smoky twist
• Chili powder for heat
• Fresh chopped parsley or cilantro for garnish

Substitutions:

• Use avocado oil for a higher smoke point.
• Try Japanese sweet potatoes (white flesh) for a different texture.
• Skip spices and use cinnamon and sugar for a sweet version.

Step-by-Step Instructions

1. Preheat the oven:
Set your oven to 425°F (220°C). Line two large baking sheets with parchment paper for easy cleanup and even browning.

2. Cut the sweet potatoes:
Wash and dry 2 large sweet potatoes. Cut into even matchsticks, about ¼ inch thick. The thinner and more uniform, the crispier they’ll get.

3. Soak the fries (optional but helpful):
Place the cut fries in a bowl of cold water for 30 minutes. This helps remove excess starch and leads to crispier fries. Drain and pat completely dry with a clean towel.

4. Coat with cornstarch:
In a large bowl, toss fries with 1½ tablespoons of cornstarch until evenly coated.

5. Add oil and seasonings:
Drizzle with 1½ tablespoons olive oil, 1 tsp salt, ½ tsp paprika, and ½ tsp garlic powder. Toss well to coat evenly.

6. Arrange on baking sheets:
Spread fries in a single layer on the prepared baking sheets, leaving space between each fry. Don’t overcrowd—they need room to crisp.

7. Bake:
Bake for 15 minutes. Flip each fry with tongs or a spatula, rotate the pans, and bake for another 10–15 minutes, or until golden and crisp on the edges.

8. Rest and season:
Remove from the oven and let them sit for 5 minutes—this helps the exterior firm up. Sprinkle with a little extra salt if needed and serve immediately.

Common mistakes to avoid:

• Don’t skip drying the fries—moisture leads to steaming.
• Avoid too much oil—it can make them limp.
• Don’t overcrowd the pan—use two sheets if necessary.

Tips, Variations & Substitutions

Tips:

• Cut your fries evenly for uniform cooking.

• Sprinkle with Parmesan cheese and chopped rosemary after baking.
• Add a squeeze of lime and a pinch of chili powder for a zesty version.

Substitutions:

• Use arrowroot starch instead of cornstarch if preferred.
• Try Yukon gold potatoes for classic-style oven fries.
• Use garlic-infused oil for a bolder flavor without burning garlic in the oven.

Nutritional & Health Notes

Sweet potatoes are rich in fiber, vitamin A, and antioxidants. Baking instead of frying cuts down on fat while keeping the flavor and texture you crave.

Using olive oil and a moderate amount of salt keeps the dish balanced and heart-healthy. This recipe is naturally gluten-free, dairy-free, and vegan, making it friendly for a variety of dietary preferences.

To keep sodium lower, season lightly and offer dipping sauces on the side for controlled flavor boosting.

FAQs

1. Why aren’t my fries getting crispy?
Common reasons include too much oil, overcrowding the pan, or not drying the sweet potatoes after soaking. Use parchment paper and space them out well.

2. Can I skip the cornstarch?
Yes, but they won’t be as crisp. Cornstarch creates that light, crispy coating. Arrowroot or tapioca starch can be used as alternatives.

3. Do I have to peel the sweet potatoes?
No. The skin adds texture and nutrients. Just scrub them well before cutting.

4. How do I reheat leftovers?
Reheat in a 400°F oven or air fryer for 5–10 minutes to bring back crispness. Avoid the microwave—it makes them soggy.

5. Can I use an air fryer instead?
Yes! Cook at 375°F for 12–15 minutes, shaking halfway through. Avoid overcrowding the basket for best results.

6. Are these fries healthy?
Yes. They’re baked with a small amount of oil and use whole food ingredients. They offer fiber, complex carbs, and beta carotene.

7. What dips go best with these fries?
Garlic aioli, chipotle mayo, yogurt dill dip, honey mustard, and classic ketchup all pair beautifully. Choose your favorite or try something new.
