Ingredients
Main Components
- 2 medium sweet potatoes, peeled (optional) and cut into fries
- 2 tablespoons olive oil
- 1 teaspoon garlic powder
- 1 teaspoon paprika (smoked paprika is optional for extra flavor)
- 1 teaspoon salt
- 1/2 teaspoon black pepper
Optional
- 1 tablespoon cornstarch (for extra crispiness)
Instructions
Preheat and prepare
Preheat your oven to 425°F (220°C). This high temperature is crucial for achieving crispy fries. Place a baking sheet inside the oven while it preheats—this creates an immediate sizzle when the fries hit the hot surface, jumpstarting the crisping process.
Cut the sweet potatoes
Peel the sweet potatoes if desired (leaving the skin on adds extra nutrients and fiber). Cut them into fries about 1/4 inch thick, keeping them as uniform as possible. Consistent sizing ensures all the fries cook at the same rate, preventing some from burning while others remain undercooked.
Soak for crispiness
Place the cut sweet potato fries in a large bowl filled with cold water and let them soak for 30 minutes. This crucial step removes excess starch from the surface of the potatoes, which is the secret to achieving that crispy exterior. Don’t skip this step—it makes a noticeable difference in texture!
Season the fries
After soaking, drain the fries completely and pat them thoroughly dry with paper towels or a clean kitchen towel. Any remaining moisture will create steam during baking, preventing crispiness. Transfer the dried fries to a large bowl and toss with olive oil, garlic powder, paprika, salt, and black pepper until evenly coated. If using cornstarch for extra crispiness, sprinkle it over the fries now and toss everything together until well distributed.
Bake to perfection
Carefully remove the hot baking sheet from the oven using oven mitts. Spread the seasoned fries in a single layer on the sheet, making sure they don’t overlap or touch—overcrowding creates steam and leads to soggy fries. Bake for 25-30 minutes, flipping the fries halfway through the cooking time for even browning. The fries are done when they’re golden brown and crispy on the edges.
Cool and serve
Once the fries reach your desired level of crispiness, remove them from the oven and let them cool for 2-3 minutes before serving. This brief resting period allows them to firm up slightly and makes them easier to handle. Serve immediately while they’re at their crispiest!
Pro Tips
- The cornstarch trick: For maximum crispiness, toss the fries with 1 tablespoon of cornstarch after seasoning. It creates a light coating that absorbs moisture and delivers restaurant-quality crunch.
- Use a mandoline or french fry cutter for perfectly uniform fries that cook evenly.
- Don’t overcrowd the pan—use two baking sheets if necessary to give fries proper spacing.
- Pat the fries completely dry after soaking; moisture is the enemy of crispiness.
- For extra smoky flavor, use smoked paprika instead of regular paprika.
- Flip the fries gently with a spatula to avoid breaking the crispy coating.
- If some fries cook faster than others, remove the done ones and return the rest to the oven.
Ingredient Substitutions
- Sweet potatoes: Try regular russet potatoes, purple potatoes, or butternut squash for variety.
- Olive oil: Avocado oil or melted coconut oil work beautifully and have high smoke points.
- Garlic powder: Fresh minced garlic or garlic salt (reduce added salt accordingly).
- Paprika: Cayenne pepper for heat, or try cumin for an earthy twist.
- Cornstarch: Arrowroot powder or potato starch provide similar crisping effects.
- Black pepper: White pepper for a milder flavor or crushed red pepper flakes for spice.
Serving Suggestions
These crispy sweet potato fries pair perfectly with:
- Classic ketchup, aioli, or ranch dressing for dipping
- Chipotle mayo, sriracha mayo, or garlic aioli for elevated flavor
- Burgers, sandwiches, or pulled pork as a side dish
- Grilled chicken, fish tacos, or BBQ ribs
- A fresh green salad for a lighter meal
- Honey mustard or maple tahini sauce for sweet and savory contrast
Storage & Reheating
Sweet potato fries are always best fresh from the oven, but you can store leftovers with these tips:
Refrigerator: Store cooled fries in an airtight container for up to 3 days. Note that they will lose some crispiness.
Reheating: For best results, reheat in a 400°F oven or air fryer for 5-8 minutes until crispy again. Avoid the microwave, which makes them soggy.
Freezing: Freeze uncooked seasoned fries in a single layer on a baking sheet, then transfer to a freezer bag for up to 3 months. Bake from frozen, adding 5-10 extra minutes to cooking time.
Make-ahead: Cut and soak the fries up to 24 hours in advance. Store in water in the refrigerator, then drain, dry, and season just before baking.
Meal prep: Prepare multiple batches and freeze for quick weeknight sides—no need to thaw before baking.
Frequently Asked Questions
Q: Do I need to peel the sweet potatoes?
Peeling is optional. Leaving the skin on adds extra fiber, nutrients, and a rustic appearance. Just scrub them well if keeping the skin.
Q: Why do I need to soak the fries?
Soaking removes excess surface starch, which helps the fries crisp up instead of becoming gummy. This 30-minute step is the secret to restaurant-quality results.
Q: Can I make these in an air fryer?
Absolutely! Air fry at 400°F for 15-20 minutes, shaking the basket every 5 minutes for even cooking. They’ll be even crispier than oven-baked.
Q: My fries aren’t crispy. What went wrong?
Common issues include: not drying the fries thoroughly after soaking, overcrowding the pan, or using too much oil. Make sure fries are spread in a single layer with space between them.
Q: Can I double this recipe?
Yes, but use two separate baking sheets. Overcrowding prevents proper air circulation and results in steamed, soggy fries instead of crispy ones.
Q: What other seasonings work well?
Try cajun seasoning, taco seasoning, Italian herbs, curry powder, cinnamon and sugar for a sweet version, or parmesan and rosemary.
