Ingredients You’ll Need
Here are the ingredients needed to make crispy baked sweet potato fries.
Sweet Potatoes
Choose firm, fresh sweet potatoes without soft spots or significant blemishes. Medium-sized sweet potatoes are usually easier to cut into evenly sized fries.
Olive Oil
A little olive oil helps the fries roast properly and gives them a lightly crisp exterior. You can also use another neutral cooking oil if preferred.
Paprika
Paprika adds a mild, slightly sweet and savory flavor while giving the fries an attractive warm color.
Garlic Powder
Garlic powder adds a savory depth of flavor without overpowering the natural sweetness of the sweet potatoes.
Salt
Salt brings out the flavor of the sweet potatoes and balances their natural sweetness.
Black Pepper
Freshly ground black pepper adds a subtle peppery bite.
Cornstarch
Cornstarch is optional, but it can help create a drier surface that encourages better browning and crisping in the oven.
Ingredients
For a simple batch of baked sweet potato fries, you’ll need:
- 2 large sweet potatoes
- 1½ tablespoons olive oil
- 1 tablespoon cornstarch
- 1 teaspoon paprika
- ½ teaspoon garlic powder
- ½ teaspoon salt
- ¼ teaspoon black pepper
You can adjust the seasoning according to your taste.
How to Make Baked Sweet Potato Fries
1. Preheat the Oven
Preheat your oven to 425°F (220°C).
A properly preheated oven is important because the fries need strong, consistent heat from the beginning. If the oven is still heating when the fries go in, they may take longer to cook and can become softer instead of developing browned edges.
For easier cleanup, you can line a large baking sheet with parchment paper. If using parchment, make sure it is suitable for the temperature of your oven.
2. Wash and Peel the Sweet Potatoes
Wash the sweet potatoes thoroughly under cool running water and scrub away any dirt from the skin.
Peeling is optional. If you like the flavor and texture of the skin, you can leave it on after washing the potatoes well. If you prefer smoother fries, peel them before cutting.
Pat the sweet potatoes completely dry with a clean kitchen towel.
3. Cut the Sweet Potatoes Into Fries
Place each sweet potato on a sturdy cutting board and carefully cut it lengthwise into slabs.
Cut each slab into long strips that are approximately ¼ to ½ inch thick.
Try to keep the fries as similar in size as possible. Fries with similar thickness will cook more evenly, while very thin pieces may cook faster than thicker ones.
4. Soak the Fries
Place the cut sweet potatoes in a large bowl of cold water and let them soak for about 30 minutes.
Soaking can help remove some surface starch and can contribute to better texture.
After soaking, drain the sweet potatoes thoroughly.
5. Dry the Sweet Potatoes Thoroughly
This step is extremely important.
Spread the sweet potato pieces over a clean kitchen towel or paper towels and pat them dry. Try to remove as much surface moisture as possible.
Excess water can create steam in the oven, making it harder for the fries to brown and crisp.
6. Add the Cornstarch
Place the dried sweet potato fries in a clean, dry bowl.
Sprinkle the cornstarch over them and toss gently until the pieces are lightly coated.
Avoid using too much cornstarch. You want a thin coating rather than a thick layer.
7. Add the Oil and Seasonings
Add the olive oil, paprika, garlic powder, salt, and black pepper.
Toss everything together until the fries are evenly coated.
Make sure the seasoning is distributed throughout the fries rather than concentrated in just a few areas.
8. Arrange the Fries on the Baking Sheet
Spread the seasoned sweet potato fries onto a large baking sheet.
Arrange them in one layer, leaving some space between the pieces whenever possible.
Avoid piling the fries on top of one another. When they are crowded, moisture becomes trapped between the pieces, which can prevent proper browning.
If you are making a large batch, use two baking sheets rather than overcrowding one.
9. Bake the Fries
Place the baking sheet in the preheated oven and bake for approximately 15 minutes.
Remove the baking sheet and carefully flip the fries with a spatula or tongs.
Return them to the oven and bake for another 10–15 minutes, or until the fries are tender inside and browned around the edges.
The exact cooking time will depend on the thickness of your fries and your oven.
10. Serve Immediately
Once the fries are finished, remove them from the oven and allow them to cool for a few minutes.
Serve them while they are warm with your favorite dipping sauce.
Sweet potato fries are especially good with creamy sauces, ketchup, barbecue sauce, honey mustard, or a spicy dipping sauce.
How to Get Crispier Baked Sweet Potato Fries
Sweet potatoes naturally contain more moisture than regular potatoes, so getting them crisp in the oven can require a little extra attention.
Cut Them Evenly
Try to keep all the fries approximately the same thickness. If some pieces are very thin while others are thick, they will cook at different rates.
Don’t Skip the Drying Step
After soaking, dry the fries very well. Wet sweet potatoes can steam rather than roast.
Use Cornstarch
A light coating of cornstarch can help create a drier exterior and improve the texture of oven-baked fries.
Don’t Overcrowd the Pan
Give the fries enough room to roast. If they are touching or piled together, they can release moisture and become soft.
Use a Hot Oven
A temperature around 425°F (220°C) provides enough heat to cook and brown the fries effectively.
Flip During Baking
Turning the fries halfway through cooking helps expose both sides to the heat and promotes more even browning.
Serve Soon After Baking
Baked sweet potato fries are generally at their best shortly after they come out of the oven. As they sit, steam and moisture can soften the exterior.
Can You Make Sweet Potato Fries Without Soaking?
Yes. Soaking is optional.
If you’re short on time, you can cut the sweet potatoes, dry them thoroughly, coat them with cornstarch, oil, and seasonings, and bake them directly.
However, soaking can be useful when you’re aiming for a better roasted texture. If you do soak the fries, drying them thoroughly afterward is essential.
Do You Have to Peel Sweet Potatoes?
No. The skin is edible, so peeling is a matter of preference.
Leaving the skin on can give the fries a more rustic appearance and adds texture. If you prefer smooth, uniform fries, peel the sweet potatoes before cutting.
Seasoning Variations
The basic seasoning in this recipe is simple, but you can easily change the flavor.
Spicy Sweet Potato Fries
Add a small amount of cayenne pepper or chili powder to the seasoning mixture for some heat.
Smoky Sweet Potato Fries
Use smoked paprika instead of regular paprika for a deeper, smoky flavor.
Italian-Style Sweet Potato Fries
Add dried Italian herbs such as oregano and basil along with the garlic powder.
Cinnamon Sweet Potato Fries
For a sweeter variation, reduce the savory seasonings and add a small amount of cinnamon. These can be served as a fun snack or side dish.
Garlic Herb Fries
Add dried parsley, oregano, or another favorite herb to the garlic-seasoned fries.
Best Dipping Sauces for Sweet Potato Fries
A good dipping sauce can make baked sweet potato fries even more enjoyable.
Try serving them with:
- Ketchup
- Garlic aioli
- Ranch dressing
- Honey mustard
- Barbecue sauce
- Spicy mayo
- Chipotle-style sauce
- Yogurt-based herb dip
- Maple mustard sauce
You can serve one sauce or offer several options when serving the fries to a group.
What to Serve With Baked Sweet Potato Fries
These fries work well as a side dish for many different meals.
Serve them alongside:
- Hamburgers
- Chicken sandwiches
- Turkey burgers
- Grilled chicken
- Grilled fish
- Chicken wraps
- Pulled chicken sandwiches
- Veggie burgers
- Sandwiches and paninis
- Grilled vegetables
They can also be served as a snack with a dipping sauce.
Storage
If you have leftover sweet potato fries, allow them to cool before placing them in an airtight container.
Store them in the refrigerator and use them within a few days for the best quality.
Keep in mind that refrigerated fries will soften, so they are usually better reheated in the oven or air fryer rather than in the microwave.
How to Reheat Sweet Potato Fries
For the best texture, spread the leftover fries on a baking sheet and reheat them in a hot oven until warmed through.
An air fryer can also work well for reheating because the circulating hot air helps restore some of the exterior texture.
Avoid overcrowding the fries during reheating.
Can You Freeze Baked Sweet Potato Fries?
Yes, sweet potato fries can be frozen, although their texture may change slightly after freezing and reheating.
For the best results, arrange the cooked fries in a single layer and freeze them before transferring them to a freezer-safe container or bag.
When you’re ready to eat them, reheat them directly from frozen in a hot oven or air fryer until heated through.
Common Mistakes to Avoid
Cutting the Fries Too Thick
Very thick fries can take longer to cook and may remain soft in the center while the outside browns.
Leaving Too Much Moisture on the Fries
Water on the surface can create steam and interfere with browning.
Using Too Much Oil
Adding more oil does not necessarily make the fries crispier. Too much can make them greasy and heavy.
Overcrowding the Baking Sheet
This is one of the most common reasons oven-baked fries turn out soft.
Forgetting to Flip Them
Flipping halfway through cooking helps the fries brown more evenly.
Expecting Them to Be Exactly Like Deep-Fried Fries
Oven-baked sweet potato fries have their own texture and character. They can become nicely browned and crisp around the edges, but they may not have exactly the same texture as deep-fried fries.
Frequently Asked Questions
Why are my baked sweet potato fries not crispy?
The most common causes are excess moisture, overcrowding the baking sheet, fries that are cut too thick, or an oven that isn’t hot enough. Dry the fries thoroughly, use a light cornstarch coating, and leave enough space between the pieces.
Should I soak sweet potatoes before baking fries?
Soaking is optional, but it can help with texture. If you soak them, make sure you dry them very thoroughly before adding the cornstarch, oil, and seasonings.
What temperature is best for baking sweet potato fries?
425°F (220°C) is a good temperature for roasting sweet potato fries. Cooking time will vary depending on the thickness of the fries and your oven.
Can I make these fries without cornstarch?
Yes. Cornstarch is optional. The fries can still be delicious without it, although the texture may be somewhat different.
Why do my sweet potato fries become soft after baking?
Sweet potatoes naturally contain considerable moisture. Crowding the pan can trap that moisture and cause the fries to steam. Allow plenty of space between the fries and serve them soon after baking.
Can I leave the skin on?
Yes. Wash and scrub the sweet potatoes thoroughly before cutting them if you plan to leave the skin on.
