What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and that signature crispy texture—no deep fryer required. If you love recipes with pantry staples and easy swaps, you’ll appreciate how flexible these crispy oven baked sweet potato fries really are.

• Sweet Potatoes (2 large, about 1.5 lbs / 700g) – Peeled or unpeeled, cut into 1/4-inch (0.6cm) sticks. Look for ones that are firm and smooth.
• Cornstarch (2 tablespoons / 16g) – This is my secret weapon for crispiness. Potato starch also works.
• Olive Oil (2 tablespoons / 30ml) – I prefer extra-virgin olive oil for flavor, but avocado oil or grapeseed oil work too.
• Sea Salt (1 teaspoon / 6g) – Fine or flaky, to taste. I love Maldon for a fancy finish.
• Black Pepper (1/2 teaspoon / 1g) – Freshly ground gives the best flavor.
• Smoked Paprika (1 teaspoon / 2g, optional) – Adds a subtle smokiness. Regular paprika or chili powder are great swaps.
• Garlic Powder (1/2 teaspoon / 1g, optional) – For a savory boost. Onion powder is a tasty alternative.

Optional for Serving or Dipping:

• Fresh chopped parsley or cilantro
• Crumbled feta or cotija cheese
• Homemade aioli, Greek yogurt dip, or classic ketchup

Ingredient Tips:

• Choose smaller, skinnier sweet potatoes for fries that cook evenly and crisp up better.
• If you want to make these gluten-free, double-check your cornstarch label (some brands process with wheat).
• No cornstarch? Arrowroot powder or potato starch also work, but don’t skip this step—it’s key!
• For a lower-oil version, you can cut the oil back by half. The fries won’t be quite as crisp, but they’re still delicious.

See? Nothing fancy or hard to find here. Most of these are pantry staples, and the seasonings are easily adjustable to your taste. Trust me, once you nail this base recipe, you’ll start getting creative with your own flavor combos.

Equipment Needed

• Large Baking Sheets: At least two, so you can spread the fries out. I like rimmed aluminum sheets for even browning.
• Parchment Paper: Prevents sticking and makes cleanup a breeze. Silicone baking mats are a great reusable option.
• Sharp Knife: For cutting the sweet potatoes into even sticks. If you have a fry cutter, even better, but not necessary.
• Large Mixing Bowl: For tossing the fries in oil, cornstarch, and seasonings.
• Tongs or Spatula: For flipping fries halfway through baking.
• Measuring Spoons: For the oil and spices (eyeballing works, but I’m a fan of consistency).

If you don’t have parchment paper, lightly oil your baking sheets to prevent sticking. I’ve tried both ways, and parchment wins for the best, even crispiness. My trusty chef’s knife has seen more sweet potatoes than I can count, but a mandoline slicer can also help if you want perfectly even fries (just watch your fingers!). For budget-friendly options, basic stainless steel sheets and a sharp kitchen knife are all you really need. Just steer clear of dark nonstick pans—they can burn the fries’ bottoms before the tops crisp up.

Preparation Method

1. Preheat your oven: Heat to 425°F (220°C). Place two racks near the center. A hot oven is key for crispy oven baked sweet potato fries.
   
   Tip: Let your oven preheat for a full 20 minutes for the most even heat!
2. Prep the sweet potatoes: Wash and dry your sweet potatoes. Peel them if you like (I usually leave the skins on for extra fiber and rustic vibes). Cut into 1/4-inch (0.6cm) thick sticks. Try to keep them as uniform as possible.
   
   Note: If your fries are too thick, they’ll be soft. Too thin, and they can burn. Aim for that “classic fry” size.
3. Soak (optional, but recommended): Place cut fries in a bowl of cold water for 30 minutes, or up to 2 hours. This draws out excess starch for the crispiest results.
   
   Shortcut: If you’re short on time, skip the soak, but your fries may be a touch softer.
4. Dry thoroughly: Drain the fries and pat dry with a clean towel. They should be as dry as possible—this is super important! Wet fries = steamed, not crispy.
5. Toss with cornstarch: Add the fries to a large bowl. Sprinkle with cornstarch and toss until each fry has a light, even dusting.
   
   Troubleshooting: Too much cornstarch makes fries dusty; too little, and they won’t crisp. Stick to 2 tablespoons for 2 large potatoes.
6. Add oil and seasonings: Drizzle in olive oil and toss to coat. Add salt, pepper, paprika, and garlic powder. Toss again until fries are evenly coated.
   
   Tip: I like to use my hands (clean, of course) for the most even coating.
7. Arrange on baking sheets: Spread fries in a single layer with space between them. Don’t overcrowd—use two sheets if needed. If they touch, they’ll steam instead of crisp.
8. Bake: Place trays in the oven and bake for 15 minutes.
9. Flip: Remove trays and flip each fry using tongs or a spatula. Rotate the trays between racks for even cooking.
   
   Personal tip: Don’t rush the flip! Gently loosen any fries that want to stick.
10. Bake again: Return to the oven and bake 12-18 more minutes, until fries are deep golden and crisp at the edges.
    
    Sensory cue: They should smell toasty and sound crispy when you tap them with the spatula.
11. Finish and serve: Sprinkle with extra salt or chopped herbs if desired. Serve hot, right off the tray. (No shame in eating them with your fingers!)

Extra efficiency tip: While the fries bake, whip up your favorite dip or prep the rest of your meal. The timing is perfect for multitasking!

Cooking Tips & Techniques

After a lot of trial and error (and a few burnt batches!), I’ve picked up some tricks for the crispiest oven baked sweet potato fries every single time:

• Don’t skip the soak: It pulls out starch and helps the fries brown and crisp instead of going limp. Even a quick 20-minute soak makes a difference.
• Dry, dry, dry: I can’t stress this enough. Any moisture is the enemy of crunch—pat the fries with a towel until there’s no visible water.
• Use cornstarch sparingly: Too much, and you’ll get powdery fries. Too little, and they’ll be soft. Measure for best results.
• High heat is your friend: 425°F (220°C) gives you the perfect balance of caramelized outsides and tender insides. Lower temps won’t crisp them up.
• Don’t crowd the pan: Spread the fries in a single layer. If they’re piled up or touching, they’ll steam—not crisp.
• Flip halfway: It’s tempting to skip, but flipping ensures even browning and the ultimate crunch factor.
• Rotate baking sheets: Oven hot spots are real! Swapping racks and rotating pans halfway through keeps things even.

I once tried baking a double batch on one tray (rookie mistake). Result? Soggy, sad fries. Lesson learned: use two sheets, even if you have to bake in batches. And if you want extra-caramelized edges, let the fries sit on the hot tray for a few minutes after baking—just don’t let them go cold. Consistency comes with practice, but these tips will get you pretty darn close to fry perfection, every time!

Variations & Adaptations

One of the best things about crispy oven baked sweet potato fries is how easy they are to customize. Here are some favorite twists (and a few I’ve picked up from readers!):

• Spicy Fries: Add 1/2 teaspoon cayenne pepper or chipotle powder with the seasonings for a fiery kick. Serve with cooling ranch or yogurt dip.
• Herb & Garlic Fries: Toss with minced fresh rosemary, thyme, or parsley after baking. For more punch, add 1 teaspoon Italian seasoning before baking.
• Parmesan Crusted: Sprinkle 2 tablespoons finely grated parmesan cheese over hot fries right out of the oven. The cheese melts and adds a salty crunch.
• Gluten-Free/Vegan: The base recipe is naturally gluten-free and vegan! Just make sure your cornstarch and seasonings are certified if you’re super sensitive.
• Air Fryer Adaptation: Prep fries as directed, then cook in a single layer in your air fryer at 400°F (200°C) for about 12-15 minutes, shaking halfway.
• Low-Sodium: Use half the salt and amp up fresh herbs or spices instead.
• My Favorite Twist: I sometimes toss the baked fries with a little fresh lime zest and chili powder for a sweet-tart, zippy finish. So good with a smoky chipotle dip!

If you try a new take, let me know in the comments! There’s no wrong way to enjoy these fries—just endless delicious possibilities.

Serving & Storage Suggestions

These crispy oven baked sweet potato fries are best enjoyed fresh out of the oven, piping hot and perfectly crisp. I love serving them in a parchment-lined basket or piled high on a rustic wooden board—makes them feel a little extra special, even for a weeknight dinner.

• Serving ideas: Pair them with classic burgers, grilled chicken, veggie wraps, or just enjoy as a snack with your favorite dip (think spicy mayo, herbed yogurt, or simple ketchup).
• Presentation tip: Sprinkle with fresh herbs or a dusting of smoked paprika for a pop of color. If you’re serving to guests, a trio of dips always impresses!
• Storage: Store cooled fries in an airtight container in the fridge for up to 3 days. They soften over time but are still super tasty.
• Reheating: Spread leftovers on a baking sheet and bake at 400°F (200°C) for 8-10 minutes, or until crisp again. Air fryers also work well for re-crisping.
• Freezing: These fries don’t freeze as well as classic potato fries, but if you must, freeze in a single layer and reheat straight from frozen. Expect a softer texture, but still good flavor.
• Flavor tip: The sweet and savory flavors deepen after a day, so they’re great for meal prep or make-ahead lunches (just give them a quick reheat for best texture).

FAQs

How do I keep my sweet potato fries crispy after baking?

Spread them out in a single layer and avoid covering them while hot. For leftovers, reheat in the oven or air fryer to regain crunch.

Can I use regular potatoes instead of sweet potatoes?

Absolutely! The same technique works for russet or Yukon gold potatoes—just slice, soak, and bake as directed.

Why do my fries get soggy?

Most likely, they’re crowded on the pan or not dried well after soaking. Make sure there’s space between each fry and they’re fully dry before baking.

Is cornstarch necessary for this recipe?

It really helps with crispiness, but you can swap in potato starch or arrowroot powder if you don’t have cornstarch on hand.

Can I make these fries ahead of time?

You can prep and cut the fries in advance (store them in water in the fridge), but for best texture, bake them fresh before serving.
