Crispy oven baked sweet potato fries are my go to for healthy snacking and crowd pleasing sides when I want something both crunchy and satisfying. These fries skip the heavy oil of deep frying without sacrificing taste or texture thanks to a smart baking method and simple seasonings.
When I first made these for a family movie night everyone kept reaching for more and there were no leftovers in sight.
Ingredients
- Sweet potatoes: pick firm and vibrant sweet potatoes for best flavor and color I like to keep the skin on for extra fiber but peeling makes them look more like classic fries
- Olive oil: helps the fries get crispy without excess grease choose a robust extra virgin if you can
- Garlic powder: brings a tasty savory edge use a fresh batch for fullest flavor
- Paprika: adds a gentle smoky warmth smoked paprika creates a beautifully rich color and deeper flavor
- Salt: draws out moisture and seasons the fries sea salt has a clean pure flavor
- Black pepper: gives a mild heat try freshly ground for a fragrant kick
- Cornstarch: optional but highly recommended for shattering crisp results it helps wick away any extra moisture during baking
Step-by-Step Instructions
- Preheat the Oven:
- Get your oven hot at 425 F Place a baking sheet inside while the oven heats so the fries sizzle as soon as they hit the pan This lets the bottoms crisp up faster
- Cut and Prep the Sweet Potatoes:
- Slice sweet potatoes into one quarter inch fries Try to keep each piece a similar size for even roasting If you want classic fry shape cut the sweet potato lengthwise first then into sticks
- Soak and Dry:
- Drop your cut fries into a large bowl of cold water for thirty minutes This step pulls away extra starch so you get fries that actually crisp up not get soggy Drain really well and lay out the fries between two clean towels then pat dry until no water droplets remain
- Season Thoroughly:
- Toss your fries in a big mixing bowl with olive oil garlic powder paprika salt and black pepper For extra crunch add a tablespoon of cornstarch and toss everything until every fry is well coated and glossy
- Bake for Maximum Crunch:
- Carefully pull your hot baking sheet from the oven Spread your fries out into one even layer no overlapping or touching for perfect airflow Bake for twenty five to thirty minutes flipping fries halfway through roasting so all sides brown up beautifully
- Cool and Serve:
- Once the edges look golden and crispy remove the fries and let cool for at least five minutes before serving They firm up even more as they cool

The cornstarch technique was a revelation to me Now I never skip this step because it gives that satisfying bite just like diner style fries My kids always ask whose batch is crispiest and it turns into a fun crispy fry contest at our table
Storage Tips
Cool completely before storing in an airtight container in the fridge They keep well for up to four days To reheat spread on a baking sheet and warm in a hot oven to revive the outer crispiness Avoid microwaving which can make fries soggy
Ingredient Substitutions
You can swap olive oil for avocado oil or grapeseed oil if needed Both options handle high heat well Cajun seasoning or chili powder also make great alternatives to paprika for a spicy kick If you do not have cornstarch rice flour can be a backup for crisping
Serving Suggestions
Pair these fries with your favorite dipping sauces My family loves serving them with spicy mayo or classic ketchup For a party platter pile up with black bean burgers or grilled chicken on the side They even make a tasty topping for loaded nacho style trays

Set oven to 220°C and insert a baking sheet to heat while preparing sweet potatoes.
Peel sweet potatoes if desired. Slice into uniform fries approximately 0.6 cm thick to promote even cooking.
Immerse sliced sweet potatoes in a bowl of cold water for 30 minutes to draw out excess starch, aiding crispiness.
Drain fries and thoroughly pat dry with paper towel. In a large bowl, toss with olive oil, garlic powder, paprika, salt, and black pepper. If desired, add cornstarch and toss to evenly coat.
Carefully remove the heated baking sheet from the oven. Arrange sweet potato fries in a single layer, ensuring they are not overcrowded. Bake for 25–30 minutes, flipping fries midway through, until golden and crisp.
Remove fries from the oven once crisp and golden brown. Allow to cool briefly before serving.
