Crispy Oven Baked Sweet Potatoes

Category: Simple Sides to Complete Any Meal

These crispy oven baked sweet potatoes feature a golden, crunchy exterior and a tender inside, all achieved without the use of a fryer. Sliced sweet potatoes are tossed with olive oil, garlic powder, paprika, salt, and pepper, then baked at high heat, ensuring maximum crispiness. For even more crunch, a light dusting of cornstarch can be added before baking. Soaking the potatoes in cold water before seasoning draws out excess starch, making the finished fries extra crisp. Enjoy them hot from the oven for a savory side that’s both healthy and deeply satisfying.

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.

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

Soak the cut sweet potatoes in cold water to remove excess starch, then thoroughly dry before tossing with oil and seasoning. Baking on a preheated sheet and using cornstarch boosts crispiness.

→ Can I leave the skin on the sweet potatoes?

Yes, the skin is edible and adds texture. Just scrub the potatoes well if you choose not to peel them.

Paprika, garlic powder, black pepper, and a touch of smoked paprika add depth. You can experiment with spices like chili or cinnamon for variety.
