Key ingredients and tips
- Olive oil: I use a good splash to help the spices stick and get that golden finish. Skip it if you’re avoiding fats, but expect less crispness.
- Sweet potatoes: I choose firm, vibrant ones with no blemishes. The rich orange hue means they’re packed with flavor and natural sweetness that caramelizes beautifully.
- Salt: I like a coarse sea salt for that satisfying crunch with every bite. Adjust based on your preference for saltiness or try smoked salt for depth.
- Paprika: I add smoked paprika for a subtle smoky kick that makes the fries pop. If you prefer milder, use sweet paprika or skip it altogether.
- Black pepper: Freshly cracked, it gives a sharp contrast to the sweetness. Grind it just before baking to keep that bright, pungent punch.
- Optional spices: I sometimes throw in a pinch of cumin or cayenne for extra warmth or heat. Less is more—start small and build up.
- Cornstarch (or arrowroot): I toss the cut fries in a light dusting to boost crispiness. Skip if you prefer a softer fry, but your oven-baked version won’t be as crunchy.
Spotlight on key ingredients
Sweet potatoes:

Olive oil:
- I prefer a good-quality extra virgin for flavor and browning. It helps the fries crisp up without feeling greasy or heavy.

Step-by-step guide to baked sweet potato fries
- Preheat your oven to 220°C (430°F). Line a baking sheet with parchment paper or a silicone mat to prevent sticking.
- Wash and peel the sweet potatoes. Cut into uniform sticks about 1/4 to 1/3 inch thick to ensure even cooking.
- In a large bowl, toss the cut sweet potatoes with 1-2 tablespoons of olive oil, making sure each piece is coated well.
- Add 1 teaspoon of smoked paprika, 1/2 teaspoon of sea salt, and a pinch of black pepper. Toss again to distribute the spices evenly.
- If using, sprinkle a light dusting of cornstarch or arrowroot powder over the fries. Toss gently for extra crispness.
- Arrange the fries in a single layer on the prepared baking sheet, leaving space between each piece for air circulation.
- Bake for 20 minutes, then flip the fries using tongs or a spatula. Return to the oven and bake for an additional 10-15 minutes.
- Watch for golden-brown edges and a slight crackle when you shake the sheet. The fries should be crispy around the edges and tender inside.
- Once done, remove from oven and let rest for 2-3 minutes. This helps firm up the crust.
- Serve immediately with your favorite dipping sauce or a sprinkle of finishing salt. Enjoy the warm, smoky aroma and crispy bite.
Let the fries rest for 2-3 minutes out of the oven to set the crust. Serve immediately on a warm plate or in a bowl. Optional: sprinkle with flaky sea salt or a squeeze of lemon for brightness.

Pro tips for perfect baked sweet potato fries

Common mistakes and how to fix them
- FORGOT to preheat the oven → Ensure oven reaches 220°C (430°F) before baking.
- DUMPED fries on pan without space → Arrange in a single layer for maximum crispness.
- OVER-TORCHED edges → Remove fries once edges are golden and slightly darker, not burnt.
- SKIPPED flipping during baking → Flip at 20-minute mark for even browning.
Quick fixes and pantry swaps
- When fries are limp, splash a little vinegar on them before reheating for a crispy revive.
- If fries burn quickly, shield edges with foil midway through baking.
- Splash some lemon juice on raw fries to brighten flavor and prevent browning.
- Dumped fries too close? Reshape on the tray for even crisping during bake.
- When lacking cornstarch, pantry swap with rice flour for a lighter crunch.
Prep, store, and reheat tips
- You can cut the sweet potatoes into fries a few hours ahead. Keep them in a sealed container in the fridge—just toss with a little lemon juice to prevent browning and keep that fresh look.
- Store baked fries in an airtight container in the fridge for up to 2 days. Reheat in a hot oven (around 200°C/390°F) until crispy again—watch for that crackle and golden edges.
- Refrigerated fries will lose some crispness over time. A quick blast in the oven or air fryer restores their crunch — smell that smoky, roasted aroma again.
- Avoid freezing cooked fries; they tend to get soggy when reheated. Freshly baked is best, but if you must freeze, do so unbaked, then bake from frozen for best results.
- To reheat raw cut sweet potatoes, keep them covered in the fridge for up to 24 hours. Don’t soak them; just pat dry before tossing with oil and spices for baking later.
