Before You Start: Tips & Ingredient Notes
- Pick the right potatoes. Look for sweet potatoes that are firm and smooth, without any soft spots or sprouts. Their shape matters more than you think—long, uniformly-shaped potatoes are easier to cut into even fry shapes.
- Why cornstarch? It might seem odd, but this is the game-changer. A light dusting of cornstarch absorbs excess surface moisture and helps create a delightfully crispy exterior without making the fries taste powdery or weird.
- The soaking step is non-negotiable. Soaking the cut fries in cold water for at least 30 minutes pulls out the excess starch, which is the primary culprit for steaming and sogginess in the oven. It’s the single most important step for crispiness.
- Don’t crowd the pan. If you pile all the fries onto one baking sheet, they’ll steam each other instead of roasting. Using two sheets or working in batches is far better than ending up with a soggy mess. A little patience here pays off.
How to Make Baked Sweet Potato Fries
Step 1: First, scrub your sweet potatoes clean under running water—you can leave the skin on for extra fiber and texture, or peel them if you prefer. Pat them completely dry with a kitchen towel. Using a sharp knife, slice the potatoes into fry-shaped batons, aiming for about ¼ to ½-inch thickness. The key is to get them as uniform as possible so they cook at the same rate. If some are thin and some are thick, you’ll have a mix of burnt and undercooked fries.
Step 2: Now, for the secret soak. Place all your cut fries into a large bowl and cover them with cold water. Let them sit for at least 30 minutes, though an hour is even better if you have the time. You’ll actually see the water get cloudy—that’s the excess starch leaving the potatoes. After soaking, drain the fries and then dry them thoroughly. I mean, really thoroughly. Use a clean kitchen towel or paper towels and pat them until they are completely dry to the touch. Any residual water will create steam and prevent browning.
Step 3: Preheat your oven to a nice and hot 425°F (220°C). This high heat is crucial for achieving that crispy exterior. While it’s heating, place your thoroughly dried fries back into the large, dry bowl. Drizzle with the oil and toss to coat evenly. You want every surface to have a fine sheen. Then, sprinkle the cornstarch over the top and toss again until the fries are lightly and evenly dusted. It will look almost invisible, but trust the process.
Step 4: Now, add your seasonings. Sprinkle the garlic powder, smoked paprika, salt, and black pepper over the fries. Toss everything one last time until the spices are distributed evenly. The cornstarch will have helped the oil cling to the fries, which in turn helps the spices stick. You should have beautifully coated, non-sticky fries ready for the oven.
Step 5: Line your baking sheet with parchment paper or a silicone mat—this prevents sticking and makes cleanup a breeze. Arrange the fries in a single layer, making sure they aren’t touching each other. If they’re crowded, they’ll steam. It’s better to use two baking sheets than to overcrowd one. Pop them into the preheated oven and set your timer for 15 minutes.
Step 6: After 15 minutes, it’s time to flip. The fries should be starting to brown on the bottom. Carefully flip them over using a spatula or tongs. This ensures even cooking and browning on all sides. You’ll notice some might be cooking faster than others—that’s okay, just rotate the pan if needed. Return them to the oven for another 10 to 15 minutes.
Step 7: Keep a close eye on them during the final few minutes. They’re done when the edges are crispy and caramelized, and the centers are tender. Some smaller pieces might be ready sooner, so you can pull those out if necessary. Let the fries cool on the baking sheet for about 5 minutes—they’ll crisp up a bit more as they sit. Give them a final sprinkle of salt while they’re still hot, and they’re ready to serve immediately!
Storage & Freshness Guide
- Fridge: Store cooled leftovers in an airtight container for up to 3 days.
- Freezer: Freeze unbaked, coated fries on a parchment-lined sheet, then transfer to a freezer bag for up to 3 months. Bake from frozen, adding a few extra minutes.
- Reviving: Reheat in a 400°F (200°C) oven or air fryer for 5-10 minutes to restore crispiness.
