Spiced Sweet Potato Wedges

Why This Spiced Sweet Potato Wedges Works

In the hot oven, the sweet potato wedges start to dry out on the outside while the inside stays soft. The high heat drives off some moisture from the surface, so the edges can brown and crisp instead of steaming and going soggy. At the same time, the natural sugars in the sweet potatoes warm up and start to taste sweeter and more intense as they cook through.

As the wedges bake, the olive oil coats every side and keeps the spices stuck in place. That thin layer of oil also lets the outside brown more evenly, so the wedges come out with a light crust instead of a pale, soft surface. The smoked paprika, cinnamon, garlic powder, onion powder, and cayenne spread over each piece, so every wedge tastes the same from end to end.

Flipping the wedges halfway through gives more sides a chance to sit directly on the hot pan. By the time they are done, the outsides are browned and a little crisp, while the centers stay tender and creamy.

Mistakes To Avoid

Cutting the sweet potatoes into very different sizes makes them cook unevenly. Smaller pieces turn dark and hard before the bigger wedges are even soft in the center, so the tray ends up with a mix of burnt bits and undercooked, firm pieces.

Crowding the wedges on the baking sheet causes them to steam instead of roast. When they sit too close, moisture stays trapped between them, so the outsides stay soft and pale instead of getting browned and a little crisp.

Letting the oven run cooler than 425°F keeps the wedges from ever really crisping. At a lower heat, they slowly dry out and turn leathery, with edges that never get that roasted, slightly blistered surface.

Skipping the toss with oil or not using enough oil leaves the spice mix dry and patchy. The seasoning then sits in clumps and can burn in spots, while the bare parts of the wedges stay bland and a bit tough on the surface.
