They’re crisp-edged, jewel-toned, slightly sweet, deeply savory, and the kind of thing people “just try one of” and then don’t stop.
Purple sweet potatoes have this creamy interior and almost nutty flavor that regular fries can’t touch. And when roasted properly? They get golden on the edges and stay soft in the center — dramatic in the best way.
If you want extra crisp without drying them out, let the cut fries sit uncovered for 10–15 minutes before baking. A little surface moisture evaporates, and crispiness improves dramatically. It’s a small move with big payoff.
Preheat your oven to 425°F. If you have convection — use it. This is one of the few times it truly earns its keep.
Cut with intention Leave the skins on (that’s where the nutrients and texture live). Slice into evenly sized fries — not too thin or they’ll burn, not too thick or they’ll steam. Aim for ¼–½ inch. Spread them out on a large, heavy baking sheet.
Season smart In a small bowl, whisk together avocado oil, rosemary, oregano, salt, garlic powder, and pepper. Drizzle over the fries and toss directly on the pan until everything is lightly coated. Arrange in a single layer. No overlapping. This is not a pile situation.
Roast + flip Bake for 15 minutes, then flip with a metal spatula. Return to the oven for another 10–13 minutes, until the edges are crisp and the bottoms are golden and slightly caramelized. They should look confident.
Finish like you mean it Sprinkle with flaky sea salt and a little extra chopped herb while hot. Serve immediately.
