2 Tbsp extra‑virgin olive oil Ensures crispness; can substitute avocado oil.

1 Tbsp fresh rosemary, finely chopped If unavailable, use 1 tsp dried rosemary.

½ tsp garlic powder Adds depth without overpowering rosemary.

Optional: pinch of smoked paprika For a subtle smoky note.

Instructions

Prep the potatoes

Peel (if desired) and cut each sweet potato into ¼‑inch sticks. Place in a bowl of cold water for 5 minutes to remove excess starch, then pat completely dry with a clean kitchen towel.

Pro Tip: Drying thoroughly prevents steaming and promotes crispness.

Season & coat

Toss the dried sticks with olive oil in a large bowl, ensuring each piece is lightly coated. Sprinkle sea salt, garlic powder, and smoked paprika (if using); mix until evenly distributed.

Pro Tip: A single thin layer of oil is enough; excess oil will make fries soggy.

Bake the first round

Preheat oven to 425°F (220°C). Spread fries in a single layer on a parchment‑lined baking sheet, ensuring they don’t touch. Bake for 15 minutes, then flip each fry using tongs.

Pro Tip: A hot oven creates the initial crust; avoid overcrowding.

Finish baking & add rosemary salt

Return the sheet to the oven for another 10‑12 minutes, watching for deep golden edges. While still hot, sprinkle the fresh rosemary‑salt mixture over the fries and toss gently to coat.

Pro Tip: Season immediately; the heat helps the herbs adhere.

Serve

Transfer fries to a serving platter. Serve hot with your favorite dip—aioli, ketchup, or a cool yogurt‑herb sauce. Enjoy within 15 minutes for maximum crunch.

Expert Tips

Tip #1: Use a wire rack

Placing the fries on a wire rack set over the baking sheet allows hot air to circulate, boosting crispness on all sides.

Tip #2: Don’t skip the water soak

Soaking removes surface starch that otherwise creates steam, which is the main enemy of a crunchy fry.

Tip #3: Finish with a light drizzle of lemon

A few drops of fresh lemon juice brighten the rosemary flavor and cut any lingering sweetness.

Storage & Variations

Store leftovers in an airtight container in the fridge for up to 2 days; re‑crisp in a hot oven (375°F) for 5 minutes. Swap rosemary for thyme or sage, add a pinch of cayenne for heat, or use sweet potato wedges for a heartier bite.

Frequently Asked Questions

Frozen fries contain moisture and often pre‑seasoning, which can affect crispness. For best results, stick to fresh potatoes and follow the soak‑dry‑bake method.

Combine chopped rosemary, sea salt, and garlic powder in an airtight jar. Store in a cool, dry place for up to two weeks; the flavor intensifies over time.

Check three things: potatoes must be fully dried, the oven should be pre‑heated to 425°F, and the fries need space to breathe. Overcrowding or excess oil are common culprits.
