2 Tbsp olive oil Helps the coating adhere and promotes browning.

1 Tbsp cornstarch Creates a ultra‑crisp exterior.

½ tsp sea salt Adjust to taste; kosher works well.

¼ tsp freshly ground black pepper Adds subtle heat.

Instructions

Crispy Sweet Potato Fries With Rosemary for Holiday Side Dishes

Prep the potatoes

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

Pro Tip: Very dry fries crisp faster; use a salad spinner or paper towels.

Season and coat

In a large bowl, toss the dried fries with olive oil, cornstarch, salt, pepper, and chopped rosemary until evenly coated. The cornstarch should form a thin dusting that clings to each stick.

Pro Tip: Add the seasoning in batches to avoid soggy fries.

Arrange for baking

Line a baking sheet with parchment. Spread the fries in a single layer, leaving space between each piece. Overcrowding traps steam and prevents crispness.

Pro Tip: Use two sheets if needed; rotate halfway through baking.

Bake to golden crisp

Bake in a pre‑heated 425°F (220°C) oven for 20‑25 minutes, flipping halfway. Fries are done when edges are deep amber and the interior is tender.

Pro Tip: If you like extra crunch, broil for the last 2 minutes, watching closely.

Finish and serve

Transfer fries to a serving platter, sprinkle a pinch of extra sea salt if desired, and serve immediately with your favorite holiday dipping sauce.

Pro Tip: A drizzle of warmed maple‑mustard sauce adds a sweet‑tangy finish.

Expert Tips

Tip #1: Uniform cuts

Use a mandoline or a sharp chef’s knife to cut sticks of the same thickness. Even pieces bake uniformly, preventing some fries from being soggy while others burn.

Tip #2: Double‑bake for extra crunch

After the first bake, let fries rest 5 minutes, then return to the oven for another 5‑7 minutes. This extra dry‑out step creates a restaurant‑style crunch.

Tip #3: Flavor boost

Add a pinch of smoked paprika or cayenne to the seasoning mix for a subtle heat that complements the rosemary without overwhelming the sweet potato’s natural flavor.

Tip #4: Serve hot

These fries lose crispness quickly. Keep them on a wire rack over a baking sheet for a few minutes before plating to retain airflow and crunch.

Frequently Asked Questions

Frozen fries contain added moisture, which hinders crisping. For best results, stick to fresh sweet potatoes and dry them thoroughly before coating.

Substitute with an equal amount of arrowroot powder or potato starch. Both create a light, crisp coating similar to cornstarch.

Absolutely! A maple‑mustard dip, garlic aioli, or a simple honey‑yogurt sauce pairs beautifully with the rosemary‑infused fries.

Cool the fries completely, then store in an airtight container in the refrigerator for up to 2 days. Re‑crisp in a hot oven (425°F) for 5 minutes before serving.
