Sweet Potato Fries Recipe

Preheat and prepare

Preheat oven to 425°F (220°C). Line a large baking sheet with parchment paper or a silicone mat. If using a convection setting, reduce temperature to 400°F (200°C).

Cut sweet potatoes

Wash and dry sweet potatoes thoroughly. Trim ends. Cut into evenly sized batons about 1/3 to 1/2 inch thick so fries cook uniformly. The listed 2 cups corresponds to about 1 large sweet potato (adjust if making more).

Soak (optional but recommended)

Place cut fries in a bowl of cold water and soak 20–30 minutes to remove excess starch (helps crispness). If short on time, soak 10 minutes. After soaking, drain and thoroughly pat fries dry with clean kitchen towels or paper towels.

Coat fries

Put the dried fries in a large bowl. Sprinkle the cornstarch over the fries and toss gently to coat evenly (this creates a light, crisp exterior). Drizzle the olive oil over the fries and toss until evenly coated. Add sea salt, black pepper, smoked paprika, and garlic powder; toss again so seasonings distribute evenly.

Arrange on baking sheet

Spread fries in a single layer on the prepared baking sheet with a little space between pieces — avoid overcrowding which causes steaming. For best crispiness, leave an inch or two between fries where possible.

Bake and flip

Bake in the preheated oven for 20 minutes. After 20 minutes, remove the sheet and use a spatula to flip each fry or turn the pan to rotate fries for even browning. Return to oven and bake another 10–15 minutes, until edges are crisp and centers are tender. Total baking time 30–35 minutes depending on thickness and oven.

Broil for extra crisp

If fries need more color or crispness, broil on high for 1–2 minutes while watching closely to avoid burning. Remove immediately when golden and crisp.

Finish and serve

Transfer fries to a serving bowl or platter. Sprinkle with chopped fresh parsley if using and adjust salt to taste. Serve hot with dipping sauce or condiments of choice.

While fries bake, whisk together mayonnaise, sriracha, lime juice, honey, and 1/8 tsp salt in a small bowl until smooth. Taste and adjust heat or sweetness as desired. Chill until ready to serve.
