Ingredients

4 Sweet Potatoes
2 Tablespoons Corn starch for crisper fries
Salt to taste
black pepper to taste
2 Tablespoons Olive oil
Parsley optional (for garnish)

For the Spicy Dipping Sauce

1 cup ketchup
1 Tablespoon Worcestershire sauce
2 teaspoons spicy horseradish
2 teaspoons brown sugar
1 ½ teaspoons cayenne pepper
½ teaspoon garlic salt

Instructions

Preheat your oven to 425°F (220°C). A hot oven is key to getting that crispy exterior while keeping the inside tender.
Peel the sweet potatoes using a vegetable peeler. For the best results, choose medium to large sweet potatoes that are relatively straight — they’re easier to cut into even fries.
Slice each sweet potato lengthwise into ¼-inch thick slices. Then cut those slices into fry-shaped strips, about ¼ to ½ inch wide. Try to keep the fries as uniform in size as possible so they cook evenly. (Thinner fries will get crispier, while slightly thicker ones stay softer in the center.)
Place your cut sweet potato fries into a large gallon-size Ziploc bag.
Sprinkle 1–2 tablespoons of cornstarch over the fries (depending on how many potatoes you’re using). Seal the bag, then gently shake and turn it until all the fries are evenly coated with a light layer of cornstarch.
Drizzle a light coat of olive oil onto one or two large baking sheets and spread it evenly with a pastry brush or your fingers.Alternatively, for easier cleanup and to prevent sticking, line your baking sheet(s) with parchment paper — no oil needed on the paper itself.
Add the cornstarch-coated sweet potato fries to the prepared baking sheet(s) in a single layer, making sure the fries are not touching or overcrowded. This gives them room to crisp up properly. You will likely need two baking sheets depending on how many sweet potatoes you’re cooking.
Arrange the cornstarch-coated fries in a single layer across your prepared baking sheet(s), making sure they are not touching or overcrowded. Use two baking sheets if needed so the fries have plenty of space — this is essential for achieving maximum crispiness.
Lightly sprinkle the fries with salt and freshly ground black pepper. For extra flavor, you can also add a pinch of garlic powder, paprika, or cayenne if you like a little heat.
Place the baking sheets in your preheated 425°F oven and bake for 15 minutes. After 15 minutes, carefully stir or flip the fries using a spatula to ensure even browning. Return them to the oven and bake for an additional 15 minutes, or until the fries are nicely browned and crispy on the outside with tender centers.
While your sweet potato fries are in the oven, prepare the quick and zesty spicy dipping sauce.
.In a small mixing bowl, whisk together the following ingredients until smooth and well combined: ketchup, worcestershire sauce, prepared horseradish, brown sugar, cayenne pepper, and garlic salt. Start with the base amounts and adjust to your preference — add a little more brown sugar for sweetness, extra cayenne for heat, or more horseradish for a bolder kick.
Once the sweet potato fries are beautifully browned and crispy, carefully remove the baking sheets from the oven.
While the fries are still piping hot, immediately sprinkle them with a light dusting of flaky sea salt and chopped fresh parsley. The heat helps the salt and herbs adhere perfectly to the fries, enhancing both flavor and presentation.
Serve the fries right away while they’re at their crispiest, alongside the spicy dipping sauce you prepared earlier.
