What Makes This Recipe Special

Using cornstarch ensures an extra crunch, while the drizzle of olive oil adds richness and aids in even cooking.

What’s great about this recipe is the flavor profile; you can customize it with various optional spices depending on your mood or preference. From a pinch of cayenne pepper for heat to garlic powder for an aromatic kick, you have the freedom to create your perfect fry!

Ingredients

2 pounds sweet potatoes: Fresh, firm sweet potatoes will yield the best results.
1 tablespoon cornstarch: This is the magic ingredient that helps achieve that coveted crispiness.
1/2 teaspoon fine sea salt: Enhances flavor while keeping it balanced.
2 tablespoons extra-virgin olive oil: Adds healthy fats and helps with browning.
Optional spices: Freshly ground black pepper, cayenne pepper, garlic powder can be added for extra flavor.

Ingredient Notes and Easy Substitutions

Sweet Potatoes: Look for sweet potatoes that are firm and without blemishes. You can swap sweet potatoes for regular potatoes if you’re in a pinch, although the flavor will change.
Cornstarch: If you don’t have cornstarch, you can use arrowroot powder or even potato starch; they all offer similar properties.
Olive Oil: Feel free to substitute with vegetable oil or coconut oil for a different flavor dimension.

Instructions

Preheat the oven to 425°F (220°C) and line two baking sheets with parchment paper to prevent sticking and promote even browning.
Peel and cut the sweet potatoes into fry-shaped pieces. Aim for uniform sizes to ensure even cooking.
Place the fries on the baking sheets. Sprinkle with cornstarch and salt, then drizzle with olive oil. Toss everything well to coat evenly.
Arrange fries in a single layer without overcrowding them. Bake for 20 minutes. This initial bake time will help them start to soften and get crispy on the edges.
After 20 minutes, flip the fries and bake for an additional 10 to 18 minutes, or until they are golden brown and crispy. Keep an eye on them to prevent burning!
Toss with optional seasonings if desired and serve hot, straight from the oven.

Expert Tips for the Best Results

Cut the fries evenly: Uniform size helps achieve even cooking and texture.
Avoid overcrowding the baking sheets: This ensures each fry gets ample air circulation for that crispy finish.
Preheat your oven: A well-heated oven ensures a better crunch.
Experiment with spices: Don’t hesitate to try out new spices or seasoning blends to find your favorite combinations!

Variations

Spicy Thai Sweet Potato Fries: Toss with garlic powder, cayenne pepper, and a squeeze of lime before serving.
Herb-Infused Fries: Add dried herbs like rosemary or thyme for a fragrant twist.
Parmesan Sweet Potato Fries: Right after baking, sprinkle some grated parmesan cheese for a cheesy finish.
BBQ Sweet Potato Fries: Drizzle with your favorite BBQ sauce and a dash of smoked paprika for a smoky flavor.
Sweet Cinnamon Fries: Sprinkle with cinnamon and a little sugar before baking for a sweet treat.

Serving Suggestions

Crispy Baked Sweet Potato Fries can elevate any meal. They pair perfectly with:

Dips: Serve them with ranch dressing, guacamole, or spicy ketchup.
Toppings: Consider topping them with avocado, sour cream, or feta cheese for an extra layer of flavor.
As a Side Dish: These fries can complement grilled chicken, burgers, or a hearty salad.

Storage and Reheating

Store leftover fries in an airtight container in the refrigerator for up to 3 days.
To reheat, place them in the oven at 350°F for about 10 minutes, allowing them to regain their crispiness. Microwaving may leave them soggy, so the oven is preferred.

Common Mistakes to Avoid

Cutting fries too thick: Thicker fries will take longer to cook and may end up soggy.
Not drying the sweet potatoes: If they are wet after washing, the moisture can prevent crispiness. Pat them dry before coating.
