Whether you’re new to cooking or a seasoned home chef, you’ll find everything you need to master this satisfying side dish.
Why Sweet Potato Fries?
Healthier Alternative to Regular Fries
Sweet potatoes are packed with nutrients, including fiber, vitamins A and C, potassium, and antioxidants. Compared to traditional white potatoes, they have a lower glycemic index and more complex carbohydrates, making them a more balanced option.
Versatile in Flavor
Unlike regular fries, sweet potato fries work with both sweet and savory seasonings. You can go spicy with cayenne and paprika, earthy with rosemary and garlic, or sweet with cinnamon and honey.
Great for All Diets
Sweet potato fries can be adapted for gluten-free, vegan, paleo, or Whole30 diets depending on your cooking method and seasonings. They’re naturally dairy- and gluten-free.
Choosing the Right Sweet Potatoes
Not all sweet potatoes are created equal. For fries, you want to select firm, long, and evenly-shaped sweet potatoes. This ensures even cutting and consistent cooking.
Tips for Selecting Sweet Potatoes
Look for ones with a smooth skin and no bruises or soft spots.
Longer, thinner sweet potatoes are easier to cut into fry shapes.
Avoid overly large or round ones—they tend to cook unevenly.
Prepping Sweet Potato Fries: The Key to Crispiness
Crispiness starts well before baking or frying. Here’s how to prep your fries for that perfect crunch:
Step 1: Peel and Cut Evenly
Peeling is optional, but it gives a smoother texture. Cut the sweet potatoes into even matchstick-sized fries, about 1/4 to 1/2 inch thick. Uniform size ensures even cooking.
Step 2: Soak in Water
Soaking the fries in cold water for at least 30 minutes (or up to 2 hours) removes excess starch, which helps them crisp up in the oven or air fryer.
Step 3: Dry Thoroughly
After soaking, drain and pat the fries completely dry with a clean towel. Moisture is the enemy of crispiness.
Cooking Methods: Baked, Air-Fried, or Deep-Fried
There are several ways to cook sweet potato fries. Each has its pros and cons, depending on your time, health goals, and equipment.
Baked Sweet Potato Fries
Ingredients
2 large sweet potatoes
2 tbsp olive oil or avocado oil
1 tsp cornstarch or arrowroot powder (optional, for extra crispiness)
1 tsp paprika
1/2 tsp garlic powder
Salt and pepper to taste
Instructions
Preheat oven to 425°F (220°C).
Toss the cut, dried sweet potatoes in a bowl with oil, spices, and cornstarch.
Spread them in a single layer on a parchment-lined baking sheet. Make sure they don’t touch.
Bake for 20 minutes, flip, then bake another 10–15 minutes until crispy and golden.
Sprinkle with salt right after removing from the oven.
Air-Fried Sweet Potato Fries
Pros

Less oil needed
Cooks faster
Instructions

Lightly coat fries with oil and seasoning.
Place in a single layer in the basket.

Deep-Fried Sweet Potato Fries
Best for indulgence
If you want that ultra-crispy, restaurant-style finish:
Heat oil (canola, peanut, or avocado) in a deep pot to 350°F (175°C).
Fry in batches for 3–4 minutes until golden.
Drain on a paper towel and sprinkle with seasoning.

Common Mistakes and Fixes
