Ingredients List
To create the perfect crispy oven-baked sweet potato fries, you’ll need the following ingredients:
- 2 large sweet potatoes (about 1 pound each)
- 2 tablespoons olive oil (or avocado oil for a higher smoke point)
- 1 teaspoon sea salt (adjust to taste)
- 1 teaspoon paprika (for a hint of smokiness)
- ½ teaspoon garlic powder (optional, for extra flavor)
- ½ teaspoon black pepper
- 1 tablespoon cornstarch (for extra crispiness)
Substitutions
- Oil: You can substitute olive oil with coconut oil or any other high-quality oil.
- Spices: Feel free to experiment with spices like cayenne pepper for heat, or Italian seasoning for a herby twist.
- Cornstarch: If you prefer a gluten-free option, arrowroot powder works well as a substitute.
Timing
Preparing crispy oven-baked sweet potato fries is a breeze! Here’s a breakdown of the timing:
- Preparation Time: 15 minutes
- Cooking Time: 25-30 minutes
- Total Time: 40-45 minutes
This is approximately 20% less time than many traditional frying methods, allowing you to enjoy a healthier version of fries without sacrificing flavor or crunch.
Step-by-Step Instructions
Step 1: Preheat Your Oven
Preheat your oven to 425°F (220°C). A hot oven is crucial for achieving that crispy texture.
Step 2: Prepare the Sweet Potatoes
- Wash and Peel: Rinse the sweet potatoes under cold water and peel them using a vegetable peeler.
- Cut into Fries: Slice them into even sticks, about ¼ inch thick. Uniformity ensures even cooking.
Step 3: Soak the Fries
Soak the cut sweet potato fries in cold water for at least 30 minutes. This step helps to remove excess starch, which is key to achieving that coveted crispiness.
Step 4: Dry the Fries
After soaking, drain the fries and pat them dry with a clean kitchen towel. Removing moisture is essential for crispiness.
Step 5: Season and Coat
In a large bowl, combine the dried sweet potato fries with olive oil, sea salt, paprika, garlic powder, black pepper, and cornstarch. Toss until evenly coated. The cornstarch will help absorb moisture and create a crunchy exterior.
Step 6: Arrange on a Baking Sheet
Spread the fries in a single layer on a baking sheet lined with parchment paper. Avoid overcrowding the pan to ensure they cook evenly.
Step 7: Bake
Bake in the preheated oven for 25-30 minutes, flipping halfway through. Keep an eye on them during the last few minutes to prevent burning. They should be golden brown and crispy.
Step 8: Serve and Enjoy
Once cooked, remove the fries from the oven and let them cool for a few minutes. Serve immediately with your favorite dipping sauce!

Common Mistakes to Avoid
To ensure your crispy oven-baked sweet potato fries turn out perfectly, avoid these common pitfalls:

- Not Preheating the Oven: Make sure your oven is properly preheated to achieve the desired crunch.
Storing Tips for the Recipe
If you have leftovers (though they may be hard to resist!), here’s how to store them:
- Cool Completely: Allow the fries to cool to room temperature before storing.
- Use an Airtight Container: Place them in an airtight container and store in the refrigerator for up to 3 days.
- Reheat in the Oven: For the best texture, reheat in the oven at 400°F (200°C) for about 10 minutes to regain crispiness.
