Yields: 4-6 servings
Prep time: 25 minutes
Cook time: 25-35 minutes
Ingredients:
- 2 large sweet potatoes (about 1 ½ – 2 pounds total), peeled
- 2 tablespoons cornstarch (or potato starch)
- 1 teaspoon smoked paprika
- ½ teaspoon garlic powder
- ¼ teaspoon onion powder
- ½ teaspoon salt (plus more to taste after cooking)
- ¼ teaspoon black pepper
- 2-3 tablespoons olive oil or avocado oil
Equipment:
- Large bowl
- Sharp knife or mandoline
- Baking sheet(s)
- Parchment paper (recommended)
- Small bowl for seasoning
Step-by-Step Pictures and Instructions:
Step 1: Prepare the Sweet Potatoes
- Wash and peel the sweet potatoes.
- Cut the sweet potatoes into fries, about ½ inch thick. Aim for even thickness for consistent cooking. You can use a sharp knife or a mandoline for this.
Step 2: Soak the Fries (Crucial for Crispiness)
- Place the cut sweet potato fries in a large bowl and cover them with cold water.
- Let them soak for at least 30 minutes, or up to 2 hours. Soaking helps remove excess starch, which leads to crispier fries.
Step 3: Dry the Fries Thoroughly (Another Key to Crispiness)
- Drain the water from the bowl.
- Lay the fries out in a single layer on a clean kitchen towel or several layers of paper towels. Pat them very dry. The drier they are, the crispier they will get.
Step 4: Toss with Cornstarch and Seasonings
- Transfer the dried sweet potato fries to a clean large bowl.
- Sprinkle the cornstarch evenly over the fries. Toss gently to coat them thoroughly. The cornstarch helps create a crispy exterior.
- In a small bowl, combine the smoked paprika, garlic powder, onion powder, salt, and pepper. Sprinkle this mixture over the fries.
- Drizzle the olive oil (or avocado oil) over the fries. Toss everything gently but thoroughly until the fries are evenly coated with the cornstarch, seasonings, and oil.
Step 5: Arrange on Baking Sheets
- Preheat your oven to 400°F (200°C).
- Line baking sheet(s) with parchment paper for easier cleanup and to prevent sticking.
- Arrange the seasoned sweet potato fries in a single layer on the prepared baking sheet(s). Avoid overcrowding the pan, as this will steam the fries instead of making them crispy. If necessary, use two baking sheets.
Step 6: Bake the Fries
- Bake for 25-35 minutes, flipping the fries halfway through (around 12-15 minutes), until they are golden brown and crispy on the edges.
- Keep a close eye on them during the last few minutes of baking to prevent burning.
Step 7: Serve and Enjoy!
- Once the fries are crispy and golden, remove them from the oven.
- Taste and add more salt if needed.
- Serve immediately while they are at their crispiest. Enjoy them on their own or with your favorite dipping sauce like ketchup, aioli, or ranch.
Tips for Extra-Crispy Fries:
- Soaking is key: Don’t skip the soaking step! It removes surface starch for better crisping.
- Dry thoroughly: Ensure the fries are completely dry before tossing with cornstarch and oil.
- Don’t overcrowd the pan: Give the fries space so they can crisp up instead of steaming. Bake in batches if necessary.
- High heat: Baking at a higher temperature helps to achieve crispiness.
- Consider a double bake: For extra crispiness, you can bake the fries for 15 minutes, let them cool slightly, then bake for another 10-15 minutes at the same temperature.
- Air Fryer Option: These fries can also be made in an air fryer. Preheat your air fryer to 400°F (200°C). Cook in batches, ensuring a single layer, for 15-20 minutes, flipping halfway through, until golden and crispy.
Enjoy your delicious and perfectly crispy sweet potato fries!
