Ingredients

• Sweet Potatoes: 2 large sweet potatoes, or about 1.5 pounds. Choose firm sweet potatoes, preferably of similar size for even cooking. They are the star of the show, providing sweetness, vibrant color, and essential nutrients.
• Olive Oil: 2 tablespoons. Extra virgin olive oil is recommended for its healthy fats and mild flavor, but other oils like avocado oil or coconut oil (melted) can also be used. Oil is crucial for crisping up the chips and preventing them from drying out.
• Salt: 1 teaspoon, or to taste. Sea salt or kosher salt are great choices for enhancing flavor. Salt draws out moisture from the sweet potatoes, which contributes to crispiness.
• Black Pepper: ½ teaspoon, or to taste. Freshly ground black pepper adds a subtle warmth and depth of flavor, balancing the sweetness of the potatoes.
• Spices (Optional): ½ teaspoon each (or to taste) of paprika, garlic powder, onion powder, or your favorite spice blend. Spices elevate the flavor profile and allow for customization. Consider chili powder for a kick, or cinnamon for a sweeter chip.

Instructions

1. Preheat the Oven and Prepare Baking Sheets: Preheat your oven to 400°F (200°C). Line two large baking sheets with parchment paper. Parchment paper prevents sticking and makes cleanup a breeze. Using two baking sheets ensures that the chips are spread out in a single layer, which is essential for even baking and crispiness. If you overcrowd the pan, the chips will steam instead of bake, resulting in soggy chips.
2. Wash and Prepare the Sweet Potatoes: Thoroughly wash the sweet potatoes under cold running water. There’s no need to peel them if you prefer the added nutrients and rustic texture of the skin, but you can peel them if you prefer a smoother chip. If keeping the skin on, scrub them well to remove any dirt.
3. Slice the Sweet Potatoes: This is the most crucial step for achieving crispy chips! Thinly slice the sweet potatoes into uniform rounds, about ⅛-inch thick. A mandoline slicer is ideal for achieving consistent, thin slices quickly and easily. If you don’t have a mandoline, use a sharp knife and take your time to slice them as evenly as possible. Thinner slices will crisp up better than thicker slices. Aim for uniformity to ensure even cooking.
4. Soak the Sweet Potato Slices (Optional but Recommended): Place the sliced sweet potatoes in a bowl of cold water and let them soak for at least 30 minutes, or up to 1 hour. Soaking removes excess starch from the sweet potatoes. This is a key step for achieving maximum crispiness. The starch on the surface of the potatoes can prevent them from crisping up properly. If you’re short on time, you can skip this step, but soaking significantly improves the texture. After soaking, drain the sweet potatoes thoroughly and pat them completely dry with paper towels or a clean kitchen towel. Excess moisture is the enemy of crispy chips!
5. Toss with Oil and Seasonings: In a large bowl, gently toss the dried sweet potato slices with olive oil, salt, pepper, and any optional spices you are using. Ensure that each slice is lightly coated with oil and seasonings. Tossing in a bowl allows for even distribution of oil and spices, ensuring every chip is flavorful and crisps up nicely.
6. Arrange on Baking Sheets: Spread the seasoned sweet potato slices in a single layer on the prepared baking sheets. Make sure the slices are not overlapping, as this will prevent them from crisping properly. If necessary, bake in batches to avoid overcrowding. Spacing is crucial for air circulation and even baking.
7. Bake: Bake in the preheated oven for 20-30 minutes, flipping the chips halfway through. The baking time will depend on the thickness of your slices and your oven. Keep an eye on them and bake until they are golden brown and crispy around the edges. Flipping ensures even browning and crisping on both sides. The chips are ready when they are easily removable from the parchment paper and have a nice, golden-brown color.
8. Cool and Crisp Up: Once baked, remove the baking sheets from the oven and let the sweet potato chips cool on the baking sheets for a few minutes. As they cool, they will crisp up further. Resist the urge to eat them immediately, as they will be a bit soft straight out of the oven. Cooling allows the residual heat to continue crisping them. For extra crispiness, you can transfer the chips to a wire rack to cool completely. This allows air to circulate all around the chips, preventing them from getting soggy on the bottom.
9. Serve and Enjoy: Serve the crispy baked sweet potato chips immediately for the best crispness. They are delicious on their own, or with your favorite dipping sauce. Store any leftover chips in an airtight container at room temperature, but they are best enjoyed fresh. Reheating may soften them slightly.

Additional Tips for Crispy Perfection

1. Uniform Slicing is Key: Invest in a mandoline slicer or take extra care to slice the sweet potatoes as thinly and evenly as possible. Consistent thickness ensures even cooking and crispiness. Thicker slices will take longer to cook and may not get as crispy, while uneven slices will cook at different rates, leading to some burnt and some soggy chips.
2. Don’t Skip the Soaking: Soaking the sweet potato slices in cold water is crucial for removing excess starch, which is essential for crispiness. This step makes a noticeable difference in the final texture of the chips. The longer you soak them (up to an hour), the crispier they will be.
3. Dry Them Thoroughly: After soaking, make sure to pat the sweet potato slices completely dry with paper towels or a clean kitchen towel before tossing them with oil and seasonings. Excess moisture will steam the chips in the oven, preventing them from crisping up. Dry slices will roast and crisp up beautifully.
4. Use Enough Oil, But Not Too Much: A light coating of oil is necessary for crisping and flavor. Too little oil will result in dry, tough chips, while too much oil can make them greasy. Two tablespoons of olive oil for two large sweet potatoes is usually the right amount. Toss them gently to ensure even coating.
5. Don’t Overcrowd the Baking Sheet: Spread the sweet potato slices in a single layer on the baking sheet, ensuring they are not overlapping. Overcrowding will cause them to steam instead of bake and crisp. Use two baking sheets if necessary to give the chips enough space. Good air circulation is key for crispiness.
6. Bake at the Right Temperature: Baking at 400°F (200°C) is ideal for achieving crispy baked sweet potato chips. This temperature is high enough to promote crisping but not so high that they burn before cooking through. Lower temperatures will result in softer, less crispy chips.
7. Flip Halfway Through: Flipping the chips halfway through baking ensures even browning and crisping on both sides. This is important for achieving uniform texture and preventing one side from becoming soggy.
8. Let Them Cool Completely (Almost): Allow the baked sweet potato chips to cool on the baking sheet for a few minutes after removing them from the oven. They will continue to crisp up as they cool. For extra crispiness, transfer them to a wire rack to cool completely. Resist the urge to eat them piping hot from the oven, as they will be softer.

Reheating them in a low oven or air fryer for a few minutes may help to crisp them up slightly, but they will never be quite as crispy as freshly baked.

Q6: Can I make these ahead of time?
A: Baked sweet potato chips are best enjoyed fresh for optimal crispness. While you can slice the sweet potatoes ahead of time and store them in cold water in the refrigerator for a few hours to save time, it’s best to bake them closer to serving time. Baking them too far in advance will result in loss of crispness.

Q7: Can I bake these at a lower temperature for longer?
A: Baking at a lower temperature for longer will likely result in softer, less crispy chips. The higher temperature of 400°F (200°C) is crucial for achieving that desirable crispy texture. Lower temperatures may steam the chips instead of roasting them.

Q8: Are baked sweet potato chips healthier than regular potato chips?
A: Yes, baked sweet potato chips are generally considered a healthier option than fried potato chips and even regular baked potato chips. Sweet potatoes are packed with Vitamin A, fiber, and antioxidants. Baking instead of frying significantly reduces the fat content. They are a more nutritious and wholesome snack choice compared to processed potato chips.
