Baked Sweet Potato Chips Recipe


  • Author: Katherine

Ingredients

  • 4 large sweet potatoes: The star of the show! Sweet potatoes are not only delicious but also packed with nutrients like Vitamin A, Vitamin C, and fiber. When choosing sweet potatoes, look for firm potatoes without bruises or blemishes. The size is important for even cooking – large potatoes are easier to slice uniformly.

    • Variations: While this recipe specifically calls for sweet potatoes, you could experiment with other root vegetables like yams (often confused with sweet potatoes but slightly drier and starchier), or even regular potatoes for a different flavor profile. However, sweet potatoes offer a unique sweetness and vibrant color that works particularly well in this recipe.
    • Choosing the Right Sweet Potato: There are different varieties of sweet potatoes, often categorized by their flesh color – orange, white, or purple. For this recipe, orange-fleshed sweet potatoes are ideal due to their moisture content and sweetness, which crisp up beautifully in the oven. Avoid overly soft or sprouted sweet potatoes, as these may be less flavorful and harder to slice evenly.
    • Nutritional Powerhouse: Sweet potatoes are an excellent source of beta-carotene, which the body converts to Vitamin A, crucial for vision, immune function, and skin health. They are also a good source of fiber, promoting digestive health and helping you feel full and satisfied. Compared to regular potatoes, sweet potatoes are generally lower on the glycemic index, meaning they cause a slower and steadier rise in blood sugar levels.

  • 1 tablespoon olive oil: Olive oil is used to coat the sweet potato slices, helping them to crisp up in the oven and preventing them from drying out. It also adds a subtle richness and healthy fats to the chips.

    • Variations: While olive oil is a great choice for its flavor and health benefits, you can also use other oils with a high smoke point, such as avocado oil, coconut oil (refined for neutral flavor), or even grapeseed oil. Each oil will impart a slightly different flavor profile. Avocado oil is very neutral and has a high smoke point, making it an excellent alternative. Coconut oil can add a subtle sweetness, while grapeseed oil is also neutral and light.
    • Benefits of Olive Oil: Olive oil, particularly extra virgin olive oil, is rich in monounsaturated fats, considered heart-healthy fats. It also contains antioxidants and anti-inflammatory compounds. When baking at high temperatures, using an oil with a high smoke point is crucial to prevent it from breaking down and producing unhealthy compounds. Olive oil, especially light or refined olive oil, works well in baking.

  • 1½ teaspoons chili powder: Chili powder provides a warm, smoky, and slightly spicy flavor that complements the sweetness of the sweet potatoes perfectly. It adds depth and complexity to the chips, preventing them from being overly sweet.

    • Variations: The beauty of spice blends is their versatility! You can easily adjust the flavor profile by using different chili powders or adding other spices. For a milder flavor, use a mild chili powder or reduce the amount. For more heat, add a pinch of cayenne pepper or use a spicier chili powder blend. You can also experiment with smoked paprika for a deeper smoky flavor, cumin for warmth, garlic powder for savory notes, or even a touch of cinnamon for a sweeter, more Moroccan-inspired flavor.
    • Understanding Chili Powder: Chili powder is typically a blend of dried chili peppers and other spices, such as cumin, oregano, garlic powder, and paprika. The exact composition can vary depending on the brand and type of chili powder. Always check the label if you are sensitive to certain spices or want a specific flavor profile. For this recipe, a standard chili powder blend works wonderfully.

  • ½ teaspoon kosher salt: Salt is essential for enhancing the flavors of all the other ingredients and balancing the sweetness of the sweet potatoes. Kosher salt is preferred by many cooks because of its larger crystals, which make it easier to pinch and distribute evenly.

    • Variations: You can use other types of salt, such as sea salt or table salt. Sea salt often has a slightly coarser texture and may contain trace minerals. Table salt is finely ground and may contain iodine. Adjust the amount of salt to your taste. For a more intense salty flavor, you can use flaky sea salt and sprinkle it on the chips after baking.
    • Importance of Salt: Salt not only enhances flavor but also plays a role in the texture of the chips. It helps to draw out moisture from the sweet potatoes, which contributes to crispier chips. Don’t be afraid to season generously, but start with the recommended amount and adjust to your liking.

  • ⅛ teaspoon seasoned salt such as Lawry’s, to taste: Seasoned salt adds another layer of savory flavor complexity. Lawry’s is a popular brand, but other seasoned salt blends will work as well. Use it to taste, as some seasoned salts can be quite salty.

    • Variations: If you don’t have seasoned salt, you can easily create a similar flavor by adding a pinch of garlic powder, onion powder, and paprika to your salt mixture. You can also experiment with other seasoning blends, such as Cajun seasoning, Italian seasoning, or even a simple blend of black pepper and garlic powder. For a healthier option, you can skip the seasoned salt altogether or use a low-sodium version.
    • Homemade Seasoned Salt: Making your own seasoned salt allows you to control the ingredients and sodium content. A simple homemade version can be made by combining salt with garlic powder, onion powder, paprika, and a pinch of turmeric for color. You can adjust the ratios to your preference.


Instructions

  1. Preheat oven to 425°F. Lightly oil a baking sheet (or line with foil and oil). Set aside. Preheating the oven to the correct temperature is crucial for even cooking and crisping. The high temperature helps to quickly evaporate moisture from the sweet potatoes, resulting in crispy chips rather than soggy ones.

    • Why 425°F? This temperature is hot enough to promote crisping but not so hot that the chips burn before they are cooked through. It strikes a good balance for achieving both tenderness and crispness.
    • Oiling the Baking Sheet: Oiling the baking sheet prevents the chips from sticking and ensures they release easily once baked. You can use olive oil, avocado oil, or cooking spray. Alternatively, lining the baking sheet with foil or parchment paper makes cleanup easier. If using foil, lightly oil it to prevent sticking. Parchment paper is naturally non-stick and is a great option for even baking.
    • Oven Thermometer: Oven temperatures can vary, so using an oven thermometer is a good way to ensure your oven is accurately preheated to 425°F. This will help you achieve consistent results.

  2. Using a mandoline slicer or a very sharp knife, cut the sweet potatoes into thin slices (¼ inch for thicker chips or ⅛ inch for thinner chips). The thickness of the sweet potato slices directly affects the cooking time and crispiness. Thinner slices will cook faster and become crispier, while thicker slices will be slightly softer in the center.

    • Mandoline Slicer: A mandoline slicer is highly recommended for achieving uniformly thin slices quickly and easily. It ensures consistent thickness, which is essential for even cooking. If using a mandoline, be extremely careful and use the safety guard to protect your fingers.
    • Sharp Knife: If you don’t have a mandoline, a very sharp knife is essential. Use a chef’s knife or a similar large, sharp knife. Take your time and aim for even slices. It helps to cut a flat base on the sweet potato first to prevent it from rolling around while slicing.
    • Thickness Matters: For truly crispy chips, aim for slices that are ⅛ inch thick or even slightly thinner. ¼ inch slices will be less crispy but still delicious. Experiment with different thicknesses to find your preferred texture. Thicker slices may require a slightly longer baking time.
    • Even Slicing Tips: To ensure even slices, hold the sweet potato firmly and use a consistent slicing motion. If using a knife, you can score the sweet potato lengthwise and then slice along the score marks to guide your cuts.

  3. Combine the olive oil and seasonings in a large bowl. Mixing the oil and seasonings together first ensures that the spices are evenly distributed and coat the sweet potato slices effectively.

    • Large Bowl: Use a large bowl to provide ample space for tossing the sweet potatoes and seasonings without overcrowding. A stainless steel or glass bowl works well.
    • Mixing Thoroughly: Whisk or stir the olive oil, chili powder, kosher salt, and seasoned salt together until well combined. This creates a flavorful coating for the chips.

  4. Add the cut sweet potatoes; toss gently to coat. Gently tossing the sweet potato slices with the seasoned oil ensures that each slice is evenly coated with the flavor and oil, which is crucial for crisping and even baking.

    • Gentle Tossing: Avoid being too rough when tossing, as you don’t want to break or bruise the sweet potato slices. Use your hands or two large spoons to gently toss and turn the slices until they are all coated with the oil and spices.
    • Even Coating: Make sure every slice is coated with the oil mixture. This will help them crisp up evenly in the oven and prevent them from drying out. If needed, add a little more olive oil to ensure all slices are lightly coated.

  5. Place the potatoes in a single layer on the prepared baking sheet. Arranging the sweet potato slices in a single layer is absolutely essential for achieving crispy chips. Overcrowding the baking sheet will cause the chips to steam instead of bake, resulting in soggy chips.

    • Single Layer Importance: When the chips are in a single layer, hot air can circulate around each slice, allowing moisture to evaporate and the chips to crisp up properly. If they are piled on top of each other, they will trap moisture and become soggy.
    • Baking in Batches: If you have a lot of sweet potato slices, it’s better to bake them in batches rather than overcrowding a single baking sheet. Use multiple baking sheets if necessary or bake in two batches to ensure crispiness.
    • Spacing: Leave a little space between each slice on the baking sheet to allow for air circulation. Don’t stack or overlap the slices.

  6. Bake, turning once, until golden and tender, about 10 minutes on each side. Baking the chips in two stages, flipping them halfway through, ensures even cooking and crisping on both sides. The baking time may vary depending on the thickness of the slices and your oven.

    • Turning Halfway: Flipping the chips halfway through baking allows both sides to be exposed to the hot oven air, promoting even crisping. Use a spatula to carefully flip each slice.
    • Doneness Check: The chips are done when they are golden brown around the edges and tender when pierced with a fork. They should also be slightly crispy to the touch. Avoid overbaking, as they can become too hard or burnt.
    • Baking Time Variation: Keep an eye on the chips and adjust the baking time as needed. Thinner slices will bake faster, while thicker slices may require a few extra minutes. Oven temperatures can also vary, so use the baking time as a guideline and rely on visual cues and tenderness to determine doneness.

  7. After roasting, broil on each side on high for just a couple of minutes. Watch them closely to make sure they do not burn. Broiling is an optional but highly recommended step to achieve extra crispiness and a slightly caramelized edge on the chips. However, broiling requires close attention as chips can burn quickly under the broiler.

    • Broiling for Crispness: The intense heat of the broiler quickly crisps up the surface of the chips and adds a beautiful golden-brown color. It also enhances the flavor and texture.
    • Watch Closely: Broiling is very fast, so you need to watch the chips constantly to prevent them from burning. Stay right by the oven and check them every minute or even every 30 seconds.
    • Broiling Technique: Position the baking sheet about 4-6 inches from the broiler element. Broil on high for 1-2 minutes per side, or until the chips are golden brown and crispy. Flip them once during broiling. If they start to burn in spots, remove them from the broiler immediately.

  8. Serve with your favorite dipping sauces! Baked sweet potato chips are delicious on their own, but they are even better with dipping sauces. Let them cool slightly after baking, as they will crisp up further as they cool.

    • Cooling Slightly: Allowing the chips to cool for a few minutes after baking helps them to crisp up fully. They will be slightly softer when hot out of the oven but will become crispier as they cool.
    • Dipping Sauce Ideas: The possibilities for dipping sauces are endless! Consider serving them with classic ketchup, ranch dressing, honey mustard, or aioli. For a healthier option, try Greek yogurt-based dips, hummus, guacamole, or salsa. Spicy mayo, sriracha aioli, or chipotle mayo are also great choices for those who like a little heat. Experiment with different flavors to find your favorites!
