Ingredients
Instructions
First, preheat your oven to 375°F (190°C) and position two racks in the upper and lower thirds of the oven. This two-rack setup allows you to bake both trays of chips at the same time, which keeps the process efficient and ensures even browning. While the oven heats up, scrub your sweet potatoes thoroughly under cool running water. You are keeping the skin on because it contains fiber and nutrients, and it also turns beautifully crispy in the oven. Pat them completely dry with a clean kitchen towel—excess moisture can lead to steaming instead of crisping. Now gather your oil, everything bagel seasoning, and a large mixing bowl. Having all your ingredients prepped and measured before you start slicing makes the whole process smoother and more enjoyable.

Now for the most important step: slicing the sweet potatoes into uniformly thin rounds. A mandoline slicer set to 1/8-inch (3-mm) thickness is your best friend here because it guarantees even slices that cook at the same rate. If you don’t have a mandoline, use a very sharp chef’s knife and slice as thinly and evenly as possible—aim for consistent coins about the thickness of a coin. Keep the slices uniform because thicker pieces take longer to crisp and can burn on the edges before the centers become crunchy. As you slice, you may notice the sweet potato slices are slightly starchy and sticky; this is natural. Work in batches if necessary, and place the slices directly into your large bowl. This is a fantastic step to let older kids help with, though be sure to supervise when using a mandoline.

Drizzle the olive oil or avocado oil over the sweet potato slices. Use your hands or a spatula to gently toss and coat every slice with a thin, even layer of oil. The oil is essential because it helps the seasoning adhere and encourages caramelization and crispiness as the chips bake. Too little oil and the chips dry out; too much and they become greasy and take longer to crisp. After the slices are evenly coated, sprinkle the everything bagel seasoning over the top and toss again. The mixture of sesame seeds, poppy seeds, dried garlic, dried onion, and salt clusters in the crevices of the sweet potato, creating pockets of savory flavor in every bite. You want the seasoning well distributed so each chip gets a little flavor, but you don’t need to use every single fleck—some will fall off during baking, and that’s perfectly fine.
Line two large baking sheets with parchment paper or silicone baking mats. Arrange the seasoned sweet potato slices in a single layer, making sure they don’t overlap. Overlapping is the number one reason chips come out soft or unevenly cooked because the covered areas steam instead of crisp. Leave a little space between slices if possible, about 1/4 inch apart, so hot air can circulate freely around each chip. If your sweet potatoes are very large, you may need to bake in batches. Use all the oil and seasoning from the bowl, scraping the sides with a spatula to get every bit of the flavorful coating. This is also the moment to gently press down any curling pieces so they lay flat against the pan, which helps them brown evenly and become crisp on both sides.
Place the baking sheets in the preheated oven on the upper and lower racks. Bake for 15 minutes, then carefully remove both pans from the oven and use a thin metal spatula to flip each chip. Flipping ensures both sides become golden and crispy rather than one side drying out. At this point the chips will look slightly shriveled and may still feel soft, but they will continue to crisp as they bake. Swap the position of the pans (the top pan goes to the bottom and vice versa) to promote even browning, since most ovens have hot spots. Return the pans to the oven and bake for another 8 to 12 minutes, keeping a close eye during the final minutes because sweet potatoes can go from golden to burnt very quickly. Your oven is ready when the edges are deeply golden, the surfaces are mostly dry, and the chips feel fairly rigid when lifted with the spatula.
Once the chips are beautifully browned and crisp, remove the baking sheets from the oven and let the chips cool directly on the pans for at least 10 minutes. This resting period is a critical step in creating crunchy sweet potato chips. As they cool, the moisture inside evaporates and the structure sets, transforming the slices from soft and pliable to crisp and snappy. Do not rush this step by trying to serve them immediately—they will not yet be at their full crunch potential. If any chips still feel slightly soft in the center after cooling, you can return them to the oven for an additional 3 to 5 minutes at 350°F (177°C). Just remember that they will continue to firm up as they cool completely.
When the chips have cooled completely, transfer them to a serving bowl or divide them into lunchbox containers. Serve immediately with a sprinkle of flaky sea salt if you like an extra punch of salt. These sweet potato everything bagel chips are wonderful on their own as a snack, but they also make a fantastic topping for salads, soups, or avocado toast. If you’re packing them for school lunches, let them cool completely before sealing the container, because trapped steam will make them lose their crispness. Store any leftovers in an airtight container at room temperature for up to 3 days—assuming they last that long! For longer storage, you can place a paper towel in the container to absorb excess moisture, and re-crisp them in a low oven if needed.
For best results
- Use a mandoline for perfectly even slices: This is the single most important tool for achieving restaurant-quality sweet potato chips. A mandoline slicer gives you consistent thickness every time, which is nearly impossible to replicate with a knife alone. Set it to 1/8 inch (3 mm) for the ideal balance between crispness and a tender interior. If you don’t own a mandoline, try slicing the sweet potatoes as thinly as you can with a sharp chef’s knife, working slowly and carefully. You can also use a food processor with a slicing attachment for a quicker, still-uniform result. Just remember that the thinner the slice, the faster it bakes and the crispier it gets, but super-thin slices can burn easily, so check often during the last few minutes.
- Don’t overcrowd the baking sheet: Overlapping sweet potato slices trap steam and prevent air circulation, causing soft and chewy spots instead of crisp chips. Spread the slices in a single layer with a little space around each one. If you’re doubling the recipe, use two baking sheets and rotate them halfway through baking. If your pans are small, bake in batches rather than piling slices on top of each other. The extra time spent baking in batches is well worth the result. You can also use parchment paper or silicone baking mats to prevent sticking and make cleanup effortless, but parchment is more convenient for the high heat and quick turnover.
- Flip and rotate for even browning: Sweet potato chips can be temperamental when it comes to browning. The sugars in sweet potatoes caramelize quickly, so one side might brown faster than the other. About halfway through baking, flip each chip using a thin spatula or tongs to expose the other side to the heat. This also releases built-up moisture and promotes an even golden color. At the same time, swap the baking sheets between the upper and lower racks so every chip gets equal exposure to the oven’s heat zones. These two simple actions—flipping and rotating—are the secret to evenly crunchy, beautifully golden chips every single time.
- Let the chips cool completely before storing: The cooling process is not just a suggestion—it's essential for achieving that crisp, crunchy texture. When sweet potato chips come out of the oven, they still contain moisture in their centers. As they cool, this moisture evaporates and the starches set, turning the chips snappy. If you pack them into an airtight container while they are still warm, the trapped steam will soften the chips and make them chewy. Leave them on the baking sheet for at least 10 to 15 minutes, then transfer to a wire rack to cool completely if you have the time. Once fully cool, they can sit uncovered for a few hours, or you can store them in a paper-towel-lined container for a few days.
- Make your own everything bagel seasoning to control salt: If you want to reduce sodium or customize the flavor, it takes less than five minutes to make everything bagel seasoning at home. Simply mix together 1 tablespoon white sesame seeds, 1 tablespoon black sesame seeds, 1 teaspoon poppy seeds, 1 teaspoon dried minced garlic, 1 teaspoon dried minced onion, and 1 to 2 teaspoons sea salt, depending on your preference. This DIY blend is more cost-effective and allows you to adjust the ratio of garlic to onion or skip the salt entirely for a lower-sodium version. Store it in an airtight jar at room temperature and it will keep for months. You can also use this homemade blend in other recipes like avocado toast, roasted vegetables, egg salads, or creamy dips.
- Use sweet potatoes that are firm and evenly shaped: The texture and shape of your sweet potatoes affect how uniform your slices will be. Choose sweet potatoes that are thick in the middle and relatively straight, which makes slicing more even and prevents awkward, tiny end pieces. If you have very narrow or tapered sweet potatoes, the end slices will be much thinner and may burn quickly. You can always save those end pieces and roast them separately or chop them into cubes for another dish. Also, remember that sweet potatoes come in different sizes, so adjust the baking time slightly if your slices are larger or thicker than the recipe calls for. The key is to watch the chips in the oven and use visual cues like deep golden edges and a dry surface.
- Double the batch and freeze the extras for later: If you’re already heating up the oven, it costs almost nothing to make a bigger batch. These sweet potato chips freeze surprisingly well if you let them cool completely and then place them in a freezer-safe zip-top bag. They can be frozen for up to 2 months, but be aware that they may lose a little of their crispness after thawing. To re-crisp them, spread them on a baking sheet and warm them in a 300°F (150°C) oven for 5 to 7 minutes. This is a great way to have a healthy snack ready for lunchboxes or after-school cravings without having to slice and bake every week. Just be sure to press out as much air as possible from the bag before sealing to maintain the best texture.
Variations
- Spicy Chili Lime Chips: For a zesty kick, swap the everything bagel seasoning for a mix of 1 teaspoon chili powder, 1/2 teaspoon smoked paprika, 1/2 teaspoon garlic powder, and a pinch of cayenne. After baking, squeeze fresh lime juice over the warm chips and toss with a little lime zest. The citrus brightens the sweetness of the potato and cuts through the heat beautifully. You can also add a sprinkle of Tajín for a tangy, spicy twist that kids and adults alike will love.
- Rosemary Garlic Chips: Elevate your sweet potato chips with a fragrant, savory blend of dried rosemary and garlic. Mix 2 teaspoons finely chopped fresh rosemary (or 1 teaspoon dried) with 1 teaspoon garlic powder and 1 teaspoon onion powder. Toss the sliced sweet potatoes with olive oil and this mixture, then bake as directed. The woodsy aroma of rosemary pairs surprisingly well with the natural earthiness of sweet potatoes, giving the chips a gourmet feel. Serve them alongside sandwiches or use them to top a creamy butternut squash soup for extra crunch.
- Cinnamon-Sugar Sweet Potato Chips: If you have a sweets craving, turn these chips into a paleo-friendly dessert snack. Replace the everything bagel seasoning with a mixture of 1 teaspoon ground cinnamon and 1 tablespoon coconut sugar or maple sugar. Toss the sweet potato slices in coconut oil instead of olive oil, then sprinkle with the cinnamon-sugar blend. Bake at a slightly lower temperature (350°F / 177°C) to prevent the sugar from burning. These sweet chips are like a healthier version of candied sweet potatoes and make a wonderful after-school treat or a crunchy addition to a yogurt parfait.
- Protein-Packed Lunchbox Version: To boost the protein content and make these chips more filling, add a dusting of collagen peptides or unflavored protein powder to the seasoning mix. Simply whisk 1 tablespoon collagen powder together with the everything bagel seasoning before tossing with the sweet potato slices. The collagen melts into the oil and creates a slightly crispier finish while adding about 5 grams of protein per serving. This is an excellent option for parents looking for high-protein snacks for kids that still taste delicious. You can also serve the chips with a side of creamy Greek yogurt dip or guacamole for dipping, turning the snack into a mini lunch that keeps everyone satisfied until dinner.
- Vegan & Whole30 Variation: The base recipe is already vegan and paleo as long as you use olive or avocado oil and a certified paleo everything bagel seasoning. Some store-bought everything bagel seasonings contain sugar or anti-caking agents, so double-check the label if you are strictly paleo or Whole30. You can easily make your own seasoning at home (see tips) to ensure it is compliant. Pair these chips with a fresh vegetable platter, hard-boiled eggs, or a simple avocado salad for a complete and satisfying lunchbox meal. The crunchy, savory chips are so delicious that no one will miss processed potato chips.
- Air Fryer Sweet Potato Chips: If you have an air fryer, you can make these chips even faster and with less oil. Toss the sliced sweet potatoes in just 1 tablespoon of oil and the everything bagel seasoning, then place them in a single layer in your air fryer basket set to 350°F (177°C). Cook for 8 to 12 minutes, shaking the basket halfway through, until crisp and golden. Air fryers tend to make chips extra crunchy because they circulate hot air rapidly. You may need to work in batches depending on the size of your air fryer, but this method is perfect for a quick after-school snack. Just keep an eye on them because you won't be able to flip them individually in the basket.
