Ingredients for sweet potato flakes
Crispy flakes need just eight ingredientsâmost you already own. Sweet potatoes and celery shine here.
| Ingredient | Amount | Notes |
|---|---|---|
| Sweet Potatoes đ | 1 ½ lb | Medium-sized, peeled and sliced thin |
| Extra-Virgin Olive Oil đŤ | 2 tbsp | Lightly coats sweet potatoes |
| Sea Salt đ§ | 1 tsp | Kosher or fine grain preferred |
| Celery Stalks 𼏠| 3 whole | Thinly sliced into ribbons |
| Lemon Juice đ | 1 tbsp | Freshly squeezed for brightness |
| Freshly Ground Black Pepper đśď¸ | ½ tsp | Enhances celery topping flavor |
| Hummus đĽ | ½ cup | For serving (optional) |
| Avocado Oil đŤ | 1 tbsp | High smoke point for baking |
Sweet potatoes are the starâpick firm, vibrant ones with no soft spots. Trader Joe's and Whole Foods carry the best organic varieties, but any medium-sized orange sweet potatoes work. Peel them first (the skin can burn), then slice them as thinly as possibleâa mandoline makes this easier. If you donât have one, stack slices and carefully shave them with a sharp knife. The thinner the slices, the crispier the flakes. Store peeled potatoes in cold water until ready to use to prevent browning.
No mandoline? Use a sharp chefâs knife and take your timeâpatience pays off here. For the celery, look for crisp stalks with no brown spots. The ribbons should be about 1/8-inch wide for perfect texture. Swap olive oil for avocado oil if you want extra crispiness (higher smoke point). No lemon juice? Lime juice works too. And if youâre short on time, pre-cut sweet potatoes from the storeâs salad bar section will save you slicing workâjust rinse and pat dry before seasoning.
These flakes stay crispy for 3 days in an airtight container, but honestly, theyâre best fresh. Store the celery ribbons separately if youâre prepping ahead. Freeze the flakes for up to 1 monthâtheyâll lose some crunch but still taste amazing when reheated. I like keeping a batch on hand for quick salads or snacking. The hummus pairing? Store-bought or homemadeâjust grab whateverâs in your fridge.

Step-by-step instructions for crispy celery-topped sweet potato flakes
Here's how to transform humble sweet potatoes into addictive, crispy flakes with that perfect celery crunch.
đĽ Step 1: Prep and Slice the Sweet Potatoes
Begin by peeling the 1.5 lb sweet potatoes and cutting them into â -inch thick slices using a sharp mandoline or chef's knife. I like to work in batchesâthis keeps the slices uniform and prevents the knife from getting dull. Arrange the slices on a clean kitchen towel to blot away any excess moisture, which is crucial for crispiness.
Here's the thingâdon't skip the drying step. Even slightly damp slices won't crisp properly. After blotting, let them air-dry on a wire rack for 10 minutes. You'll know they're ready when they look matte, not glossy. This prep work makes all the difference in achieving that perfect crunch.
đł Step 2: Season and Roast to Crispy Perfection
Preheat your oven to 425°F and line two baking sheets with parchment paper. Arrange the dried sweet potato slices in a single layer, leaving ½-inch between each pieceâthey'll expand as they cook. Drizzle evenly with the 2 tbsp extra-virgin olive oil and sprinkle with 1 tsp sea salt and ½ tsp freshly ground black pepper, tossing gently to coat.
Roast for 20-25 minutes, flipping halfway through, until the edges are deep golden brown and the centers are tender when pierced with a fork. Watch closely in the last 5 minutesâyou want crispy flakes, not burnt edges. The high heat and avocado oil's stability are key here for that perfect texture.
đ¨âđł Step 3: Prepare the Celery Topping
While the sweet potatoes roast, slice the 3 whole celery stalks into thin ribbons using a sharp knife or mandoline. Toss them in a bowl with 1 tbsp lemon juice and let them sit for 5 minutes to soften slightly. This brightens their flavor and prevents them from overpowering the sweet potatoes.
Here's where it gets funâtaste the celery mixture. If it needs more zing, add a pinch of salt or a tiny splash of lemon juice. The topping should be vibrant and fresh, not bland. This is your chance to adjust before assembly, so don't rush it.
đĽ Step 4: Assemble and Serve Warm
Transfer the crispy sweet potato flakes to a serving platter. Spoon the ½ cup hummus around the edges, then arrange the celery ribbons in an overlapping pattern over the flakes. The contrast of creamy hummus, crispy sweet potatoes, and fresh celery is what makes this dish special.
Serve immediately while everything is warm and crispy. The sweet potatoes should hold their flake shape with just a hint of softness in the center, and the celery should add that satisfying crunch with every bite. If you're feeling fancy, garnish with a sprinkle of flaky sea salt or a drizzle of olive oil.
Pro Tips For Making Sweet Potato Flakes
- Peel and Dry First: Sweet potatoes hold moisture like a spongeâslice them, then toss with a pinch of salt and let sit for 10 minutes on a towel. This prevents a soggy, gummy mess when you roast them later, and the salt draws out extra water so they crisp properly.
- Use a Mandoline for Even Slices: I tried hand-slicing once and ended up with uneven flakes that cooked at different rates. A mandoline set to 1/8-inch thickness guarantees consistent thicknessâno undercooked centers or over-charred edges. Just remember to work slowly and keep your fingers clear.
- Roast in Two Batches: Crowding the pan turns your crispy flakes into a sad, limp pile. Spread them in a single layer with space between each piece, and if your tray is full, roast half first. Trust me, the extra 5 minutes waiting for the second batch is worth the perfect texture.
- SautĂŠ Celery First: Celery adds depth, but if you toss it in raw, itâll just sit there like a wet log. SautĂŠ it in olive oil until it softens and releases its flavorâabout 3-4 minutesâbefore adding the flakes. This makes the lemon and salt actually stick to the celery instead of just floating around.
Health benefits of this dish
Vitamin A Powerhouse
Sweet potatoes are one of nature's richest sources of vitamin A, with just ½ cup of flakes providing over 400% of your daily needs. This nutrient supports vision health, immune function, and skin regeneration.
The flaking process preserves most of the vitamin A compared to traditional baking or mashing methods. đ
Fiber-Rich Crunch
Each serving of these crispy flakes delivers 5 grams of dietary fiberâabout 20% of your daily requirement. This soluble fiber helps regulate digestion and keeps you feeling full longer, making these perfect for snacking or adding to salads. The celery topping adds another 2 grams of fiber, boosting the nutritional punch while keeping the texture satisfyingly crisp.
Natural Sweetness
Unlike processed snacks, these flakes get their sweetness from natural sugars in sweet potatoes, with no added refined sugars. The low glycemic index of sweet potatoes means you get energy without the blood sugar spike.
The celery topping's natural bitterness balances the sweetness, creating a harmonious flavor profile that's both delicious and blood-sugar-friendly.
Antioxidant Boost
Sweet potatoes contain beta-carotene, lutein, and zeaxanthin, powerful antioxidants that combat oxidative stress. The flaking process concentrates these nutrients in every crispy bite. The celery adds apigenin, another antioxidant that supports heart health.
Together, they create a snack that's as good for you as it is for your taste buds.

At just 120 calories per serving, these flakes offer satisfying crunch without the calorie overload. The high fiber content means you get volume and texture without excess calories. This makes them ideal for weight management or as a guilt-free snack option that still feels indulgent.
Blood Sugar Balance
The combination of fiber and complex carbs in sweet potatoes helps stabilize blood sugar levels. The celery's natural diuretic properties further support metabolic health. This makes these flakes a smart choice for anyone monitoring blood sugar or following a balanced diet.
The crispy texture also satisfies cravings for something crunchy without the refined carb backlash.

Frequently asked questions
Can I make these sweet potato flakes without a mandoline?
A sharp chef's knife works perfectly. Cut the sweet potatoes into â -inch thick slices by placing them on a cutting board, holding the knife at a slight angle, and carefully slicing through in one motion. Work in batches to keep your knife sharpâdull blades create uneven slices that won't crisp properly. For extra thin slices, stack a few potatoes together and slice through the pile.
How do I store leftover sweet potato flakes?
Keep them crispy for 3 days in an airtight container at room temperature. For longer storage, freeze the flakes for up to 1 monthâthey'll lose some crunch but still taste great when reheated in a 350°F oven for 5-10 minutes. Store the celery topping separately if prepping ahead, as it softens faster. Reheat flakes alone for 10 seconds in the microwave if you prefer extra crunch.
Can I use regular potatoes instead of sweet potatoes?
Not recommended! Sweet potatoes have a naturally sweet flavor and lower moisture content that creates the perfect crispy texture. Regular potatoes will turn out soggy and lack the sweetness. If you're allergic to sweet potatoes, try purple sweet potatoes for a similar texture with a different color twist. The flaking technique works best with starchy root vegetables like yams or regular potatoes, but they won't match the flavor or nutritional benefits.
What other toppings work well with these flakes?
Endless possibilities! Try toasted pumpkin seeds for crunch, avocado slices for creaminess, or smoked paprika for a spicy kick. For extra protein, sprinkle with crumbled feta or chickpeas. The key is balancing texturesâpair crispy flakes with something soft (like hummus) or chewy (like dried fruit). The celery topping can also be swapped for thinly sliced radishes or shredded cabbage for different flavor profiles.
Why did my flakes turn out soggy?
This usually happens from excess moisture or undercooking. First, ensure you thoroughly dried the slices after slicingâpat them with a towel and let them air-dry for 10 minutes. Second, don't overcrowd the baking sheet (leave ½-inch between slices). Finally, bake at 425°F until edges are golden brown and centers are tender when piercedâ20-25 minutes should do it. If they're still damp, spread them on a wire rack for 5 minutes after baking to crisp up.
