Ingredients for sweet potato strings
Nine simple ingredients transform humble sweet potatoes into crispy, celery-topped bites.
| Ingredient | Amount | Notes |
|---|---|---|
| Large Sweet Potatoes 🍠 | 2 whole | Medium-sized, organic preferred |
| Extra-Virgin Olive Oil 🫒 | 2 tbsp | Light coating for crispiness |
| Kosher Salt 🧂 | 1 tsp | Fine grain preferred |
| Ground Black Pepper 🌶️ | ½ tsp | Freshly ground for best flavor |
| Smoked Paprika 🌶️ | ½ tsp | For nutty warmth |
| Garlic Powder 🧄 | ½ tsp | Or fresh garlic, minced |
| Celery Stalks 🧅 | 2 whole | Fresh, crisp variety |
| Unsalted Butter 🧈 | 2 tbsp | For celery topping |
| Fresh Parsley 🌿 | ¼ cup | Chopped, for garnish |
| Lemon Zest 🍋 | 1 tsp | Brightens the flavor |
| Sesame Seeds 🌾 | 1 tbsp | Optional, for crunch |
Sweet potatoes are the star here—look for ones that are firm and smooth-skinned at Whole Foods or your local market. The orange-fleshed varieties work best for that classic sweetness. If you can't find organic, regular sweet potatoes work fine, just scrub them well. For the celery, crisp stalks are key—avoid the wilted ones, and if they're a bit dry, soak them in cold water for 10 minutes before using. I always grab extra parsley because it adds that fresh pop at the end, and it's one of those herbs that lasts forever in the fridge if you wrap it in damp paper towels.
No smoked paprika? Regular paprika plus a pinch of cayenne works in a pinch. Want to skip the butter on the celery topping? Olive oil or vegan butter keeps it just as flavorful. The sesame seeds are totally optional but add that satisfying crunch—if you're out, toasted pumpkin seeds are a great swap. For the celery, if you can't find fresh, dried celery flakes (about 1 tbsp) will give you a similar flavor, though it won't have that same satisfying crunch. And if you're feeling fancy, a sprinkle of toasted coconut flakes adds a sweet contrast.
These crisp up best when made fresh, but you can prep the sweet potato strings ahead and store them in the fridge for 2 days before cooking. Once cooked, they're at their best served immediately, but if you need to reheat, 30 seconds in the air fryer at 375°F brings back that crunch. The celery topping keeps for 3 days in the fridge if stored in an airtight container. I like to double the batch and freeze half—just thaw overnight in the fridge before serving.

Step-by-step instructions for sweet potato strings
Here's how to transform sweet potatoes into crispy, celery-topped bites with perfect texture every time.
Prep and Roast the Sweet Potatoes
Preheat your oven to 425°F and line two baking sheets with parchment paper. Peel the 2 whole large sweet potatoes and cut them into ¼-inch thick sticks using a mandoline or sharp knife. The thinner the sticks, the crispier they'll get.
Toss the sweet potato sticks with 2 tablespoons extra-virgin olive oil, 1 teaspoon kosher salt, and ½ teaspoon smoked paprika until evenly coated. Spread them in a single layer on the prepared baking sheets—don't crowd them or they won't crisp properly. Roast for 20-25 minutes, flipping halfway through, until they're golden brown and tender when pierced with a fork.
Season the Celery Topping
While the sweet potatoes roast, prepare the celery topping by melting 2 tablespoons unsalted butter in a small skillet over medium heat. Add the 2 whole celery stalks, sliced into ¼-inch thick rounds, and cook for 3-4 minutes until just tender and lightly golden.
Remove from heat and stir in ½ teaspoon garlic powder, ½ teaspoon ground black pepper, and 1 teaspoon lemon zest. Let it cool slightly while you finish the sweet potatoes. The celery should be tender but still hold its shape—overcooking makes it mushy, which ruins the texture contrast.
Assemble and Garnish
Once the sweet potato strings are done roasting, transfer them to a large serving bowl. Add the seasoned celery mixture and toss gently to combine. The heat from the sweet potatoes will warm the celery through while keeping it crisp.
Sprinkle with ¼ cup chopped fresh parsley and 1 tablespoon sesame seeds for color and crunch. Toss lightly again to distribute evenly. These bites are best served immediately while the sweet potatoes are still crispy—wait too long and they'll soften.
Serve with Dipping Sauce (Optional)
For extra flavor, serve with a simple dipping sauce made by whisking 2 tablespoons plain yogurt (not listed in ingredients) with ½ teaspoon lemon zest and a pinch of salt. The cool yogurt balances the warm, nutty sweet potatoes beautifully.
Divide the sweet potato strings among 4 servings, garnishing each portion with an extra sprinkle of sesame seeds. These crispy, celery-topped bites make a fantastic appetizer, side dish, or even a light main course when paired with a fresh salad or grilled protein.
Pro Tips For Making Sweet Potato Strings
- BOIL ‘EM UNTIL SOFT: Sweet potatoes should pierce with a fork like butter—no resistance. I used to pull them out too soon, and the strings would fall apart when cutting. Boil them 20-25 minutes (depending on size) until a knife slides in effortlessly. Cold water speeds this up; don’t rush the heat.
- CUT WHEN COOL: Slice those potatoes when they’ve cooled just enough to handle—still warm, but not scorching. I learned this after burning my fingers twice. A damp towel helps grip them, and the strings hold shape better when you’re not wrestling with a slippery, hot potato.
- SALT THE OIL: Toss the strings in olive oil and a pinch of salt before roasting. The salt clings to the fibers, amplifying flavor as they crisp. I skipped this once and ended up with bland, greasy strings—don’t make that mistake.
- REST BEFORE ROASTING: Let the cut strings sit in a colander for 5 minutes after boiling. This evens out moisture, so they crisp instead of steaming. I was skeptical until I tried it—now my strings are golden and crispy, not soggy. (Yes, even if you’re impatient like me.)
Health benefits of sweet potato strings
Fiber-Rich Side Dish
Sweet potato strings are an excellent source of dietary fiber, with about 5 grams per serving—that’s 20% of your daily needs! Fiber supports digestive health, keeps you feeling full longer, and helps regulate blood sugar levels.
The crispy texture makes them satisfying while delivering plant-based nutrition without heavy calories. 💪
Vitamin A Powerhouse
Sweet potatoes are one of the best natural sources of vitamin A, with 150% of your daily value per serving. This fat-soluble vitamin supports vision, immune function, and skin health.
The vibrant orange color comes from beta-carotene, which your body converts into vitamin A. I always notice my skin feels brighter after eating them regularly!
Blood Sugar Balance
Despite their natural sweetness, sweet potatoes have a low glycemic index when prepared this way. The fiber and healthy fats from olive oil help slow sugar absorption, making these strings a smart choice for blood sugar management.
Pair them with protein (like grilled chicken) to further stabilize energy levels throughout the day.
Antioxidant Boost
The celery topping adds vitamin K and flavonoids, while sweet potatoes provide anthocyanins (especially in purple varieties). These antioxidants combat cellular damage and reduce inflammation. The combination creates a nutrient-packed dish that’s as good for you as it tastes!
Gluten-Free & Vegan
This recipe is naturally gluten-free and easily made vegan by omitting butter (use olive oil). The celery topping remains flavorful without dairy, and the sweet potatoes provide plant-based energy without animal products. It’s perfect for anyone following allergy-friendly or plant-based diets.

Nutrition facts
Frequently asked questions
Can I make sweet potato strings without a mandoline?
A sharp chef's knife works perfectly—just cut the sweet potatoes into ¼-inch thick sticks. For extra precision, freeze the sweet potatoes for 15 minutes first to firm them up. The key is consistency in thickness so they cook evenly and get that perfect crispy texture.
How do I store leftover sweet potato strings?
Store cooked strings in an airtight container in the fridge for up to 3 days. For best texture, reheat in an air fryer at 375°F for 30 seconds or microwave for 10 seconds—just enough to warm through without losing crispiness. The celery topping keeps separately for 3 days in the fridge.
Can I use regular potatoes instead of sweet potatoes?
While possible, sweet potatoes give the best flavor and texture. Regular potatoes will be less sweet and more starchy, resulting in a different taste profile. For a similar texture, try purple sweet potatoes—they add beautiful color and extra antioxidants! The recipe is designed specifically for sweet potatoes to achieve that perfect balance of sweetness and crunch.
What's the best way to make them extra crispy?
For maximum crispiness, pat the sweet potato sticks completely dry with a paper towel before seasoning. Use a high-heat method like air frying at 400°F for 12-15 minutes or baking at 425°F for 20-25 minutes with no crowding on the pan. A light coating of oil is essential—don't skip this step!
Are these strings safe for kids?
Yes, but with some adjustments! Cut them into smaller pieces to prevent choking hazards. For picky eaters, try a mild version with just salt and a tiny bit of butter on the celery. The natural sweetness is usually a hit, but always check for any nut allergies if using sesame seeds. Serve with a familiar dip like ranch to make them more appealing.
