Side Dishes
This baked sweet potato rounds recipe transforms humble sweet potatoes into crispy, golden bites that disappear faster than you can say "appetizer." The secret lies in the celery crust—a clever way to add texture and subtle crunch without overpowering the natural sweetness.
I developed this technique after years of experimenting with ways to make sweet potatoes more exciting than just mashed or roasted, and it never fails to impress.
The beauty of these rounds is their versatility—they work as a snack, appetizer, or side dish, depending on how you serve them. Baked at 425°F for just 20 minutes, they develop a crispy exterior while staying tender inside.
The celery crust adds a refreshing, slightly salty contrast that balances the natural sweetness perfectly, making them addictive in a single bite.
What you’ll end up with is a tray of golden, crispy rounds that look as appealing as they taste—ideal for game day, holiday appetizers, or a simple weeknight snack. The celery crust holds its shape, ensuring every bite delivers that satisfying crunch.
Serve them warm with a drizzle of garlic butter or a side of chili-lime dip for extra flavor.
These rounds are also a great way to use up whole sweet potatoes without wasting anything. The recipe scales easily, so you can make a single batch for a snack or double it for a crowd. Here’s how to achieve that perfect crispy texture every time.
Ingredients for baked sweet potato rounds
Just eight ingredients transform simple sweet potatoes into crispy, addictive bites everyone will love.
| Ingredient | Amount | Notes |
|---|---|---|
| Large Sweet Potatoes 🍠 | 2 whole | Medium-sized, peeled and sliced |
| Celery Stalks 🧅 | 1 cup | Finely chopped for crust |
| All-Purpose Flour 🌾 | ½ cup | For binding crust |
| Shredded Parmesan Cheese 🧀 | ¼ cup | Freshly grated preferred |
| Large Eggs 🥚 | 1 whole | Beaten for coating |
| Olive Oil 🫒 | 2 tbsp | For drizzling |
| Salt 🧂 | ½ tsp | Kosher or sea salt |
| Ground Black Pepper 🌶️ | ¼ tsp | Freshly ground |
| Garlic Powder 🧄 | ½ tsp | For extra flavor |
| Paprika 🌶️ | ½ tsp | Smoked for color |
| Butter 🧈 | 2 tbsp | Melted for drizzling |
| Fresh Parsley 🌿 | ¼ cup | Chopped for garnish |
The sweet potatoes are the star, so grab firm, medium-sized ones—they hold their shape better than small ones. Trader Joe's and Whole Foods carry the best variety, but any grocery store will work. Peeled and sliced into even rounds (about 1/4-inch thick), they cook perfectly in 20 minutes. Pro tip: use a mandoline for even slices if you're feeling fancy—no judgment if you eyeball it though. The celery crust is what makes these rounds special; fresh celery (not the wilted kind) gives that perfect crunch and subtle saltiness that balances the sweetness.
No celery? Finely chopped green onions or scallions work in a pinch, but you'll lose that signature celery flavor. Short on Parmesan? Nutritional yeast or extra flour can help bind the crust, though it won't taste the same. The egg is non-negotiable—it's what helps the crust stick, so don't skip it. If you're watching cholesterol, flax eggs (1 tbsp ground flax + 3 tbsp water) work too. The paprika adds that gorgeous golden color, so don't skip it—smoked gives a deeper flavor, but regular works fine. And yes, you can use pre-shredded cheese, but freshly grated melts better and tastes richer.
These rounds reheat beautifully—just pop them in the oven at 350°F for 5-10 minutes to restore that crispy texture. Store leftovers in an airtight container in the fridge for up to 3 days, or freeze for 2 months (they thaw in 15 minutes at room temp). I always make a double batch because they disappear fast—perfect for game day, holiday appetizers, or a quick snack. Serve warm with a drizzle of melted butter and extra parsley for that restaurant-quality touch.

Step-by-step instructions for crispy celery-crusted sweet potato rounds
Here's how to transform simple sweet potatoes into golden, crispy rounds that'll impress everyone.
Prepare the Sweet Potatoes for Even Cooking
Preheat your oven to 425°F for maximum crispiness. Peel the 2 whole large sweet potatoes and slice them into ½-inch thick rounds using a sharp chef's knife. I find a mandoline works best for even slices, but a steady hand with a regular knife works too.
Arrange the sweet potato rounds in a single layer on a parchment-lined baking sheet, spacing them about ½ inch apart. This gives them room to crisp up rather than steam. Brush each round lightly with 1 tablespoon of the olive oil, just enough to coat the surface evenly. The oil helps create that perfect golden crust.
Create the Crispy Celery Crust Mixture
In a medium bowl, combine the 1 cup finely chopped celery stalks, ½ cup all-purpose flour, ¼ cup shredded parmesan cheese, ½ teaspoon salt, ¼ teaspoon ground black pepper, ½ teaspoon garlic powder, and ½ teaspoon paprika. Mix everything together with your hands or a fork until evenly distributed.
This mixture is what creates that addictive crunchy texture. The celery adds freshness while the flour and cheese bind everything together. I like to press the mixture gently between my fingers to make sure all the spices are evenly coated in the flour.
Coat and Bake for Maximum Crispiness
Beat the 1 whole large egg in a separate shallow bowl. Dip each sweet potato round into the egg, letting any excess drip off, then press it firmly into the celery crust mixture. You'll want to coat both sides thoroughly but not so thick that it falls off when you handle them.
Place the coated sweet potato rounds back on the baking sheet, making sure they're still spaced apart. Drizzle with the remaining 1 tablespoon olive oil and the 2 tablespoons melted butter, spreading it evenly over the tops. Bake for 18-20 minutes until the crust is deep golden brown and the edges are crispy.
Finish with Fresh Parsley and Serve Immediately
Remove the sweet potato rounds from the oven and sprinkle with the ¼ cup chopped fresh parsley. The parsley adds a fresh pop of color and flavor that balances the richness of the crust. Serve them immediately while they're still piping hot and crispy.
Each bite should deliver that perfect combination of tender sweet potato and crunchy celery crust. If you want to keep them warm, transfer them to a wire rack set over a baking sheet to prevent sogginess. These make an excellent side dish or even a hearty appetizer when served with a dollop of sour cream or Greek yogurt.
Pro Tips For Making Baked Sweet Potato Rounds
- PREHEAT PAN TO 425°F: I learned this the hard way—starting at 375°F just to save 5 minutes means your rounds steam instead of crisp. That extra 50°F guarantees a golden crust on the bottom while the centers stay tender. Yes, even if you're impatient like me.
- GRATE CELERY FINE: Sounds weird, but it works: pulse celery in a food processor for 3-4 seconds until it’s almost paste-like. This keeps the rounds from turning soggy when baking—no one wants a mushy sweet potato casserole. (Your future self will thank you.)
- DON’T OVERMIX THE BATTER: After burning three batches, I finally figured out that folding the shredded sweet potatoes and Parmesan in just until combined prevents a dense, gummy texture. Overmixing activates the gluten in the flour, and suddenly you’ve got a chewy brick instead of tender rounds.
- USE COLD EGGS: This isn’t the prettiest method, but it’s the tastiest: whisk the eggs cold straight from the fridge, then let the mixture sit for 5 minutes before baking. The cold eggs create tiny air pockets that make the rounds lighter—no one notices the effort, but they’ll notice the difference.
Creative variations of this recipe
Sweet & Spicy Glaze Twist
Swap the celery crust for a honey-chili glaze by mixing 2 tbsp honey, 1 tbsp chili powder, 1 tsp lime juice, and ½ tsp smoked paprika.
Brush this over the sweet potato rounds after baking for a caramelized, spicy-sweet finish. I love this version for game day—it’s finger-licking good! 🌶️
Cinnamon-Sugar Baked Donut Style
After baking, toss the warm rounds in a mix of 2 tbsp melted butter, 3 tbsp brown sugar, and 1 tsp cinnamon. Return them to the oven for 2-3 minutes at 350°F to caramelize the sugar. These taste like sweet potato donuts—perfect for breakfast or dessert! 🍩
Loaded Nacho Toppings
Turn these into nacho bites by topping baked rounds with ¼ cup shredded cheddar, 2 tbsp black beans, 2 tbsp salsa, and 2 tbsp Greek yogurt (instead of sour cream). Broil for 1-2 minutes to melt the cheese. A fun, handheld twist on nachos! 🧀
Herbed Garlic Butter Dip
Serve with a quick dip: melt 4 tbsp butter, mix with 1 minced garlic clove, 1 tbsp chopped parsley, and a pinch of salt. Drizzle over the rounds or serve on the side. This adds a rich, savory contrast to the sweet potatoes. 🧈
Vegan Celery Crust
For a plant-based version, replace the egg with 2 tbsp aquafaba (chickpea brine) and use ¼ cup nutritional yeast instead of Parmesan. The crust still sticks perfectly, and it’s just as crispy! Great for vegan gatherings. 🌱
Breakfast Hash Twist
Add ½ cup diced breakfast sausage (or vegan crumbles) and ¼ cup diced bell peppers to the crust mixture. Bake as directed, then top with a fried egg for a hearty breakfast hash. This makes brunch a breeze! 🍳

Frequently asked questions
Why does the recipe call for peeling the sweet potatoes?
The peel can be tough and bitter when baked, especially in thin rounds. Peeling ensures a smooth texture and even cooking. If you prefer to keep the skin (for fiber and nutrients), slice them slightly thicker—about ½-inch—and bake for 22-25 minutes to fully cook through. The peel adds rustic charm but may not crisp as nicely.
Can I make these rounds ahead of time?
Bake them fresh for best texture, but you can prep the crust mixture and store it in an airtight container for up to 2 days. For leftovers, reheat at 350°F for 5-10 minutes to restore crispiness. Freeze unbaked rounds (coated in crust) for 2 months—bake straight from frozen, adding 5-7 extra minutes. Just don’t freeze them after baking, or they’ll get soggy.
What if my crust falls off when baking?
This usually happens if the egg coating isn’t dry enough or the crust isn’t pressed firmly. Let the egg-dipped rounds sit for 2-3 minutes before pressing into the crust to help it adhere. For extra stickiness, add 1 tbsp cornstarch to the crust mixture. If it still falls off, reduce baking time by 2 minutes—overbaking dries out the egg and makes the crust brittle.
Are these rounds kid-friendly?
Yes! The celery crust adds a mild, fresh flavor that most kids enjoy, especially if you cut them into smaller, bite-sized pieces. For picky eaters, skip the celery and use ½ cup crushed cornflakes or panko breadcrumbs instead—they’ll still be crispy and sweet. Serve with a side of ketchup or yogurt dip to make them even more appealing.
How do I adjust the recipe for a crowd?
Double the ingredients and use two baking sheets for even cooking. For 8 servings, you’ll need 4 whole sweet potatoes, 2 cups celery, and 1 cup flour. Bake in batches, rotating the pans halfway for even browning. To save time, use a food processor to finely chop the celery and mix the crust ingredients. Prep all components ahead, then assemble and bake as needed.
