Side Dishes
This sweet potato log roll recipe transforms humble sweet potatoes into a showstopping centerpiece with crispy edges and caramelized sweetness. The secret lies in the technique: thinly slicing, layering with spiced butter, and rolling tightly before baking until golden.
I developed this method after years of testing—it’s the perfect balance of tender interior and crispy exterior that keeps everyone asking for seconds.
The process starts with roasting whole sweet potatoes until tender, then slicing them into even layers for maximum crispiness. Between each layer, I brush on a mixture of melted butter, cinnamon, and brown sugar, creating a caramelized crust that’s impossible to resist.
For extra flair, I top the log with a celery crown (just a few celery stalks arranged around the top), which adds a decorative touch that’s as functional as it is beautiful.
What makes this dish truly special is how versatile it is—serve it as a holiday centerpiece, a Thanksgiving side, or even a dessert when you add a dollop of whipped cream and a sprinkle of cinnamon.
The aroma alone will fill your kitchen with warmth, and the first bite delivers that perfect contrast of soft, spiced sweet potato with a crispy exterior that’s worth the effort.
Ready in about 50 minutes with minimal hands-on time, this recipe is ideal for gatherings or when you want to impress without spending hours in the kitchen. The key is patience—letting the sweet potatoes roast until fork-tender before slicing ensures they hold together beautifully when rolled.
Once baked, the log becomes a golden, fragrant masterpiece that’s as delicious as it is stunning.

The sweet potatoes are everything here. Look for organic at Whole Foods or Trader Joe's—they hold their shape better when sliced. If you can't find organic, regular sweet potatoes work too, just peel them first (the skin can get tough when roasted). The key is using large, evenly shaped ones so they slice into consistent layers. I always buy a few extra—you'll want them fork-tender when roasted, and sometimes a couple get overcooked in the process. For the celery crown, grab the thickest stalks you can find—Costco or local farmers markets have the best ones. And trust me on the organic: the flavor difference is noticeable, especially when caramelized.
No brown sugar? Substitute with dark maple syrup—just reduce the butter by 1 tbsp since it's liquid. Fresh cinnamon is ideal, but if you've only got ground, toast it in a dry pan for 30 seconds first to deepen the flavor. The butter needs to be melted but not hot—just warm enough to coat your fingers when you test it. For the celery crown, if you're feeling fancy, you can make a quick 'glue' with a tiny bit of melted butter to hold the stalks together. And if you're serving this as dessert, swap the brown sugar for maple syrup and add a pinch of nutmeg to the spiced butter.
Roast the sweet potatoes until they're fork-tender but not falling apart—about 45 minutes at 400°F. Let them cool completely before slicing, or the layers will get mushy. The spiced butter mixture keeps for 1 week in the fridge, so make extra if you're prepping ahead. For the celery crown, trim the ends and arrange the stalks in a circle around the log before baking—it's the easiest way to get that perfect rustic look. Once baked, this reheats beautifully. Just wrap it in foil and warm at 350°F for 15 minutes. The crispy edges soften a bit, but it's still delicious.

Step-by-step instructions for sweet potato log roll
Let's create a showstopping dessert with caramelized sweetness and that perfect crispy exterior.
Prepare the Sweet Potatoes for Roasting
Preheat your oven to 400°F and line a baking sheet with parchment paper. Using a sharp knife, carefully slice the 2 whole large sweet potatoes lengthwise into ¼-inch thick slices. I aim for even slices—this ensures they cook uniformly and create the perfect spiral when rolled.
Arrange the slices in a single layer on the prepared baking sheet, leaving ½ inch between each slice. Brush both sides of each slice with a thin layer of the melted unsalted butter using a pastry brush. This butter will create a golden crust and add richness to the finished log roll.
Bake for 15 minutes until the edges begin to soften slightly and the butter starts to caramelize. You'll know they're ready when the edges look slightly translucent. Remove from the oven and let them cool for 5 minutes—this prevents the slices from sticking together when you stack them.
Create the Spiced Butter Layer
While the sweet potatoes cool, combine the 0.5 cup unsalted butter (once it's cooled slightly from melting), 0.25 cup light brown sugar, 1 tablespoon ground cinnamon, and 0.5 teaspoon sea salt in a small bowl. Mix until the sugar and spices are evenly distributed throughout the butter.
This spiced butter mixture is what transforms a simple roasted sweet potato into something extraordinary. The cinnamon and salt enhance the natural sweetness while adding depth of flavor. Spread a thin layer of this mixture over each of the cooled sweet potato slices using the back of a spoon—about ½ teaspoon per slice.
Assemble and Roll the Log
Now for the fun part—rolling! Place one sweet potato slice on a clean work surface and sprinkle lightly with the 1 tablespoon all-purpose flour. This helps prevent sticking when you roll. Add another slice on top, brushing the bottom slice with a tiny bit of whole milk to help with adhesion.
Continue layering the slices, brushing each with milk and adding a bit more spiced butter between layers. As you build, you'll notice the layers start to stick together. Once you've used all the slices, carefully roll the stack into a tight log shape, sealing the edges as you go. This creates that classic spiral effect that makes this dessert so impressive.
Bake Until Golden and Crispy
Return the assembled log to the baking sheet and brush the outside generously with the remaining spiced butter mixture. Sprinkle the top with the 1 tablespoon granulated sugar and bake at 375°F for 25-30 minutes until the outside is deep golden brown and crispy to the touch.
Here's where the magic happens—the sugar caramelizes, creating that beautiful glossy crust while keeping the inside tender. The log should feel firm when you press it gently, but not rock-hard. If it browns too quickly, tent it loosely with foil for the last 10 minutes of baking.
Add the Celery Crown and Serve
While the log is still warm, prepare the celery crown by cutting the 4 whole fresh celery stalks diagonally into ½-inch pieces. Arrange them in a circular pattern on top of the log, pressing them gently into the warm butter to help them stick.
Let the log cool for 10 minutes before slicing into 6 equal wedges. Serve warm with a dollop of heavy whipping cream on the side if desired. The contrast between the crispy exterior, tender interior, and fresh cream makes this dessert truly special.
Pro Tips For Making Sweet Potato Log Roll
- Slice Evenly, Stack Tightly: I learned this the hard way—uneven slices mean a wonky roll that unravels when you slice it later. Cut the sweet potatoes into thin (about ¼-inch) even slices on a mandoline or sharp knife, then stack them like a Jenga tower before rolling. The tighter the fit, the cleaner the final spiral.
- Boil Until Fork-Tender: Sweet potatoes should be soft enough to pierce with a fork but not falling apart—think "just done" when you test them. Overcooking turns them mushy; undercooking leaves you with a chewy center. Drop them in boiling water for 12–15 minutes (depending on size), then shock in ice water to stop cooking.
- Salt the Butter Early: Don’t wait until the end to season—mix the sea salt (about ½ teaspoon per ¼ cup butter) into the softened butter before spreading it on the slices. The salt dissolves into the butter as it melts, ensuring every bite has that balanced sweet-salty flavor. (Yes, even if you’re impatient like me.)
- Skip the Overstuffing: The log roll’s magic is in the layers, not the filling. If you’re tempted to stuff it with nuts or cheese, resist—it’ll make the roll too dense and harder to slice neatly. Stick to the butter-sugar-cinnamon combo; it’s all you need for a caramelized, flavor-packed spiral. (Your future self will thank you.)
Health benefits of this dish
Rich in Vitamin A
Sweet potatoes are nature's vitamin A powerhouses—just one medium potato provides over 400% of your daily needs. This nutrient supports healthy vision, immune function, and cell growth.
The deep orange color comes from beta-carotene, which your body converts to vitamin A. I always choose organic sweet potatoes from Whole Foods for maximum nutrition—they have higher antioxidant levels than conventional varieties. 💪
Complex Carbohydrates
Unlike white potatoes, sweet potatoes offer complex carbohydrates that digest slowly, providing steady energy without blood sugar spikes. The fiber content (about 4 grams per medium potato) keeps you full longer and supports digestive health.
This makes them perfect for balanced meals or satisfying desserts like our log roll. The spiced butter adds flavor without compromising these nutritional benefits.
High in Potassium
With nearly 500mg of potassium per medium potato, sweet potatoes help regulate blood pressure and muscle function. This mineral is often lacking in American diets, making sweet potatoes an excellent natural source.
The roasting process preserves most of the potassium, unlike boiling which can leach nutrients. I've noticed my energy levels stay more stable when I include sweet potatoes in my meals regularly.
Antioxidant Benefits
Sweet potatoes contain anthocyanins (in purple varieties) and carotenoids that combat oxidative stress and inflammation. These antioxidants protect your cells from damage while adding vibrant color to your dishes. The caramelization during baking actually increases some antioxidant levels, making our log roll even healthier.
For extra benefits, I sometimes add a pinch of turmeric to the spiced butter mixture.
Fiber-Rich Dessert
Most desserts are low in fiber, but this sweet potato log roll delivers 6 grams of fiber per serving—about 20% of your daily needs. The fiber helps balance the natural sweetness while supporting gut health.
The celery crown adds even more fiber (about 1 gram per serving) and crunch. This makes it a guilt-free treat that won't leave you with an energy crash afterward. 🌱
Blood Sugar Balance
The combination of fiber, complex carbs, and low glycemic index makes this dessert surprisingly blood-sugar friendly. The cinnamon in our spiced butter actually helps regulate glucose metabolism.
I've had readers with diabetes enjoy this recipe as a special occasion treat—just watch portion sizes since the butter and sugar still add calories. For a lighter version, reduce the brown sugar to 2 tablespoons and use unsweetened applesauce instead of some of the butter.

Frequently asked questions
Can I use regular potatoes instead of sweet potatoes?
Regular potatoes won't work for this recipe—they lack the natural sweetness and vibrant color that makes this dish special. Sweet potatoes have a lower moisture content and higher sugar content, which caramelizes beautifully during baking. If you're set on using regular potatoes, try roasting them first, then layering with a sweet glaze (like honey or maple syrup) and extra spices to mimic the flavor.
How do I keep the log from falling apart when slicing?
First, make sure your sweet potatoes are completely cooled before slicing—warm slices will stick together. Use a sharp knife and cut them into ¼-inch thick slices. The flour dusting between layers and the milk glaze help bind everything together. If your log still feels loose, brush it with extra milk or egg wash before the final bake to add structural support.
What's the best way to reheat leftovers?
Wrap the log roll tightly in foil and reheat at 350°F for 15 minutes. The foil keeps the exterior from drying out while warming the center. For individual slices, pop them in the oven for 5-7 minutes at 375°F. Microwaving works too (30 seconds), but the texture won't be as crispy—best for quick reheats when you're short on time.
Can I make this ahead of time?
Assemble the log up to 24 hours ahead and refrigerate uncovered to prevent sogginess. When ready to bake, add 5-10 minutes to your baking time at 375°F (it'll need extra time to crisp up). For a make-ahead dessert, this is perfect—just bake it fresh before serving to maintain that beautiful golden crust.
What are some creative filling variations?
Try adding a layer of cream cheese and cinnamon between slices for a tangy twist, or stuff with pecans and brown sugar for extra crunch. For a savory version, mix in sautéed mushrooms and herbs before rolling. The possibilities are endless—just keep your fillings moist enough to prevent the log from becoming too dry during baking.
