Ingredients for sweet potato log roll
Six ingredients transform simple sweet potatoes into a showstopping holiday centerpiece.
| Ingredient | Amount | Notes |
|---|---|---|
| Large Sweet Potatoes 🍠 | 3 whole | Organic preferred, uniform size |
| Unsalted Butter 🧈 | ½ cup | Cold, cut into small cubes |
| Ground Cinnamon 🌿 | 2 tbsp | Freshly ground for warmth |
| Granulated Sugar 🍚 | ¼ cup | Light brown preferred |
| Large Egg 🥚 | 1 whole | Room temperature for binding |
| All-Purpose Flour 🌾 | ½ cup | For lattice topping |
| Salt 🧂 | ½ tsp | Diamond Crystal preferred |
| Ground Nutmeg 🌿 | ¼ tsp | Freshly grated for depth |
| Pure Maple Syrup 🍯 | 2 tbsp | Grade B for richer flavor |
| Fresh Thyme Leaves 🌿 | ¼ cup | Chopped, for lattice |
| Heavy Cream 🥛 | ¼ cup | Whipped for filling option |
| Garlic Powder 🧄 | ¼ tsp | For savory variation |
The sweet potatoes are the foundation—uniform size and organic quality matter most. Whole Foods or local farmers markets have the best selection for this recipe. Look for potatoes that are firm, heavy for their size, and free of soft spots. If you can't find organic, conventional works fine—just scrub them thoroughly. The cold butter cubes create pockets of richness that melt perfectly during baking. For the cinnamon, Penzeys Spices has the best ground variety, but any fresh-ground spice will do. The secret to even slices? Use a mandoline or sharp chef's knife—thin, even rounds are key for that bakery-style roll.
No maple syrup? Honey or agave nectar works in a pinch (though maple's depth is ideal). Want a savory version? Swap the cinnamon for garlic powder, onion powder, and smoked paprika—then fill with herbed cream cheese or caramelized onions. The lattice topping is non-negotiable for that crispy texture, but if you're nervous about the design, cut straight strips instead. For the egg, room temperature ensures better binding—just microwave it for 20 seconds if it's straight from the fridge. The thyme leaves add a subtle floral note that pairs beautifully with the sweet potatoes, but dried thyme at half the amount works if you're in a hurry.
Store any leftovers in an airtight container for 3-4 days—though this disappears so fast, you'll likely reheat just a few slices. For make-ahead convenience, assemble the log roll up to 24 hours ahead and refrigerate. Bring to room temperature before baking. The filling can be prepped a day ahead too—just keep it chilled until ready to roll. Slice into wedges before serving for that restaurant-worthy presentation. The lattice stays crispy for about 1 hour after baking, so serve immediately if you're hosting. For freezing, slice the baked log roll and freeze portions on a tray before transferring to a bag—3 months max for best texture.

Step-by-step instructions for sweet potato log roll
The secret to perfect sweet potato log rolls lies in precision roasting and lattice technique. Here's how to achieve that signature crispy exterior and tender interior.
Prepare and Roast the Sweet Potatoes
Preheat your oven to 425°F and line a baking sheet with parchment paper. Pierce each of the 3 whole large sweet potatoes with a fork in several places to allow steam to escape during roasting. This prevents them from bursting and ensures even cooking.
Place the sweet potatoes on the prepared baking sheet and roast for 45-50 minutes until they're fork-tender with a slightly caramelized exterior. You'll know they're done when the skin is tender and the flesh gives slightly when pressed with a fork. Let them cool for 10 minutes before handling - this makes the next steps much easier.
Create the Spiced Filling Mixture
While the sweet potatoes roast, prepare the spiced filling by combining the 0.5 cup unsalted butter (cold cubes), 0.25 cup granulated sugar, 2 tbsp ground cinnamon, 0.25 tsp ground nutmeg, and 0.5 tsp salt in a mixing bowl. Use a pastry cutter or your fingers to work the butter into the dry ingredients until it resembles coarse crumbs with pea-sized butter pieces remaining.
In a separate bowl, whisk together the 1 whole large egg, 2 tbsp pure maple syrup, and 0.25 cup heavy cream until smooth. Gradually mix the wet ingredients into the dry mixture until just combined. The filling should hold together when pressed but still be crumbly - this ensures it will crisp up beautifully during baking.
Assemble the Log Rolls
Using a serrated knife, carefully slice each cooled sweet potato lengthwise into two equal halves, creating 6 long halves in total. Remove a thin layer of flesh from the cut side using a spoon to create a flat surface for assembly. This creates a clean base for your filling.
Spoon approximately 1 tablespoon of the spiced filling mixture onto each sweet potato half, spreading it evenly toward one end. For a savory variation, sprinkle each with a pinch of the 0.25 tsp garlic powder before rolling. Gently roll each half up tightly from the filled end, tucking in the sides as you go. Place the rolls seam-side down on a parchment-lined baking sheet.
Create the Crispy Lattice Topping
In a small bowl, combine the 0.5 cup all-purpose flour and 0.25 cup chopped fresh thyme leaves. Add the 0.25 cup heavy cream and mix until you have a thick, dough-like consistency. If needed, add 1-2 teaspoons more flour to achieve the right texture - it should hold together when pressed but still be workable.
Divide the dough into 6 equal portions and roll each into a thin rope about 1/8-inch thick. To create the lattice pattern, lay one rope diagonally across each log roll, then lay a second rope perpendicular to the first, crossing in the center. Press the ends gently to secure. The lattice should cover about 75% of each roll, leaving some areas exposed for maximum crispiness.
Bake to Golden Perfection
Preheat your oven to 375°F. Bake the assembled log rolls for 25-30 minutes until the lattice topping is golden brown and crispy, and the filling is bubbling through the gaps. The sweet potatoes should be tender throughout with a caramelized exterior.
For extra crispiness, transfer the baked rolls to a wire rack and let them cool for 10 minutes. Serve warm with additional maple syrup drizzled over the top or alongside vanilla ice cream for a decadent dessert experience. The contrast between the crisp lattice, tender sweet potato, and spiced filling makes each bite irresistible.
Pro Tips For Making Sweet Potato Log Roll
- Boil Until Fork-Tender: Sweet potatoes should sink like a stone and pierce easily with a knife—no peeking early or you’ll end up with a mushy mess. Aim for 45–55 minutes at a rolling boil, then let them cool slightly before peeling (hot skins slide off better, but don’t burn yourself).
- Slice Thin, Even Strips: Use a mandoline or sharp knife to cut the potatoes into ¼-inch-thick strips—thicker slices take forever to soften, thinner ones burn before they’re done. Soak the strips in cold water for 10 minutes first to remove excess starch (they’ll stick less when rolling).
- Skip the Overmixing: Once you add the egg, butter, cinnamon, and sugar, fold just until combined—overworking turns the filling gummy. Think "gentle folds" like tucking in a quilt, not kneading dough. The filling should hold together when rolled but still feel tender.
- Press Hard, Roll Tight: Don’t be shy with the pressure when wrapping the filling in foil—pack it firm so the edges seal and the log holds its shape. If it feels flimsy, add another layer of foil or chill for 10 minutes before baking (yes, even if you’re impatient).
Make-ahead tips for leftovers
Prep Ahead Strategy
Assemble the log rolls completely up to 24 hours before baking and refrigerate in an airtight container. The filling stays fresh, and the sweet potatoes maintain their moisture. When ready to bake, let them sit at room temperature for 30 minutes to ensure even cooking.
This method saves you from last-minute stress and lets flavors meld beautifully. 📅
Filling Prep
Make the spiced filling mixture a day ahead and store it in a small airtight container in the fridge. The butter and spices blend perfectly overnight, and the egg mixture stays stable.
When ready to roll, simply scoop and spread—no extra prep needed. For the savory version, keep the herbed cream cheese chilled until rolling time. ✨
Baking Timeline
Bake the log rolls just before serving for that restaurant-fresh crispiness. If you must reheat, place slices on a baking sheet at 350°F for 5-7 minutes to restore the lattice crunch. The filling reheats beautifully, but the lattice loses crispness quickly. Plan to bake fresh for the best experience. 🔥
Freezing Tips
Slice the baked log rolls into wedges and freeze them on a tray before transferring to a freezer bag for up to 3 months. Reheat frozen slices in a 375°F oven for 8-10 minutes—the lattice will crisp up again.
Label the bag with the date to track freshness. This is perfect for holiday prep! ❄️
Serving Prep
Slice the baked log rolls into wedge-shaped portions just before serving for that elegant presentation. Arrange them on a platter with a drizzle of maple syrup or a dusting of powdered sugar.
Garnish with fresh thyme leaves for a pop of color. Pre-sliced rolls stay fresh for 1 hour at room temperature. 💫
Make-Ahead Mistakes
Avoid refrigerating the assembled but unbaked rolls for more than 24 hours—the sweet potatoes can dry out. Skip the lattice topping if prepping ahead for more than a day; add it fresh before baking.
Never freeze unbaked rolls—they won’t hold their shape when thawed. Always let baked rolls cool completely before storing to prevent condensation. 💡

Frequently asked questions
Can I make this sweet potato log roll without a mandoline?
A sharp chef's knife works perfectly! Use a long, even stroke and keep the blade at a consistent angle (about 30 degrees) for uniform slices. For extra safety, wrap the sweet potato in plastic wrap first—it prevents slipping. If the slices aren't perfectly even, don't worry; the filling will hold everything together during baking.
How do I fix a log roll that's falling apart when rolling?
Cold sweet potatoes are the culprit! Let them cool completely after roasting, then chill in the fridge for 30 minutes before slicing. If they're still too soft, sprinkle the cut sides with a pinch of flour before rolling. For extra stability, add 1/2 teaspoon cornstarch to the filling mixture—it helps bind the layers during baking.
Can I use regular potatoes instead of sweet potatoes?
Not recommended—they lack the natural sweetness and moist texture that makes this dish special. However, you could try purple potatoes for a colorful twist, but expect a slightly denser result. Sweet potatoes are the star here; their natural sugars caramelize beautifully during baking, creating that perfect balance of sweet and spiced flavors.
What's the best way to reheat leftovers?
Place slices on a baking sheet at 350°F for 5-7 minutes to restore crispiness. For microwave reheating, cover with a damp paper towel for 15-20 seconds**—this prevents drying. The lattice topping won't be as crispy as fresh-baked, but the filling stays delicious. For maximum crunch, always reheat in the oven whenever possible.
How can I make this recipe vegan?
Swap the butter for vegan butter or coconut oil, use flax eggs (1 tbsp ground flax + 3 tbsp water per egg), and replace heavy cream with coconut cream. For the lattice, use a vegan flour blend. The flavor will still be rich and spiced, though the texture may be slightly denser. Test with a small batch first to adjust consistency.
