Sticky Brown Sugar Candied Sweet Potatoes
These candied sweet potatoes are the holiday side I make year after year. Tender slices bake in a buttery brown sugar syrup until every piece is glossy and sticky.
No cans, no shortcuts. You pour a simple stovetop syrup over fresh sweet potatoes and let the oven do the work, and the result tastes deep and caramel-like without being cloying.
Why These Candied Sweet Potatoes Work
The brown sugar and butter melt into a syrup that clings to the potatoes in a glossy, caramel-like coat. It thickens just enough in the oven to hold onto every slice without turning watery.
They are sweet enough to feel like a treat but still balance a savory plate. The cinnamon and nutmeg give them that warm holiday backbone, and the vanilla rounds everything out with a soft, almost butterscotch note.
Leftovers hold up well, too. The glaze stays sticky even after a few days in the fridge and reheats without separating into a greasy mess.
Ingredients
- 3 lbs sweet potatoes, peeled and sliced into 1/2-inch rounds: even thickness helps them bake at the same rate.
- 1/2 cup (1 stick) unsalted butter: salted butter works; just cut the added salt by half.
- 1 cup packed light brown sugar: dark brown sugar gives a deeper molasses edge if you prefer it.
- 1/3 cup water: this keeps the sugar from scorching while the butter melts.
- 1 tsp ground cinnamon: the warm, familiar base note.
- 1/4 tsp ground nutmeg: a little goes a long way for that holiday warmth.
- 1/4 tsp kosher salt: it sharpens the sweetness so the dish doesn’t taste flat.
- 1 tsp vanilla extract: stir it in after the heat is off so the flavor stays bright.
- 1 cup mini marshmallows (optional): for the classic toasted top.
Variations / Substitutions
- Dairy-free: swap the butter for a good vegan butter stick or refined coconut oil. The texture stays silky.
- Less sweet: cut the brown sugar to 3/4 cup and rely more on the natural sweetness of the potatoes.
- Spice swap: pumpkin pie spice or a pinch of ground ginger and allspice works neatly in place of the cinnamon and nutmeg.
- Add crunch: scatter toasted pecans over the top when you pull the dish from the oven.

How to Make Sticky Brown Sugar Candied Sweet Potatoes
Step 1: Make the Syrup
In a small saucepan over medium heat, combine the 1/2 cup butter, 1 cup brown sugar, 1/3 cup water, 1 tsp cinnamon, 1/4 tsp nutmeg, and 1/4 tsp salt. Cook, stirring occasionally, until the butter melts and the sugar dissolves, about 3 minutes. Remove the pan from the heat and stir in the 1 tsp vanilla.
The syrup will look thin and glossy at this point. It thickens as it bakes, so don’t worry if it seems too loose right now.
Step 2: Layer the Potatoes
Preheat the oven to 375°F. Arrange the sliced sweet potatoes in a 9×13-inch baking dish, overlapping them slightly if you need to fit them all. Pour the warm syrup evenly over the potatoes, then gently nudge the slices so some of the syrup slips between the layers.
The potatoes won’t be fully submerged, but the syrup will coat every slice as they bake. Keeping them in a mostly single layer with only small gaps helps the edges caramelize instead of steam.
Step 3: Bake the Potatoes
Bake uncovered for 45 to 50 minutes, basting the potatoes with the pan juices once around the 25-minute mark.
You will know they are done when a knife slides through a slice with zero resistance and the syrup is bubbly and thick. The edges of the top slices will look dark and sticky, and the kitchen will smell like warm butter and cinnamon.
Step 4: Finish and Serve
If you are adding marshmallows, scatter the 1 cup mini marshmallows over the top and broil for 1 to 2 minutes, just until they are puffed and golden. Otherwise, spoon some of the sticky pan syrup over the potatoes and serve them hot, right from the dish.
Watch the marshmallows closely under the broiler. They go from toasted to burnt in seconds. Serve these while they are still warm so the glaze stays fluid and glossy on the spoon.
A Few Tips for the Best Candied Sweet Potatoes
- Pick similar-sized potatoes: Sweet potatoes that are roughly the same diameter will bake at the same rate, so you avoid some slices turning to mush while others stay firm.
- Tent if browning too fast: If the top edges darken before the centers are tender, lay a piece of foil loosely over the dish and keep baking. The foil traps just enough steam to finish cooking without burning the sugar.
- When the syrup looks thin: If your pan juices seem watery after baking, the potatoes released more liquid than usual. Pour the liquid into a small saucepan, boil it for a minute or two until it reduces, then pour it back over the potatoes.
- Marshmallow timing matters: Only slide the dish under the broiler once the potatoes are completely tender. If they still have any firmness, the marshmallows will melt before the potatoes finish.
Bake times by slice thickness:
| Slice Thickness | Bake Time | Texture |
|---|---|---|
| 1/4 inch | 35 to 40 mins | soft and almost jammy |
| 1/2 inch | 45 to 50 mins | tender with some bite |
| 3/4 inch | 55 to 60 mins | firm but yielding |
Storing and Reheating Leftovers
Refrigerate leftovers in an airtight container for up to 4 days. Reheat them in a microwave-safe dish or covered in a 350°F oven until warmed through. The syrup may look a little separated when cold, but a quick stir brings it back together.
What Goes Well With Candied Sweet Potatoes
These sweet potatoes are a natural alongside roast turkey on Thanksgiving. The sticky glaze also pairs beautifully with a salty glazed ham or a simple roast chicken. For a full holiday plate, add something savory and creamy, like mashed potatoes or a green bean casserole, to balance the sweetness.
Frequently Asked Questions
Do I need to boil the sweet potatoes first?
No. Baking raw slices directly in the syrup works perfectly. They soften and absorb the glaze without any extra step.
Are yams the same as sweet potatoes?
In most U.S. grocery stores, what is sold as a yam is actually a sweet potato with orange flesh. Use whatever your market labels as sweet potatoes; the orange-fleshed varieties work best here.
Can I freeze candied sweet potatoes?
It is not recommended. Freezing turns the texture watery and a little grainy after thawing. They keep well in the fridge and reheat nicely, so freezing is not worth the tradeoff.
