I was twenty-six before I ate a proper plate of these, at a holiday table in Charleston belonging to my friend Marcus's grandmother.
There were nine dishes on that table and one of them went back to the kitchen empty.
Not the ham.
The dish of dark orange rounds sitting in a glaze so thick it clung to the spoon.
I'd eaten something called candied yams plenty of times and never eaten this.
What I'd been served for years was baby food with marshmallows on it.
What she made was sliced sweet potato, whole and distinct, cooked slowly in butter and brown sugar until the edges genuinely candied.
She gave me the secret in four words while washing a pot: cover it, then don't.
That's it.
Covered, the slices steam tender in their own glaze.
Uncovered, the liquid reduces and the exposed edges take on color and turn sticky.
One thing before we go further, since it confuses everybody and it should: in the American South, the yams in candied yams are sweet potatoes.
Real yams are a different vegetable entirely, and I explain how the name stuck a few paragraphs down.
This is a soul food staple and a Southern holiday standard, and I make it every November with real respect for where I learned it.
My wife now considers it non-negotiable.
Why They Are Called Candied Yams (and Whether They Are Yams)
They are sweet potatoes. Almost every bag in an American grocery store labeled yam is holding an orange fleshed sweet potato.
A true yam is a starchy West African tuber with rough, bark-like skin and pale, dry, mealy flesh. It's a different plant family altogether, and most US supermarkets have never carried one.
The name traveled with people.
Enslaved West Africans brought to the American South found the sweet potato the closest thing available to the yams of home, and the word carried over.
It stuck so firmly that when orange fleshed varieties were introduced commercially in the twentieth century, growers marketed them as yams to distinguish them from the paler ones already on shelves.
The USDA still allows the label, as long as the words sweet potato appear somewhere on the package.
So when a recipe says candied yams, it means sweet potatoes, and it means a dish with a real history behind it.
Candied Yams vs Sweet Potato Casserole
These are two different dishes and half the internet has them tangled together. Here's the clean line.
- Candied yams. Sliced into rounds, glazed in butter and sugar, baked. The pieces stay whole and distinct, and you can see every slice on the spoon. That's this recipe.
- Sweet potato casserole. Cooked, mashed, bound with egg and cream, then topped with either marshmallows or a brown sugar pecan streusel. Soft all the way through.
Both are legitimate, both show up on holiday tables, and plenty of families serve both without thinking twice about it.
If the dish you remember was smooth and you ate it with a fork like pie, that was the casserole.
If you remember picking out individual sticky slices, that was this.
Ingredients You Need
Nine ingredients and you probably have seven of them. Every single one is doing a specific job, so here's what each one is for.
The Sweet Potatoes
- Sweet potatoes (3 pounds, about 4 to 5 medium). Peeled and cut into ½ inch thick rounds. Pick firm ones with no soft spots and try to buy them all a similar width.
Uniform thickness matters more than the exact count. Mixed thicknesses mean thin slices collapsing into mush while thick ones are still firm in the middle.
If a potato is much fatter than the rest, cut it into half moons so every piece is the same size.
The Two Sugars
- Dark brown sugar (1 cup, packed). The molasses in it is what gives the glaze its depth and its dark color. Light brown works but the result is noticeably thinner in flavor.
- Granulated sugar (½ cup). This is the one people skip and shouldn't. White sugar sets a cleaner, glossier glaze, while brown sugar alone stays a little muddy and soft.
Every serious version of this dish uses both, and now you know why.
The Butter
- Unsalted butter (½ cup, 1 stick). Unsalted so you control the salt yourself. Butter is the fat that makes the glaze cling to the slices rather than running straight to the bottom of the dish.
The Warm Spices
- Ground cinnamon (1 ½ teaspoons). The backbone.
- Ground nutmeg (¾ teaspoon). Freshly grated if you have a whole one, and the difference is bigger than you'd expect.
Skip the pumpkin pie spice. It carries cloves and allspice that turn this dish into a pie filling, and clove in particular goes bitter and takes over.
Vanilla, Cream, and Salt
- Vanilla extract (2 teaspoons). The best small idea in this whole recipe. It rounds off the raw edge of a cup and a half of sugar.
- Heavy cream (2 tablespoons). A tiny amount, and it's what makes the glaze look opaque and clinging instead of thin and syrupy.
- Kosher salt (½ teaspoon). A candied dish needs real salt or the sweetness has nothing to push against.
Not in this recipe: marshmallows, which belong to the casserole, and maple syrup, which is a lovely thing that has no business competing with molasses here.
How to Make Southern Candied Yams
The oven does almost all of it, and the technique is the covering schedule. Everything else is prep.
Prep the Sweet Potatoes
Heat the oven to 375°F and butter a 9x13 inch baking dish.
Peel the potatoes and cut them into ½ inch rounds.
Lay them in the dish in overlapping rows, like shingles, rather than piling them in.
Overlapping means the glaze reaches more of every slice, and it looks like the dish it's supposed to be when it comes out.
Make the Brown Sugar Butter Glaze
Melt the butter in a saucepan over medium heat.
Add both sugars, the cinnamon, the nutmeg, and the salt, and whisk until the mixture is completely smooth and you can't feel any grit on the bottom of the pan, about 2 to 3 minutes.
Pull it off the heat and stir in the cream and the vanilla.
Dissolving the sugar first is the insurance step. Sprinkle raw sugar over raw potatoes and you get gritty patches where it never fully melted, which is a small disappointment that shows up in a lot of home versions.
Pour the hot glaze evenly over the slices.
Cover, Bake, Then Uncover
This is the part that decides whether the dish works.
Cover the dish tightly with foil and bake 40 minutes.
The slices steam in the glaze and go tender without drying at the edges.
Take the foil off, baste the slices with the liquid in the dish, and bake another 20 to 25 minutes.
Now the liquid reduces and the exposed tops take on color.
That's what candied means. Not sugar poured over vegetables, but sugar cooked down onto them until it sticks.
They're done when a knife goes through a slice easily and the glaze has visibly thickened and darkened around the edges of the dish.
Reduce the Glaze if You Need To
Sometimes it comes out thin, and it isn't your fault.
Sweet potatoes release a variable amount of water depending on the potato, how it was stored, and how thick you cut it, so no fixed bake time can guarantee the right consistency.
You have two fixes.
- More uncovered time. Another 10 minutes with the foil off, basting halfway. Easiest option if you have the oven space.
- Reduce it separately. Tip the liquid into a saucepan and boil it hard for 3 to 5 minutes until it coats a spoon, then pour it back over the slices. Faster and completely reliable.
Rest Before Serving
Give it 10 to 15 minutes out of the oven.
Straight from the heat that glaze is molten sugar and butter, and it will both burn a mouth and run right off the slices.
As it cools slightly it thickens and clings, which is exactly what you want on the spoon.
Tips, Substitutions, and Troubleshooting
- Watery glaze. Almost always too much moisture from the potatoes. Uncover for longer or reduce the liquid separately in a pan. Both work.
- Gritty glaze. The sugar never dissolved. Melt it into the butter over heat first, and whisk until you feel nothing on the bottom of the pan.
- Slices falling apart. Cut too thin, or covered for too long. Stick to ½ inch and pull the foil at 40 minutes.
- Slices still firm. Cut too thick or unevenly. Cover again and give it another 10 minutes before you go back to the uncovered stage.
- Too sweet for your table. Drop the granulated sugar to ¼ cup. Keep all the brown sugar, because that's where the flavor lives.
- Canned yams. They're already cooked, so drain them well, skip the covered stage entirely, and bake uncovered 25 to 30 minutes. Fine in a pinch, softer in the finish.
- Stovetop instead. Simmer the slices in the glaze with 1 cup of water in a wide pot for about 40 minutes. Faster, looser syrup, softer slices, and no caramelized edges. A real version of the dish, just a different one.
- Your family does marshmallows. Scatter them over the last 5 minutes of uncovered baking. I don't, but I'm not going to pretend nobody does.
- A pecan finish. A cup of toasted chopped pecans over the top for the final 10 minutes adds crunch against all that softness.
What to Serve With Candied Yams
This dish is sweet, so it wants salt and bitterness sitting next to it. The traditional Southern holiday plate handles that without even trying.
- The mains. Roast turkey, a baked ham with a salty glaze, fried chicken, smothered pork chops.
- Collard greens. The single best partner on the table. Bitter, vinegary, and cooked with smoked meat, which is everything this dish isn't.
- Macaroni and cheese. Sharp, salty, and rich. A holiday plate classic for good reason.
- Cornbread dressing. Savory, herby, and it soaks up the glaze that runs across the plate.
- Black eyed peas and green beans. Both earthy and both a relief between sweet bites.
What I wouldn't put beside it: glazed carrots or a second sweet side. One sugary dish per plate is plenty.
Storing and Reheating Leftovers
- In the fridge. 4 to 5 days in an airtight container, kept in their glaze. The glaze will firm up cold, which is normal.
- Reheating. Covered at 325°F for 20 minutes with a splash of water to loosen the glaze. They come back almost perfectly.
- The microwave. Works but the glaze separates into butter and syrup. Stir it back together and nobody will notice, but the oven is better.
- Freezing. 3 months, though the slices soften and lose some of their shape. Freeze them in the glaze, never drained.
Make It Ahead for the Holidays
Oven space is the real constraint on Thanksgiving, not time. There are two ways to buy yourself some.
- Assemble ahead, bake fresh. Slice the potatoes, make the glaze, pour it over, cover, and refrigerate up to 1 day. Add 10 minutes to the covered stage since it's going in cold.
- Bake ahead, reheat. Make the whole dish the day before, cool it, and refrigerate. Reheat covered at 325°F for 25 to 30 minutes. Honestly the glaze is a little better on day two.
Pro tip: peeled and sliced sweet potatoes will hold overnight submerged in cold water in the fridge. Drain and pat them dry before the glaze goes on.
Frequently Asked Questions
Are candied yams actually yams, or are they sweet potatoes?
They're sweet potatoes. True yams are a starchy West African tuber with rough skin and pale, dry flesh, and most American grocery stores never stock them. The name carried over from West African foodways in the South, and growers later used it commercially to distinguish orange fleshed varieties from paler ones. The USDA permits the yam label as long as sweet potato also appears on the package.
What is the difference between candied yams and sweet potato casserole?
Candied yams are sliced into rounds and glazed in butter and sugar, so the pieces stay whole and distinct. Sweet potato casserole is mashed, bound with egg and cream, and topped with marshmallows or a pecan streusel. Both are holiday dishes and plenty of families serve both. This recipe is the sliced, glazed version.
Do you cover candied yams when you put them in the oven?
Both, in that order. Cover tightly with foil for the first 40 minutes so the slices steam tender in the glaze without drying out at the edges. Then uncover for the last 20 to 25 minutes so the liquid reduces and the exposed tops take on color. Uncovered the whole time and they dry out. Covered the whole time and you get a thin, watery glaze.
What is the secret to candied yams?
Three things. Melt the sugars into the butter until fully dissolved before the glaze touches the potatoes, so you never get gritty patches. Cover, then uncover, which is what actually candies the edges. And reduce the glaze at the end if it looks thin, because that's what makes it cling instead of pool.
How do I make the glaze thicker if it comes out watery?
Either bake uncovered for another 10 minutes, basting halfway, or pour the pan liquid into a saucepan and boil it hard for 3 to 5 minutes until it coats a spoon, then pour it back over. Sweet potatoes release different amounts of water depending on the potato, so a thin glaze is common and easy to fix.
Can I use canned yams, and how does the method change?
You can. Drain them thoroughly, arrange them in the dish, pour the glaze over, and bake uncovered for 25 to 30 minutes. Skip the covered stage completely, since they're already cooked and will fall apart. The texture is softer than fresh, but the glaze is the same.
Can I make candied yams ahead of Thanksgiving?
Yes, and I usually do. Assemble the dish with the glaze, cover, and refrigerate up to 1 day, then add 10 minutes to the covered bake because it's going in cold. Or bake it fully the day before and reheat covered at 325°F for 25 to 30 minutes.
Should I put marshmallows on top?
Not in this version, no. Marshmallows belong to sweet potato casserole, which is the mashed dish. That said, plenty of families put them on candied yams and have done for generations. If that's your table, scatter them over for the last 5 minutes of uncovered baking.
Recipe
Southern Candied Yams Baked in Brown Sugar Butter Glaze
Ingredients
For the Yams
- 3 lb sweet potatoes about 4 to 5 medium, peeled and cut into ½ inch thick rounds
For the Brown Sugar Butter Glaze
- ½ cup unsalted butter 1 stick, plus more for the dish
- 1 cup dark brown sugar packed
- ½ cup granulated sugar
- 1 ½ teaspoon ground cinnamon
- ¾ teaspoon ground nutmeg freshly grated if possible
- ½ teaspoon kosher salt
- 2 tablespoon heavy cream
- 2 teaspoon vanilla extract
Instructions
Prep the Sweet Potatoes
- Heat the oven to 375°F and butter a 9x13 inch baking dish.
- Peel the sweet potatoes and cut them into even ½ inch thick rounds. Cut any unusually wide potato into half moons so every piece is the same size.
- Lay the rounds in the dish in overlapping rows rather than piling them in, so the glaze reaches more of every slice.
Make the Glaze
- Melt the butter in a saucepan over medium heat.
- Whisk in the dark brown sugar, granulated sugar, cinnamon, nutmeg, and salt and cook 2 to 3 minutes, until completely smooth with no grit on the bottom of the pan.
- Take the pan off the heat and stir in the heavy cream and vanilla, then pour the hot glaze evenly over the sweet potato rounds.
Cover, Bake, Then Uncover
- Cover the dish tightly with foil and bake 40 minutes, so the slices steam tender in the glaze.
- Remove the foil, baste the slices with the liquid in the dish, and bake another 20 to 25 minutes, until a knife goes through a slice easily and the glaze has thickened and darkened at the edges.
- If the glaze is still thin, either bake uncovered 10 minutes longer or pour the liquid into a saucepan and boil it 3 to 5 minutes until it coats a spoon, then pour it back over.
- Rest 10 to 15 minutes before serving so the glaze thickens and clings to the slices.
Notes
- Yams are sweet potatoes: In the American South the yams in candied yams are orange fleshed sweet potatoes. True yams are a different West African tuber.
- Cover then uncover: 40 minutes covered makes the slices tender, 20 to 25 uncovered is what candies the edges and reduces the glaze.
- Dissolve the sugar first: Melting both sugars into the butter prevents gritty patches in the finished glaze.
- Uniform slices: Even ½ inch rounds cook at the same rate. Mixed thicknesses give you mush next to firm.
- Thin glaze fix: Boil the pan liquid down for 3 to 5 minutes and pour it back over.
- Not the casserole: This is the sliced, glazed dish. Marshmallows belong to mashed sweet potato casserole, though you can add them for the last 5 minutes if that is your family's version.
