Candied Yams Recipe (The Real Southern Stovetop Version)

Candied yams are sliced sweet potatoes simmered in a butter, brown sugar, and cinnamon syrup until tender and glazed, made on the stovetop or finished in the oven, with marshmallows entirely optional depending on which side of the family you grew up in.

The name bothered me for years before I finally looked into it. What everyone calls a yam at Thanksgiving is a sweet potato. Real yams are a dry, starchy tuber almost nobody in the US has ever cooked with, and the naming mix-up goes back nearly a century.

None of that changes how good the dish is. It’s just worth knowing before someone at the table corrects you.

Key Takeaways

• What Americans call yams at the grocery store are botanically sweet potatoes, a naming confusion that traces back to 1930s marketing
• The stovetop method (parboil, then simmer in syrup) and the oven method (bake covered, then uncovered to glaze) both work, they just trade convenience for hands-off time
• Uncovering the dish for the last stretch of oven baking is the single most important step, since a covered dish traps steam and keeps the syrup watery
• Marshmallows are a real, genuine regional and family split, not a required ingredient
• Candied yams and sweet potato casserole are two different dishes: one keeps distinct pieces in a glaze, the other is mashed and baked smooth

Why It’s Called Yams When It’s Sweet Potatoes

In the 1930s, Louisiana growers started marketing a new, softer, orange-fleshed sweet potato and needed a way to set it apart from the older, drier white sweet potato already on shelves. They borrowed the word yam, which had already been used informally in Black American communities with roots in West African terms for a genuinely different tuber.

The name stuck well enough that the USDA now requires any product labeled “yam” in US grocery stores to also say “sweet potato” somewhere on the packaging, since the two are still commonly confused. So when a recipe calls for yams, in nearly every American kitchen, it means sweet potatoes.

Ingredients

Sweet potatoes, 3 to 4 lbs (4 to 6 medium): Peeled and sliced into rounds or wedges about 1/2 inch thick. A Y-shaped vegetable peeler makes quick work of this for a big batch.

Unsalted butter, 1/2 cup (1 stick)

Brown sugar, 1 to 1.5 cups: Light or dark both work. Dark brown sugar gives a deeper, slightly more bitter caramel note from the extra molasses.

Ground cinnamon, 1 teaspoon

Ground nutmeg, 1/4 teaspoon

Vanilla extract, 1 teaspoon

Salt, a pinch

Mini marshmallows, 2 to 3 cups, optional: Add these only in the final 5 to 10 minutes if you’re using them. Any earlier and they melt straight into the syrup instead of staying puffed on top.

Equipment

For the stovetop method, a heavy-bottomed pot or Dutch oven matters more than it sounds like it would. Sugar syrup scorches fast in a thin pan, and once it burns there’s no saving it. The same 6-quart enameled Dutch oven I use for soups works well here too.

For the oven method, a solid 9×13 baking dish is what nearly every published version of this recipe calls for. A Pyrex 9×13 glass dish lets you see the syrup reducing through the sides, which is genuinely useful for judging doneness.

A basting brush or spoon earns its place here too, since basting the potatoes every 15 to 20 minutes is a real, repeated step in almost every version of this dish, not an optional flourish.

How to Make Candied Yams (Stovetop Method)

This is the faster of the two methods, and the one I reach for on a weeknight or when the oven is already full of other things.

Step 1: Parboil the sweet potatoes

Bring a pot of water to a boil and add the sliced sweet potatoes. Cook until just barely fork-tender, about 10 to 12 minutes. You want resistance still there, since they’ll cook further in the syrup. Drain and set aside.

Step 2: Build the syrup

In the same pot, melt the butter over medium heat. Stir in the brown sugar, cinnamon, nutmeg, vanilla, and salt, and bring it to a gentle boil, stirring so the sugar doesn’t stick to the bottom.

Step 3: Simmer the potatoes in the syrup

Return the drained sweet potatoes to the pot. Reduce the heat to medium-low and simmer, basting the potatoes with the syrup every few minutes, for 20 to 30 minutes, until the syrup has reduced into a glossy glaze that coats each piece.

Keep the heat no higher than medium-low the entire time. High heat is what scorches the sugar before it’s had time to reduce properly.

How to Make Candied Yams (Oven Method)

This version needs less attention once it’s in the oven, which makes it the better choice if you’re juggling a full Thanksgiving spread.

Step 1: Assemble the dish

Preheat the oven to 350 degrees. Arrange the sliced sweet potatoes in a buttered 9×13 baking dish.

Step 2: Pour over the syrup

Combine the melted butter, brown sugar, cinnamon, nutmeg, vanilla, and salt, and pour it evenly over the potatoes.

Step 3: Bake covered, then uncovered

Cover the dish with foil and bake for 35 to 45 minutes, basting every 15 to 20 minutes. Then uncover and bake another 10 to 20 minutes, until the syrup has reduced and started to caramelize at the edges rather than just pooling around the potatoes.

This uncovering step is the one people skip most often, and it’s the reason so many home versions end up swimming in thin syrup instead of glazed. If you’re adding marshmallows, scatter them on top only for this final uncovered stretch.

The Marshmallow Question

Whether candied yams get marshmallows on top is a real divide, not a manufactured internet debate. Some families have never made the dish any other way. Others consider marshmallows something that belongs on sweet potato casserole, not on this.

That split points to something worth clearing up: candied yams and sweet potato casserole are genuinely two different dishes, not two names for the same thing. Candied yams keep the sweet potato in distinct sliced or cubed pieces sitting in a syrup glaze. Sweet potato casserole is mashed smooth and baked like a custard, almost always topped with something crunchy, marshmallows or a pecan streusel.

If you grew up with marshmallows on your candied yams, add them for the last stretch of baking. If you didn’t, the dish is complete without them.

Storage and Reheating

Refrigerate leftovers in an airtight container for 3 to 5 days.

This freezes better than a lot of side dishes do, generally 3 to 6 months in a freezer-safe container, since the sugar and butter content limits how much the texture suffers from ice crystals. Thaw in the fridge overnight before reheating.

Reheat covered in a 350-degree oven for about 20 minutes, or in the microwave, and add a splash of water or orange juice if the syrup has thickened too much sitting in the fridge.

Getting the Syrup Right Is the Whole Recipe

Everything else about this dish is forgiving. The syrup is not. Parboil until just tender, keep the heat moderate, baste often, and uncover the dish for the final stretch if you’re baking it. Do those four things and the glaze takes care of itself.
