Candied Yams Marshmallow Pecan

There's something about the smell of cinnamon and brown sugar hitting the oven that just says home to me. My grandmother would make candied yams every Thanksgiving, and honestly, I spent more time hovering near the kitchen door watching those marshmallows turn golden than I did anywhere else at dinner. The first time I actually made it myself, I was terrified I'd either burn the whole thing or somehow mess up what seemed so simple. Turns out, the magic is in patience and knowing when to pull it out before the topping goes from crispy to charred.

I made this for a potluck last year and watched someone who'd been complaining about yams all evening take three helpings without saying a word. That's when I knew the marshmallow topping wasn't just nostalgia talking—it actually transforms the whole dish into something people genuinely want to eat.

Ingredients

• Yams (sweet potatoes): Get the larger ones if you can find them, as they cook more evenly and the slices stay intact better during baking.
• Brown sugar: Don't skip packing it down when measuring—this is where most of your sweetness and that deep caramel flavor come from.
• Unsalted butter: You'll use it twice, once melted into the glaze and once softened for the crumble topping.
• Maple syrup: This adds a subtle woody note that keeps things from tasting one-dimensional.
• Heavy cream: Makes the glaze silky instead of thin and watery.
• Cinnamon and nutmeg: The spice ratio here is gentle—if you prefer boldness, cinnamon especially can handle a bit more.
• Vanilla extract: Use real vanilla if you have it; the flavor difference shows up.
• Mini marshmallows: Stick with mini rather than full-size ones so they distribute evenly and toast properly.
• Pecans: Roughly chop them by hand rather than using a food processor, which turns them into dust.
• All-purpose flour: Keeps the crumble from being too soft and helps it stay crispy as it bakes.

Instructions

Set your oven and prep:

Get your oven to 375°F and grease that 9x13 dish well so nothing sticks. I use butter for this because it flavors the edges just right.

Layer in your yams:

Peel your yams and slice them into inch-thick rounds, then arrange them in the dish in a single layer so they cook evenly.

Make the glaze magic:

Whisk together the brown sugar, melted butter, maple syrup, cream, and spices until it's smooth and glossy. The vanilla goes in last so it doesn't cook off prematurely.

Coat and cover:

Pour that glaze all over the yams and toss gently to make sure every piece gets coated. Seal it tight with foil—this trapped steam is what makes them tender.

First bake:

Bake covered for 30 minutes, then remove the foil, give them a gentle stir to redistribute the glaze, and bake uncovered for 10 more minutes until the yams are fork-tender.

Crumble time:

While the yams finish, mix your pecans, flour, brown sugar, softened butter, cinnamon, and salt in a bowl, using a fork to break it all into uneven crumbles.

The final assembly:

Top the hot yams with an even layer of mini marshmallows, then scatter that pecan crumble over top, making sure you get some of each in every bite.

Final bake and watch closely:

Return everything to the oven for 5 to 7 minutes until the marshmallows puff up and turn golden and the crumble edges brown slightly. This is the moment you absolutely cannot look away—once they hit that golden sweet spot, they can burn in seconds.

Rest and serve:

Let it cool for a few minutes so everything sets slightly and you're not burning your mouth on molten marshmallow.

Save

My sister made this for her first time and called me halfway through panicking because the marshmallows looked like they were bubbling too much. I told her to watch for that moment when they turn from white to just barely golden, and she pulled it out at exactly the right second. She's been making it every holiday since, and now her kids request it by name.

Making It Your Own

The spice profile here is a starting point, not gospel. I've added a tiny pinch of allspice or cloves and it deepens everything beautifully, especially if you're serving this alongside savory dishes. Some people use walnuts instead of pecans, which works perfectly fine and actually costs less most times.

Getting Ahead

If you're cooking for a big meal and every oven minute counts, you can assemble everything the morning of, cover it, and refrigerate it. Just add a few extra minutes to the bake time since it'll start cold. I've done this dozens of times and it hasn't failed me yet.

Serving and Storage

This dish is most delicious served warm or at room temperature, and it's one of those sides that somehow gets eaten as much as the main course. Leftovers keep in the fridge for three days, though honestly they never last that long in my house.

• If you're making this for a holiday crowd, doubling the recipe in two separate dishes means you can coordinate your oven timing better.
• The pecan crumble can be mixed together a day ahead and stored in an airtight container, then scattered over just before baking.
• This dish travels well in a covered baking dish if you're bringing it to someone else's table.

Save

This recipe turned a vegetable I used to avoid into something I actually crave, which tells you everything about how the right combination of flavors and textures can change things. Make it once and you'll understand why it's been a table staple for generations.
