These marshmallow pecan yams are pure comfort and nostalgia for every holiday table I host. Silky yams are mashed with warm spices, lush cream, and brown sugar, then blanketed in pecans and bubbly marshmallows for a sweet-savory finish my whole family loves.
The first time I made this I was fretting over the turkey and barely noticed how fast my kids devoured the yam side. Now they insist it makes the feast. It has become a non-negotiable every year.
Ingredients
- Yams: Look for four large yams with firm unblemished skin and rich orange color for maximum flavor

- Unsalted butter: A half cup adds richness and helps all the flavors meld together

- Ground cinnamon and ground nutmeg: Warming spices for a familiar holiday aroma

- Pure vanilla extract: Enhances all the flavors with just a little extra aromatic sweetness

- Peel and chop the yams into one-inch pieces bring to a boil in a large pot of water with salt then simmer for about fifteen minutes You want them fork tender but not falling apart Drain them thoroughly so your mash will not be watery
- Mash the Yams:
- Transfer the cooked yams to a large mixing bowl and mash until mostly smooth with a few small lumps for texture
- Mix in Sweeteners Spices and Cream:
- Stir in melted butter brown sugar cinnamon nutmeg cream and vanilla Mix thoroughly so the mash turns silky and even
- Spread and Layer:
- Evenly smooth the mashed yam mixture into your prepared baking dish making sure it reaches all the corners for consistent baking
- Add Pecans and Marshmallows:
- Sprinkle the pecans over the surface so every bite has crunch Then top generously with mini marshmallows covering most of the top for a golden blanket
- Bake:
- Place in the oven uncovered Let bake for twenty to twenty five minutes until the marshmallows puff and turn golden and the filling is heated through

Pecans have always felt a little special to me My grandmother loved sprinkling toasted nuts on every sweet casserole and it is the bite I look forward to the most The crunch mixed with gooey marshmallow and creamy yams always brings vivid memories of her bustling kitchen
Storage Tips
If you have leftovers cool completely and store covered in the fridge for up to four days For best results reheat uncovered at 325 degrees until bubbly again If the marshmallows start to darken too much tent with foil
Ingredient Substitutions
Sweet potatoes work perfectly if you cannot find yams You can use half and half instead of heavy cream for a lighter version and coconut cream for dairy free Swap walnuts for pecans if that is what you have or go nut free for allergies
Serving Suggestions
This dish shines next to classic roast turkey or ham but it also complements vegetarian holiday spreads Try serving a scoop alongside maple glazed carrots or spinach salad for a bright contrast For an extra festive touch sprinkle with a few cranberries or orange zest before serving
Cultural and Historical Context
Marshmallow topped yams have become a beloved American tradition for Thanksgiving and other fall gatherings The sweet topping was popularized in twentieth century recipe booklets and quickly found its way into family cookbooks across the country Even today the debate on marshmallow or not is real
Seasonal Adaptations
Try using pumpkin or butternut squash instead of yams for a different twist Add a hint of clove or allspice for even warmer fall flavor Top with crushed ginger cookies for a little crunch and spice
