Ingredient Notes & Details

Sweet potatoes
Use fresh, firm sweet potatoes. For natural sweetness, look for orange-fleshed varieties. Avoid watery ones for the creamiest texture.

Brown sugar
Adds rich, caramel-like sweetness. You can substitute with coconut sugar for a slightly healthier twist.

Butter
Unsalted butter is ideal so you can control salt levels. It contributes to creaminess and depth of flavor.

Eggs
Provide structure and help the casserole set. Large eggs work best.

Vanilla extract
Enhances the natural sweetness of the sweet potatoes and adds warmth.

Ground cinnamon & nutmeg
Essential for that classic holiday flavor. Freshly grated nutmeg makes a noticeable difference.

Pecans
Toast lightly for maximum flavor. They add a satisfying crunch that complements the smooth potatoes.

Optional marshmallows
A traditional topping for extra sweetness and nostalgia, especially for holiday tables.

Step-by-Step Instructions

Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with butter or nonstick spray.

Boil the sweet potatoes until tender, about 20–25 minutes. You should be able to pierce them easily with a fork. Drain and let them cool slightly.

Mash the sweet potatoes in a large mixing bowl. Add butter, brown sugar, eggs, vanilla, cinnamon, and nutmeg. Mix until smooth and creamy. Taste and adjust sweetness if needed.

Transfer to the baking dish, spreading evenly with a spatula.

Prepare the topping by mixing pecans, brown sugar, and a touch of melted butter. Sprinkle evenly over the sweet potato mixture. For a classic twist, top with marshmallows as well.

Bake uncovered for 25–30 minutes, until the topping is golden and bubbly. Keep an eye on the marshmallows—they should be lightly toasted, not burnt.

Cool slightly before serving to allow flavors to meld. The casserole will thicken as it cools, making it easier to serve.
