Sweet Potato Casserole with Marshmallows is my go-to when I need a quick wow.

Think of this Sweet Potato Casserole with Marshmallows as a reliable hug on a busy day. The creamy base comes from mashed potatoes, eggs, milk, butter, vanilla, and cinnamon. Marshmallows on top melt into a glossy, gold-bronze crown that treks well from stovetop to table. Pecans bring a welcome crunch and nutty warmth.

A comfort-first dish with a chef’s touch

I treat this casserole like a hug you can bake. I start with warm spices that welcome every palate. The marshmallows reward patience with a glossy melt on top. A bit of salt lifts the sweetness and keeps flavors honest.

How the texture stays creamy and the top stays golden

Patience in the oven matters. Bake gently to meld flavors without drying. If you whisk too long, it becomes heavy; fold in the milk to keep lightness. The marshmallows should melt at the last moment for perfect caramelization. A light broil risks burning; stay at 350°F and watch closely.

Ingredients Sweet Potato Casserole with Marshmallows

This Sweet Potato Casserole with Marshmallows starts with a creamy base and ends with a fluffy, golden top.

The star is the mash, gently seasoned, then crowned with marshmallows and a crunchy nut topping.

Exact quantities are at the bottom of the article and available for printing.

Base ingredients for the creamy sweet potato layer

4 cups mashed sweet potatoes — about 4 large potatoes, peeled and cooked; this forms the creamy foundation.
½ cup granulated sugar — balances sweetness; adjust to taste for kids or holidays.
2 eggs, beaten — helps the mash set and hold together when baking.
½ cup milk — adds softness; use dairy or lactose-free milk as needed.
¼ cup unsalted butter, melted — rich and velvety; swap with dairy-free butter if desired.
1 tsp vanilla extract — brings warmth and depth to the sweetness.
½ tsp ground cinnamon — the cozy spice that defines the dish.
¼ tsp salt — brightens flavors and balances sweetness.

Topping elements and optional add-ins

1½ cups mini marshmallows — the gooey crown that makes this a holiday favorite.
½ cup chopped pecans — toasted for crunch and nutty warmth.
2 tbsp brown sugar — caramelizes on top for a subtle crust.
1 tbsp melted butter — helps the topping brown and stay crisp.
Optional add-ins — a pinch of nutmeg or allspice, a drizzle of maple syrup, or a handful of toasted coconut for extra texture.

How to Make Sweet Potato Casserole with Marshmallows

Step 1 — Preheat and prep for Sweet Potato Casserole with Marshmallows

I preheat the oven to 350°F. This Sweet Potato Casserole with Marshmallows starts with that warm, reliable step.

I lightly grease a 9×13-inch baking dish. This helps the casserole release cleanly when done.

I gather the base ingredients and topping components. Having everything at hand saves time in a busy kitchen.

If you’re making ahead, you can assemble and refrigerate up to 1 day. Bake later for a fresh finish.

Step 2 — Mash potatoes with sugar, eggs, milk, butter, vanilla, cinnamon, and salt

In a large bowl, mash the cooked sweet potatoes until smooth.

Stir in granulated sugar, eggs, milk, melted butter, vanilla, cinnamon, and salt.

Whisk until the mash is creamy and uniform.

If it looks thick, whisk in a splash more milk. Keep it dreamy and spreadable.

Step 3 — Spread the base evenly in the baking dish

Pour the mashed potato mixture into the prepared dish.

Spread it into an even layer.

Gently shake the pan to level the surface. A smooth base bakes evenly.

Step 4 — Mix pecans with brown sugar and melted butter, sprinkle over

In a small bowl, toss chopped pecans with brown sugar and melted butter.

Spread the nut topping over the potato base. The brown sugar adds a caramel kiss.

Step 5 — Bake, top with marshmallows, then finish until gooey and golden

Bake, top with marshmallows, then finish until gooey and golden

Place the dish in the 350°F oven and bake for 25 minutes.

Scatter mini marshmallows over the hot casserole.

Return to the oven for 10–15 minutes, until marshmallows are golden and gooey. If they brown too quickly, tent loosely with foil.

Let the casserole rest a few minutes before serving. The mash will firm up slightly as it cools.

Variations

Healthier or lighter options

For a lighter Sweet Potato Casserole with Marshmallows, cut the sugar by half and balance with a light drizzle of pure maple syrup after baking.
Swap half the butter for a neutral oil or applesauce to trim fat while keeping the mash silky.
Use dairy-free milk (almond, oat, or soy) and add a small amount of dairy-free yogurt for creaminess if you like.
If you’re watching cholesterol, try 1 whole egg with 1 egg white to help set the mash without heaviness.
Omit or reduce marshmallows and top with a cinnamon-crumb streusel for a lighter finish you can still savor.

Dairy-free, gluten-free, and maple-inspired twists

Make it dairy-free by using dairy-free butter and dairy-free milk; choose marshmallows labeled vegan or dairy-free.
Gluten-free by nature, but double-check any topping additions (use gluten-free oats or skip oats altogether).
Maple-inspired: swap in 2–3 tablespoons of real maple syrup for part of the sugar, and finish with a maple drizzle at the table.
Try toasted pumpkin seeds or chopped hazelnuts in place of or alongside pecans for a new flavor note.

Extra crunch and nutty contrasts

Toast pecans, walnuts, or almonds until fragrant, then sprinkle generously over the base for a robust crunch.
Add a streusel-like topping: ¼ cup rolled oats, 2 tablespoons brown sugar, 1 tablespoon melted butter, and a pinch of cinnamon; bake until crisp.
Sprinkle a light sea salt over the top to heighten sweetness and add a savory contrast.
Try a mix of nuts and seeds for texture variety—pepitas or pecan fragments pair nicely with the cinnamon.
