There’s a moment, just as this casserole comes out of the oven, that takes me right back to my grandmother’s kitchen.

It’s that golden-brown, marshmallow-topped dish that consistently steals the show at any gathering, nestled proudly beside the turkey or ham. I’ve always believed the true magic lies in its beautiful duality—is it a side dish or a dessert? We can argue about that later! For now, let’s focus on creating the best sweet potato casserole, one that’s never runny and always utterly memorable. It’s a classic sweet potato casserole that feels both timeless and like a warm hug on a plate. If you’re looking for a slightly different take, my maple-infused version is a lovely twist on this tradition.

Step-by-Step Instructions

Step 1: Prep Your Dish

Preheat your oven to 350°F (175°C) and grease a 9×13 inch baking dish. This ensures your casserole won’t stick and makes for much easier cleanup later.

Step 2: Make the Base

In a large bowl, combine the mashed sweet potatoes, granulated sugar, eggs, milk, 1/2 cup melted butter, vanilla extract, and salt. Mix well until the mixture is smooth and beautifully combined.

Step 3: Assemble the Base

Pour the sweet potato mixture into your prepared baking dish. Use a spatula to spread it out into a lovely, even layer.

Step 4: Create the Topping

In a separate medium bowl, make the iconic sweet potato casserole topping by mixing the brown sugar, flour, 1/3 cup melted butter, and chopped pecans. Mix until the texture is delightfully crumbly.

Step 5: Add the Topping

Sprinkle the pecan streusel topping evenly over the sweet potato mixture. Don’t be shy—cover every inch!

Step 6: First Bake

Bake for 25-30 minutes, or until the filling is set and the topping is a perfect, golden brown.

Step 7: Toast the Marshmallows

Remove from oven and top with mini marshmallows. Return to the oven for 2-3 glorious minutes until marshmallows are lightly toasted and puffy.

Step 8: Rest and Serve

Let the casserole cool for 10 minutes before serving warm. This allows everything to set just right.
