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.
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.
