How to Make This Two Way Sweet Potato Casserole
To make this Sweet Potato Casserole, simply:
- Prep sweet potatoes: Peel and cut sweet potatoes into large cubes. Place into a large pot of water and bring to a boil. Boil for 15 minutes or until sweet potatoes are very fork tender. Drain and allow them to cool for about 10 minutes before mashing.
- Make the filling: In the bowl of an electric mixer fitted with the paddle attachment, combine the mashed sweet potatoes, sugar, salt, vanilla, eggs, and butter. Mix on low-medium speed until the texture is smooth. Pour mixture into a lightly greased 9×14 baking dish.
- Make the brown sugar topping: In a small bowl, whisk together brown sugar, flour, nuts, and butter. Sprinkle mixture evenly over top of half of the sweet potatoes, leaving the other half bare. Bake at 350 degrees for 35 minutes.
- Add marshmallow topping: Remove from oven and place the halved marshmallows on the bare half of the sweet potatoes. Bake for 5 more minutes so the marshmallows can get slightly melted and browned on top.
Mashing the sweet potatoes: I prefer placing them into a blender and pulsing until they are a smooth consistency. You can also mash them with a potato masher, bottom of a cup, or large fork depending on what you have on hand! It’s okay if they aren’t perfectly smooth yet as you will be mixing them more throughout the recipe.
Make ahead: This sweet potato casserole can definitely be made before hand and refrigerated overnight. Simply prepare the filling according to recipe instructions, but it’s best to hold off on baking it with the toppings until the day you serve it. When ready to serve, take out of the fridge and let come to room temperature for about 15 minutes. Bake at 350 degrees for 35 minutes with the brown sugar topping on half, then adding the marshmallow halves and baking for 5 more minutes as the recipe instructions call for.
To store: Once fully cool, wrap tightly in plastic wrap or an airtight container and store in the fridge for 3 to 5 days.
