    Tips and Variations

    You may think making the best sweet potato casserole your family’s ever eaten is going to be complicated or challenging. But it’s not! Here are a few tips to ensure it turns out perfectly and wows all your guests.

    • Sweetener: If you choose not to use sweetened condensed milk, feel free to use dark brown sugar, light brown sugar or maple syrup with a hearty splash of half and half or heavy cream.
    • Lighter Texture: Want to make this sweet potato casserole a little more airy? Whip an egg and add it to the casserole. This will create an lighty and fluffy bite.
    • Fresh Unavailable? Though I recommend baking or boiling fresh sweet potatoes, you could use drained, canned sweet potatoes if that’s all you can find. They will be sweeter, so sweeten slowly and taste as you go.
    • Watch Closely: Keep an eye on the dish to ensure that the marshmallow topping browns but doesn’t burn. IF it burns, scrape off the burned layer completely – including any charred bits – and apply a new, fresh layer of marshmallows, and toast again.
    • Baked vs Boiled: Either option works, but baked sweet potatoes tend to be more moist than boiled sweet potatoes. Baked sweet potatoes also happen to be easier to prepare since you don’t have to peel them!

    Can You Prepare Sweet Potato Casserole Ahead?

    Absolutely! This is a great holiday casserole to prepare a day or two in advance.

    Make Ahead: Prepare the entire sweet potato casserole up to 48 hours in advance, but hold off on adding the marshmallows. Instead, wrap the dish tightly with foil and store in the fridge. When you’re getting ready to serve, remove it from fridge and let the casserole rest on the counter for at least 30 minutes. Pop it into the oven with the foil on and cook for 20 minutes. Remove the foil, add the marshmallows, and return to the oven until marshmallows are toasted.

    Get A Head Start

    Even if you’re not prepping the entire casserole ahead of time, sweet potatoes can be cooked up to 4 days in advance with no compromise in taste or texture. Cool cooked sweet potatoes to room temperature and store in the fridge in an airtight container.

    How To Store Leftovers

    This sweet potato casserole with marshmallows is best served fresh, but leftovers can be stored to be enjoyed another day.

    • Fridge: Store leftovers for up to 5 days in the refrigerator by tightly wrapping the casserole dish in plastic wrap. If you only have a few servings left, you can place them in an airtight container instead.
    • Reheat: When you reheat it, the marshmallows will likely evaporate a little. It will still taste delicious, but will look a little different. To reheat, replace plastic wrap with foil and bake in 350°F oven until warm. Or microwave individual servings in a microwave safe dish.

Remove foil, add the marshmallows, and return to the oven until marshmallows are toasted.

    Store Leftovers: Store leftovers for up to 5 days in the refrigerator by tightly wrapping the casserole dish in plastic wrap or place in an airtight container.

    Baked vs Boiled: Either option works, but baked sweet potatoes tend to be more moist than boiled and then mashed sweet potatoes. Baked sweet potatoes also happen to be easier to prepare since you don’t have to peel the potatoes.

    Sweetener: If you choose not to use sweetened condensed milk, feel free to use dark brown sugar, light brown sugar or maple syrup with a hearty splash of half and half or heavy cream.
