Thanksgiving is right around the corner, and while it means we get to spend a day with our family and loved ones, embracing the things that fill our hearts and make us most grateful, it’s also a massive food holiday. It can easily become a stressful day with pans and pots flying in every direction and a never-ending amount of oven and cleanup time.

But I’m all about simplifying Thanksgiving by making some dishes ahead of time and allowing myself a little space to relax and enjoy the day when it arrives, and this sweet potato casserole lets me do just that. You will love enjoying this warming, hearty, sweet, and comforting dish around your kitchen table with your family and friends.

Recipe FAQs

Can you freeze sweet potato casserole?

Yes! You can freeze leftovers for a chilly day when you want something sweet and warming, make sure you let them cool completely, store them in an airtight container, and freeze them for up to three months.

Can sweet potato casserole be made ahead?

To make this dish ahead of time, prepare through step 8 of the recipe instructions (get the sweet potato layer ready and put it in the pan). Make the streusel, and keep it separate. Store both parts of the dish covered in the fridge until you are ready to bake, up to 2 days in advance. Let the dish come to room temperature before baking, add the topping, and bake as directed.

What goes with sweet potato casserole?

Turkey, of course! But really, anything goes well with sweet potato casserole. It’s sweet yet pairs nicely with rich and savory meat, such as ham or chicken.

Expert Tips

  • So Easy: Sweet potato casserole is seriously impossible to mess up—that’s the beauty of pretty much all casseroles! Bake 350 for about 35 minutes, until the streusel topping looks crispy.
  • Reheating: To reheat, thaw in the fridge overnight and bake at 350 until heated, about 15 to 20 minutes.
  • Or Bake From Cold: You can bake the cold sweet potatoes for 15 minutes, add the topping, and bake for the rest of the 35 minutes.

How to Fix Runny Sweet Potato Casserole

If your casserole turned a bit on the runny side, it’s likely due to either a bit too much milk or not quite hitting the 4 pounds of sweet potatoes for the needed mash to soak up the liquid. But no worries, it’s easy to fix!

To fix a runny sweet potato casserole, I suggest adding a thickener. Any of these thickening tips should do the trick:

    • Mix in 1-2 tablespoons of cornstarch or flour
    • Stir in 1/4 cup instant mashed potato flakes
    • Add more mashed sweet potatoes

    You can also bake it a bit longer, about 10-15 minutes extra, leaving it uncovered. Letting it rest 10-15 minutes before serving will also give it time to finish setting up.

    How to Reheat Sweet Potato Casserole

    If you’ve made the casserole ahead of time, finish getting it ready for the table by letting the dish come to room temperature first. Then add the topping and bake it according to the recipe.

    For leftover casserole, it can be reheated in the microwave or oven. It will only need to be heated until warmed through since it has already been cooked completely.

    This casserole may be my family’s favorite way to eat sweet potatoes, but of course I like to mix it up and serve them in other ways, too!

    Instructions 

    • Prepare the sweet potatoes by scrubbing them clean with water and a scrub brush.
    • Trim 1/2 inch off both ends of each sweet potato, and place them on a wire rack set inside of a rimmed baking sheet.
    • Bake at 400 degrees F for 40 to 50 minutes or until very tender. This step can be done 1 to 2 days in advance to save time on cooking day.
    • Let the sweet potatoes cool enough to handle. Cut each in half and slip their skins off.
    • Place the sweet potatoes in a large bowl or in the bowl of your stand mixer. Beat on high for 1 minute, stopping to scrap down the sides as needed.
    • Add the salt, sugar, milk, vanilla, and butter, and beat until the mixture is very smooth.
    • Add the eggs and beat until light, about 2 minutes.
    • Place the sweet potato mixture in the bottom of a greased 9×13-inch baking dish.
    • To make the streusel topping, mix the brown sugar, pecans, flour, cinnamon, and melted butter in a small bowl until it comes together like a loose dough.
    • Sprinkle the topping over the whipped sweet potatoes in the pan, forming an even layer.
    • Bake at 350 degrees F for 35 minutes or until the topping has gotten a bit crispy.
    • Serve hot or warm.
