My Mom had a big sweet tooth.  She would stash Little Debbie’s and chocolate bars around the house trying to ensure she’d have something sweet when the cravings kicked in.  She was also very southern in her style of cooking, so you could expect a dash (or a lot) of sugar to go into most dishes including her macaroni and cheese.  And it all tasted so good.

So it’s no surprise that her famous sweet potato casserole with marshmallows is the real deal.  Yup, I’m talking brown sugar AND real butter AND marshmallows, friends.  I don’t cook with these ingredients a lot but when I do I do it RIGHT.

The Best Sweet Potato Casserole with Marshmallows

I haven’t shared this Sweet Potato Casserole with Marshmallows recipe on Running in a Skirt because I worried that it doesn’t exactly fit into the healthy mold I try to create here.  BUT I believe that you should eat and enjoy foods like this in moderation, especially when it is such a family favorite.

Making this old fashioned recipe during the holidays helps keep my Mom’s memory alive.

I believe in traditional family recipes and I believe in THIS recipe.  I know if you try it you will feel the same.

Ingredients in the Sweet Potato Casserole with Marshmallows:

  • Sweet Potatoes: I use fresh sweet potatoes as my Mom did.  Peel them and cut them into 1-inch cubes.  You can use canned but I think fresh sweet potatoes taste so much better.
  • Brown Sugar: You need the real stuff for this recipe.
  • Butter: Butter makes the potatoes rich and creamy.
  • Cinnamon: I use a heavy hand with the cinnamon to get the flavor she did.
  • Nutmeg: Nutmeg balances out the cinnamon.
  • Milk: You can use whatever type of milk you keep in the house. I usually make this with 2%.
  • Marshmallow: Mini marshmallows make this recipe so fun and southern.

Note: I occasionally will eat marshmallows, but they aren’t strictly vegetarian.  If you have concerns try these vegan marshmallows.

How to Make Southern Sweet Potato Casserole with Marshmallows:

  1. To cook the potatoes for the casserole you boil them.  Cover the potatoes with water and bring to a boil.  Simmer until tender which should be around 20 minutes.  You want them to be very soft.
  2. Preheat the oven to 400 degrees.
  3. Mash the sweet potatoes with a potato masher or mixer.
  4. Add the milk, brown sugar, butter, and spices.  Taste and add more brown sugar if desired.
  5. Smooth the potato mixture into your Grandmother’s casserole dish.  Add marshmallows to the top
  6. Bake until golden brown.

Casserole Variations & FAQ

  • My Mom’s big secret is she made her recipe and THEN added even more brown sugar until it was absolutely sinful.  If you really want to channel her sweet tooth, I suggest doing the same thing… but just for Thanksgiving.  AND maybe Christmas too…. I promise not to tell.
  • I recommend adding just a single layer of marshmallows on top to get the best cooked consistency and to keep them from melting into the casserole.
  • You can also steam your sweet potatoes or bake them whole before mashing them.  My Mom boiled them so that’s how I included it in this recipe.

 

Can Sweet Potato Casserole be made ahead of time?

YES! Make the mashed sweet potatoes and put them in a casserole dish.  It can stay in the fridge up to 48 hours before your event.  When you are ready to bake the sweet potato casserole with marshmallows ADD the marshmallow on top and bake according to the instructions.  It will need to cook a few minutes longer to get it warm.

Can you freeze sweet potato casserole?

This dish also reheats and freezes well.  To freeze the casserole make it up until the point you are going to add the marshmallows.  Cover, freeze and store until you need it.  It should keep 4-6 months.

 

Sweet Potato Casserole for 2?

This recipe can be very easily adjusted for the size of your party!  You can half it to make a small batch sweet potato casserole for a couple or small family.  When I make this for my extended family I easily double or even triple it.

It bakes easily in different size casserole dishes too.  This is a pretty easy and forgiving recipe.

    Wow, this sounds sinful! I’ve never had a traditional sweet potato casserole like this. I feel like it would be a bit too sweet for me…is it served as dessert?

    • JulieWunder November 14, 2015 at 10:39 am - Reply

      Nope! Totally a side dish. It is sweet, but balanced very well. It’s very southern 🙂

    Okay, now I really can’t wait for Thanksgiving!!
    My mom makes Martha Stewart’s mashed potatoes every year. So good. And yes, there’s heavy cream and butter involved.

      Oh! I bet that is delicious! I put just milk in mine!

    Thanks for sharing this recipe. I think my daughter and your mother had a lot in common. When I ask her what she wants to eat, she always answers, “Something sweet, please”. I love this kind of dish, their are so many variations out there, so something this simple is probably the best. I will let you know if I make it and how it turns out.

    • JulieWunder November 13, 2015 at 7:29 pm - Reply

      Please do! It’s funny how some people are programmed sweet and some savory! I just love ALL food!

    I don’t really think that sweet potato needs all the extra stuff, but I totally agree with you that indulgent food totally has its place in a healthy diet and life. And, even more important, I’m glad that you are helping to bring your mom to the Thanksgiving table. She would be so proud of you, Julie. I know she would.

    I’m glad you shared your mom’s recipe.
    I know it’s close to your heart and it’s a nice reminder for you.

  28. Jenny November 10, 2015 at 5:28 am - Reply

    Yum! Your mom had the right idea as far as I’m concerned. I like my sweet potatoes cinnamon-spice-y and basically like pie in a casserole dish. Don’t mess with a southern Thanksgiving, give me allthebutterandbrownsugar on Thursday, and we’ll have a green juice and salads on Friday. Worth it. 🙂 Thanks for sharing!
