Quick ‘n Easy Southern Sweet Potato Casserole (with Marshmallows!)

My quick ‘n easy southern sweet potato casserole was created in less than 20 minutes, and thanks to my collaboration with Izea and my local Dollar General store, where I purchased all of the ingredients needed to make the recipe, it cost me less than fifty pennies per serving to create.

This is truly a #DGHoliday recipe! This post is brought to you by Dollar General. All opinions are 100% mine.

Quick 'n Easy Southern Sweet Potato Casserole (with Marshmallows!) - get the recipe on ItsYummi.com I’m really picky about what goes into my holiday recipes, especially the ones that are iconic, like this southern sweet potato casserole with marshmallows.  It’s the mallows, ya’ll!

Incidentally, if you’ve never heard a girl from the Midwest speak with a southern drawl, amuse yourself sometime and request it. It’s the funniest danged thing ya’ll will ever hear.

What I mean to say is that the sweet potato casserole that I eat on Thanksgiving must have marshmallows in it.  Otherwise, it’s just plain and simple mashed sweet potatoes, which are delicious in their own right, but they’re not iconic, and Thanksgiving recipes in my house require a little bit of nostalgic charm.

What I love the most about this particular recipe is how budget friendly it is. Because I purchased absolutely every ingredient I needed at Dollar General, this delicious side dish cost me less than fifty cents per serving.  That’s crazy awesome, especially since the price of sugar has risen so much in the past year.

Truthfully, I’ve been into dollar stores a million times before, but I’ve never really spent much time browsing around the food aisles. I usually just run in for a birthday card, holiday decorations, or some cleaning supplies, and maybe I’ll stop over at the candy aisle and grab something for the movie theater, but very rarely do I think about buying groceries there.

I was really surprised at how well stocked my local Dollar General is, and I honestly had no idea that they have a refrigerated and freezer case with dairy products like milk and eggs and frozen foods like pizza and even frozen shrimp. How did I miss that before?!  Talk about convenient!  Now that I know, when I stop in for holiday decorations this year, I plan to buy everything I need to put together more of my shrimp and corn salsa shooters appetizer for our tree decorating party.

Assembling this sweet potato casserole is super quick ‘n easy. All you need to do is drain and mash the sweet potatoes, mix in the rest of the ingredients, top it off with mini marshmallows and put it into the oven to toast those babies up.  It doesn’t get any easier and it definitely meets the It’s Yummi test for taste!

    WOW I never would have thought to add marshmallows to a casserole before! You definitely have got me curious to know what this tastes like.. think I have to recreate the recipe!

      Chef Becca October 20, 2014 (7:23 am)

      I hope you have a chance to try the recipe sometime, Thalia. The sweetness of the marshmallows pairs wonderfully with the sweet potatoes, making the casserole a cross between a side dish and a dessert! It’s a little bite of Heaven 🙂

    Ahhhh yoou and I make this almost identical! I make this and everyone eats it up. The only difference is I use fresh sweet potatoes and cook them up myself rather than canned – to me it just tastes better . I will also go to yams and there is a sllightly diifferent flavor to it. So good its like a dessert!

    • comment-avatar
      Chef Becca October 19, 2014 (6:15 am)

      Ellen, it’s a delicious side dish for sure. On busy days, the convenience of canned yams is nice, but I agree with you that fresh sweet potatoes are always the best!

      I often wonder about my overseas friends like you, Stacy. Do dollar stores exist in Dubai?

        We don’t have dollar stores but we do have the Japanese chain, Daiso, which is close. It doesn’t have any food though.

    I love buying stuff like that at Dollar General! Of course, when I go I have to take Sophie with me because she enjoys exploring every aisle. It’s definitely a lower cost one-stop-shop1

      I think “one-stop shop” is a perfect way to describe Dollar General!

    I make a version of this but I love the changes you made and need to try your version.
    I sometimes mix mini mashmallows into the recipe too (shhhh, don’t tell).

    This recipe reminds me of my mother and her southern cooking recipes. Can’t wait to try it out for her.

      Chef Becca October 14, 2014 (3:45 am)

      Meagan, when I was young, I used to wonder why it was the older generation’s southern-style recipes that got the most attention on holidays. Now that I’m the older one and I see how comforting and perfectly easy they are to prepare, like this sweet potato casserole, it all makes perfect sense! I hope this recipe makes your mom proud 🙂

    So classic for Thanksgiving. Growing up we always had to have marshmallows on our sweet potatoes to. And by we, I mean my dad – because I wasn’t a fan back then. Now though, that is a different story! Great looking recipe.

    Woohoo! I request Chef Becca to speak in a Southern drawl for the next 2 weeks straight. Is that doable? In return, I’ll speak in a Midwestern drawl…even though I don’t really know what that is. Haha. This casserole looks delicious, btw! 🙂

    • comment-avatar
      Chef Becca October 12, 2014 (3:06 pm)

      I can’t even imagine how scary it will be for my neighbors to have to suffer through 2 weeks of me speaking that slowly, but to hear you speak Wisconsinese for even an hour should be enough entertainment for the entire year! 😀
