Inside-out sweet potatoes are, quite simply, the best thing to happen to Thanksgiving since sweet potato casserole.
Inside-out sweet potatoes are crazily clever little bombs of sweet, gooey deliciousness that are perhaps better suited to no other day of the year than Thanksgiving. They’re essentially an irreverent and savvily deconstructed approach to everyone’s favorite iconic sweet potato casserole. Not only are the gooey, crunchy, buttery little bursts of melted marshmallow irresistible to children, they’re also ridiculously tempting for adults. Never fails to impress.

How To Make These Inside-Out Sweet Potatoes When You're Also Juggling Everything Else On Thanksgiving
Thanksgiving may not seem the ideal time to stand at the stove and deep-fry sweet potato-smothered marshmallows one by one. We realize that. Yet cookbook author Martha Hall Foose suggests a simple and savvy make-ahead strategy. She bakes and mashes the sweet potatoes early in the day (or even the night before) and then slathers the sweetly spicy sweet potato goo all over the marshmallows, plops them on a baking sheet, and refrigerates them for up to several hours. This means you can forget about them until after you take the turkey out of the oven and are waiting impatiently for it to rest, which is when you roll the sweet potatoes in the cornflake crumbs and get to frying. We’d even go so far as to suggest you snag a guest, hand him or her an apron, and ask him to do the honors. See how simple that can be?
Inside-Out Sweet Potatoes
Special Equipment: Deep-fry or candy or instant-read thermometer
Ingredients
- 6 sweet potatoes, unpeeled
- 1 large egg
- 4 tablespoons (1/2 stick) unsalted butter (2 oz), melted
- 1/3 cup packed dark brown sugar
- 1/2 teaspoon ground cinnamon
- 1/4 teaspoon ground nutmeg
- Pinch ground cloves
- 1/4 teaspoon baking powder
- 1 tablespoon unbleached all-purpose flour
- 1 tablespoon orange juice
- 1 tablespoon bourbon, sherry, or vanilla extract
- 1 cup crushed cornflakes
- 8 large or jumbo marshmallows
- Canola oil, for frying (1 1/2 cups)
Directions
- 1. Preheat the oven to 375°F (190°C).
- 2. Grab a fork and pierce each sweet potato several times all over. Place the sweet potatoes on a rimmed baking sheet lined with parchment paper or a Silpat. Bake until the sweet potatoes are tender and easily pierced with the tip of a sharp knife, about 40 minutes, depending on the size of the sweet potatoes. Allow the sweet potatoes to cool in their skins. When cool enough to handle, use a knife to halve the potatoes lengthwise and then scoop out the insides from the skins into a bowl. Mash the sweet potatoes with a fork or potato masher until smooth.
- 3. Combine the mashed sweet potatoes with the butter, brown sugar, cinnamon, nutmeg, cloves, baking powder, flour, orange juice, and bourbon, sherry, or vanilla extract.
- 4. Place the crushed cornflakes in a shallow dish or pie plate. Beat the egg with 1 teaspoon water in a small bowl.
- 5. Working with your hands, smother each marshmallow with some of the sweet potato mixture, forming a ball. If the sweet potato mixture seems too soft to hold its shape, stir in some of the cornflake crumbs to thicken it. (You can cover and refrigerate the sweet potato-smothered marshmallows for up to 24 hours.) Dip each ball in the egg and then roll it in the crumbs. Refrigerate just until the oil is hot.
- 6. Heat the oil in a 2-quart saucepan over medium-high heat until it registers 375°F (190°C) on a deep-fry or candy or instant-read thermometer. Place a wire rack over a rimmed baking sheet. Preheat the oven to 200°F (93°C).
- 7. Fry the inside-out sweet potatoes a couple at a time, turning as needed, until lightly browned on all sides, 3 to 4 minutes total. Use a slotted spoon to transfer them to the wire rack and transfer the entire baking sheet and wire rack to the oven to keep the inside-out sweet potatoes warm while you’re frying the rest. Serve warm.
Baked Inside-Out Sweet Potatoes Variation
- If you have the oven space on Thanksgiving, you can skip the time-consuming deep-frying and bake these little lovelies instead. [Editor’s Note: We know, we know, everything is better fried. But we have this on good authority—actually, it’s from cookbook author Martha Hall Foose, who developed this recipe herself.] Simply follow steps 1 through 3 per the recipe above and then preheat the oven to 375°F (190°C). Line a baking sheet with Silpat or parchment paper and generously spray the inside-out sweet potatoes with nonstick cooking spray. Bake until browned.

This is brilliant. Love it.
I can’t wait to make this for Thanksgiving, amazing!
Brilliant concept, isn’t it?! We’ll be expecting a report, Deb. Happy Turkey Day.
Can you make these one day ahead and freeze?
Much as I’d like to say yes, I wouldn’t, Becky. I think the moisture content of foods tends to get slightly wacky after freezing, and since you’ll be deep-frying these, you don’t want extra spattering or sogginess. Especially not as you’re juggling everything for the Thanksgiving table. Although take a look at the note prior to the recipe, it does offer some advice for making them partly in advance. Every little bit helps. And don’t be shy about asking someone else for help in the kitchen and give them a specific task to accomplish.
I have to try this! This looks delicious.
‘Tis, Tara. ‘Tis.
Everything I have tried from Martha’s book Screen Doors and Sweet Tea, have been nothing shy of Southern satisfaction! Bon appetit!
We couldn’t agree more, Sheila. Martha and her book are true Southern treasures.
I am running out for some marshmallows right now! What a great idea!
Hah! Lovely to hear you’re as head over heels for this recipe as we are, Alan!
I would really, really rather bake them…how long do you suggest?
Hi Kathy, I wish that i could give you some specific guidance for baking them, but our testers only tested them as written, fried. If you do try and eliminate the frying step, please let us know how they turn out. It could be a great help to other readers.
My family has made these for years, baked. Since the potatoes will be cooked already, you really just need to melt the marshmallow and crisp up the corn flakes, adding some butter on top of the balls just before baking them really helps the browning part. Good luck! These are my families secret holiday treat.
Faith, so glad you like these and that they’re a family favorite. Happy Thanksgiving!
Kathy, we’re going to reach out to the author and see if we can get a definitive answer.
Thank you! I would love to make these for Thanksgiving
I like the sound of these! Having a small party for Thanksgiving we don’t do all of the traditional sides in one day. With leftover turkey for the days that follow, we are then able to showcase and focus on the remaining sides. With this plan think of the fun we’ll have with this recipe. I can’t wait!!
And, Penny, I can’t wait to hear what you think!
I just finished making this for the first time. I was trying to make a test batch, to see what they’re like, before taking them to thanksgiving dinner. It’s a really good idea for something you can make ahead. I decided to bake them, not fry, it took about 8-10 minutes, but my oven light doesn’t work so I was opening the door every couple minutes after 5. My only problem was that the “recipe testers” must’ve been using some little sweet potatoes. I tried to halve the recipe so I only used 3, what I thought were normal sized, and still ended up using 8 marshmallows so in essence all I really did was halve the flavor. They were still good just not as flavorful as they should be. I think for thanksgiving I’m gonna use my 6 sweet potatoes and double everything else, fingers crossed.
Deanna, that makes perfect sense. Sweet potatoes vary so incredibly dramatically in size, don’t they? We wish that when we’d tested the recipe we’d asked testers to weigh their potatoes. If you happen to have a scale, kindly let us know what you end up with. Otherwise, one of these days we’ll retest this and add the weight so that readers, like you, have a better barometer. We SO appreciate you taking the time to share your experience and thoughts. Thank you! And happy Thanksgiving!
I would like to use this recipe for a fondue party. Do you think it would work. I think I should pre skewer them. Would wooden skewers work for deep frying?
Mary, I’m not they would work. They’re large, and I don’t believe they would hold up on a skewer. They’d plop right off into the oil.
