Brown Sugar Glazed Sweet Potatoes with Marshmallow & Pecan Topping

Here is a simple, yet slightly decadent sweet potato recipe, which is perfect for the holidays. The scent of aromatic spices and toasty pecans warm up the kitchen as fresh sweet potatoes bake in a brown sugar glaze. Even if you aren’t a fan of sweet potatoes, this recipe is hard to resist. And best of all, it is easy to make. The most difficult part of this recipe is peeling and dicing the sweet potatoes. I like to share sweet potato recipes in the autumn; since Louisiana-harvested sweet potatoes are so readily available. Plus, they are quite nutritious. This year I am sharing a holiday recipe which deviates a bit from the nutritional angle — but this recipe is so very good — serve it for a special occasion.

Since sweet potatoes are a Louisiana agricultural product, I feature recipes for this nutritious root vegetable in the autumn when they are harvested. Surprisingly, I have found many ways to add sweet potatoes to recipes. My past posted recipes have ranged from soups, to Brazilian sweet potato bread to Cajun sweet potato fries to Ruth Chris Restaurant’s sweet potato casserole. This recipe, “Brown Sugar Glazed Sweet Potatoes with Marshmallow & Pecan Topping,” might be one of my favorites. It is very easy to make and I love the marshmallow topping. Woops, looks like I burnt the marshmallows. Don’t do that.

I describe this recipe as a little decedent. The brown sugar glaze adds a sweet touch to the sweet potato casserole. Plus, you are eating marshmallows at the dinner table; not for dessert. Yum. But the aromatic spices and marshmallow-pecan topping help tone down the sweet potato flavor for those of us which are hesitant about eating sweet potatoes. And the toasted pecans add crunch and flavor. I always use fresh sweet potatoes for casserole-type recipes rather than canned sweet potatoes or yams. Fresh sweet potatoes have a milder flavor than the canned ones. And I don’t want to skip the pleasure of peeling and dicing three sweet potatoes.


I scaled down the quantities of this recipe from my original source to make a smaller dish. I used enough sweet potatoes to fill a 9″ round Pyrex or ceramic casserole dish. This might help avoid too many leftovers at the Thanksgiving dinner. There is always so much food at our extended family’s Thanksgiving dinner that you really only need a “taste” of each dish.

Since this sweet potato casserole is baked and served in the same dish, I picked an attractive casserole dish for the recipe. Just make sure that the dish you use can tolerate a 500 degree oven which is needed to toast the marshmallows.

Here are the ingredients for this recipe. I used cinnamon, ginger and nutmeg for aromatic spices. Brown sugar and margarine make the glaze. Each of these sweet potatoes weigh about 8 ounces each; I used only three of them to make this casserole dish.

To make this recipe, peel and dice the sweet potatoes. I cut the chunks into small 1/2″ to 3/4″ cubes. Add these raw sweet potato cubes to the casserole dish. In a small saucepan, melt the margarine and brown sugar. Add the spices and salt.

Pour the syrup over the sweet potatoes and mix to combine.

Cover very tightly with aluminum foil and bake in a 350 degree oven for 30 minutes until the sweet potato cubes are tender. Remove the aluminum foil, carefully gently toss to combine (the sweet potatoes will be hot, so be careful). Bake 15 minutes longer to evaporate off some of the liquid in the bottom of the casserole dish. If some of the cubes become mashed when you are tossing them, that’s okay.

The topping consists of miniature marshmallows and chopped pecans. How many marshmallows? I used 1/2 the bag; you really only need enough to cover the casserole dish in one layer — use 3 cups or about 1/3 of the bag. I got carried away.

Don’t skip the pecans. Their crunch and aromatic scent really enhance this dish.

Sprinkle the marshmallows over the top of the casserole dish and then add the pecans.

Turn the oven up to 500 degrees. Roast the casserole dish for only 3 minutes until the marshmallows brown and the pecan pieces begin to give an aromatic scent to the kitchen. Check carefully; the marshmallows brown quickly. Some of mine burnt.

Ready to serve. Who minds eating dessert during the main meal. I think my relatives will like this dish. Let’s be festive this holiday season. Enjoy!

  1. It must be the week for sweet potato recipes! Haha…I posted one yesterday, too.

    Marshmallows are not my thing, but I like that this recipe seems to come together pretty easily. I also love the inclusion of crunchy pecans. Are they also a Louisiana product? I know they grow well in Georgia, so I imagine maybe there as well. I hope your family members have a wonderful Thanksgiving, and that every dish on your table is a big hit! 🙂

    • Hello, I love burnt s’mores, so the over-done marshmallows are just right for me. Yes, Louisiana is a big pecan producer so I like to use pecans in recipes where ever possible. The crunch of the pecans in this recipe really sets it apart from other recipes — I once took care of the owner of one of these producers in the hospital — he passed out bags of pecans to the nurses and we all loved him! Hey, one can never have too many sweet potato recipes. Yours looks mighty tasty, too. All the adult grandkids are cooking Thanksgiving dishes this year, so I mainly get to watch and eat — (and bring this dish). What a treat. Hope you have a great Thanksgiving, too. Now, I’m off to work on buttermilk fried chicken for football bowl games — there is always room for more of those recipes, too!

  2. How nice that you get to relax and enjoy this year! I will look forward to your buttermilk fried chicken recipe. I love eating it but never seem to get it right myself at home. It’s the frying that trips me up, so I’ll see what I learn from your recipe. 🙂

    Oh, and I love the burnt marshmallows for s’mores too. Just not a fan of them on sweet potatoes, probably because my Thanksgiving table already has so many rich foods. Today, wordpress reader teased me with someone else’s recipe for a sweet potato casserole old fashioned cocktail. It had a sweet potato syrup and torched marshmallows on top! I do love a theme. Haha

      • Oh my gosh, it took me forever to find that cocktail recipe again! And how interesting is this??– it is offered by a Louisiana-based company! I knew the name sounded familiar (El Guapo), so I checked my own bar. Sure enough, I have their chicory-pecan bitters and enjoy them. Anywhere, here’s the link. I might have to order their sweet potato syrup and give it a try! 🙂

      • Crazy! Yes, looks like the establishment is located in New Orleans and that they sell their product at a spice store here in town and a couple of liquor stores here and in NO suburb. I’ll have to check it out and know exactly where to serve this sweet potato drink. Their bitters and syrups are so creative — it will be hard to decide on just one! Thanks for the tip.

      • And did I mention, that the Baton Rouge location is right down the block from where I live? I’ll have to make a field trip — hum, for business — there later this afternoon.

      • Hey Maylee, I found the cocktail recipe, but my reply may have been filtered in spam because I included the link. I hope you get a chance to check it out. Cheers!
