Sweet Potato Spoonbread

Get ready to fall head over heels for this Southern comfort classic that’s about to become your new obsession!

Sweet potato spoonbread is the perfect marriage of creamy, custardy texture and rich, earthy sweetness that’ll have everyone at your table asking for seconds (and thirds).

This isn’t your average cornbread – it’s a sophisticated, spoon-worthy creation that combines the natural sweetness of perfectly roasted sweet potatoes with stone-ground cornmeal and a hint of warming spices.

The magic happens when fluffy beaten egg whites get folded into the batter, creating an incredibly light and airy texture that’s somewhere between a soufflé and traditional cornbread.

What makes this recipe absolutely irresistible is the complex flavor profile that develops from roasting the sweet potatoes directly on the oven rack until they’re caramelized and tender, then combining them with buttermilk’s tangy richness and a carefully balanced blend of cumin, white pepper, cloves, and just a whisper of cayenne.

The result is a golden, risen masterpiece that’s crispy on top and impossibly creamy inside.

Whether you’re serving it as a show-stopping side dish for holiday gatherings or making it the star of a cozy weekend brunch, this spoonbread delivers restaurant-quality results that’ll have your guests convinced you’re a culinary genius.

Ingredients

For the Sweet Potato Base

1 pound sweet potatoes
1½ cups buttermilk
1½ tablespoons mild honey
5 large egg whites (at room temperature)

For the Cornmeal Mixture

2¼ cups stone-ground yellow cornmeal
1½ tablespoons sugar
1½ teaspoons salt
1½ teaspoons baking soda
1½ tablespoons unsalted butter (at room temperature)
3 cups boiling water

For the Spice Blend

¼ teaspoon ground cumin
¼ teaspoon freshly ground white pepper
⅛ teaspoon ground cloves
⅛ teaspoon cayenne pepper

Instructions

Prepare the Sweet Potatoes

1 Preheat the oven to 375°F (190°C). Using a fork, pierce the sweet potatoes all over to prevent bursting during roasting. Place them directly on the oven rack for even heat circulation.
2 Bake the sweet potatoes for 1 hour, or until they yield easily to gentle pressure and are completely tender throughout. Let them cool slightly until safe to handle.
3 Carefully slit the skins lengthwise and scoop the flesh into a large mixing bowl. Mash until completely smooth using a potato masher or fork. You should have approximately 1¼ cups of mashed sweet potatoes. Increase the oven temperature to 425°F (220°C).

Prepare the Baking Dish and Cornmeal Base

4 Lightly butter a shallow 2-quart glass or ceramic baking dish, ensuring all surfaces are coated. Dust the buttered dish with cornmeal, tapping out any excess – this creates a beautiful crust and prevents sticking.
5 In another large bowl, whisk together the stone-ground cornmeal, sugar, salt, and baking soda until evenly combined. The stone-ground cornmeal provides superior texture and flavor compared to regular cornmeal.
6 Melt the butter in the 3 cups of boiling water, stirring until completely dissolved. Gradually stir this butter-water mixture into the dry cornmeal ingredients, whisking constantly to prevent lumps. Let this mixture cool slightly to prevent scrambling the eggs later.

Combine and Finish the Batter

7 Using an electric mixer on medium speed, beat the buttermilk, honey, cumin, white pepper, cloves, and cayenne into the mashed sweet potatoes until the mixture is completely smooth and well combined. The spices should be evenly distributed throughout.
8 At medium speed, gradually beat the cooled cornmeal mixture into the sweet potato mixture until thoroughly incorporated. The batter should be smooth but thick.
9 In a clean stainless steel bowl using clean beaters (any residual fat will prevent proper whipping), beat the room-temperature egg whites until they form stiff peaks but are not dry or grainy. Properly beaten whites should hold their shape when the beaters are lifted.
10 Using a large spoon or spatula, gently fold the beaten egg whites into the sweet potato mixture in three additions. Fold just until no white streaks remain – overmixing will deflate the whites and result in a dense spoonbread.

Bake and Serve

11 Pour the batter into the prepared baking dish, spreading it evenly. Bake for approximately 40 minutes, or until the top is golden brown, the spoonbread has risen significantly, and a toothpick inserted in the center comes out clean or with just a few moist crumbs.
12 Serve the sweet potato spoonbread warm or at room temperature. It’s delicious either way and can be reheated if made earlier in the day.

Recommended Equipment and Kitchen Tools

Recommended Tools (for best results):

Electric mixer – Essential for properly incorporating the buttermilk mixture and achieving perfectly beaten egg whites. A stand mixer works beautifully, but a hand mixer will do the job.
Large mixing bowls – You’ll need at least three bowls for this recipe, including one stainless steel bowl specifically for whipping egg whites to prevent any interference from residual fats.
2-quart shallow baking dish – Glass or ceramic works best for even heat distribution and beautiful presentation. The shallow depth ensures proper cooking throughout.

Helpful Upgrades:

Kitchen scale – For the most accurate measurements, especially with the stone-ground cornmeal, which can vary in density between brands.
Silicone spatula – Perfect for gently folding the egg whites without deflating them, ensuring your spoonbread achieves maximum height and fluffiness.

It’s ideal for potluck dinners since it travels well and appeals to diverse palates, and makes an impressive dinner party side that guests will remember long after the meal ends.

Pro Tips and Troubleshooting

Professional Techniques:
Always roast sweet potatoes directly on the oven rack rather than wrapping in foil – this concentrates their natural sugars and prevents wateriness that can make your spoonbread soggy. When folding in egg whites, use a gentle cutting and folding motion rather than stirring, and stop as soon as no white streaks remain. Overmixing deflates the whites and results in dense, heavy spoonbread. For the fluffiest results, ensure your egg whites are at room temperature before beating – they’ll whip to greater volume than cold eggs.

Common Mistakes and Solutions:
If your spoonbread turns out dense, you likely overmixed the egg whites or they weren’t beaten to proper stiff peaks. Dense texture can also result from sweet potato puree that’s too wet – always mash freshly roasted potatoes while warm and let excess moisture evaporate. If the top browns too quickly, tent with aluminum foil and continue baking until the center is set. Cracking on top usually indicates the oven temperature is too high or the dish is positioned too close to the heating element.

Storage and Make-Ahead Strategies:
This spoonbread can be made up to 8 hours ahead, wrapped tightly in aluminum foil, and reheated in a 350°F (175°C) oven for 15-20 minutes. For longer storage, refrigerate for up to 3 days and reheat individual portions in the microwave for 30-45 seconds. The texture is best when served fresh, but leftovers make excellent breakfast when topped with butter and honey. For entertaining, prepare through step 10, cover and refrigerate the batter for up to 4 hours, then bake when ready to serve.

Sweet potato spoonbread represents the very best of Southern comfort cooking – a dish that transforms simple, wholesome ingredients into something truly extraordinary. The combination of roasted sweet potatoes, stone-ground cornmeal, and carefully balanced spices creates layers of flavor that develop beautifully as the spoonbread bakes to golden perfection. Whether you’re continuing a family tradition or discovering this classic for the first time, this recipe delivers the kind of memorable, soul-satisfying results that turn ordinary meals into special occasions and create lasting food memories for everyone lucky enough to share your table.
