Sweet Potatoes and Black Walnuts: A Taste of Southern Comfort

The scent of sweet potatoes baking always transports me back to my grandmother’s kitchen in rural Tennessee. I remember the warmth radiating from the old wood-burning stove, the rhythmic clatter of her mixing bowl, and the earthy aroma that filled the air as she prepared her famous sweet potato dish. But it wasn’t just any sweet potato dish. It was her secret recipe, infused with the distinctive, almost wild flavor of black walnuts – a taste that truly captured the essence of the South. To this day, I recreate her recipe, and every bite is a comforting trip back to those cherished childhood moments.

Recipe Overview

Prep Time: 20 minutes
Cook Time: 20-30 minutes
Total Time: 40-50 minutes
Servings: 6-8
Yield: 1 baking dish
Dietary Type: Vegetarian

Ingredients

6 large sweet potatoes
1 cup milk, hot
3 tablespoons butter
2 tablespoons butter, melted
1/2 cup sugar
1/2 cup black walnuts
1 pinch salt

Equipment Needed

Large pot
Potato masher or electric mixer
Greased baking dish (approximately 9×13 inches)

Instructions

Begin by preparing the sweet potatoes. Peel them thoroughly.
Place the peeled sweet potatoes in a large pot and cover them with water. Bring the water to a boil over high heat.
Once boiling, reduce the heat to medium and continue to boil the sweet potatoes until they are tender and easily pierced with a fork. This should take approximately 15-20 minutes, depending on the size of the potatoes.
Once the sweet potatoes are cooked, carefully drain the water from the pot.
Return the sweet potatoes to the pot and use a potato masher or an electric mixer to mash them until smooth.
While the sweet potatoes are still hot, add the 1 cup of hot milk, 3 tablespoons of butter, and 1/2 cup of sugar.
Mix all ingredients together until well combined and the mixture is smooth and creamy.
Next, add the 1/2 cup of black walnuts and 1 pinch of salt to the sweet potato mixture.
Mix again, ensuring the black walnuts are evenly distributed throughout the mixture.
Grease a baking dish generously with butter or cooking spray.
Pour the sweet potato mixture into the prepared baking dish, spreading it evenly.
Melt the remaining 2 tablespoons of butter.
Pour the melted butter evenly over the top of the sweet potato mixture in the baking dish.
Bake in a preheated oven at 350 degrees Fahrenheit (175 degrees Celsius) for 20 to 30 minutes, or until the top is lightly golden brown and the mixture is heated through.
Remove the baking dish from the oven and let it cool slightly before serving.

Expert Tips & Tricks

Choose the right sweet potatoes: Look for sweet potatoes with smooth, unblemished skin. Smaller to medium-sized sweet potatoes tend to have a sweeter flavor and more consistent texture.
Don’t overcook the sweet potatoes: Overcooked sweet potatoes can become watery and lose their flavor. Cook them just until they are tender enough to pierce easily with a fork.
Warm the milk: Heating the milk before adding it to the sweet potatoes helps to create a smoother, creamier texture. It also prevents the mixture from cooling down too quickly.
Toast the black walnuts: Toasting the black walnuts before adding them to the sweet potato mixture enhances their flavor and aroma. Simply spread the walnuts on a baking sheet and bake them in a preheated oven at 350 degrees Fahrenheit (175 degrees Celsius) for 5-7 minutes, or until they are lightly toasted and fragrant. Be careful not to burn them.
Adjust the sweetness: Taste the sweet potato mixture before baking and adjust the amount of sugar to your liking.
Make ahead: This dish can be prepared ahead of time and baked just before serving. Simply prepare the sweet potato mixture, pour it into the baking dish, and cover it tightly with plastic wrap. Store it in the refrigerator for up to 24 hours. When ready to bake, remove the plastic wrap and bake as directed.
