Ingredients

5 large sweet potatoes
5 tablespoons unsalted butter, melted
3 large eggs, room temperature
2 tablespoons dark brown sugar, packed
½ teaspoon kosher salt
½ teaspoon freshly ground black pepper
1 teaspoon vanilla extract
¼ teaspoon ground nutmeg
¼ teaspoon ground cinnamon
⅛ teaspoon cayenne pepper
4 egg whites, room temperature
½ cup granulated sugar
½ teaspoon cream of tartar
1 teaspoon vanilla extract

How to Prepare Sweet Potato Casserole

Baking the Sweet Potatoes

First things first, preheat that oven to 375°F. Grab a large baking sheet and line it with parchment paper. It’s time to prepare those sweet potatoes! Prick each potato a few times with a fork. This little step allows steam to escape during baking, which is super important. Now arrange them on the baking sheet and let them bake for 70-80 minutes. You’ll know they’re done when they’re soft to the touch. Once finished, let them cool for 15-20 minutes before scooping out the insides—leave the skins behind.

Blending the Sweet Potato Mixture

Now, for that creamy goodness! In a food processor, combine the scooped sweet potatoes, eggs, dark brown sugar, kosher salt, black pepper, vanilla extract, nutmeg, cinnamon, and cayenne pepper. Blend everything until you get a smooth, luscious mixture. It should be a beautiful orange color.

Baking the Sweet Potato Base

Next, take a light spray of nonstick cooking spray and coat an 11×7-inch baking dish. Pour your sweet potato mixture into the dish and spread it evenly. Now, pop that into the oven and let it bake for 20-25 minutes. You’ll want it set and ready to meet that fluffy topping.

Preparing the Marshmallow Meringue

While your sweet potatoes are baking, let’s get going on the meringue. Start by bringing a saucepan of water to a boil, then reduce it to a simmer. In a medium bowl, whisk together the egg whites, granulated sugar, and cream of tartar. Place this bowl over the simmering water. Keep whisking! You want to dissolve the sugar completely, which should take about 3-4 minutes. Once dissolved, remove it from the heat and beat the mixture on medium-high speed until soft peaks form. If soft peaks aren’t appearing, toss in a teaspoon of sugar to help. Finally, gently fold in another teaspoon of vanilla for added flavor.

Assembly of the Casserole

When your sweet potato layer is baked to perfection, take it out of the oven. Now, we need to preheat the oven to broil. Carefully spread that beautiful marshmallow meringue over the sweet potato layer, ensuring it covers everything evenly. Place it under the broiler for a quick 30 seconds to 2 minutes or until the meringue turns a lovely golden brown. This part needs your attention since it can change quickly!

Serving Suggestions

Serve this Sweet Potato Casserole warm as a glorious side dish during holiday meals or family gatherings. It pairs well with roasted meats or a fresh, crisp salad, making it a wonderfully balanced meal that celebrates seasonal flavors.

Tips for Success

Make sure your sweet potatoes are fully cooked before scooping; undercooked potatoes can lead to a lumpy texture.
Use room temperature eggs for improved blending and increased volume in your meringue.
Keep an eye on the broiler because the meringue can brown much faster than you expect!

Variations

If you’re looking to mix things up, consider adding a nutty twist! Incorporate ½ cup of chopped pecans or walnuts into the sweet potato mixture for a delightful crunch. You can also substitute the marshmallow meringue with a store-bought topping if you’re in a hurry. Additionally, feel free to experiment with spices; adding cardamom or ginger can introduce a unique flavor profile that your family will love.

Storage Tips

Store any delicious leftovers in an airtight container in the refrigerator for up to 3 days. When you’re ready to enjoy again, simply reheat in the oven. This method helps maintain the lovely texture, while avoiding the microwave which may make it soggy.

Pairing Ideas

This Sweet Potato Casserole pairs beautifully with glazed ham, turkey, or roasted chicken. Consider adding festive cranberry sauce and warm cornbread on the side for a complete holiday spread that everyone will cherish.
