Step‑by‑Step Instructions for The Best Sweet Potato Casserole

Step 1: Roast Sweet Potatoes
Preheat your oven to 400°F (200°C). Place whole sweet potatoes on a baking sheet lined with parchment paper and roast them for 45-55 minutes, until tender when pierced with a fork. Once done, allow them to cool slightly, then peel away the skins. Mash the sweet potatoes until smooth; this creamy base will be the heart of your delicious Sweet Potato Casserole.

Step 2: Brown the Butter
In a medium saucepan over medium heat, melt ½ cup of salted butter. Allow it to cook for about 4-6 minutes, stirring frequently, until the butter turns golden brown and develops a nutty aroma. Be sure to keep a close eye on it to avoid burning. Once browned, promptly remove it from the heat and let it cool slightly before mixing it into your sweet potato mixture.

Step 3: Mix the Base
In a large mixing bowl, combine the mashed sweet potatoes with the browned butter. Add in ½ cup dark brown sugar, ¼ cup granulated sugar, ½ cup heavy whipping cream, a large egg, and an egg yolk. Incorporate 1 teaspoon of vanilla extract, 1 tablespoon of fresh lemon juice, ½ teaspoon of ground cinnamon, ¼ teaspoon of nutmeg, and a pinch of salt. Mix everything until fluffy and well-blended, creating a rich base for your Best Sweet Potato Casserole.

Step 4: Bake the Casserole
Spread the sweet potato mixture into a greased 7×10 or 8×8 baking dish. Preheat your oven to 350°F (175°C) and bake the casserole for 40-45 minutes. You’re looking for the edges to set while the center remains slightly firm; this step is crucial to achieving a smooth and creamy texture. The inviting aroma will fill your kitchen, highlighting that this Southern staple is on the way!

Step 5: Add Toppings
Once the casserole is baked, remove it from the oven and sprinkle with a light layer of dark brown sugar. Next, generously pile on mini marshmallows or marshmallow fluff. Return it to the oven for an additional 8-10 minutes, or alternatively, broil it for just 1-2 minutes until the marshmallows are golden and gooey. Keep a watchful eye during broiling to achieve the perfect toasted finish atop your sweet potato casserole.

Step 6: Serve
Allow your Best Sweet Potato Casserole to rest for about 10 minutes before serving. This waiting time lets the flavors meld beautifully while ensuring each serving holds its shape. Dish out warm portions alongside your favorite holiday meals, and relish the comforting, nostalgic delight that this casserole brings to your table!

Expert Tips for The Best Sweet Potato Casserole

Perfect Sweet Potatoes: Always roast your sweet potatoes instead of boiling. This enhances their natural sweetness and creates a creamy texture in your casserole.
Brown Butter Magic: Keep a close eye while browning butter. You want it to be golden with a nutty aroma, not burnt—this step brings extra richness to your dish.
Control the Sweetness: Adjust the granulated sugar according to your taste. If using store-bought sweet potatoes, be mindful as they may already have added sugars.
Master the Topping: If you prefer a toasted marshmallow finish, broil for only 1-2 minutes. It’s easy to overdo it—stay nearby to achieve that delightful golden-brown hue!
Make Ahead: Prepare the sweet potato base a day in advance and refrigerate. This saves time on the big day and allows flavors to develop before baking.

What should I do if my sweet potato casserole is too runny?
If your casserole turns out runny, it’s likely due to excess moisture in the sweet potatoes or too much cream. You can add a little cornstarch or extra mashed sweet potato to absorb some of the liquid. If you find it’s too late, try to bake it a bit longer to help the excess moisture evaporate.
