Difficulty Level

Ingredients
- 4 cups mashed sweet potatoes (about 4 large sweet potatoes, peeled and boiled)
- 1/2 cup granulated sugar
- 1/3 cup unsalted butter, melted
- 1/2 cup whole milk
- 2 large eggs, lightly beaten
- 1 teaspoon vanilla extract
- 1/2 teaspoon ground cinnamon
- 1/4 teaspoon ground nutmeg
- 1/4 teaspoon salt
- 1 cup mini marshmallows (optional for topping)
Instructions
- Prepare the sweet potatoes: Peel and cube the sweet potatoes, then boil in salted water for 15-20 minutes or until tender when pierced with a fork. Drain well.
- Mash the potatoes: Using a potato masher or electric mixer, mash the sweet potatoes until smooth but still slightly textured for the best mouthfeel.
- Combine wet ingredients: In a large mixing bowl, whisk together the melted butter, milk, eggs, and vanilla extract until well incorporated.
- Mix the casserole base: Fold the mashed sweet potatoes into the wet mixture along with sugar, cinnamon, nutmeg, and salt. Stir gently to combine evenly without overworking the potatoes.
- Transfer to baking dish: Pour the mixture into a buttered 9×13-inch casserole dish, smoothing the top with a spatula.
- Add your topping: For the classic version, sprinkle evenly with mini marshmallows or your preferred crunchy topping variation (see below).
- Bake: Place the casserole in a preheated 350°F (175°C) oven for 30-35 minutes, until the edges are bubbling and the topping is golden and slightly crispy.
- Rest before serving: Allow the casserole to cool for 5-10 minutes-it will firm up slightly, making it easier to serve while keeping that luscious moisture inside.
Chef’s Notes: Secrets to Perfect Sweet Potato Casserole Texture and Flavor
- For silkier sweetness: Incorporate a splash of heavy cream rather of milk for richer texture.
- Enhance natural sweetness: Roast your sweet potatoes instead of boiling to develop caramelized flavor notes.
- Avoid watery casseroles: Drain thoroughly and dry potatoes well after boiling or roasting to prevent excess moisture.
- Balancing spices: Cinnamon and nutmeg are classic, but adding a pinch of ginger or allspice offers an unexpected warmth.
- Make ahead friendly: Prepare the base a day ahead and keep refrigerated. Add topping just before baking for fresh texture.
Topping Variations That Elevate Your Sweet Potato Casserole
- Pecan praline crunch: Toss 1 cup chopped pecans with 1/3 cup brown sugar and 3 tablespoons melted butter; sprinkle over casserole before baking for a caramelized, nutty crust.
- brown sugar streusel: Mix 1/2 cup brown sugar, 1/2 cup all-purpose flour, 1/4 cup softened butter, and 1/4 teaspoon cinnamon until crumbly; add a crisp, buttery topping.
- Classic marshmallow bliss: Use mini marshmallows for a gooey golden top, broiling in the last 2 minutes to toast lightly.
- Coconut and pecan topping: Combine shredded coconut, chopped pecans, melted butter, and a pinch of salt for a tropical flair.
Expert Tips for Baking and Serving a Crowd-Pleasing Sweet Potato Casserole
- Even layering is key: Smooth the casserole surface evenly before applying toppings to encourage uniform baking.
- Watch your timing: Baked too long, the casserole dries out; too short, it may be undercooked. Keep a close eye during the final 10 minutes.
- Serve warm, not hot: Let resting take effect to enhance flavors and ease portioning.
- presentation tips: Garnish with fresh chopped parsley or a sprinkle of cinnamon for a pop of color and enhanced aroma.
- Serving for a crowd: Use a large ceramic or cast-iron dish to retain heat longer during serving at gatherings.
