How to Make Sweet Potato Casserole from Scratch

1. Preheat your oven to 350°F (175°C) and lightly grease a 9×13 inch baking dish.
2. Place sweet potato chunks in a large pot and cover with water. Bring to a boil over high heat, then reduce to medium heat and cook until the potatoes are fork-tender, about 15-20 minutes.
3. Drain the sweet potatoes thoroughly and return them to the pot.
4. Add the softened butter, brown sugar, cinnamon, nutmeg, vanilla extract, milk, and salt to the pot with the sweet potatoes.
5. Mash the mixture until smooth and creamy. For an extra smooth texture, you can use an electric mixer.
6. Spread the sweet potato mixture evenly into your prepared baking dish.
7. Bake in the preheated oven for 25 minutes until the sweet potato mixture is heated through and set.
8. Remove from the oven and evenly sprinkle the mini marshmallows over the top.
9. Return to the oven and bake for an additional 5-10 minutes, or until the marshmallows are puffy and golden brown. Watch carefully to prevent burning!
10. Allow to cool slightly before serving warm.

Pro Tips for Perfect Sweet Potato Casserole

• Consistent chunks: Cut your sweet potatoes into similarly-sized pieces so they cook evenly.
• Roasting option: For deeper flavor, roast your sweet potatoes instead of boiling them. Pierce with a fork and bake at 400°F for 45-60 minutes until soft.
• Marshmallow watch: Keep a close eye on your marshmallows during the final minutes of baking – they can go from perfectly golden to burnt very quickly!
• Make ahead: You can prepare the sweet potato mixture up to 2 days ahead. Store in the refrigerator, then bring to room temperature, top with marshmallows, and bake just before serving.

Sweet Potato Casserole Variations to Try

Pecan Crumble Topping

For a crunchy alternative to marshmallows, mix 1/2 cup brown sugar, 1/3 cup flour, 1/3 cup melted butter, and 1 cup chopped pecans. Sprinkle over the sweet potato mixture before baking.

Maple Sweet Potato Casserole

Replace the brown sugar with 1/3 cup pure maple syrup for a more complex sweetness that complements the sweet potatoes beautifully.

Streusel-Topped Version

Create a streusel topping with 1/2 cup flour, 1/2 cup brown sugar, 4 tablespoons cold butter cut into pieces, and 1/4 teaspoon cinnamon. Cut together until crumbly and sprinkle over the casserole before baking.

Common Questions About Sweet Potato Casserole

Can I make sweet potato casserole ahead of time?

Yes! You can prepare the sweet potato mixture 1-2 days ahead and refrigerate. When ready to serve, bring to room temperature, add the marshmallow topping, and bake until hot and the marshmallows are golden.

What’s the difference between sweet potato casserole and candied yams?

Sweet potato casserole typically features mashed sweet potatoes with a topping, while candied yams often involve sliced sweet potatoes in a syrupy sauce. Despite the name, both dishes usually use sweet potatoes, not true yams.

Can I freeze sweet potato casserole?

You can freeze the prepared sweet potato mixture (without marshmallows) for up to 3 months. Thaw overnight in the refrigerator, then top with marshmallows and bake as directed.

How do I know when my sweet potatoes are done boiling?

Sweet potatoes are done when you can easily pierce them with a fork or knife with little resistance, usually after 15-20 minutes of boiling.
