How to Make Southern Sweet Potato Casserole
-
Preheat the oven to 350°F. This ensures your casserole will bake evenly, creating that golden, bubbly finish we all love.
-
Wrap the sweet potatoes in foil and place them on a baking sheet. Bake for about 1 hour, or until fork-tender. If you’re using canned sweet potatoes, simply drain the syrup and skip this step.
-
Peel the sweet potatoes once cool enough to handle. Discard any tough or stringy pieces. Place the buttery potatoes in a large bowl and mash until mostly smooth.
-
Mix in the eggs, salt, cinnamon, vanilla, and nutmeg. Keep mashing until you achieve a uniform, creamy texture. Add the brown sugar and heavy cream, and stir thoroughly.
-
Combine the flour, brown sugar, salt, oats, and cinnamon in a medium bowl. Stir well, then add the butter chunks. Use a fork to mix until you have a crumbly, streusel-like consistency.
-
Grease a 9 x 13-inch baking pan with butter or non-stick spray. Spread the sweet potato mixture evenly in the pan. Top with marshmallows first, then sprinkle the oatmeal crumb topping over the marshmallows.
-
Bake for 30 to 40 minutes at 350°F, or until everything is heated through and the topping is golden brown and crispy.
Optional: Sprinkle with extra cinnamon before serving for an added touch of flavor.

Make Ahead Options
These Southern Sweet Potato Casserole makes meal prep a breeze for busy cooks! You can prepare the sweet potato filling up to 24 hours in advance by cooking and mashing the sweet potatoes, mixing in the butter, eggs, and spices, then storing it in an airtight container in the refrigerator.

When ready to serve, simply spread the sweet potato mixture in the greased baking dish, add the marshmallows, sprinkle the topping on top, and bake at 350°F for 30 to 40 minutes. This make-ahead strategy guarantees you’ll have a comforting, delicious dish with minimal effort on busy nights!
