How to Make Southern Maple Sweet Potato Casserole
This casserole comes together in just a few simple steps:
- Roast the sweet potatoes until tender and caramelized (preferred over boiling to avoid excess moisture).
- Mix the filling with maple syrup, brown sugar, milk, butter, spices, raisins, and marshmallows.
- Transfer to a baking dish, adding extra marshmallows if desired.
- Top with maple-glazed pecans (or a traditional crumble topping).
- Bake until golden, gooey, and bubbling.
Let it cool slightly before serving for the perfect scoopable texture.
Key Ingredients You’ll Need
- Sweet Potatoes: Roasted for deeper flavor and better texture
- Pure Maple Syrup: Adds natural sweetness (avoid imitation syrup)
- Brown Sugar: Warm, caramel-like richness
- Milk: Almond milk or any dairy/plant-based option
- Butter: Unsalted for balanced flavor
- Raisins: Adds sweetness and texture (optional but recommended)
- Marshmallows: For classic gooey pockets of sweetness

How Many Sweet Potatoes Do You Need?
Four large sweet potatoes fit perfectly in a standard 9×13 baking dish and serve about 8 people. Feeding a crowd? Simply double or triple the ingredients—it scales beautifully.
When to Add Marshmallows (Important Tip!)
To avoid marshmallows melting away completely:
- Bake the casserole covered for the first half, then uncover
OR - Add half the marshmallows initially and tuck the rest in during the last 10 minutes
This keeps them soft, gooey, and visible in every bite.
