Southern Maple Sweet Potato Casserole is a warm, comforting dish that brings together the natural sweetness of roasted sweet potatoes and the rich flavor of pure maple syrup. Topped with a crunchy layer of toasted pecans, this casserole balances soft, creamy filling with a delightful nutty crunch, making it a perfect addition to any family meal or holiday feast.
I love making this casserole when I want a dish that’s both simple and special. The maple syrup adds just the right touch of sweetness without being overpowering, and the pecans give it that extra hint of Southern charm. One tip I always follow is to mash the sweet potatoes just enough to keep the texture a little chunky—it makes every bite more interesting and homemade.
We often serve this casserole alongside savory dishes, but honestly, it’s so tasty on its own that I sometimes treat it like dessert! It’s one of those recipes that brings everyone to the table with smiles, and I know I’ll be making it every year because it’s always such a hit. If you’re looking for a cozy, flavorful dish that feels like a warm hug, this sweet potato casserole fits the bill perfectly.
Key Ingredients & Substitutions
Sweet potatoes: The star of this dish! I like using large, firm sweet potatoes because they mash well and have a nice natural sweetness. If you can’t find them, Japanese sweet potatoes work great too.
Maple syrup: Pure maple syrup adds a rich, natural sweetness that pairs wonderfully with the spices. If you don’t have maple syrup, honey or agave syrup can be a nice substitute.
Butter: Butter adds creaminess and richness to both the sweet potato mixture and topping. You can swap with a vegan butter if you want a dairy-free option.
Milk: Whole milk makes the mash smooth and creamy. For a lighter or dairy-free alternative, try almond milk or oat milk.
Pecans: These give the casserole a crunchy, toasted finish. If you prefer, walnuts can be a good substitute, or leave nuts out for a nut-free version.
How Do I Get the Perfect Crunchy Topping?
The topping is what makes this casserole extra special. To get that perfect crunch, mix the pecans, brown sugar, flour, cinnamon, and cold butter until it looks like coarse crumbs. Using cold butter helps create little pockets of richness that bake into crisp pieces.
- Make sure to distribute the topping evenly over the sweet potatoes.
- Bake uncovered so the topping crisps up nicely.
- Keep an eye during the last few minutes so it gets golden but doesn’t burn.
This step adds a wonderful contrast to the creamy potatoes underneath, and it’s worth the little extra effort!
Equipment You’ll Need
- Large pot – perfect for boiling sweet potatoes until tender.
- Potato masher – helps mash sweet potatoes to a creamy, slightly chunky texture.
- Mixing bowls – you’ll need at least two: one for sweet potatoes, one for the topping.
- 9×13-inch baking dish – roomy enough for the casserole to bake evenly without spilling.
- Pastry cutter or fork – great for mixing cold butter into the topping to get that crumbly texture.
- Rubber spatula – makes it easy to spread the sweet potato mixture smoothly in the dish.
Flavor Variations & Add-Ins
- Add a pinch of ground ginger or allspice for a little extra warmth and spice.
- Mix in 1/2 cup mini marshmallows on top during the last 5 minutes of baking for a sweet, gooey touch.
- Stir in cooked, crumbled bacon or pancetta to add smoky, salty flavor that contrasts nicely.
- Swap pecans for chopped walnuts or almonds if you want a different nutty crunch.

How Much Time Will You Need?
This recipe takes about 15 minutes to prepare, 20 minutes to cook the sweet potatoes, and 25-30 minutes to bake the casserole. In total, expect around 1 hour from start to finish.
Step-by-Step Instructions:
1. Prepare the Sweet Potatoes:
Start by preheating your oven to 375°F (190°C) and greasing a 9×13 inch baking dish. Peel the sweet potatoes and cut them into chunks. Place them in a large pot and cover with water. Bring to a boil, then lower the heat and simmer for about 20 minutes, or until very tender.
2. Mash and Mix:
Drain the sweet potatoes and put them in a large bowl. Mash them until mostly smooth but still a bit chunky for a nice texture. Stir in the maple syrup, melted butter, milk, vanilla extract, cinnamon, nutmeg, salt, and pepper. Mix well until creamy and combined.
3. Make the Topping and Bake:
In a separate bowl, combine chopped pecans, brown sugar, flour, and cinnamon. Add the cold butter pieces, then use your fingers or a pastry cutter to mix until the topping looks like coarse crumbs. Spread the sweet potato mixture evenly in your baking dish, then sprinkle the topping over it.
Bake uncovered for 25-30 minutes until the topping turns golden brown and crisp. Let the casserole cool for a few minutes before serving. Enjoy this delicious, sweet, and nutty dish!
Can I Use Frozen Sweet Potatoes for This Casserole?
Yes, you can use frozen sweet potatoes—just be sure to fully thaw and drain them before mashing to avoid extra moisture. This helps maintain the right texture in the casserole.
How Do I Store Leftovers?
Store leftover casserole in an airtight container in the fridge for up to 3 days. Reheat gently in the oven or microwave until warm, adding a splash of milk if needed to keep it creamy.
Can I Make This Ahead of Time?
Absolutely! Prepare the sweet potato mixture and topping, assemble the casserole, then cover and refrigerate for up to 24 hours. Bake as directed when ready to serve, adding a few extra minutes of baking time if cold.
What Can I Substitute for Pecans?
If you’re allergic or prefer a different nut, walnuts or almonds work well in the topping. For a nut-free option, skip the nuts and increase the brown sugar and flour slightly for a crumbly, sweet topping.
