Southern Maple Sweet Potato Casserole is a warm and comforting dish that brings together tender, naturally sweet sweet potatoes and a rich maple syrup glaze. It’s topped with a crunchy layer of pecans or a golden, buttery crumb that adds just the right amount of texture and sweetness. It’s a perfect side dish that feels like a cozy hug on a plate.
I love making this casserole because it strikes the best balance between sweet and nutty flavors. The maple syrup gives it a gentle hint of caramel-like sweetness that makes it stand out from your usual sweet potato recipes. I usually prepare it ahead of time and let the flavors meld overnight, which makes it taste even better when warmed up the next day.
My favorite way to serve this is alongside a roast or grilled chicken for a simple family dinner, but it’s also a star on holiday tables. It’s one of those dishes that everyone asks for seconds of, and it makes me feel like I’m sharing a little southern comfort with everyone around the table.
Key Ingredients & Substitutions
Sweet Potatoes: Use firm, fresh sweet potatoes for the best flavor. If you can’t find them, yams are a good substitute but might be less sweet and moist.
Maple Syrup: Pure maple syrup adds natural sweetness and depth. If unavailable, honey or agave nectar work as alternatives, though the flavor will change slightly.
Nuts: Pecans and walnuts add a great crunchy topping. If you have a nut allergy, try toasted oats or pumpkin seeds instead for texture.
Butter & Milk: These add richness to the mash. Use plant-based butter and dairy-free milk to make it vegan-friendly.
How Can I Get the Perfect Topping Crunch?
Getting the nut topping just right adds a lovely contrast to the creamy sweet potatoes.
- Mix nuts with melted butter so they toast evenly and hold together.
- Spread the nut topping evenly over the sweet potatoes before baking.
- Bake uncovered to let the topping crisp up—about 30-35 minutes should do it.
- Keep an eye near the end to avoid burning and get a golden crust.
This simple step transforms the casserole from creamy and soft to a delightful blend of textures.

Equipment You’ll Need
- Large pot – to boil the sweet potatoes until tender.
- Mixing bowl – for mashing sweet potatoes and mixing ingredients smoothly.
- Hand masher or fork – makes it easy to mash sweet potatoes without lumps.

Flavor Variations & Add-Ins
- Add a pinch of ground ginger or allspice for a warmer, spiced flavor.
- Swap pecans for sliced almonds or chopped hazelnuts to change the nutty crunch.
- Mix in mini marshmallows on top for a classic sweet potato touch that’s extra creamy.
- Stir in cooked crisp bacon pieces for a salty contrast that balances the sweetness.

How Much Time Will You Need?
This recipe takes about 15-20 minutes to prep and boil the sweet potatoes, then about 30-35 minutes baking time. Overall, plan for roughly 50-60 minutes from start to finish, including cooling time before serving.
Step-by-Step Instructions:
1. Prepare the Oven and Sweet Potatoes:
Preheat your oven to 350°F (175°C) and lightly grease a 9×13-inch casserole dish. Peel and cube the sweet potatoes, then place them in a large pot. Cover with water and bring to a boil. Reduce the heat and simmer for 15-20 minutes until the potatoes are tender. Drain well.
2. Make the Sweet Potato Mixture:
Transfer the cooked sweet potatoes to a large bowl and mash them until smooth. In another bowl, whisk together the maple syrup, melted butter, brown sugar, milk or cream, eggs, vanilla extract, cinnamon, nutmeg, and salt. Pour this mixture into the mashed sweet potatoes and stir until everything is well combined and smooth.
3. Assemble and Bake:
Spoon the sweet potato mixture into the prepared casserole dish and smooth the top. In a small bowl, combine pecan halves, chopped walnuts, and the 2 tablespoons melted butter. Sprinkle this nut mixture evenly over the sweet potatoes. Bake uncovered for 30-35 minutes, until the topping is nicely toasted and the casserole is set.
4. Serve and Garnish:
Remove the casserole from the oven and let it cool slightly before serving. If you like, garnish with fresh rosemary sprigs for a lovely herbal aroma and extra color.

Can I Make This Casserole Ahead of Time?

What Can I Substitute for Pecans and Walnuts?
You can use other nuts like almonds or hazelnuts, or for a nut-free option, try toasted oats or pumpkin seeds for a crunchy topping.
