Southern Maple Sweet Potato Casserole is a cozy, comforting dish that brings together the natural sweetness of roasted sweet potatoes with a touch of maple syrup and a crunchy, buttery topping. Think tender, velvety sweet potatoes baked to perfection, layered with a golden crust of pecans or brown sugar that adds just the right amount of crispness. This casserole feels like a warm hug from the South on a chilly day.
I love making this casserole during the holidays or any family gathering because it always gets rave reviews. The combination of maple syrup’s gentle sweetness with the earthiness of sweet potatoes is something everyone seems to adore. I like to prepare it a day ahead so the flavors really have time to meld together – it tastes even better the next day!
When serving, I like to set this casserole on the table alongside ham or roast chicken. It works beautifully as a side that complements both savory meals and festive spreads. Plus, there’s always a little extra for snacking later, and I won’t lie, I’m usually the first to sneak a spoonful right out of the baking dish. It’s the perfect mix of soft, sweet, and crunchy – a real Southern classic that brings comfort and smiles every time.
Key Ingredients & Substitutions
Sweet potatoes: Use large, firm sweet potatoes with smooth skin for the best texture and natural sweetness. If you can’t find them, yams or even pumpkin puree can work as alternatives, but the flavor will be a bit different.
Maple syrup: Pure maple syrup adds a unique, warm sweetness. If needed, you can substitute with honey or agave syrup, but I find maple gives the most authentic Southern taste.
Pecans: Pecans are crucial for that classic crunchy topping. If you’re out of pecans, walnuts or almonds work too, but pecans have a buttery flavor that pairs perfectly here.
Butter: Unsalted butter is best so you can control the saltiness. For dairy-free diets, use vegan butter or coconut oil, which still add richness.
How Do You Make the Perfect Pecan Topping Crunchy Without Burning?
The pecan topping brings texture but can burn if baked too long or too hot. Here’s how I keep it just right:
- Use cold, cubed butter and mix it quickly with brown sugar, flour, and pecans. This creates a crumbly mix that crisps well without melting too fast.
- Sprinkle the topping evenly over the sweet potato mash for consistent baking.
- Bake uncovered at 350°F (175°C) for 30-35 minutes, watching the color closely near the end so it doesn’t get too dark.
- If the nuts are browning too fast, loosely cover the casserole with foil for the last 10 minutes.
Following these steps helps you get that golden, crunchy topping that contrasts beautifully with the soft casserole underneath.
Equipment You’ll Need
- Large pot – perfect for boiling sweet potatoes until tender.
- Mixing bowl – to mash and mix all the sweet potato ingredients smoothly.
- Masher or electric mixer – makes sweet potatoes creamy and lump-free.
- 9×13-inch baking dish – roomy enough to bake the casserole evenly.
- Pastry cutter or fork – helps mix the cold butter into the pecan topping easily.
- Measuring cups and spoons – for precise ingredient amounts.
Flavor Variations & Add-Ins
- Swap pecans with walnuts for a milder, earthier crunch.
- Add a pinch of ground ginger or cloves for a warm, spicy twist.
- Mix in mini marshmallows on top during the last 5 minutes of baking for a sweet, gooey finish.
- Stir in cooked bacon bits to the sweet potatoes for a salty, smoky contrast.

How Much Time Will You Need?
The total cooking time is about 1 hour. You’ll spend around 20 minutes preparing and boiling the sweet potatoes, about 10 minutes mixing the casserole and topping, then bake it for 30 to 35 minutes until golden and bubbly. Allow a few extra minutes to rest before serving.
Step-by-Step Instructions:
1. Prepare the Sweet Potatoes:
Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking dish. Peel the sweet potatoes and cut them into chunks. Boil in a large pot of water for 15 to 20 minutes, or until tender. Drain and mash thoroughly in a large bowl.
2. Mix the Sweet Potato Filling:
Add maple syrup, melted butter, milk or cream, eggs, vanilla extract, cinnamon, nutmeg, and salt to the mashed sweet potatoes. Stir well until everything is smooth and combined.
3. Prepare the Pecan Topping:
In a separate bowl, combine pecans, brown sugar, flour, and salt if using. Add the cold cubed butter, then work it in with your fingers or a pastry cutter until the mixture becomes crumbly and the butter is well distributed.
4. Assemble and Bake:
Spread the sweet potato mixture evenly into the prepared baking dish. Sprinkle the pecan topping over the top. Bake uncovered for 30 to 35 minutes, until the topping is golden brown and the casserole is set.
5. Serve and Enjoy:
Let the casserole rest for 5 minutes out of the oven. If you like, drizzle a little extra maple syrup on top for added sweetness before serving. Enjoy this warm, comforting dish as the perfect side to your favorite Southern meal!
Can I Use Frozen Sweet Potatoes for This Casserole?
Yes, you can use frozen sweet potato cubes or puree. Just make sure to thaw them completely and drain any excess moisture before mixing with the other ingredients to prevent a watery casserole.
How Long Can I Store Leftovers?
Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in the oven or microwave until warmed through, adding a splash of milk if it seems dry.
Can I Make This Casserole Ahead of Time?
Absolutely! You can prepare the casserole and topping a day in advance. Cover and refrigerate it, then bake it fresh when ready to serve. You may need to add a few extra minutes to the baking time if baking straight from the fridge.
What’s a Good Substitute for Pecans?
Walnuts or sliced almonds make great substitutes if you’re out of pecans. They provide a similar crunch and nutty flavor, though pecans are the traditional choice for that classic Southern taste.
