Ingredients You’ll Need
Every ingredient in this Southern Maple Sweet Potato Casserole Recipe plays a crucial role in building layers of flavor and texture. From the naturally sweet and creamy sweet potatoes to the crunchy pecan topping, each item is thoughtfully selected to create a harmonious dish that’s both rich and inviting.
- Sweet potatoes: The heart of the casserole, providing natural sweetness and creamy texture when mashed.
- Maple syrup: Adds deep, rich sweetness with a subtle caramel note that complements the potatoes beautifully.
- Butter (or vegan butter for dairy-free): Brings richness and a silky mouthfeel to the mash and streusel topping.
- Whole milk (or plant-based milk for dairy-free): Lightens the sweet potato mash, making it perfectly creamy.
- Ground cinnamon: Infuses warm spice that enhances the natural sweetness of the potatoes.
- Ground nutmeg: Adds a hint of earthy depth to the spice blend, balancing the sweetness.
- Vanilla extract: Provides a fragrant, sweet aroma that rounds out the flavors beautifully.
- Salt: The essential ingredient that brings out all the individual flavors.
- Brown sugar: Sweetens and caramelizes in the topping for a delightful crunch.
- Pecans (or walnuts for substitution): Adds buttery nuttiness and a satisfying crunch to the streusel topping.
- All-purpose flour (or gluten-free flour for gluten-free option): Binds the topping ingredients together, ensuring a perfect crumble.

How to Make Southern Maple Sweet Potato Casserole Recipe
Step 1: Prepare the Oven and Potatoes
Start by preheating your oven to 350°F (175°C) and greasing a 9×13-inch baking dish so your casserole won’t stick and can bake evenly. Meanwhile, peel and cube the sweet potatoes, then boil them in a large pot for 12-15 minutes until they become tender enough to mash with ease. This step ensures your sweet potatoes will be perfectly soft and ready to absorb all the delicious flavors you’ll mix in next.
Step 2: Mash and Flavor the Sweet Potatoes
Drain your cooked sweet potatoes and return them to the pot. Mash them until they’re smooth and lump-free. Then stir in the maple syrup, melted butter, milk, ground cinnamon, nutmeg, vanilla extract, and a pinch of salt. This combination creates a creamy, spiced base quality typical of this Southern Maple Sweet Potato Casserole Recipe. Don’t rush here — get the flavors blended until everything feels luscious and just right.
Step 3: Spread the Sweet Potato Mixture
Transfer your creamy sweet potato mash into the prepared baking dish, gently smoothing the surface. This even layer is the foundation of your casserole and sets the stage for the crunchy topping. Making it smooth will ensure the streusel topping stays put and bakes beautifully.
Step 4: Prepare the Streusel Topping
In a small bowl, mix brown sugar, chopped pecans, all-purpose flour, rolled oats, and softened butter until you achieve a crumbly texture. This streusel topping delivers a fantastic contrast to the smooth sweet potatoes, adding a sweet, nutty crunch that is absolutely irresistible.
Step 5: Assemble and Bake
Sprinkle the streusel mixture evenly over the sweet potato base, making sure every bit is covered so it bakes into golden, crunchy perfection. Pop the casserole into the oven and bake for 25-30 minutes, until the topping turns a gorgeous golden color and the casserole bubbles around the edges. Once out of the oven, allow it to cool slightly — this helps everything settle and makes serving a breeze.

Make Ahead and Storage
Storing Leftovers
Once cooled, cover any leftover Southern Maple Sweet Potato Casserole Recipe tightly with plastic wrap or foil and refrigerate. It stays fresh for about 3-4 days, making it perfect for enjoying throughout the week after your big meal.
Freezing
You can freeze the casserole either before or after baking. Wrap it well with plastic wrap and aluminum foil to prevent freezer burn. It stays good for up to 2 months. When ready, thaw overnight in the fridge before reheating to preserve the best texture and flavor.
Reheating
Reheat leftovers by placing the casserole in a preheated 350°F (175°C) oven for 15-20 minutes, or until warmed through and the topping regains its crispiness. Avoid microwaving if you can, as the topping may lose its crunch.
FAQs
Can I make this Southern Maple Sweet Potato Casserole Recipe vegan?
Absolutely! Substitute the butter with vegan butter and use your favorite plant-based milk instead of whole milk. The flavor and texture will be just as delicious.
What nuts can I use instead of pecans?
Walnuts are a fantastic substitute and provide a similar texture and flavor. If you’re nut-free, you can omit nuts and add extra oats for crunch.
Is it possible to make this gluten-free?
Yes, just replace the all-purpose flour with gluten-free flour and use gluten-free rolled oats to keep the topping safe for gluten-sensitive diets.
Can I prepare this casserole ahead of time?
Definitely! You can assemble it the day before, cover it, and refrigerate. Bake it fresh the next day when you’re ready to serve.
How sweet is the casserole? Can I adjust the sugar?
It’s moderately sweet with natural sweetness from the maple syrup and brown sugar. If you prefer it less sweet, simply reduce the sweeteners slightly without sacrificing flavor.
