Step‑by‑Step Instructions for Southern Maple Sweet Potato Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C). This temperature ensures a perfect bake for your Southern Maple Sweet Potato Casserole, allowing the sweet potatoes to caramelize beautifully. Set your oven rack to the center position, where heat distribution is ideal, and let it warm up while you prepare your ingredients.
Step 2: Roast the Sweet Potatoes
In a large bowl, combine cubed sweet potatoes with a drizzle of olive oil, ground cinnamon, and nutmeg. Spread the seasoned sweet potatoes onto a baking sheet lined with parchment paper. Roast in the preheated oven for 50–60 minutes, or until they are tender and slightly caramelized, turning them halfway for even roasting.
Step 3: Prepare the Filling
Once roasted, remove the sweet potatoes from the oven and let them cool for roughly 10 minutes. In a mixing bowl, mash the warm sweet potatoes with almond milk, vanilla extract, brown sugar, maple syrup, cinnamon, nutmeg, allspice, raisins, and marshmallows until combined but still slightly chunky. This creates a delightful filling for your casserole.
Step 4: Assemble the Casserole
Grease a 9×13-inch baking dish with a little butter or cooking spray, ensuring a non-stick surface for your casserole. Transfer the sweet potato mixture to the prepared baking dish, spreading it evenly. Tuck in small cubes of unsalted butter and any extra marshmallows over the top for added sweetness and richness.
Step 5: Make the Topping
In a separate bowl, combine raw pecans with maple syrup, mixing until the pecans are well-coated. Sprinkle this maple-pecan mixture generously on top of the sweet potato filling, ensuring every bite will be flavorful and crunchy. This topping will add a wonderful texture contrast to your Southern Maple Sweet Potato Casserole.
Step 6: Bake the Casserole
Cover the assembled casserole with aluminum foil to prevent the top from burning. Place it in the oven and bake for 15 minutes. Afterward, carefully remove the foil and continue to bake for another 15 minutes, or until the top is golden brown and the marshmallows are soft and slightly caramelized, creating a delicious crust.
Step 7: Cool & Serve
Once finished baking, remove the casserole from the oven and allow it to cool for about 5–10 minutes. This cooling period helps the flavors meld and makes serving easier. Spoon portions onto plates and prepare for lots of compliments on your irresistibly creamy and flavorful Southern Maple Sweet Potato Casserole!

Expert Tips for Southern Maple Sweet Potato Casserole
-
Perfectly Roasted Sweet Potatoes: Ensure even cooking by cutting the sweet potatoes into uniform cubes. This will help them caramelize beautifully and create that rich flavor.
-
Avoid Overmixing: When preparing the filling, mix until just combined. Leaving it slightly chunky enhances the casserole’s texture and prevents it from becoming too mushy.
-
Customize Sweetness: Taste as you go and adjust the sweetness by adding more maple syrup or brown sugar based on personal preference, ensuring your Southern Maple Sweet Potato Casserole is just right for you.
-
Marshmallow Magic: For that delightful toasted top, remember to bake covered initially and then uncover for the last 15 minutes. This prevents burning while achieving that perfect golden color.
-
Make-Ahead Convenience: Roast the sweet potatoes a day in advance and store them in the refrigerator. This makes assembly a breeze on the day you plan to serve your casserole.
