For the Casserole

• Melted butter – enhances flavor; feel free to substitute with coconut oil for a dairy-free version.
• Brown sugar – sweetens the dish naturally, creating that comforting taste we love.
• Vanilla extract – a splash of this adds depth to the flavors.
• Cinnamon – warms up the flavor profile and pairs perfectly with sweet potatoes.
• Nutmeg – a pinch adds a lovely aromatic note that elevates the dish.
• Salt – balances the sweetness for that perfect flavor harmony.
For the Topping
• Chopped pecans – these give the casserole a delightful crunch; walnuts can be a great substitute too.

Step‑by‑Step Instructions for Sweet Potato Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This will ensure it reaches the perfect temperature while you prepare the sweet potato filling. A warm oven is essential to achieve that delightful, golden topping on your Sweet Potato Casserole.
Step 2: Boil the Sweet Potatoes
In a large pot, add the cubed sweet potatoes and cover them with water. Bring the water to a boil over medium-high heat and let the sweet potatoes cook for about 10 to 15 minutes, or until they are fork-tender. This softening process is key for a smooth casserole.
Step 3: Mash the Potatoes
Once they're tender, drain the sweet potatoes and return them to the pot. Using a potato masher or a fork, mash the sweet potatoes until smooth and fluffy. You'll want a creamy texture, which serves as the comforting base for your Sweet Potato Casserole.
Step 4: Mix in the Ingredients
While the potatoes are still warm, add in the milk, melted butter, brown sugar, vanilla extract, cinnamon, nutmeg, and salt. Stir well until everything is thoroughly combined. The warmth of the sweet potatoes helps to meld these flavors beautifully, creating a tasty filling.
Step 5: Prepare the Baking Dish
Grab a 9×13-inch baking dish and grease it lightly with butter or cooking spray. This will prevent your Sweet Potato Casserole from sticking. Transfer the creamy sweet potato mixture into the prepared baking dish, spreading it out evenly to ensure even cooking.
Step 6: Make the Topping
In a small bowl, mix together the chopped pecans, brown sugar, and melted butter. This topping will give your casserole its delicious, crunchy texture. Once combined, sprinkle this mixture generously over the sweet potato layer, covering it evenly for perfect caramelization.
Step 7: Add Marshmallows (Optional)
For an extra touch, feel free to layer mini marshmallows on top of the pecan mixture if desired. These will melt and caramelize, adding a sweet and nostalgic flair to your Sweet Potato Casserole, appealing to both kids and adults alike.
Step 8: Bake to Perfection
Place the baking dish in the preheated oven and bake for 25 to 30 minutes, or until the topping is golden, crispy, and bubbly. Keep an eye on it towards the end to ensure it doesn’t over-bake. The aroma that fills your kitchen will be irresistible and will get everyone excited for dinner!
