Step‑by‑Step Instructions for Ultimate Sweet Potato Casserole Bake: Easy, Cozy & Irresistible
Step 1: Preheat and Prepare the Dish
Begin by preheating your oven to 350°F (175°C). While the oven warms, grab a 9×13-inch baking dish and lightly grease it with butter or non-stick spray. This step ensures that your Ultimate Sweet Potato Casserole Bake comes out easily after baking, allowing the crispy topping to shine.
Step 2: Boil the Sweet Potatoes
Peel and cube the sweet potatoes into 1-inch chunks for even cooking. In a large pot, add the sweet potatoes and enough salted water to cover them. Bring the water to a boil and let the potatoes cook for 15-20 minutes, or until they are fork-tender. Drain the cooked sweet potatoes and return them to the pot to keep them warm.
Step 3: Mash the Sweet Potatoes
To the warm sweet potatoes, add the unsalted butter, brown sugar, whole milk, vanilla extract, ground cinnamon, ground nutmeg, and salt. Using a potato masher or fork, mash the mixture until it reaches a creamy consistency. This deliciously spiced filling will form the base of your Ultimate Sweet Potato Casserole Bake.
Step 4: Spread the Sweet Potato Mixture
Transfer the creamy mashed sweet potato mixture into the prepared baking dish. Use a spatula to spread it evenly, ensuring a smooth top layer that will help hold the delicious topping. This layer acts as a comforting foundation, ready to be enhanced with the crispy topping.
Step 5: Prepare the Topping
In a separate bowl, combine the chopped pecans or walnuts, brown sugar, all-purpose flour, and melted butter. Mix these ingredients together until crumbly, creating a delightful topping for your casserole. This crunchy layer adds texture to the Ultimate Sweet Potato Casserole Bake that contrasts perfectly with the creamy filling.
Step 6: Assemble and Bake
Sprinkle the topping mixture evenly over the sweet potato layer in the baking dish. Gently press it down with your hands to ensure it adheres well. Place the casserole in the preheated oven and bake for 25-30 minutes, or until the topping turns golden brown and deliciously crispy, with the filling bubbling slightly around the edges.
Step 7: Rest Before Serving
After baking, remove the casserole from the oven and let it rest for about 10 minutes. This brief cooling time allows the flavors to meld and the casserole to set, making it easier to serve and enjoy. The Ultimate Sweet Potato Casserole Bake is now ready to bring warmth and joy to your table!

How to Store and Freeze Ultimate Sweet Potato Casserole Bake
Fridge: Store leftovers in an airtight container for up to 4 days to maintain freshness and flavor.
