Step‑by‑Step Instructions for Sweet Potato Casserole with Butter Pecan Crumble
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). While it warms up, grease a 9×13-inch baking dish with butter or cooking spray to prevent sticking. This will ensure your Sweet Potato Casserole with Butter Pecan Crumble comes out perfectly cooked and easy to serve.
Step 2: Boil Sweet Potatoes
Peel sweet potatoes and cut them into chunks. Place the pieces into a large pot of boiling water and cook for 15-20 minutes, or until fork-tender. Drain the sweet potatoes thoroughly to avoid excess water in your casserole base. This step is crucial for achieving the right texture in your sweet potato mixture.
Step 3: Mash Sweet Potatoes
In a large mixing bowl, mash the drained sweet potatoes until smooth. Then, while still warm, combine them with melted butter, light brown sugar, heavy cream (or milk), beaten eggs, vanilla extract, cinnamon, nutmeg, and a pinch of salt. Mix well until the mixture is creamy and fully combined, creating a delicious base for your casserole.
Step 4: Spread the Sweet Potato Mix
Carefully spread the sweet potato mixture evenly into the prepared baking dish. Use a spatula to smooth the top, ensuring an even layer. This creates the perfect foundation for the crunchy topping that will transform your Sweet Potato Casserole with Butter Pecan Crumble into a standout dish for your holiday table.
Step 5: Prepare the Pecan Crumble
In a separate bowl, combine the remaining light brown sugar, melted butter, all-purpose flour, cinnamon, and chopped pecans. Use your fingers or a fork to mix them until crumbly. This mixture will add that delightful crunch and nutty flavor to the top of your casserole. Make sure it resembles coarse crumbs for best results.
Step 6: Add the Pecan Topping
Sprinkle the pecan crumble evenly over the sweet potato layer in the baking dish. Spread it gently, ensuring each delicious bite of the Sweet Potato Casserole with Butter Pecan Crumble will have that irresistible crunch. It’s that perfect topping that turns an already fantastic dish into a crowd-pleaser.
Step 7: Bake to Perfection
Place the baking dish in the preheated oven and bake for 30-35 minutes. You’ll know it’s done when the topping is golden brown and crisp, with a warm aroma wafting through your kitchen. This final step melds all the flavors together beautifully, creating a charming holiday side dish.
Step 8: Cool and Serve
After baking, allow the casserole to cool for a few minutes before serving. This short wait enhances the flavors and makes it easier to cut into portions. Serve warm as a delightful addition to your holiday feast, showcasing your Sweet Potato Casserole with Butter Pecan Crumble with pride.
