Step‑by‑Step Instructions for Sweet Potato Casserole with Pecan Streusel
Step 1: Prepare Sweet Potatoes
Begin by peeling, chunking, and rinsing about 2 pounds of fresh sweet potatoes. Fill a large pot with water, add the sweet potatoes, and bring to a boil. Cook for 15–20 minutes until fork-tender; you should be able to easily pierce them with a fork. Drain the sweet potatoes well in a colander, ensuring excess moisture is removed.
Step 2: Mash
Transfer the drained sweet potatoes to a mixing bowl. Using a potato masher or electric mixer, mash the sweet potatoes until they’re smooth and creamy without any lumps. This step is essential for achieving a velvety texture in your Sweet Potato Casserole with Pecan Streusel, making it a delightful base for the creamy filling.
Step 3: Mix Sweet Potato Base
To the mashed sweet potatoes, add ½ cup of unsalted butter, ½ cup of milk, 2 eggs, and 1 teaspoon each of vanilla extract, cinnamon, and nutmeg. Incorporate ½ teaspoon of salt to elevate the flavors. Mix everything together until fully blended, creating a rich and creamy batter that will be the heart of your casserole.
Step 4: Make Streusel Topping
In a separate bowl, combine 1 cup of flour, ¾ cup of brown sugar, ½ teaspoon of cinnamon, and a pinch of salt. Cut in ½ cup of cold butter using a pastry cutter or your fingers until the mixture resembles coarse crumbs. Fold in 1 cup of chopped pecans to bring that irresistible crunch to your Sweet Potato Casserole with Pecan Streusel.
Step 5: Assemble Casserole
Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with cooking spray or butter. Pour the creamy sweet potato mixture into the dish, spreading it evenly with a spatula. Then, sprinkle the prepared pecan streusel topping generously over the sweet potato base, ensuring every inch is covered for an even bake.
Step 6: Bake
Place the assembled casserole in the preheated oven and bake for 30–40 minutes. Look for the topping to turn a delicious golden brown and the edges to bubble slightly; this indicates that the Sweet Potato Casserole with Pecan Streusel is perfectly cooked and ready to serve.
Step 7: Cool and Serve
Once baked, remove the casserole from the oven and let it cool for about 10 minutes before serving. This brief cooling period allows the casserole to set slightly, making it easier to scoop out portions. Prepare to enjoy the delightful combination of creamy sweet potatoes and a crunchy pecan topping!
