Step‑by‑Step Instructions for Sweet Potato Casserole Recipe
Step 1: Preheat and Prepare
Preheat your oven to 350°F (175°C) and lightly grease a 9×13 inch baking dish with cooking spray. This will prevent the Sweet Potato Casserole from sticking and help it brown evenly. Once your oven is ready, set the baking dish aside to begin prepping the sweet potatoes.
Step 2: Boil Sweet Potatoes
In a large pot, add the peeled and cubed sweet potatoes along with enough water to cover them. Bring the pot to a boil over high heat and let it cook for about 15-20 minutes, or until the sweet potatoes are fork-tender. Drain the potatoes and allow them to cool slightly before mashing for the casserole base.
Step 3: Mash the Sweet Potatoes
Transfer the drained sweet potatoes into a large mixing bowl. Add the unsalted butter into the bowl and use a potato masher or electric mixer to mash until smooth, leaving a few small chunks for texture. The mixture should be creamy and flavorful, setting the foundation for your Sweet Potato Casserole.
Step 4: Combine the Ingredients
Stir in the eggs, whole milk, light brown sugar, kosher salt, ground nutmeg, and pure vanilla extract into the mashed sweet potatoes. Mix thoroughly until all ingredients are well combined and the mixture is smooth. Once done, spread this delightful sweet potato mixture evenly into your prepared baking dish.
Step 5: Prepare the Pecan Topping
In a separate medium bowl, mix together the chopped toasted pecans, all-purpose flour, light brown sugar, and a pinch of salt. Melt the remaining unsalted butter and pour it over the topping mixture, then stir until it forms a crumbly, well-combined texture. This topping will add a lovely crunch to your Sweet Potato Casserole.
Step 6: Assemble and Bake
Sprinkle the pecan topping evenly over the sweet potato mixture in the baking dish. Ensure that the topping covers the sweet potato layer well, creating a golden crust when baked. Place the casserole in the preheated oven and bake for 25-30 minutes, or until the topping is golden brown and the casserole is heated through.
Step 7: Serve Warm
Once the Sweet Potato Casserole is done baking, remove it from the oven and let it cool for a few minutes. This will help the flavors meld beautifully while it cools slightly. Serve warm as a comforting side dish during your holiday feast, and prepare for the compliments to roll in!
