Step‑by‑Step Instructions for Creamy Sweet Potato Casserole with Pecan Streusel
Step 1: Preheat the Oven
Start by preheating your oven to 350°F (175°C). While the oven warms up, take a moment to grease a 9×13-inch baking dish with a bit of butter or cooking spray to ensure that your creamy sweet potato casserole doesn’t stick. This will set the stage for an easy cleanup later.
Step 2: Prepare the Sweet Potatoes
Peel and cut the sweet potatoes into 1-inch cubes. Place them in a large pot, cover with water, and bring it to a boil over medium-high heat. Allow the sweet potatoes to cook for about 15 minutes, or until they are fork-tender. Once done, drain the water and let them cool for a few moments before mashing.
Step 3: Make the Sweet Potato Filling
In a spacious mixing bowl, combine the drained sweet potatoes with brown sugar, melted unsalted butter, vanilla extract, cinnamon, salt, and nutmeg. Using a potato masher or an electric mixer, mash the mixture until it achieves a smooth, creamy consistency. This mixture will form the delicious base for your Sweet Potato Casserole.
Step 4: Assemble the Casserole
Transfer the sweet potato mixture into the prepared baking dish. Use a spatula to spread it evenly, creating a nice, level surface. Take your time to ensure the mix fills all corners, as this will help with even cooking and presentation. Your casserole is now ready for its delightful topping.
Step 5: Prepare the Pecan Topping
In a medium bowl, combine melted butter, brown sugar, flour, and the chopped pecans. Stir until everything is well mixed and forms a crumbly texture. This tasty pecan streusel will add a lovely crunch that complements the creamy filling of your casserole beautifully.
Step 6: Top and Bake
Evenly sprinkle the pecan mixture over the mashed sweet potatoes in the baking dish. Place the casserole in the preheated oven and bake for 25-30 minutes, or until it’s hot and bubbly, and the pecans have turned golden brown. Watch closely as this will ensure your Sweet Potato Casserole has a delicious, toasted topping.

Sweet Potato Casserole Recipe FAQs
How do I choose the right sweet potatoes?
Absolutely! Look for sweet potatoes that are firm, with smooth skin and no dark spots. Avoid those with blemishes or soft spots, as they may be overripe or spoiled. A good sweet potato should feel heavy for its size and have a vibrant orange color.
Can I make this casserole in advance?
Yes, you can! You can prepare the sweet potato filling a day ahead. Simply cover it tightly and refrigerate it. When you’re ready to bake, let it sit at room temperature for about 30 minutes before adding the pecan topping and placing it in the oven. This saves you time on busy holiday mornings!
How do I store leftover sweet potato casserole?
After enjoying your meal, let the casserole cool completely. You can store leftovers in an airtight container in the refrigerator for up to 3 days. If you want to keep it longer, wrap it tightly in plastic wrap, then in foil, and freeze for up to 3 months. When you reheat, make sure to do so in a preheated oven at 350°F until heated through and creamy!
What if my casserole is too dry after baking?
Very good question! If this happens, it might mean you’ve overbaked it. To remedy it while baking, you can cover the dish with foil for the first 20 minutes to keep moisture in. If leftovers seem dry, try adding a splash of milk or a drizzle of melted butter while reheating to revive that creamy texture.
Is this casserole suitable for my kids or anyone with nut allergies?
Yes, but be cautious! Traditional pecan toppings may not be suitable for those with nut allergies. You can create a nut-free version by simply leaving out the pecans and using crushed graham crackers or oats as a topping instead. This still provides a delightful texture without any nut worries.
Can I freeze the sweet potato casserole before baking?
Of course! To freeze before baking, assemble the casserole but do not top it with the pecan mixture. Wrap it tightly in plastic wrap or aluminum foil and store it in the freezer for up to 3 months. When you’re ready to bake, thaw it in the refrigerator overnight, add the pecan topping, and bake as usual! This makes it super convenient for your holiday preparations.
