Casseroles are a fall and holiday table staple — comforting, easy to make ahead, and perfect for feeding a crowd. In this post, we’re sharing a detailed recipe for sweet potato casserole with a crunchy pecan streusel topping, along with a roundup of other fall casseroles worth adding to your table.
Why Sweet Potato Casserole Is a Fall Favorite
This casserole combines a smooth, lightly spiced sweet potato base with a buttery, crunchy pecan streusel topping, striking a perfect balance between savory and sweet. It’s a classic Thanksgiving side, but easy enough to make for any fall dinner.
Ingredients
For the sweet potato base
- 4 lbs sweet potatoes, peeled and cubed
- ½ cup unsalted butter, softened
- ½ cup packed brown sugar
- 2 large eggs
- ½ cup milk
- 1 teaspoon vanilla extract
- ½ teaspoon ground cinnamon
- ¼ teaspoon salt
For the pecan streusel topping
- 1 cup chopped pecans
- ½ cup packed brown sugar
- ⅓ cup all-purpose flour
- ¼ cup unsalted butter, melted
- ¼ teaspoon salt
Equipment
- A large pot
- A 9×13-inch baking dish
- A hand or stand mixer
- A mixing bowl
Instructions
Step 1: Cook the sweet potatoes
Boil the cubed sweet potatoes in salted water for 15-20 minutes, until fork-tender. Drain well.
Step 2: Mash the base
In a large bowl, beat the drained sweet potatoes with a hand mixer until smooth. Add the softened butter, brown sugar, eggs, milk, vanilla extract, cinnamon, and salt, beating until well combined.
Step 3: Assemble
Preheat your oven to 350°F (175°C). Spread the sweet potato mixture into a greased 9×13-inch baking dish.
Step 4: Make the streusel topping
In a bowl, combine the chopped pecans, brown sugar, flour, melted butter, and salt, mixing until evenly moistened and crumbly.
Step 5: Top and bake
Sprinkle the streusel topping evenly over the sweet potato base. Bake for 30-35 minutes, until the topping is golden brown and the filling is heated through.
Step 6: Cool slightly and serve
Let the casserole rest for about 10 minutes before serving.
Tips for the Best Sweet Potato Casserole
- Boil the sweet potatoes until very tender for the smoothest mashed base.
- Assemble ahead of time and refrigerate, adding the streusel topping just before baking, for an easy make-ahead side.
- Toast the pecans first for extra flavor in the topping, if you have time.
- Adjust the sweetness by reducing the brown sugar in the base if you prefer a less sweet side dish.
Storage
Store leftover casserole covered in the refrigerator for up to 4 days. Reheat in the oven at 350°F until warmed through.
