Ingredients for Make-Ahead Sweet Potato Casserole
Let’s break down what you’ll need for this flavorful holiday dish.
For the Sweet Potato Base:
-
4 large sweet potatoes (about 3 pounds) – Peeled, chopped, and cooked until tender.
-
½ cup unsalted butter (1 stick) – Adds rich, creamy flavor.
-
½ cup brown sugar (light or dark) – Brings warm caramel notes.
-
¼ cup maple syrup or honey – Enhances natural sweetness.
-
2 large eggs – Create structure and fluffiness.
-
½ cup milk or cream – For smooth texture (use dairy-free milk if needed).
-
1 teaspoon pure vanilla extract – Adds depth and aroma.
-
1 teaspoon cinnamon – Classic fall spice that enhances sweetness.
-
¼ teaspoon nutmeg – Optional, for extra warmth.
-
Pinch of salt – Balances the flavors.
For the Buttery Pecan Topping:
-
1 cup chopped pecans – Toasted for crunch and aroma.
-
½ cup brown sugar – For caramelized sweetness.
-
⅓ cup all-purpose flour – Binds the crumble. (Use oat or almond flour for gluten-free.)
-
3 tablespoons melted butter – To create a crisp topping.
-
½ teaspoon cinnamon – Optional, for extra spice.
How to Make It Step-by-Step
This casserole is simple to prepare in stages — perfect for planning ahead of your potluck or big family meal.
Step 1: Prepare and Cook the Sweet Potatoes
-
Peel and cut the sweet potatoes into even cubes.
-
Place them in a large pot of salted water and bring to a boil.
-
Cook for 15–20 minutes, until fork-tender.
-
Drain and let them cool slightly.
Pro Tip: For deeper flavor, roast the sweet potatoes instead. Bake whole sweet potatoes at 400°F (200°C) for 45–50 minutes, then scoop out the flesh. Roasting intensifies their natural sweetness.
Step 2: Make the Sweet Potato Filling
Mash the cooked sweet potatoes until smooth (use a potato masher, hand mixer, or stand mixer). Then stir in:
-
Melted butter
-
Brown sugar
-
Maple syrup
-
Milk
-
Eggs
-
Vanilla extract
-
Cinnamon, nutmeg, and salt
Mix until creamy and uniform, but don’t overmix — a slightly rustic texture adds charm.
Step 3: Prepare the Pecan Topping
In a medium bowl, combine brown sugar, flour, chopped pecans, cinnamon, and melted butter. Stir until crumbly and evenly coated.
This topping becomes golden, crisp, and buttery as it bakes — a perfect contrast to the creamy sweet potatoes underneath.
Step 4: Assemble the Casserole
-
Grease a 9×13-inch baking dish.
-
Spread the sweet potato mixture evenly into the dish.
-
Sprinkle the pecan topping evenly over the top.
-
Cover with plastic wrap or foil if making ahead.
Step 5: Make Ahead and Chill
You can now refrigerate your assembled casserole for up to 24 hours before baking.
When you’re ready to serve:
-
Remove from the refrigerator 20–30 minutes before baking to come to room temperature.
-
Preheat oven to 375°F (190°C).
-
Bake uncovered for 35–40 minutes, or until the top is golden brown and the edges are bubbling.
Make-Ahead Bonus: The flavors actually deepen overnight, making this dish even more delicious the next day!
Step 6: Serve and Enjoy
Once baked, let the casserole rest for 10 minutes before serving. This allows the topping to set and makes it easier to scoop.
Serve warm with your Thanksgiving turkey, glazed carrots, or cranberry sauce — or enjoy it solo as a cozy fall treat.
