• ½ cup granulated sugar
• ¼ cup light brown sugar, packed

• ½ cup milk (whole milk preferred)
• 2 teaspoons vanilla extract
• 1 teaspoon ground cinnamon

How to Make Sweet Potato Casserole With Pecans

Preparing the Sweet Potato Base

• Preheat your oven to 375°F and lightly grease a 9×13 inch baking dish.
• Wash sweet potatoes and poke several times with a fork. Place directly on middle oven rack with a foil-lined baking sheet on the rack below (to catch drips).
• Bake sweet potatoes for 45-60 minutes until very tender when pierced with a fork.
• Allow potatoes to cool until you can handle them, then remove skins and place flesh in a large mixing bowl.
• Mash sweet potatoes until smooth (or use a food processor for extra smoothness).
• Add sugars, eggs, melted butter, milk, vanilla, cinnamon, nutmeg, and salt to the mashed sweet potatoes.
• Mix until well combined and smooth.
• Spread mixture evenly in the prepared baking dish.

Creating the Perfect Pecan Topping

• In a medium bowl, combine brown sugar, flour, chopped pecans, salt, and optional cinnamon.
• Pour melted butter over the mixture and stir until everything is moistened and crumbly.
• Evenly sprinkle the pecan mixture over the sweet potato layer.
• At this point, you can either bake immediately or refrigerate for baking later (perfect for make-ahead sweet potato casserole planning).
• Bake at 350°F for 30-35 minutes until the topping is golden brown and the casserole is heated through.
• Allow to rest for 5-10 minutes before serving.

Storage & Reheating Tips

Proper Storage Methods

This southern sweet potato casserole stores beautifully, making it perfect for holiday meal prep. After cooking, allow the casserole to cool completely before covering with aluminum foil or transferring leftovers to airtight containers. Refrigerated sweet potato casserole will maintain its quality for 3-4 days.

For longer storage, you can freeze this dish either before or after baking. If freezing unbaked casserole, prepare the sweet potato base and topping separately, freezing the base in the baking dish and the topping in a separate container. Thaw both in the refrigerator overnight before assembling and baking. For baked casserole, freeze in portion-sized containers for up to 3 months.

Best Practices for Reheating

When reheating refrigerated sweet potato casserole with pecans, cover with foil and warm in a 325°F oven for about 15-20 minutes until heated through. Remove the foil for the last few minutes to re-crisp the topping.

For frozen leftovers, thaw overnight in the refrigerator before reheating. If reheating from frozen, cover with foil and bake at 325°F for 30-40 minutes, then uncover and bake for an additional 5-10 minutes to restore the crunch to the pecan topping.

Microwave reheating works in a pinch, but the topping won’t maintain its crispness. To improve texture when microwaving, heat individual portions on 70% power in 30-second increments until warmed through.
