Soft whipped sweet potatoes layered under a toasted brown sugar pecan topping are an absolute essential at my family’s table whether it is for Thanksgiving or any other celebration. This Sweet Potato Casserole with Pecan Topping combines creamy, buttery potatoes with a crispy nutty crumble for crowd-pleasing comfort.
I have served this at many family gatherings and there is never a spoonful left. My youngest niece always sneaks the last crispy bits from the edges and it truly brings us all together.
Ingredients
- Canned sweet potatoes in syrup: for convenience and reliable sweetness look for cans with firm whole potatoes and avoid those too soft or broken
- Granulated sugar: for enhanced sweetness opt for fine baking sugar so it blends evenly
- Large eggs: provide body and help set the casserole use fresh eggs with firm whites for best texture
- Butter: adds rich flavor and moisture real unsalted butter gives the purest taste
- Half and half cream: creates luscious creaminess choose a fresh pint for the fullest flavor
- Vanilla extract: brings a hint of warmth and depth use pure vanilla if possible for a richer aroma
- Brown sugar: gives caramelized notes in the topping use dark brown sugar for intense flavor if you love molasses undertones
- Flour: binds the topping and keeps it crisp look for unbleached all-purpose flour
- Chopped pecans: deliver classic crunch toast them lightly if you prefer deeper flavor
- Ground cinnamon: infuses spicy warmth fresh cinnamon keeps the flavor noticeable
Step-by-Step Instructions
- Prep and Preheat:
- Set your oven to 350 degrees Fahrenheit so it is hot and ready. This ensures the casserole cooks evenly from the start.
- Whip the Sweet Potato Base:
- Combine the drained sweet potatoes with sugar, beaten eggs, room temperature butter, half and half, and vanilla in a large mixing bowl. Use an electric mixer to whip until smooth and creamy. You want all the sugar and butter fully incorporated without any lumps.
- Assemble in Baking Dish:
- Spoon the whipped mixture into your ungreased eight by eight inch baking dish. Spread it evenly using a spatula for a smooth base so the topping lays flat.
- Mix and Add the Topping:
- In a small bowl combine brown sugar, flour, and cinnamon using a fork so the cinnamon is well blended. Sprinkle this mixture in an even layer across the sweet potatoes. Distribute the chopped pecans on top then press down gently with your palm so they stick to the surface.
- Finish with Butter:
- Pour melted butter evenly over all the topping covering pecans and brown sugar as much as possible. This will help everything bake up golden and toasty.
- Bake and Rest:
- Place casserole in the center of your preheated oven. Bake for twenty five to thirty minutes until the edges are bubbling and the center feels set when lightly pressed. Take out and let it sit five to ten minutes so the topping firms up slightly.

Casserole keeps well covered in the fridge for up to four days. To reheat simply warm in a low oven until heated through this keeps the topping crisp. Avoid microwaving as the pecan topping will soften and lose its crunch.
Ingredient Substitutions
No canned sweet potatoes Use roasted fresh sweet potatoes cooled and mashed. If you are nut free swap pecans for rolled oats tossed with a splash of melted butter and sugar for a crisp but nut free topping.
Serving Suggestions
Serve as a savory sweet side with roasted turkey ham or even weeknight roasted chicken. This casserole also pairs wonderfully with crisp salads or roasted Brussels sprouts to balance out the richness.

Cultural and Historical Context
Sweet potato casserole is a staple on American Southern holiday tables believed to have evolved from colonial and African American culinary traditions. The sweet topping reflects a blend of influences and has become an iconic part of Thanksgiving for families around the country. For many the combination of marshmallow or pecan topping sparks passionate debate but this version remains my family standard.
