This Maple Pecan Sweet Potato Casserole has been my go-to side for holiday dinners and lazy Sunday suppers for years. I first stumbled upon this combination during a chilly November when I wanted something both familiar and a touch more sophisticated than the usual marshmallow-topped casserole. The maple syrup softens the edge of sweetness while the brown sugar and spices coax out the natural caramel notes in the potatoes. The pecan streusel provides a contrasting crunch that keeps each bite interesting.

I remember the first time I brought this to a family reunion: my aunt asked for the recipe on the spot, and my cousin declared it “better than dessert.” The texture is what I adore most — silky, slightly whipped sweet potato beneath a nutty, buttery crust that browns beautifully in the oven. It’s forgiving to make, feeds a crowd, and keeps well, so it’s become my reliable contribution to any potluck or holiday table.

Ingredients

• Sweet potatoes (2 pounds): Choose firm, evenly sized sweet potatoes with smooth skin. Beauregard or Garnet varieties work well for a moist, sweet mash. Aim for about 2 pounds peeled and cubed to fit a 9×13 baking dish.
• Unsalted butter (1/2 cup melted + 1/4 cup cold): Use high-quality butter for flavor. Melted butter enriches the mash while the cold butter cut into the topping creates flaky crumbs.
• Pure maple syrup (1/2 cup): Opt for Grade A amber or pure maple syrup for a clear, sweet maple note. Avoid imitation syrups that can taste cloying.
• Light brown sugar (1/2 cup + 1/4 cup): The molasses in light brown sugar complements the maple and adds a soft caramel tone. Pack the sugar when measuring the topping amount.
• Ground cinnamon and nutmeg: A teaspoon of cinnamon and 1/2 teaspoon nutmeg add warm spice — freshly grated nutmeg is especially aromatic.
• Salt (1/4 teaspoon): Small but crucial — salt brightens and balances the sweetness.
• Pecans (1 cup chopped): Use toasted pecans if possible for extra depth; chop them coarsely so the topping retains bite and texture.
• All-purpose flour (1/4 cup): Helps bind the topping; for a gluten-free version, substitute with a 1:1 gluten-free flour blend.

Instructions

Preheat and prepare: Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with butter or nonstick spray. Having the oven at temperature before the casserole goes in ensures an even golden crust on the topping. Cook the sweet potatoes: Place the peeled, cubed sweet potatoes in a large pot and cover with cold water. Bring to a gentle boil and cook until tender when pierced with a fork, about 15–20 minutes depending on cube size. Drain thoroughly and return to the pot to steam-dry for a minute to avoid watery mash. Mash and flavor: In a large bowl, mash the sweet potatoes until mostly smooth but with a little texture remaining. Stir in 1/2 cup melted unsalted butter, 1/2 cup pure maple syrup, 1/4 cup packed light brown sugar, 1 teaspoon ground cinnamon, 1/2 teaspoon ground nutmeg, and 1/4 teaspoon salt. Taste and adjust seasoning; you want a warm, slightly sweet base that’s not cloying. Assemble the filling: Transfer the sweet potato mixture into the prepared 9×13-inch dish, spreading it to an even layer. Smooth the top with a spatula to create a consistent surface for the topping. Make the pecan topping: In a medium bowl, combine 1 cup chopped pecans, 1/4 cup all-purpose flour, and the remaining 1/4 cup packed light brown sugar. Add the 1/4 cup cold unsalted butter cut into small pieces. Using a pastry cutter or your fingertips, work the butter into the dry ingredients until the mixture resembles coarse crumbs with some pecan pieces still visible. Top and bake: Evenly sprinkle the pecan crumb mixture over the sweet potato layer so the topping covers the surface. Bake in the preheated oven for 30–35 minutes, or until the topping is golden brown and the casserole is heated through. If the topping browns too quickly, tent loosely with foil for the final 10 minutes. Rest and serve: Let the casserole rest for 5–10 minutes after removing from the oven. This helps the filling settle so portions hold their shape when served.

Storage Tips

Store leftovers in an airtight container in the refrigerator for up to 4 days. For the best texture, separate the pecan topping from the filling if possible; keep the crumble in a paper towel-lined container to absorb excess moisture. To freeze, assemble the entire dish, wrap tightly in plastic wrap followed by foil, and freeze for up to 3 months. Thaw overnight in the refrigerator before baking at 350°F for 20–30 minutes. Reheat single portions in the microwave, then flash-broil for a minute under the broiler if you want to crisp the topping again.

Ingredient Substitutions

If you need dairy-free options, substitute the butter with a vegan stick margarine measured 1:1; use a vegan sugar if required. For a gluten-free version, replace the all-purpose flour in the topping with an equal amount of almond flour or a gluten-free 1:1 baking flour — note that almond flour yields a more tender crumble and toasts faster. If pecans are unavailable, chopped walnuts or toasted hazelnuts work well, though the flavor profile shifts slightly. To reduce sugar, cut the brown sugar in the filling by half and rely on the maple syrup for sweetness; adjust spices to taste.

Serving Suggestions

This pairs beautifully with roasted turkey, glazed ham, or simply alongside a green salad for a lighter meal. Garnish with a few toasted pecan halves and a thin drizzle of maple syrup for presentation. Serve warm with a dollop of plain Greek yogurt or crème fraîche if you want a tangy counterpoint to the sweetness. For a holiday buffet, present in a shallow baking dish and accompany with cranberry relish and roasted vegetables to create a balanced plate.

Cultural Background

Sweet potato casseroles have deep roots in American holiday traditions, particularly in the South and Midwest, where sweet potatoes are a winter staple. The addition of a nutty streusel or marshmallows varies regionally; the maple-pecan combination leans into New England’s maple heritage and the Southern love of pecans. Over the years, home cooks have blended these regional influences to create comforting variations that reflect local ingredients and family tastes.

Seasonal Adaptations

In winter, add a pinch of ground cloves and cardamom for a warming spice mix; in autumn, fold in half a cup of roasted, diced apples for a fruitier profile. For a spring or summer twist, lighten the topping by using panko mixed with chopped pecans and a touch of lemon zest to brighten the flavors. During the holidays I sometimes sprinkle a few flaky sea salt crystals on top right before serving to highlight the sweetness.

Meal Prep Tips

Make the filling up to two days ahead and refrigerate in an airtight container. Prepare the topping and store it separately in the fridge; bring both to room temperature before assembling to ensure even baking. For single-serve meal prep, portion into individual ramekins, freeze, and reheat when needed. Label containers with date and reheat instructions to streamline weeknight dinners or holiday reheats.

There’s something deeply satisfying about sharing a dish that invites compliments and seconds. This Maple Pecan Sweet Potato casserole is adaptable, forgiving, and reliably delicious — give it a try at your next gathering and make it your own with the topping or spice adjustments you love most.
