Ingredients for creamy buttery pecan sweet potato casserole recipe

• 3 lbs sweet potatoes
• 4 tbsp butter
• 1/2 cup heavy cream
• 1/4 cup brown sugar
• 1 tsp vanilla extract
• 1/2 tsp cinnamon
• 1/4 tsp nutmeg
• 1/4 tsp salt
• 1 cup pecans, chopped
• 3 tbsp butter
• 2 tbsp brown sugar
• 1/4 tsp salt
• 2 tbsp maple syrup

You can substitute the heavy cream with half-and-half if you prefer a lighter version, though the casserole won’t be quite as rich. If pecans aren’t available, walnuts or candied pecans work beautifully and add different flavor dimensions to your dish. For those with nut allergies, crushed gingersnap cookies mixed with melted butter create an unexpectedly delicious topping.

Make sure your sweet potatoes are similar sizes so they bake evenly and cook at the same rate. Roasting them in the oven rather than boiling preserves more flavor and creates a denser, more concentrated sweetness perfect for this recipe.

Step-by-step pecan sweet potato instructions

1. Preheat your oven to 350°F and line a baking sheet with foil. Pierce whole sweet potatoes several times with a fork and roast them for 40-45 minutes until completely tender and easily pierced. Remove from oven and let cool slightly until you can handle them comfortably.

2. Scoop the flesh from roasted sweet potatoes into a large mixing bowl, discarding skins. Mash with 4 tablespoons butter and heavy cream until smooth and creamy, then stir in vanilla extract and salt until combined thoroughly.

3. Add cinnamon and nutmeg to the sweet potato mixture, folding gently to distribute the spices evenly throughout. Stir in 1/4 cup brown sugar and taste, adjusting sweetness if needed for your preference.

4. Spread the creamy buttery pecan sweet potato casserole recipe into a buttered 9×13 baking dish, smoothing the top with the back of a spoon. In a small bowl, combine chopped pecans, 3 tablespoons melted butter, 2 tablespoons brown sugar, salt, and maple syrup until clumpy and fragrant.

5. Scatter the pecan topping evenly across the sweet potato layer, pressing gently so pieces adhere to the surface. Bake for 20-25 minutes until the topping turns golden brown and the filling is heated through completely.

6. Remove from oven and let rest for 5 minutes before serving, which allows flavors to settle and makes portioning easier.
