-
1/2 cup brown sugar, packed
-
1/4 cup granulated sugar
-
1/4 cup milk
-
2 large eggs, beaten
-
1 teaspoon vanilla extract
-
1/2 teaspoon ground cinnamon
-
1/4 teaspoon ground nutmeg
-
1/4 teaspoon salt
-
1 cup chopped pecans
-
1/4 cup all-purpose flour
-
1/4 cup brown sugar (for topping)
-
2 tablespoons unsalted butter, softened
Pro Tips
-
Choose the Right Sweet Potatoes – Opt for firm, evenly sized sweet potatoes for consistent cooking. Starchy varieties work best for a creamy texture.
-
Mash Properly – For a smooth casserole base, mash the sweet potatoes thoroughly and ensure no lumps remain before mixing with eggs and butter.
-
Layer Topping Strategically – Mix the pecans, flour, and brown sugar thoroughly and sprinkle evenly over the sweet potatoes. This prevents uneven baking and ensures every bite has a crunchy top.
Instructions
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with butter or nonstick spray. This ensures the casserole doesn’t stick and helps the topping brown evenly.
Step 2: Boil the Sweet Potatoes
Place peeled and cubed sweet potatoes in a large pot. Cover with water and add a pinch of salt. Bring to a boil and cook until fork-tender, about 15-20 minutes. Drain thoroughly.
Step 3: Mash the Sweet Potatoes
Transfer cooked sweet potatoes to a large mixing bowl. Add melted butter, brown sugar, granulated sugar, milk, beaten eggs, vanilla extract, cinnamon, nutmeg, and salt. Mash with a potato masher or hand mixer until smooth and creamy. Taste and adjust sweetness if needed.
Step 4: Prepare the Pecan Topping
In a small bowl, combine chopped pecans, brown sugar, flour, and softened butter. Mix until crumbly but evenly coated. The mixture should resemble coarse sand.
Step 5: Assemble the Casserole
Spread the mashed sweet potato mixture evenly in the greased baking dish. Sprinkle the pecan topping evenly over the sweet potatoes, pressing lightly to help it stick.
Step 6: Bake
Bake in the preheated oven for 25-30 minutes, until the topping is golden brown and crispy. A toothpick inserted into the sweet potatoes should come out clean.
Step 7: Cool and Serve
Allow the casserole to cool slightly before serving. This helps the topping set and makes slicing easier. Serve warm with your favorite holiday dishes or family dinner favorites.
Variations
-
Marshmallow Topping – Replace the pecan topping with mini marshmallows for a sweeter, gooey version.
-
Vegan Adaptation – Substitute butter with coconut oil and use a plant-based milk to make this casserole vegan-friendly.
-
Spiced Delight – Add ginger or allspice to the sweet potato mash for a deeper, aromatic flavor.
Storage/Serving
Storage: Refrigerate leftovers in an airtight container for up to 4 days. Reheat in the oven at 325°F (160°C) for 10-15 minutes to restore crispiness.
Serving Suggestions:
-
Pair with roasted turkey or baked ham for a traditional Southern feast.
-
Serve alongside garlic green beans or cranberry sauce for color and flavor contrast.
-
Top with a dollop of whipped cream or vanilla ice cream for a dessert-like twist.
