This sweet potato casserole is sprinkled with a nutty crumb topping to create a pleasantly crunchy contrast to the creamy and soft mashed sweet potatoes down below. The filling gets an extra special pumpkin pie(ish) treatment with brown sugar and vanilla for a deep caramel flavor. (In fact, leftovers can be heated up and topped with a scoop of ice cream just like pie.) Want to make ahead for Thanksgiving or another special holiday? Not a problem. The casserole ingredients can be mixed and transferred to a baking dish. Cover and refrigerate until ready to bake but leave off the topping. Store it separately at room temperature in an air-right container and sprinkle it on right before baking.
1. For the creamiest texture, ensure sweet potatoes are cooked until very tender and mashed thoroughly, or even passed through a ricer for ultimate smoothness. However, a slightly rustic mash can also add character.2. Do not overmix the filling once the eggs are incorporated; whisk just until combined to maintain a tender texture.3. While the recipe suggests pecans, feel free to experiment with walnuts or even a mix of nuts for the topping. A touch of cinnamon or nutmeg can enhance the 'pumpkin pie-ish' flavor.4. For advanced preparation, bake the casserole until just set, then cool completely and refrigerate. Reheat gently, adding the topping just before the final bake to ensure its crunch.
