Preheat your oven to 350°F.
Prepare a 2-quart baking dish or a 9-inch square pan by greasing it with non-stick spray.
In a mixing bowl, combine the cooked sweet potatoes, granulated sugar, softened butter, eggs, salt, and vanilla extract.
Beat the mixture until it is smooth and creamy.
Transfer the sweet potato mixture into the prepared baking dish, spreading it evenly.
In a separate bowl, mix together the brown sugar, flour, chopped pecans, and melted butter until the mixture becomes crumbly.
Evenly sprinkle the crumbly topping over the sweet potato mixture.
Bake the casserole uncovered for 35 minutes, or until it is bubbly and the topping has turned golden brown.
Allow the casserole to rest for 10 minutes before serving.

Bake sweet potatoes ahead on a roasting sheet and refrigerate to save time. You can swap pecans for walnuts if needed.
