The filling
2 cups boiled sweet potato flesh (about 3 large), 3/4 cup brown sugar, 1/2 cup melted butter, 3 eggs, 1 cup evaporated milk, 1 tablespoon vanilla, 1 teaspoon cinnamon, 1/2 teaspoon nutmeg, pinch salt.
The crust
Pre-made deep-dish pie crust is fine — most Black grandmothers used Pillsbury. Don't overthink it.
Bake
375°F for 50–60 minutes. Center should be set but still slightly jiggly. Cool 2 hours before slicing.
Don't compare to pumpkin pie
It's a different dessert. Treat it as such.
