Getting ready for another feast

I'm starting to think about what to cook for our family Christmas Eve party and I gravitate back to those delicious Thanksgiving side items.  This year I'll be making my sister's Sweet Potato Casserole since she won't be able to join us.  We will miss her!

Sweet Potato Casserole

3 cups mashed sweet potatoes (approx. 1 1/2 lb. fresh, boiled or baked, skin removed, mashed)
1 cup sugar (I use less if potatoes are sweet)
2 eggs, beaten
1/2 cup melted butter
1 tsp. vanilla
1/2 tsp. salt

Topping:
1 cup brown sugar
1/3 cup melted butter
1/3 cup all purpose flour
1 cup chopped pecans

Preheat Oven to 350 degrees.  Butter a 13"x9" baking dish.
In a large bowl, mix first 6 ingredients together (potatoes through salt) and pour into prepared dish.  In a separate bowl,  combine topping ingredients and sprinkle over casserole.  Bake 45 minutes.
