Ingredients
  

Sweet Potato Mixture
  • 4 large sweet potatoes
  • 0.5 cup unsalted butter melted
  • 0.5 cup granulated sugar
  • 0.25 cup light brown sugar
  • 0.25 cup milk
  • 1 teaspoon vanilla extract
  • 0.5 teaspoon salt
Pecan Streusel Topping
  • 0.5 cup all-purpose flour
  • 0.5 cup light brown sugar
  • 0.25 cup unsalted butter cold, cut into cubes
  • 1 cup chopped pecans
  • 0.5 teaspoon ground cinnamon

Equipment

  • 9x13 inch baking dish
  • large pot
  • large mixing bowl
  • medium bowl
  • pastry blender (optional)

Method
 

Preparation
  1. Preheat your oven to 375°F (190°C) and lightly grease a 9x13 inch baking dish.
  2. Peel the sweet potatoes, cut them into 1-inch cubes, and boil them in a large pot of salted water until they are very tender, which usually takes about 15-20 minutes.
  3. Drain the sweet potatoes thoroughly, then transfer them to a large mixing bowl and mash them until smooth.
Assemble the Casserole
  1. Add melted butter, granulated sugar, brown sugar, milk, vanilla extract, and salt to the mashed sweet potatoes, mixing well until the mixture is smooth and creamy.
  2. In a separate medium bowl, combine flour, brown sugar, cold butter cubes, chopped pecans, and cinnamon for the streusel topping, mixing with your fingers or a pastry blender until a crumbly mixture forms.
  3. Spread the sweet potato mixture evenly into the prepared baking dish and then sprinkle the pecan streusel topping evenly over the sweet potato layer.
Bake
  1. Bake for 30-35 minutes, or until the topping is golden brown and the casserole is heated through.
  2. Let the casserole cool slightly before serving.

Notes

For an extra touch, you can add a pinch of nutmeg or allspice to the sweet potato mixture. If you don't have a pastry blender, you can use two knives to cut in the butter for the streusel topping.
