Ingredients
  

Main Ingredients

  • 4 lb sweet potatoes (6–7 large), peeled and cut into 1-inch cubes
  • 4 pieces eggs, beaten
  • 1 cup milk Use half-and-half for a richer filling.
  • 1/4 cup butter, melted (for filling)
  • 1 tsp vanilla extract
  • 3/4 cup white sugar Adjust to taste for sweetness.
  • 1 1/2 tsp salt

Optional Ingredients

  • 1–2 tsp cinnamon For warm spice.
  • 1 pinch nutmeg
  • 1 tsp orange zest For brightness.
  • 1 cup mini marshmallows If you want a classic twist.

Streusel Topping

  • 1/2 cup packed brown sugar
  • 1/3 cup flour Or use a 1:1 gluten-free blend.
  • 1/4 cup butter, chilled and cubed
  • 1 cup chopped pecans Can be substituted with walnuts.

Instructions
 

Preparation

  • Add sweet potato cubes to a large pot and cover with water.
  • Bring to a boil, then cook until fork-tender, about 20–25 minutes.
  • Drain well and mash until smooth (or leave a few small lumps if you like a rustic texture).

Mixing / Assembling

  • Preheat oven to 350°F.
  • In a large bowl, combine mashed sweet potatoes, beaten eggs, milk, melted butter, vanilla, white sugar, and salt.
  • Mix until smooth and creamy. Transfer to a 3-quart baking dish and spread evenly.

Cooking / Baking

  • Make the streusel: mix brown sugar and flour in a bowl.
  • Add chilled butter and cut it in using a pastry blender (or pinch with fingertips) until it looks like coarse crumbs.
  • Stir in chopped pecans.
  • Sprinkle topping evenly over the sweet potato layer.
  • Bake 45–50 minutes, until hot throughout and the topping is lightly browned.

Resting / Finishing

  • Let casserole cool for 10–15 minutes before serving so it sets slightly and slices cleaner.
  • Serve warm.

Notes

Tip for best texture: Drain sweet potatoes thoroughly—extra water can make the filling loose. Can be assembled in advance and refrigerated for up to 24 hours before baking.
