Ingredients

Scale

Main Ingredients:

  • 3 lbs sweet potatoes
  • 2 large eggs
  • 1 cup brown sugar
  • 6 tablespoons melted butter
  • ¼ cup half-n-half

Supporting Ingredients:

  • ⅓ cup all-purpose flour
  • 2 teaspoons vanilla extract
  • 1 teaspoon cinnamon

Seasonings:

  • 1 teaspoon salt
  • 3 tablespoons salted butter

Instructions

  1. Pierce 3 lbs sweet potatoes with a fork and roast at 400°F for 50-60 minutes until completely soft. Let them cool slightly before handling.
  2. Scoop the roasted potato flesh into a large mixing bowl. Add 6 tablespoons melted butter, ½ cup sugar, 2 large eggs, 2 teaspoons vanilla, 1 teaspoon cinnamon, 1 teaspoon salt, and ¼ cup half-n-half.
  3. Blend the sweet potato mixture with a mixer until completely smooth and creamy. Your goal is a consistent texture without lumps.
  4. Transfer the mixture into a 9×13-inch baking dish. Smooth the surface evenly with a spatula to create a clean, level base.
  5. Make the streusel by combining 3 tablespoons softened butter, 1 cup brown sugar, and ⅓ cup flour in a small bowl. Mix with your fingers until the texture resembles coarse crumbs.
  6. Sprinkle the streusel topping uniformly across the sweet potato base, ensuring complete and even coverage.
  7. Reduce oven temperature to 350°F. Bake the casserole for 20-25 minutes until the top turns golden brown and the interior is heated through.
  8. Optional: Scatter mini marshmallows or chopped pecans over the streusel before the final baking for extra crunch and sweetness.

Notes

  • Roasting the sweet potatoes whole brings out deeper, richer flavor that makes the casserole more delicious.
  • Allow sweet potatoes to cool slightly before scooping out flesh to make handling easier and prevent burns.
  • When mixing the sweet potato base, blend thoroughly to create a smooth, creamy texture without lumps.
  • For a lighter version, swap half-and-half with whole milk and reduce sugar to cut calories while maintaining great taste.
