Instructions

To Make Potato Filling:

  • Start by peeling sweet potatoes. Dice into small cubes. Add diced sweet potatoes into a pan, pour ½ cup water and bring it to boil. Once starts boiling cover and cook on low flame until sweet potatoes are cooked through and tender. Will take around 12 to 15 minutes for potatoes to cook.
  • Drain off any liquids left in the pot. Rest sweet potatoes for few minutes. This will help remove any excess water from the potatoes.
  • Transfer cooked sweet potatoes into a bowl. Mash it using potato masher.
  • Add all ingredients – eggs, brown sugar, spices, vanilla and chopped pecans to the bowl.
  • Beat using hand blender or to mash until fluffy and well blended.
  • Grease casserole dish with butter on all sides. You can use cooking oil instead of butter to spray over the casserole dish.
  • Transfer potato filling into prepared casserole/baking dish. Set aside.

Sweet Potato Casserole Topping - To Make Streusel Topping (pecan crumb):

  • Into a food processor add pecans, light brown sugar, chilled butter(cubed), plain flour, spice powder and vanilla extract.
  • Pulse few times until the crumble mixture resembles pea-sized crumbs.

Bake:

  • Spread pecan crumb topping evenly over potato filling.
  • Bake in pre-heated oven at 375 degree Fahrenheit for 25 to 35 minutes until golden brown.

Marshmallow Topping:

  • Remove baked sweet potato casserole from the oven. Spread mini marshmallows in single layer. Bake in oven for 5 to 10 minutes. If desired you can broil for 1 or 2 minutes. Make sure not to broil longer, marshmallows will burn quickly.
  • Serve immediately.

Notes

  1. Do not use too much water while cooking sweet potatoes. ½ cup would do and remember to drain off all excess water before mashing sweet potatoes. Any liquids left in sweet potatoes will make the potato filling runny.
  2. Rest cooked potatoes for few minutes to get rid off excess water before mashing.
  3. You can use canned sweet potatoes for convenience, but I haven’t experimented with it!
  4. Feel free to use any of your favorite spice. Choose one or use a mix. I love cinnamon, clove and nutmeg spice mix. It gives the casserole a nice warming fall flavors!
  5. Choose one topping either streusel crumb or mini marshmallows. Double topping is highly recommended if you in mood for holiday indulgence.
  6. If you choose to broil marshmallows, broil only for 1 or 2 minutes. Marshmallows will burn quickly.
