Ingredients Equipment Method Notes

Ingredients
  

  • 3 large sweet potatoes
  • 2 cups marshmallows
  • 1/4 cup vegan butter melted
  • 1/4 cup brown sugar or coconut sugar
  • 1 teaspoon cinnamon half to 1 depending on taste
  • 1/2 teaspoon salt
  • 1 teaspoon vanilla extract optional

Equipment

  • 8x10-inch baking dish (20x25-cm)
  • Chef’s knife and cutting board
  • Large pot
  • Measuring cups and spoons
  • Mixing bowls and spoons
  • Stand mixer or potato masher

Method
 

  1. Cook the sweet potatoes. Wash, peel, and roughly chop the sweet potatoes. Place in a large pot of water on the stove and boil until fork tender, about 30 minutes at a rolling boil. Drain and place into a large mixing bowl.
  2. Preheat the oven to 350°F/180°C. Make sure the oven rack is in the center of the oven.
  3. Combine. Mash the sweet potatoes using your stand mixer with the paddle attachment or with your hand masher. Add the vegan butter, brown sugar, cinnamon, salt, and optional splash of vanilla. Transfer to the baking dish and smooth the top down. Cover with marshmallows.
  4. Bake. Bake uncovered for 25 to 30 minutes or until the marshmallows are lightly browned on top. If they are browning too quickly, you can make a tent of aluminum foil. Just spray the foil first so the marshmallows don’t stick. Enjoy!

Notes

How to Store
Fridge: Store any leftover casserole in an airtight container for up to 4 days.
Freezer: After assembling, store the casserole in a freezer safe container for up to 2 months. Let it thaw in the fridge overnight before bringing the casserole to room temperature (so your baking dish doesn't break!) and baking as directed.
