Sweet Potato Casserole

Healthy Sweet Potato Casserole

This is a Thanksgiving classic recipe that many people love. Our family prefers plain baked sweet potatoes with lots of butter and Himalayan salt, but since some extended family prefer the marshmallow dredged type, I decided concoct a healthy version.

Every time I’ve made this sweet potato casserole for family and friends, it’s been a huge hit. The “marshmallow” topping also makes a great cake icing on coconut flour cakes for kids’ birthdays. This is still pretty high in starch so it shouldn’t be eaten every day, but it is definitely a healthier alternative to the high-fructose corn syrup marshmallow version.

You can also leave off the marshmallows completely, or reduce the amount of gelatin in this marshmallow recipe to 3 tablespoons to make a marshmallow fluff topping.

  • Bake the sweet potatoes until soft.
  • Once slightly cooled, mash the sweet potatoes with butter or coconut oil and salt.
  • Grease a 9x13 inch baking dish with butter or coconut oil and fill with mashed sweet potatoes.
  • In a double boiler or small pan with water and a glass bowl on top, whip the egg whites with a hand blender until fluffy.
  • Add honey to the egg whites and place the double boiler on the stove, turning on heat to medium.
  • Use a whisk to whip the egg white and honey mix as it heats. Whisk for about 20 minutes (or less) until it thickens.
  • It will start to take on the consistency of melted marshmallows ... when it is thick enough, spread over the sweet potatoes and put in the oven and broil for a minute or two to brown.
  • Serve plain or with toasted pecans on top.


You could make the sweet potato part of this recipe ahead of time and reheat it in the oven while you're making the topping.
