This Recipe Serves 12


Cooking Spray
3 lbs whole sweet potatoes, washed and dried
¼ cup Splenda Brown Sugar Blend
¼ cup low sugar (or freshly squeezed) orange juice
½ teaspoon salt (optional)
¼ cup ground flax seed
½ cup shelled walnut pieces
2 Tbsp Splenda Brown Sugar Blend
2 Tbsp Smart Balance Buttery Spread Original
6 egg whites
¼ teaspoon cream of tartar


  1. Preheat oven to 400 degrees Fahrenheit. Coat a deep 8-inch round or square casserole dish with cooking spray. Set aside.
  2. Coat a baking sheet with cooking spray. Arrange the washed and dried, whole sweet potatoes (with the skins on) on the sheet and coat generously with cooking spray. Bake for 50-60 minutes or until tender (check if they are tender by spearing the largest one with a paring knife or fork).
  3. Remove sweet potatoes from the oven and peel the skin. In a large bowl, whisk (or blend with a mixer) the roasted sweet potatoes with ¼ cup Splenda Brown Sugar Blend, orange juice and salt (optional). Set aside to cool.
  4. Using a food processor or chopper, grind the walnuts, flax seed and 2 tablespoons Splenda Brown Sugar Blend together until it is the consistency of wet sand. Add the Smart Balance Buttery Spread to the mixture in the food processor and pulse to incorporate (do not overmix this or it will turn into a paste). Set aside.
  5. Combine egg whites and cream of tartar in a large glass or metal bowl, and beat with an electric mixer on medium speed or with stand mixer using the whisk attachment until egg whites form soft peaks with tips that curl over when the beaters are lifted.
  6. Working in batches, incorporate one third of the egg whites into the sweet potato mixture using a large flat rubber spatula and gently folding them in until combined. Repeat that process two more times until all of the egg whites are incorporated into the sweet potatoes.
  7. Pour sweet potato soufflé mixture into the prepared casserole dish and top with the walnut mixture.
  8. Place the soufflé into the oven and bake at 400 degrees Fahrenheit for 20 minutes, then turn the oven down to 350 degrees Fahrenheit and continue to bake for 15 more minutes. Serve hot. (Note: the soufflé may deflate a little bit after baking so it’s best served immediately but is still okay to hold in a warming oven for service).

Chef Tip: Try not to open the oven at all during the baking process or your soufflé may not rise as high as it should.
