Sugar-Free Sweet Potato Casserole With Pecan Topping

Photo © Andrea Skjold

This casserole is also called Sweet Potato Crunch because of the crunchy pecan topping.

Although no one is going to call sweet potatoes (also known as yams) low in carbohydrate if you follow a moderate-carb diet, or indulge in an occasional higher-carb treat, sweet potatoes are a great choice. They are packed with nutrients, and have a lower glycemic index than regular white potatoes (although I know people who track their blood glucose who disagree). This sweet potato casserole has no added sugars, but because sweet potatoes have different consistencies and levels of sweetness, you may need to adjust a bit. I used garnet yams when developing the recipe. (P.S. Want a very simple and delicious way to serve yams? Just bake them like a potato and eat with butter.)


  • 3 lbs sweet potatoes (try to find ones that are about the same size)
  • 1½ cups pecan pieces
  • 2 teaspoons cinnamon
  • ½ teaspoon nutmeg
  • 1 teaspoon salt
  • ¼ teaspoon pepper
  • 5 Tablespoons butter
  • 1 egg
  • Sugar substitute


1. Poke the sweet potatoes/yams several times with a sharp knife and roast at 400 F. until soft - about 45-60 minutes depending upon the size.

2. Make the topping - pulse 1 cup of the pecans in food processor or blender until it is ground into a meal. Add about 1/4 cup worth sugar substitute, 1 teaspoon cinnamon, a pinch of salt, and 2 Tablespoons of the butter and process until blended. Mix the rest of the pecan pieces in by hand.

3. Let the sweet potatoes cool for 10-15 minutes. Split them and remove the pulp. Put them into the food processor or blender (no need to wash between topping and sweet potatoes) and process with the rest of the butter (3 Tablespoons). Mashing with a potato masher is also fine, but the texture will be somewhat smoother if you blend/process. Add the rest of the seasonings (1 teaspoon cinnamon, the nutmeg, salt, and black pepper). The amount of sweetener you add will be up to your taste and the sweetness of the yams. When the seasonings are to your taste, add the egg and blend.

4. Put sweet potatoes in a buttered baking dish and sprinkle pecan topping over the top. Bake at 375 F. until the topping is browned.

I loved this but I've found a sub that's great, Guest eve

I bake butternut squash, mash it with cream cheese and butter and a little sugar and vanilla. We like it even better than the sweet potato. Put a little brown sugar (sf if you can find it) some chopped pecans, a little chopped butter and it is just as good as the traditional. I still like this one though because it is easier and will prob make it from time to time.
