Skinny Sweet Potato Casserole Recipe
This Healthy Sweet Potato Casserole Recipe gets its sweetness and creaminess from low-fat vanilla yogurt instead of butter, cream and sugar.
When I finally tasted sweet potato casserole, I didn’t love it. I found it too sweet and kind of strange. That was a few years ago. These days I’m totally on board with it. So much so that my sister site is doing a whole series on sweet potatoes right now and featuring a lot of sweet potato casserole recipes. Head over here to check it out. My favorite recipe there is for these adorable little sweet potato casserole bites. They’re the top left picture in the collage below. Soooo tasty.
The goal for today’s recipe was to find a sweet potato casserole that both I and traditionalists will enjoy. This recipe is a touch less sweet than the classic. But you can add some extra brown sugar if you really need to. Check out the recipe below. It tells you when to taste it and when and how much sugar to add if you like it sweeter than I do.
This recipe also addresses my other concern about Sweet Potato Casserole: Even though I like it now, I’m never sure I want to have very much because I know that it’s loaded with butter and cream and MARSHMALLOWS! I’d much prefer to save my calories for the stuffing and gravy – oh, and the pumpkin pie of course!
I’ve played around with the basic recipe a bit to come up with something that’s just as creamy as the original but a bit healthier. This version doesn’t have any butter or cream. Instead, the creaminess comes from vanilla yogurt.
To further reduce the sugar in the recipe, I’ve tweaked the classic sweet potato casserole topping by cutting back on the marshmallows. The marshmallows are still there and their brown puffiness will please traditionalists. But they don’t cover the whole casserole in melted candy.
As for the Sweet Potato Casserole Topping: I have a trick for making sure that the marshmallows don’t get crunchy. First, you bake the casserole for awhile without the topping. Then you add the pecans and marshmallows and continue to bake just until the marshmallows are puffed softly and starting to brown. This ensures that the pecans don’t get overly dark and bitter as well.

And now, here’s my Healthy Sweet Potato Casserole recipe.
