A healthy sweet potato casserole with less sugar

This is the best healthy sweet potato casserole recipe! Unlike the traditional sweet potato casseroles loaded with cream, brown sugar, and marshmallows. This recipe is a healthier twist on a classic casserole. It’s made with a few simple ingredients that are healthier, and it still tastes great.

Since sweet potatoes are healthy, naturally sweet, and delicious, I don’t like to add a lot of sugar to them. Most times I bake them and serve them with a sprinkle of cinnamon or nutmeg.

When it’s the holidays, I like to dress them up a little bit which is what I’ve done with this sweet potato recipe.

I’ve found that all you need is a little bit of natural sweetener and warming spices to balance the flavor and allow the natural sweetness of the sweet potatoes to shine through. And that is also how I make my sweet potato fritters and ginger and garlic sweet potato mash.
