Lightened Sweet Potato Casserole Recipe for Holiday Gatherings

My Sweet Potato Casserole Lightened Up keeps the rich brown sugar and buttery notes of a classic casserole while cutting roughly half the calories.

Sweet Potato Casserole is my favorite Thanksgiving side. Served alongside a vegetable casserole, steamed green beans and whole-wheat rolls, it steals the show. I’ll happily skip gravy if I can have a generous helping of this casserole.

Who doesn’t love a dish that tastes like dessert with dinner?

In high school and college, my friend Julia brought a legendary sweet potato casserole to our Thanksgiving dinners. It was loaded with butter and brown sugar and absolutely irresistible.

When I asked Julia for the recipe while planning my first Thanksgiving as a host, I was surprised by how much butter and sugar it called for. With my husband’s help, I set out to lighten it while keeping the flavor intact.

This isn’t a “health” casserole, but it’s noticeably less indulgent than the original. Most of the calorie savings come from cutting back the butter and sugar in the filling. I kept the topping rich — it’s the heart of the experience — though you could reduce the sugar there and add more oats or flour if you prefer.

The casserole still delivers brown sugar flavor in every bite without being overly sweet. Toasting the pecans deepens their flavor and helps them stay a bit crunchier, even after chilling. With less butter and sugar in the filling, the natural sweetness of the sweet potatoes comes forward more, reminding you how good they are on their own.

I originally planned to layer thinly sliced potatoes, but I overcooked them and they didn’t hold their shape. Pureeing the filling worked beautifully and is an easy fallback if slices fall apart.

Mashed filling tastes just as delicious even if it isn’t as visually layered — sometimes flavor is more important than looks.
