Sweet Potato Soufflé Recipe
Sweet potato soufflé is a classic Southern casserole. This side transforms sweet potatoes into a creamy, light, and delicately spiced dish. This souffle is often served at Thanksgiving, but you can enjoy it any time you crave a comforting side with a touch of sweetness.

Sweet potatoes are whipped and blended until silky smooth, then folded with eggs, butter, and warm spices like cinnamon and nutmeg. It’s then topped with a crunchy topping, often brown sugar and pecans, baking up golden and slightly crisp.
You can add coconut, raisins, ginger, or even vanilla into the mix for extra layers of flavor. I love how versatile it is. You can enjoy it warm from the oven, and leftovers are always welcome for breakfast the next day.
This dish pairs well with roasted meats, such as turkey or ham, making it a staple for holiday feasts. For lighter fare, the soufflé brings balance when served next to sautéed green beans, creamed spinach, or a fresh arugula salad.
It also complements other classic sides like cornbread, wild rice pilaf, or buttery mashed potatoes. For a more elevated presentation, it sits beautifully beside a whole roast chicken, beef tenderloin, or grilled salmon. You can serve it for brunch with breakfast sausages, scrambled eggs, or a simple fruit salad.
