About Sweet Potato Casserole

Sweet potato casserole is a classic American dish commonly served during Thanksgiving and Christmas. With roots in Southern cooking, it traditionally includes ingredients like butter, sugar, and often marshmallows, a touch that was popularized in the early 20th century as part of a marketing effort by a marshmallow manufacturer. Since then, it’s become a holiday staple, appreciated for its blend of sweet and savory flavors.

In many households, sweet potato casserole symbolizes comfort and tradition, representing the flavors of fall and holiday warmth. The pecan streusel is inspired by Southern baking traditions, adding a delightful crunch and nutty depth to the casserole. The addition of vegan marshmallows and plant-based butter allows those on a dairy-free, vegan diet to enjoy this holiday classic while still keeping true to the original spirit of the dish.
