This Whipped Sweet Potato Mash with Maple, Pecan and Rosemary is the BEST sweet potato mash you will ever eat! I don't say that lightly, this dish is smooth, creamy, savory and sweet all at the same time. Pillowly delicious mashed sweet potato, topped with buttery maple syrup coated pecans and fragrant rosemary. This casserole is a must make Thanksgiving or Christmas side dish. Plus it is easy to make ahead and doesn't need any space in the oven! #thanksgivingsidedish #christmasrecipe
