This may be a Thanksgiving classic, but you’ll want it all fall and winter long. Use the Anova Precision Oven to cook your sweet potatoes in their skins for an easy peel-and-mash base. Top it with a mixture of pecan streusel and broiled marshmallows for a finish that isn’t too sweet and has a nice crispness that will keep you coming back for more! Baking the casserole with 50% steam keeps the interior moist.
