Duo Tater Bake truly has an accurate name: it’s a potato casserole that features two very different spuds! Layers of classic potatoes alternate with layers of sweet potato, both of which are mashed in a creamy, tangy, herbaceous sauce. Throw in some melty sharp cheese and a few green onions and you have the best mashed potato bake you could hope for. This makes sense, since Duo Tater Bake is basically all the greatest hits of mashed potato playing all at once on your tastebuds. Ordinary mashed potatoes don’t feel so exciting anymore when you know you could double the flavor at any time!
