I used to be such a mashed potato purist. Surely there couldn’t be any reason to fiddle with such a perfect side dish. Potatoes that have simply been mashed to a fluffy delight, topped with a pat of butter or better yet gravy. Perfection.
Cue this Make Ahead Mashed Potato Casserole. What I love about this recipe, is that it’s great for entertaining. The make ahead factor frees up a burner on the stove, and you’re not laboring over a big pot of potatoes and a potato masher while your guests are waiting for dinner.
It gets even more genius. Besides its deliciousness, it can be made the day before, or even two. Cook the potatoes, assemble the casserole, wrap tightly and store it in the refrigerator. When dinnertime comes, dust it with the cheese, butter and bread crumbs and toss it in the oven.
Speaking of the Holidays, got a foodie in your life that you’ll be shopping for? Besides yourself? Did you know Anthony Bourdain has a new cookbook out? His first in over a decade. And it’s not what you expect from Bourdain.
