I used to skip making mashed potatoes on Thanksgiving because I thought that you had to make them right before you served them. I had enough going on to worry about, and didn’t need another last minute item on the menu. A friend passed along her technique for making them in a casserole and I have never looked back. These are the smoothest, creamiest, most incredible mashed potatoes I have ever eaten.

I like to add some extra flavor and color by adding garlic and fresh chopped herbs. You can leave them plain if you like, but I really like the garlic. You can make these up to two days ahead of time. Cover the casserole with plastic wrap and let come to room temperature. Bake until the top browns and puffs up.
