Sharing my personal chef secrets for how I do mashed potatoes for clients so they reheat beautifully and stay light and fluffy. Make-Ahead Mashed Potatoes (Mashed Potato Casserole) are smooth, creamy, slightly cheesy, garlicky, a little bit tangy and a whole lot delicious.
Best of all, they can be made two days ahead and baked when you need them or two hours ahead and kept hot in your slow cooker!
