Scalloped Potatoes Alfredo

In saucepan, combine package Club House Pasta Prima Alfredo Sauce Mix with butter and milk. Bring to a boil over medium heat, whisking frequently. Reduce heat and simmer 3 minutes.

In 2 qt (2 L) lightly greased microwave-safe casserole, alternate layers of sliced potatoes and sliced onion with prepared sauce.

Cover and microwave at medium-high power for 20-25 minutes or until potatoes are tender, gently stirring 3 times during cooking.

Let stand, covered, for 3 minutes before serving.
