I make this as a side dish. You can also add about a cup of cubed cooked ham to make this a main dish.

Oh, how we loved these rich and creamy au gratin potatoes. The cheddar cheese melts and combines with the heavy cream to form a thick and creamy sauce. Fresh onion gives a punch of flavor to the potatoes. Romano and cheddar cheese are sprinkled on top. Romano cheese is savory and is a nice touch. The hardest part of this side dish is peeling and slicing the potatoes. After that, it only takes a few minutes to prepare. This is the perfect potato side dish for when you want to indulge during the holidays.
