Plenty of cheesy goodness in Garlic Parmesan Au Gratin Potatoes with layers of thinly sliced potatoes, Parmesan cheese, and garlic. Serve it as a holiday side dish or alongside meat and potatoes for dinner.
Potatoes Au Gratin is easy to make and is one of my favorite side dishes. This cheesy potato casserole has layers of thin potatoes with a quick homemade cheese sauce and is baked until browned and bubbly! Pretty enough for guests, easy enough for any day of the week!
