Easy Potatoes au Gratin – Just 5 Ingredients

Confession. This is the first time I have ever made homemade potatoes au gratin. WAY back when my husband and I first got married I made him the boxed version a few times, but they were never really that fantastic, so I stopped making them. The slicing of the potatoes and making the sauce and getting the cheese just right was always intimidating to me for some reason. So, I never made it. Until today. With the holidays coming and potatoes are always on the table, I figured it was the perfect time to perfect this cheesy, creamy side dish.

You can broil the dish for 1 minute or so at the end to get the cheese extra brown if you would like.
