My mom always made fantastic au gratin potatoes when I was a child. Today I had a bunch of leftover potatoes from the local farmers market and I decided to test making au gratin with red potatoes using the colby and monterey jack shredded cheese mix in the fridge. I decided that this recipe for aug gratin potatoes would make a great side dish to the steaks my husband had ready for the grill.
