The Realtor's Garlicky Potatoes Au Gratin

READY IN: 2hrs 15mins
Recipe by Realtor by day

This is one of my favorite recipes for potatoes au gratin. I make this is an enameled cast iron casserole so I can make the sauce and bake the potatoes all in the same pan. If you don't have one of those, just make the sauce, stir in the potatoes and then pour the mixture into a buttered 2 or 3 qt. casserole dish.

Ohhhhhhh, once I serve this to DH, he will be melting at my feet. Sounds like a recipe for blackmail to me. Brutally good. Made for PRMR.
