Potatoes Au Gratin with Bacon and Leeks
If you’re looking for comfort food, Potatoes Au Gratin is it. My late father in law made a version of these potatoes at every holiday dinner as far back as I can remember. It is one of my kids’ favorite recipes, and there are seldom any leftovers, no matter what else is on the menu. Because I am always playing around with recipes, I’ve updated them to use two kind of cheeses that complement each other and added a topping of delicious bacon and sautéed leeks.
This side dish casserole recipe looks more complex than it actually is. You are going to love the flavoring that the horseradish and Dijon mustard gives the sauce. The key though is using a wire mesh strainer to strain the horseradish from the light cream and chicken broth mixture. Afterwards you’ll discard the strained horseradish. By mixing it with the light cream and chicken broth, it gives it a nice flavor without being too strong. If you use a strainer with bigger holes, the horseradish flavor can be a bit overpowering.
