Au Gratin Potatoes

I love au gratin potatoes, but with a lactose intolerance I can’t take the easy way out and buy the boxed version. Which I fully admit is a guilty pleasure, or rather, was. These au gratin potatoes are cheesy, saucy, and even though they’re an usually traditional boring dish, still has great flavor.

Some au gratin recipes have onions, sliced or diced or sautéed, but the Hubby isn’t a fan and for me it’s all about the potatoes anyways. If you (or the family) loves onions, I would dice, sauté, and add to the layers.

To reheat, preheat the oven to 350F and heat for 20 to 30 minutes.
