Nothing spells comfort food like cheesy, creamy, potatoes au gratin! In my home, we recently put a twist on this old family favorite by adding homemade chorizo and a creamy queso dip to the mix. YUM. It’s deliciously, mildly spicy and oh so indulgent. If your family enjoys the kick of chorizo and the perfect creaminess of homemade nacho cheese, they will love this Creamy Chorizo Potatoes Au Gratin casserole.
