There’s something comforting about a creamy, cheesy potato dish in the winter months. And while often thought of as casual fare, au gratin potatoes can go from nonchalant to elegant when special occasions call with a simple change of a few key ingredients. Here we’ve infused earthy thyme, rosemary and bay into a nutmeg-laced cream sauce. But that’s just the beginning.
Substitute your favorite combination of herbs and spices for a new flavor profile – give sage and thyme a try, or allspice with a pinch of cardamom. Drizzle a rich finishing oil over the top such as walnut, truffle or a peppery extra virgin olive oil. Or try a different combination of cheeses like smoked provolone and Asiago or a single cheese such as cheddar or Swiss.
