Potato Gratin with Caramelized Onion

If you are looking for something different to put on your dinner table, make my potato gratin. It doesn’t take that much time to put together, but is a great potato dish to enjoy. The thing about this gratin is that you can customize it to your liking by adding your own favorite types of cheese, potatoes, and herbs.

This potato gratin is a French dish that uses the gratin technique, from the Dauphiné region in southeast France. Gratin dauphinoise is made with thinly sliced raw potatoes, milk or cream, and layered with Gruyère or other types of cheese, then cooked in a buttered dish rubbed with garlic. The potatoes are peeled and sliced to the thickness of a coin, usually with a mandoline or a food processor with slicer attachment. The potatoes are then layered in a glass baking dish and cooked in an oven.

I have made this dish many times, each time a bit different. The first time I made this dish with just cream, Gruyère cheese, garlic, salt, and pepper. It seemed a bit plain to my husband and I. This year I added caramelized onion, parmesan cheese and hatch chiles to the potatoes. This combination of flavors was excellent. Who doesn’t like rich, creamy and buttery potato dish have on their dinner table?
