1. Caramelize Onions

Melt butter in a large skillet and add the thinly sliced onions. Cook, stirring occasionally, until deeply golden brown.

3. Layer the Potatoes

Butter a 3 qt. baking dish and using a slotted spoon, layer the potatoes, onion, and gruyere. Top with the remaining cream.

4. Top with Cheese

Top the gratin with more gruyere cheese and bake at 375 F for 40 minutes, until the cheese is bubbly and potaotes are tender.
