Black Olive Potato Gratin Recipe

Directions:

1. Preheat oven to 375°F Drain olives, pat dry and cut in half lengthwise.
2. In a 4-qt. saucepan combine cream, onion, thyme, basil, salt and pepper. Bring to a boil over medium-high heat. Reduce heat; simmer 3 minutes. Stir in 1/2 cup of the Parmesan cheese until melted. Add olives; continue to simmer 3 minutes, stirring frequently.
3. Peel potatoes and slice as thinly as possible. Add to cream mixture in saucepan; mix well so as to coat potatoes with cream sauce.
4. Layer potatoes and olives in an 8 or 9-inch baking dish. Spoon any remaining cream sauce from saucepan over potatoes. Sprinkle Gruyere cheese and remaining 1/4 cup Parmesan cheese evenly over top. Cover dish with foil and bake 50 minutes. Uncover and bake 25 to 30 minutes longer, until golden brown and bubbly. Let stand 15 minutes before serving so potatoes absorb excess liquid.
