Gruyère Potato Gratin

Preheat oven to 400 degrees F. Grease shallow 2-quart gratin pan or ceramic baking dish with margarine. Set aside.

In 3-quart saucepan, combine half-and-half, salt, and ground red pepper; heat to boiling over medium-high heat. Add potatoes and cook 2 minutes or until half-and-half mixture thickens slightly, stirring occasionally.

Transfer half of potato mixture to prepared gratin pan; sprinkle evenly with 3/4 cup Gruyère. Top with remaining potato mixture and remaining 1/4 cup Gruyère.

Bake gratin 30 to 35 minutes or until potatoes are fork-tender and top is golden.
