How to Make Creamy Potato Gratin: Better Than Takeout
- Prepare the potatoes: Preheat your oven to 375°F (190°C). Peel the potatoes and slice them thinly using a mandoline slicer or sharp knife. You should have about 2 lbs (900g) of sliced potatoes.
- Make the cheese sauce: In a medium saucepan, heat the heavy cream, minced garlic, salt, and pepper over medium heat until hot but not boiling. Remove from heat and stir in the grated Gruyere cheese until melted and smooth.
- Assemble the gratin: Grease a 9×13-inch (23×33-cm) baking dish with butter. Arrange a layer of potato slices on the bottom, followed by a third of the cheese sauce. Repeat with two more layers of potatoes and cheese sauce, ending with a layer of potatoes.
- Bake the gratin: Cover the baking dish with aluminum foil and bake for 45 minutes. Remove the foil and bake for an additional 15-20 minutes, or until the potatoes are tender and the top is golden and bubbly.
- Serve: Let the gratin rest for 10 minutes before serving. Garnish with fresh thyme leaves and serve warm.
