Ingredients

2 tablespoons olive oil
1 large yellow onion, thinly sliced
2 cups heavy whipping cream
4 cloves garlic, crushed
3/4 teaspoon kosher salt
1/2 teaspoon ground pepper
2 sprigs fresh thyme, plus 1 teaspoon chopped fresh thyme leaves for topping
2 1/2 lb Yukon Gold potatoes, peeled and thinly sliced
1 1/4 cups shredded Gruyère cheese (5 oz)

Steps

1

Heat oven to 325°F. Spray 2 1/2-quart oval casserole with cooking spray.
2

In 12-inch skillet, heat oil over medium heat. Add onion; cook 18 to 22 minutes, stirring frequently, until very soft and caramelized.
3

In 2-quart saucepan, heat whipping cream, garlic, salt, pepper and thyme sprigs to simmering over medium-high heat. Reduce heat; cover and simmer 10 minutes, stirring occasionally. Uncover and simmer 5 minutes longer, stirring occasionally. Set aside.
4

Layer one-fourth of the sliced potatoes in bottom of casserole. Top with one-third of the caramelized onions and 1/4 cup of the shredded cheese. Repeat layers two more times. Top with remaining potatoes. Strain cream mixture, and pour evenly over potatoes. Sprinkle remaining 1/2 cup cheese on top.
5

Bake uncovered 1 hour to 1 hour 10 minutes or until potatoes are tender and mixture is bubbling and browned on top. Cool 10 minutes. Sprinkle with 1 teaspoon chopped fresh thyme leaves before serving.
