Preheat the oven to 400ºF and grease a 9×13-inch casserole dish. Arrange the sliced potatoes upright in rows, packing them snugly into the dish.

Step 2

In a large bowl, whisk together the cream, milk, garlic powder, onion powder, dried thyme, salt, pepper, and melted butter. Pour the mixture evenly over the potatoes. Sprinkle the shredded cheese on top, then add the fresh thyme leaves if using.

Step 3

Cover with greased foil and bake for 60 to 75 minutes, until the potatoes are mostly tender. Remove the foil and bake for another 10 to 15 minutes, until the top is golden brown and bubbly. Let cool slightly before serving.
