Preheat your oven to 375°F (190°C). Grease a 9x13-inch baking dish with the unsalted butter and set it aside.
Peel and thinly slice the russet potatoes (about 1/8-inch thickness) using a knife or mandoline. Keep the slices in a bowl of cold water to prevent them from browning.
In a medium saucepan over medium heat, combine the heavy cream, minced garlic, salt, black pepper, and fresh thyme. Heat until the mixture is warm, but do not let it boil. Remove from heat and set aside.
Drain the potato slices and pat them dry with a clean kitchen towel or paper towel.
Layer one-third of the potato slices evenly in the bottom of the prepared baking dish. Sprinkle one-third of the cooked ham and one-third of the shredded Gruyere cheese over the potato layer. Pour about one-third of the warm cream mixture evenly over the top.
Repeat the layering process two more times, ending with a layer of Gruyere cheese on top.
Cover the baking dish with aluminum foil and bake in the preheated oven for 40 minutes.
Remove the foil and continue baking for an additional 20 minutes, or until the top is golden and bubbly and the potatoes are tender when pierced with a fork.
Let the gratin cool for 10 minutes before serving. Garnish with additional fresh thyme if desired.
