Preheat your oven to 375°F (190°C). Grease a 9x13-inch baking dish with olive oil.
Peel the Yukon gold potatoes, parsnips, carrots, and turnip. Thinly slice all vegetables into rounds using a sharp knife or a mandoline. Set aside.
Cut the ham into small, bite-sized cubes. Grate the Gruyere cheese and divide it into two portions: 150 grams for the layers and 50 grams for the topping.
In a medium saucepan, heat the butter over medium-low heat. Mince the garlic and add it to the melted butter. Sauté for 1 minute until fragrant.
Add the heavy cream, milk, thyme, salt, pepper, and nutmeg into the saucepan. Cook the mixture over low heat, stirring frequently, until warm. Do not let it boil. Remove from heat.
Arrange a third of the sliced vegetables in an even layer in the prepared baking dish. Sprinkle a third of the ham and a third of the Gruyere (from the 150-gram portion) over the vegetables.
Repeat the layering process two more times: vegetables, ham, and cheese.
Pour the warm cream mixture evenly over the layered vegetables, ensuring it seeps through all the layers.
Cover the baking dish tightly with aluminum foil and bake in the preheated oven for 50 minutes.
Remove the foil, sprinkle the remaining 50 grams of Gruyere cheese evenly over the top, and return the dish to the oven. Bake uncovered for an additional 25 minutes, or until the top is golden brown and bubbly and the vegetables are tender.
Let the gratin rest for 10 minutes before serving. Garnish with fresh thyme leaves, if desired. Serve warm.
