Preheat your oven to 375°F (190°C) and butter a 9x13-inch baking dish using the unsalted butter.
Peel the potatoes, sweet potatoes, parsnips, and carrots, then slice them thinly (about 1/8-inch thick) using a sharp knife or mandoline. Arrange the slices into separate piles for easy layering.
In a medium saucepan over medium heat, combine the heavy cream, whole milk, grated garlic cloves, thyme leaves, nutmeg, salt, and black pepper. Heat until the mixture is warm but not boiling, stirring occasionally to infuse the flavors. Remove from heat.
Spread a thin layer of the cream mixture onto the bottom of the buttered baking dish. Begin layering the vegetables in an overlapping fashion; start with a layer of russet potatoes, followed by sweet potatoes, parsnips, and carrots. Repeat until all vegetables are used, making sure to alternate for a colorful presentation.
Pour the remaining cream mixture evenly over the layered vegetables, ensuring they are well-coated. Cover the dish tightly with aluminum foil and bake in the preheated oven for 50 minutes.
Remove the foil and sprinkle the shredded Gruyère cheese and grated Parmesan evenly over the top. Return the dish to the oven and bake uncovered for an additional 20-25 minutes, or until the cheese is golden brown and bubbling.
Let the gratin rest for 10 minutes before serving to allow the cream to set. Garnish with fresh parsley before serving.
