Preheat the oven to 375°F (190°C) and lightly grease a 9x13-inch baking dish with olive oil.
Peel the potatoes and slice them into thin, even rounds (about 1/8-inch thick). Use a mandoline slicer for uniform slices if available.
In a medium saucepan over medium heat, melt the butter. Add the minced garlic and thyme, cooking for 1-2 minutes until fragrant.
Slowly pour in the heavy cream, stirring to combine. Reduce the heat to low and let the mixture warm through without boiling.
Add salt, black pepper, and grated nutmeg to the cream mixture. Stir well and remove from heat.
Arrange one-third of the potato slices in an overlapping layer at the bottom of the prepared baking dish.
Pour one-third of the cream mixture evenly over the potatoes. Sprinkle one-third of the shredded cheddar and Parmesan cheese on top.
Repeat the layers two more times: potatoes, cream mixture, and cheeses. Make sure the top layer is fully covered with cheese for a golden crust.
Cover the baking dish tightly with aluminum foil and bake in the preheated oven for 40 minutes.
Remove the foil and continue baking for another 20 minutes, or until the potatoes are tender and the top is bubbling and golden brown.
Let the dish rest for 10 minutes before serving. Garnish with freshly chopped chives for a pop of color and flavor.
Serve warm and enjoy Potatoes McCallum as a hearty side dish or main course.
