# How to Make:
01 - Preheat oven to 350°F. Grease a 9x13 inch baking dish with butter or nonstick spray.
02 - In a large saucepan, melt butter over medium heat. Add onion and cook until softened, about 3 to 4 minutes. Stir in garlic and cook for an additional minute.
03 - Sprinkle flour over the onion mixture and whisk constantly for 1 to 2 minutes. Gradually whisk in milk and cream, ensuring a smooth consistency.
04 - Simmer the sauce for 3 to 4 minutes until thickened. Season with salt, pepper, and nutmeg. Remove from heat and stir in half of the Gruyère and cheddar cheeses until melted.
05 - Arrange half the sliced potatoes in the prepared dish. Top with half the ham and pour over half the cheese sauce. Repeat layers with remaining potatoes, ham, and sauce.
06 - Sprinkle the remaining Gruyère, cheddar, and all Parmesan cheese evenly on top.
07 - Cover with foil and bake for 45 minutes. Remove foil and bake an additional 25 to 30 minutes until potatoes are tender and top is golden brown.
08 - Allow to rest for 10 minutes before serving. Garnish with chopped parsley if desired.
