Preparing the Dish
- Preheat your oven to 375°F. Grease a 9x13-inch baking dish.
- Slice russet potatoes into 1/8-inch rounds for uniform thickness.
- Melt butter in a saucepan, stirring until bubbly, about 1–2 minutes.
- Whisk in flour, then slowly add milk and cream while whisking until thickened.
- Season sauce with garlic powder, salt, and pepper, then stir in cheeses until melted.
- Layer half of potato slices, then half the ham, followed by a third of the cheese sauce.
- Repeat layering with remaining ingredients, ending with cheese on top.
- Cover with foil and bake for 30 minutes, then uncover and bake for an additional 15 minutes.
- Let rest for 10 minutes before slicing and serve warm with garnish.

Notes
Letting the casserole rest allows the sauce to thicken and flavors to meld beautifully.
