Heat butter in a pot over medium heat. Add onions and sauté with a pinch of salt until translucent, about 5 minutes.

3 . Stage

Add flour and cook, stirring, just to take off that starchy, raw edge, about 2 minutes.

Pour in heavy cream and whisk to combine. Whisk in milk. Cook, stirring, over medium-high heat until it just starts to simmer and thicken up.

5 . Stage

Add 1 teaspoon salt, pepper, and cayenne. Grate in nutmeg.

Turn off heat. Stir in Worcestershire and fresh thyme leaves. Reserve until needed.

7 . Stage

Cover the bottom of a deep 10x15-inch casserole dish with about 25% of the reserved sauce.

8 . Stage

Add a layer of sliced potatoes, seasoning the tops with some of the remaining salt as desired; ladle over 1/3 of the sauce and sprinkle over 1/3 of the grated Cheddar cheese. Layer in ½ of the sliced ham.

9 . Stage

Place another layer of sliced potatoes on top and season with salt. Ladle over ½ of the remaining sauce; repeat layering with Cheddar cheese and ham.

10 . Stage
