Gather your ingredients so that you have everything close at hand. Grease a 2-quart baking dish. Grate the Pepper Jack Cheese. Chop ham into small cubes.
Arrange hash browns evenly on the bottom of the dish. Sprinkle with cheese and ham.
In a small bowl, whisk together the large eggs, half and half cream, minced onion, dried chives, kosher salt and black pepper. Pour egg mixture over potatoes and ham. Cover with plastic wrap and refrigerate overnight.
Bake in a preheated 350 degree oven for 40-50 minutes until eggs are set. Let rest 10 minutes before serving. Serves 8-10
