Notes

Use a different potato. Tater Tots can be used instead of the hash brown patties, but you'll need to cook the casserole for an additional 5-10 minutes. You can also opt to shred your own potatoes or buy refrigerated hash browns, but they will require pre-cooking, which does add an extra step.
Swap out the ham. Use up any leftover holiday ham or purchase a ham steak and dice it up in minutes. You could also swap out the ham for cooked crumbled sausage or bacon, or a combination. For a vegetarian option, omit the meat and replace it with sautéed vegetables like onions, bell peppers, and mushrooms.
Try a different cheese. My family loves Monterey Jack and sharp cheddar, but you can swap these out for different cheeses. Pepper Jack would be delicious for some added heat.
