Ingredients in Ham Tater Tot Breakfast Casserole

Frozen tater tots

Diced ham

Cheddar cheese



Sour cream

Mustard powder

Salt & pepper

All of these ingredients are easy to find – especially if you’re using up leftover ham! If not, you could definitely use ham deli meat or a ham steak and just chop it up. In addition, if you’re not a fan of ham, you can definitely use bacon or sausage instead.
