This cheesy hamburger potato casserole is made without condensed soup. Ground beef, sliced potatoes, and a homemade milk, broth, and Greek yogurt sauce bake under mozzarella and cheddar.
For a lighter version, try using ground turkey or chicken (cook to 165°F). Swap Russet potatoes for sweet potatoes for a sweeter flavor. Refrigerate leftovers within 2 hours and eat within 3 to 4 days; reheat to 165°F.
