Breakfast Casserole (Hash Browns & Eggs)

A Breakfast Casserole with Hash Browns and Eggs is the ultimate make-ahead dish for busy mornings, weekend brunches, or holiday gatherings.

It’s easy, customizable, and satisfying enough to keep everyone full until lunch.

Unlike individual hash browns and eggs cooked on the stovetop, this casserole bakes everything together in one dish.

The result is a layered breakfast packed with flavor and texture — crispy on the edges, creamy in the middle, and topped with golden cheese.
