Hash brown egg casserole reminds me of a weekend when I wanted to make a hearty breakfast that would feed everyone with minimal effort because I had family staying over. I layered crispy hash browns, savory sausage, fluffy eggs, and melted cheese into a baking dish, then baked it until golden and bubbly. The smell alone had everyone gathering in the kitchen before it was even done.

Since then, this dish has become a breakfast favorite because it’s filling, easy to prepare ahead, and perfect for serving a crowd. Each bite is cheesy, flavorful, and full of comforting textures.
