Pour the Egg Mixture

Note
For a richer flavor, consider using a variety of sausages, such as spicy Italian or smoky chorizo. Feel free to mix in sautéed onions, bell peppers, or mushrooms for added texture and taste. To ensure the eggs set properly, whisk them thoroughly with milk or cream to create a smooth custard before combining with the other ingredients. If you'd like a cheesy crust, sprinkle shredded sharp cheddar or Gruyère over the top before baking. For a lighter version, substitute turkey sausage and use egg whites in place of some whole eggs. This casserole can be assembled the night before and baked fresh in the morning, making it perfect for a stress-free brunch. Finally, let the casserole rest for a few minutes after baking to allow it to firm up for easier slicing.
