Ingredients For Sausage Hash Brown Breakfast Casserole
Breakfast sausage: Adds a savory and slightly spicy flavor to the casserole.
Frozen hash browns: Provides a crispy and hearty base for the dish.
Shredded cheddar cheese: Melts beautifully and adds a rich, cheesy taste.
Eggs: Helps to bind the ingredients together and adds protein.
Milk: Creates a creamy texture and helps to blend the flavors.
Salt: Enhances the overall flavor of the dish.

Technique Tip for This Recipe
When cooking the sausage, make sure to break it up into small, even pieces as it browns. This ensures that the sausage is evenly distributed throughout the casserole, giving each bite a balanced flavor. Additionally, consider using a mix of cheddar cheese and another type of cheese, such as Monterey Jack or pepper jack, to add a layer of complexity to the dish. When whisking the eggs and milk, make sure they are fully combined and slightly frothy; this will help the casserole set more evenly and create a light, fluffy texture.
