This comforting dish combines savory breakfast sausage, crispy hashbrowns, and gooey cheddar cheese to create a breakfast that will satisfy the whole family. Perfect for a weekend brunch or a special occasion, this casserole is easy to prepare and sure to become a favorite.
If you don't typically keep breakfast sausage or frozen hashbrowns on hand, you'll need to pick these up at the supermarket.

Make sure to thaw the hashbrowns before using them in the recipe.

Ingredients For Sausage Hashbrown Breakfast Casserole
Breakfast sausage: Adds a savory and flavorful protein to the casserole.
Frozen hashbrowns: Provides a crispy and hearty base for the dish.
Shredded cheddar cheese: Melts into the casserole, adding a rich and creamy texture.
Milk: Helps to bind the ingredients together and adds moisture.
Eggs: Acts as a binding agent and adds richness to the casserole.
Salt: Enhances the overall flavor of the dish.

Technique Tip for This Recipe
When browning the sausage, make sure to break it up into small, even pieces to ensure it cooks thoroughly and evenly. This will help distribute the flavor throughout the casserole. Additionally, for a crispier texture, you can lightly sauté the hashbrowns in the same skillet after cooking the sausage, allowing them to absorb some of the sausage drippings before mixing them into the casserole.

How to Store / Freeze This Casserole
- Allow the casserole to cool completely before storing. This ensures that condensation doesn't form, which can make the hashbrowns soggy.
- For short-term storage, cover the baking dish tightly with aluminum foil or plastic wrap. Alternatively, transfer the casserole to an airtight container.
- Store in the refrigerator for up to 3-4 days. Reheat individual portions in the microwave or the entire dish in the oven at 350°F (175°C) until warmed through.
- For freezing, cut the cooled casserole into individual portions. Wrap each portion tightly in plastic wrap and then in aluminum foil to prevent freezer burn.
- Place the wrapped portions in a freezer-safe bag or container. Label with the date to keep track of freshness.
- Freeze for up to 2-3 months. To reheat, thaw overnight in the refrigerator and then warm in the oven at 350°F (175°C) until heated through.
- For a quicker option, reheat from frozen in the microwave, but note that this may affect the texture of the hashbrowns.
- If you prefer, you can also freeze the uncooked casserole. Assemble the dish as directed, but do not bake. Cover tightly with aluminum foil and freeze.
- When ready to bake, thaw overnight in the refrigerator and then bake as directed, adding an additional 10-15 minutes to the baking time to ensure it is heated through.
How to Reheat Leftovers
Preheat your oven to 350°F (175°C). Place the leftover sausage hashbrown breakfast casserole in an oven-safe dish. Cover with aluminum foil to prevent it from drying out. Bake for about 20-25 minutes, or until heated through.
For a quicker option, use the microwave. Place a portion of the casserole on a microwave-safe plate. Cover with a microwave-safe lid or another plate to retain moisture. Heat on medium power for 2-3 minutes, checking halfway through to ensure even heating.
If you prefer a crispy texture, reheat in a skillet. Heat a non-stick skillet over medium heat. Add a small amount of olive oil or butter. Place the casserole in the skillet and cook for 5-7 minutes, flipping occasionally, until heated through and crispy.
For an air fryer, preheat to 350°F (175°C). Place the casserole in the air fryer basket in a single layer. Cook for 5-7 minutes, shaking the basket halfway through to ensure even heating.
If you have a toaster oven, preheat to 350°F (175°C). Place the casserole on a baking sheet and cover with aluminum foil. Bake for 15-20 minutes, or until heated through. Remove the foil for the last 5 minutes to crisp up the top.
