Start your day with a hearty and delicious breakfast casserole that combines the savory flavors of sausage, hashbrowns, and cheddar cheese. This dish is perfect for feeding a crowd or meal prepping for the week. With its golden, cheesy top and satisfying layers, it's sure to become a family favorite.
If you don't typically keep breakfast sausage or frozen hashbrowns on hand, you might need to pick them up at the supermarket. Look for breakfast sausage in the refrigerated section, often near the bacon and other breakfast meats. Frozen hashbrowns can usually be found in the frozen foods aisle, near other potato products.
Ingredients For Sausage Hashbrown Breakfast Casserole
Breakfast sausage: Adds a savory, meaty flavor to the casserole.
Frozen hashbrowns: Provides a crispy, starchy base for the dish.
Shredded cheddar cheese: Melts beautifully to create a gooey, cheesy topping.

Technique Tip for Making This Breakfast Casserole
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, providing a consistent flavor in every bite. Additionally, when combining the hashbrowns, sausage, and cheese in the mixing bowl, use a folding motion to avoid breaking the hashbrowns too much, which helps maintain a desirable texture in the final dish.

How To Store / Freeze This Breakfast Casserole
Allow the casserole to cool completely before storing. This helps prevent condensation, which can make the dish soggy.
For short-term storage, transfer the casserole to an airtight container or cover the baking dish tightly with aluminum foil or plastic wrap. Store in the refrigerator for up to 3-4 days.
For longer storage, cut the casserole into individual portions. Wrap each portion tightly in plastic wrap and then place them in a freezer-safe bag or container. Label with the date and freeze for up to 2-3 months.
To reheat from the refrigerator, preheat your oven to 350°F (175°C). Place the casserole in an oven-safe dish and cover with aluminum foil. Heat for about 20-25 minutes or until warmed through.
To reheat from the freezer, it's best to thaw the casserole overnight in the refrigerator. Once thawed, follow the same reheating instructions as for refrigerated casserole.
For a quicker reheating option, you can use the microwave. Place a portion of the casserole on a microwave-safe plate and cover with a damp paper towel. Microwave on medium power for 2-3 minutes, checking and stirring halfway through, until heated evenly.
If you prefer a crispier texture, after microwaving, you can place the casserole under the broiler for a few minutes to achieve a golden-brown top.
Always ensure the casserole is heated to an internal temperature of 165°F (74°C) before serving to ensure food safety.
How To Reheat Leftovers
Oven Method: Preheat your oven to 350°F (175°C). Place the leftover sausage hashbrown breakfast casserole in an oven-safe dish. Cover it with aluminum foil to prevent it from drying out. Heat for about 20-25 minutes, or until it’s warmed through and the cheese is melted and bubbly.
Microwave Method: Place a portion of the casserole on a microwave-safe plate. Cover it with a microwave-safe lid or a damp paper towel to retain moisture. Heat on medium power for 2-3 minutes, checking halfway through to ensure even heating. If needed, continue heating in 30-second intervals until hot.
Stovetop Method: Heat a non-stick skillet over medium-low heat. Add a small amount of butter or olive oil to the pan. Place the casserole in the skillet and cover with a lid. Heat for about 5-7 minutes, flipping occasionally to ensure even warming. This method can help maintain a crispy texture on the hashbrowns.
Air Fryer Method: Preheat your air fryer to 350°F (175°C). Place the casserole in the air fryer basket, ensuring it’s in a single layer. Heat for 5-7 minutes, checking halfway through to ensure it’s warming evenly. This method can help achieve a crispy top layer.
Toaster Oven Method: Preheat your toaster oven to 350°F (175°C). Place the casserole on a toaster oven-safe tray. Cover with aluminum foil to prevent drying out. Heat for 15-20 minutes, or until it’s thoroughly warmed and the cheese is melted.
