This wake up casserole is the perfect dish to start your day with a hearty and satisfying meal. Combining the flavors of breakfast sausage, cheddar cheese, and hash browns, this casserole is easy to prepare and sure to please everyone at the table. Whether you're feeding a crowd or just looking for a delicious breakfast option, this recipe has got you covered.
Most of the ingredients in this recipe are common pantry staples, but you may need to pick up a few items at the supermarket. Make sure to get frozen hash browns and breakfast sausage. The hash browns should be thawed before use, and the sausage needs to be cooked and crumbled. If you don't have cheddar cheese on hand, any shredded cheese will work as a substitute.

Wake Up Casserole Ingredients
Eggs: Provides the base and structure for the casserole.
Milk: Adds creaminess and helps bind the ingredients together.
Breakfast sausage: Adds a savory and flavorful element to the dish.
Cheddar cheese: Melts into the casserole, adding richness and a cheesy flavor.
Frozen hash browns: Provides a hearty and filling base for the casserole.
Salt: Enhances the overall flavor of the dish.
Black pepper: Adds a touch of spice and depth to the flavor.
Technique Tip for This Recipe
When preparing the hash browns for this casserole, make sure they are thoroughly thawed and patted dry to remove any excess moisture. This will help prevent the casserole from becoming too watery and ensure a nice, crispy texture. Additionally, when whisking the eggs and milk together, make sure to whisk until the mixture is fully combined and slightly frothy. This will help incorporate air into the mixture, resulting in a lighter and fluffier casserole.
Suggested Side Dishes
Alternative Ingredients
eggs - Substitute with flax eggs: Mix 1 tablespoon of ground flaxseed with 3 tablespoons of water for each egg. Let it sit for a few minutes to thicken. This works well as a binder in casseroles.
milk - Substitute with unsweetened almond milk: It provides a similar consistency and is a good option for those who are lactose intolerant or prefer a dairy-free alternative.
cooked and crumbled breakfast sausage - Substitute with cooked and crumbled turkey sausage: Turkey sausage is a leaner option with less fat and calories, making it a healthier choice.
shredded cheddar cheese - Substitute with shredded mozzarella cheese: Mozzarella has a milder flavor and melts well, making it a good alternative for those who prefer a less sharp taste.
thawed frozen hash browns - Substitute with grated fresh potatoes: Freshly grated potatoes can be used in place of frozen hash browns. Just be sure to squeeze out excess moisture before using.
salt - Substitute with sea salt: Sea salt can be used in the same quantity and provides a slightly different mineral content and flavor.
black pepper - Substitute with white pepper: White pepper has a similar heat level but a slightly different flavor profile, which can add a unique twist to the dish.

How To Store or Freeze This Casserole
Allow the casserole to cool completely before storing. This prevents condensation from forming, 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.
If you plan to freeze the casserole, cut it into individual portions. This makes reheating easier and more efficient.
Wrap each portion tightly in plastic wrap, then place the wrapped portions in a freezer-safe bag or container. Label with the date to keep track of freshness.
The casserole can be frozen for up to 2-3 months. For best results, consume within this timeframe to maintain optimal flavor and texture.
To reheat from the refrigerator, preheat your oven to 350°F (175°C). Place the casserole in an oven-safe dish and cover with foil. Heat for about 20-25 minutes or until warmed through.
For reheating from frozen, it's best to thaw the casserole in the refrigerator overnight. Once thawed, follow the same reheating instructions as above.

For a quick microwave option, 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 and stirring halfway through, until hot.
