- Add Greens: Stir in some baby kale, chopped fresh spinach, or arugula for extra color and nutrition.
How to Make the Wake Up Casserole
Step 1: Prep the Hashbrown Base
Preheat your oven to 375°F. Grab your favorite baking dish and give it a generous greasing—it really helps with easy serving later. Mix the frozen shredded hashbrowns with the melted butter, making sure every strand gets coated, then press the mixture evenly across the bottom of the dish.
Step 2: Sauté the Sausage and Aromatics
Set a skillet over medium-high heat and cook your breakfast sausage, breaking it up with a spoon as it browns. Add the chopped onion right into the pan to soften and caramelize alongside the sausage. Once everything’s nicely golden and fragrant, stir in the minced garlic for a quick 30-second sizzle (just to wake it up).
Step 3: Make the Egg Mixture
In a large bowl, whisk together the eggs, cottage cheese, shredded cheddar, and a good pinch of salt and pepper. Fold in the sausage mixture so everything’s well combined and evenly distributed—this keeps every bite loaded with flavor.
Step 4: Assemble and Bake
Pour your egg mixture right over the hashbrown base, spreading it out evenly. Slide the casserole into the preheated oven and bake for about 1 hour, or until set in the middle and lightly golden on top. You’ll know it’s ready when it doesn’t jiggle in the center.
Step 5: Garnish and Serve
Once baked, sprinkle the casserole with freshly chopped chives for a bright pop of color and fresh flavor. Let it sit for a few minutes before slicing to help everything set—then serve up hearty squares and dig in!
Pro Tips for Making the Recipe
- Press the Hashbrowns: Don’t just toss them in—use your hands or a spatula to really press them down. This helps create a crispier bottom layer.
- Use Quality Sausage: The sausage flavor really comes through, so pick one you love, or try a homemade blend for extra personality.
- Grate Cheese Fresh: Pre-shredded cheese works, but grating your own creates a creamier texture and better melt.
- Watch the Bake Time: All ovens differ, so start checking for doneness at 50 minutes—look for a puffed, golden top and a set center.
- Let It Rest: Allowing the casserole to cool for at least 10 minutes makes slicing much easier and keeps the servings tidy.
How to Serve
Wake Up Casserole shines all on its own, but it also plays nicely as the centerpiece for a bigger breakfast spread.
Classic Breakfast Plate
Serve piping hot with a side of fresh fruit, a green salad, or crispy bacon if you like a meaty double-punch. A dollop of sour cream or salsa on the side adds a fresh kick.
Brunch Buffet
Slice into smaller squares for a brunch buffet with muffins, pastries, and a pitcher of orange juice or mimosas. The casserole holds its shape and stays tasty even at room temperature.
Wrap It Up
Stuff a warm tortilla with a square of casserole and a little hot sauce for a speedy breakfast burrito—perfect for a grab-and-go meal.
Make Ahead and Storage
Storing Leftovers
Store leftovers in an airtight container in the refrigerator for up to four days. The casserole reheats beautifully and keeps its texture, making mornings a breeze.
Freezing
This breakfast beauty freezes well! Cool the casserole completely, cut into portions, and wrap each piece tightly or use freezer containers. Freeze for up to three months for a make-ahead breakfast that’s ready whenever you are.
Reheating
For single servings, use the microwave—just a minute or two will do. If reheating a larger portion, cover with foil and bake in a 350°F oven until warmed through. Add an extra sprinkle of cheese before reheating for extra appeal.
FAQs
-
Can I make this casserole the night before?
Absolutely. Assemble everything up to the baking step, cover tightly with foil, and refrigerate overnight. In the morning, simply bake as directed—add a couple extra minutes since it will be cold going into the oven.
-
Do I need to thaw the hashbrowns first?
There’s no need! Just mix them with melted butter straight from the freezer. If they are especially clumped together, let them stand at room temperature for a few minutes first—this makes them easier to spread as a base.
-
Can I use another type of breakfast meat?
Definitely. Breakfast sausage brings classic flavor, but feel free to swap in bacon, ham, or even a vegetarian sausage substitute. Just cook and crumble your choice before mixing in.
-
What can I substitute for cottage cheese?
Not a cottage cheese fan? Ricotta cheese or even sour cream will deliver that desired creaminess and moisture. Keep in mind, cottage cheese bakes up light and fluffy, so substitutes may make the casserole a little denser.

Ingredients
Potato Base
- 3 cups frozen shredded hashbrowns
- 1/4 cup melted unsalted butter
Meat & Aromatics
- 1 lb bulk breakfast sausage
- 1/2 medium onion, chopped
- 2 tsp minced garlic
Egg & Cheese Mixture
- 8 large eggs
- 16 oz cottage cheese
- 2 cups shredded cheddar cheese
- Salt and pepper, to taste
Garnish
- Chopped chives
Instructions
- Preheat the Oven – Set your oven to 375°F (190°C) to ensure it’s fully preheated by the time you’re ready to bake the casserole.
- Prepare Hashbrown Base – In a large mixing bowl, combine the frozen shredded hashbrowns with the melted unsalted butter. Mix until all the potatoes are lightly coated. Spread the mixture evenly in the bottom of a well-greased baking dish, pressing it down gently to form a solid base.
- Cook Sausage and Aromatics – Heat a skillet over medium-high heat. Add the breakfast sausage and chopped onion. Sauté until the sausage is browned and cooked through, and the onions are soft and translucent. Add the minced garlic and continue to cook for an additional 30 seconds, stirring frequently to prevent burning.
- Combine Remaining Ingredients – In a large bowl, whisk together the eggs, cottage cheese, and shredded cheddar cheese. Add the cooked sausage mixture and season generously with salt and pepper. Stir until all components are well blended.
- Assemble the Casserole – Pour the egg and sausage mixture evenly over the prepared hashbrowns in the baking dish, spreading it out with a spatula as needed so it covers the potatoes completely.
- Bake – Place the assembled casserole into the preheated oven and bake for 1 hour, or until the top is golden and the egg mixture is fully set in the center (a knife inserted should come out clean).
- Garnish and Serve – Remove the casserole from the oven and let it rest for a few minutes. Sprinkle freshly chopped chives over the top before cutting and serving warm.
