Ingredients

• Cheddar cheese: melts for gooey goodness sharp cheddar gives bold flavor and higher quality blocks melt better than pre-shredded
• Eggs: bind everything together room temperature eggs blend in more smoothly
• Pork sausage: brings savory depth and a little fat brown it well for big flavor or swap with your favorite sausage or bacon
• Whole milk or heavy cream: adds creaminess and richness use whichever you have or try half-and-half
• Salt and black pepper: season every bite fresh ground pepper always gives more punch
• Garlic powder: adds a subtle background flavor use fresh or roasted if preferred

Step-by-Step Instructions

Preheat Your Oven and Prepare the Pan:

Set your oven to 375 degrees Fahrenheit. Spray a 9 by 13 inch glass or ceramic dish generously with nonstick spray so the casserole slides out easily and to make washing up simpler.

Brown the Sausage:

Place a large skillet on medium heat. Break up your sausage into small crumbles as it browns. Cook until all of it loses its pink color and the edges are a little crispy. Use a slotted spoon to move the sausage to a paper towel lined plate and let it drain.

Mix the Egg Base:

Crack eight eggs into a large mixing bowl. Pour in the whole milk or heavy cream. Add the salt black pepper and garlic powder. Whisk very well so the yolks are all broken up and the mixture is smooth and slightly frothy.

Layer the Casserole:

Spoon all the thawed hash browns into your baking dish and press them lightly into an even layer with your hands. Scatter the browned sausage over the top then sprinkle on the shredded cheddar cheese evenly. Pour the whisked egg mixture over everything slowly so it soaks into all the nooks and crannies.

Bake Until Golden:

Cover the dish snugly with foil and bake for forty minutes. Carefully remove the foil and return to the oven. Continue baking uncovered for twenty minutes more until the top is bubbling and lightly golden brown. Pull the casserole from the oven and wait five to ten minutes so it firms up before slicing.

Slice and Serve:

Cut the casserole into neat squares or rectangles. Lift out with a thin spatula and serve hot. I love mine with a drizzle of hot sauce or a big spoonful of salsa on top for a kick.

Hashbrowns are my ultimate comfort ingredient the sizzle and smell remind me of Saturday mornings in my childhood kitchen and now my own family begs for this casserole at every holiday brunch.

Storage Tips

Refrigerate leftovers tightly wrapped or in an airtight container for up to four days. To reheat cover with foil and warm in a 350 degree oven for about twenty minutes until heated through. You can also freeze slices tightly wrapped and pop one in the microwave or oven right from the freezer for a quick breakfast.

Ingredient Substitutions

This casserole is so flexible. Swap the pork sausage for turkey sausage or for a vegetarian meal sautéed mushrooms and bell peppers work perfectly. You can mix and match cheeses using sharp cheddar Monterey Jack even pepper jack for spice. If you are out of frozen hashbrowns use freshly grated potato just remember to squeeze out extra liquid before using so the casserole is never soggy.

Serving Suggestions

Serve slices alongside a crisp green salad for a balanced brunch. Top with chopped chives or green onions and a scoop of fresh salsa for color and brightness. Leftovers can be tucked into a tortilla for a breakfast burrito or layered on toast for a satisfying open face sandwich.
