This hearty breakfast casserole with hash browns has been my family's cherished recipe passed down through generations. The combination of crispy potatoes, savory sausage, and melty cheese creates the ultimate morning comfort food that will satisfy even the pickiest eaters while keeping your kitchen filled with irresistible aromas.
I first made this casserole when hosting my in laws for Christmas morning. The ability to prepare it the night before saved my sanity and now it has become our non negotiable holiday breakfast tradition that everyone requests by name.
Ingredients
- Frozen hash browns: 2 pounds thawed completely for even cooking and to prevent excess moisture
- Pork sausage: 1 pound preferably maple flavored for that sweet savory contrast that makes this dish special
- Small onion: finely diced adds a subtle flavor foundation without overwhelming the dish
- Large eggs: 5 creates the perfect custardy texture that binds everything together
- Milk: 1/2 cup helps create that fluffy texture throughout the casserole
- Onion powder: 1/2 teaspoon provides uniform flavor without the texture of additional onions
- Garlic powder: 1/8 teaspoon adds depth without overpowering the breakfast flavors
- Salt and pepper: to taste adjusting based on the saltiness of your sausage and cheese
- Shredded cheddar: 12 ounces sharp varieties work best for maximum flavor impact
Step-by-Step Instructions
- Preparation:
- Preheat your oven to a moderate 350°F and thoroughly grease an 8 inch square baking dish. Spread the thawed hash browns in an even layer making sure to press lightly to create a solid base. Taking time here prevents gaps and ensures even cooking throughout.
- Cooking the Sausage:
- In a large skillet over medium heat brown the sausage and onion together breaking the sausage into small crumbles as it cooks. This should take about 10 minutes until the sausage is no longer pink and the onions have softened and become translucent. Drain off excess grease thoroughly to prevent a soggy casserole.
- Creating the Egg Mixture:
- In a large bowl whisk together eggs milk onion powder garlic powder salt and pepper until fully incorporated and slightly frothy. The whisking incorporates air which helps create a lighter texture in the final dish. Pour this mixture evenly over the hash browns ensuring complete coverage.
- Layering the Casserole:
- Sprinkle half the cheddar cheese over the egg soaked potatoes distributing it evenly to ensure cheese in every bite. Next spread the cooked sausage and onion mixture on top followed by the remaining cheese creating distinct layers of flavor that will meld during baking.
- Baking to Perfection:
- Cover the baking dish tightly with aluminum foil to trap moisture and heat which helps cook the casserole evenly. Bake covered for 1 hour then remove the foil and continue baking for approximately 10 more minutes until the cheese develops a golden crust and a knife inserted in the center comes out clean without runny eggs.
- Resting Before Serving:
- Allow the casserole to rest for at least 5 minutes before cutting. This crucial step allows the eggs to fully set and makes serving much neater with defined squares that hold their shape on the plate.

The maple flavored sausage is truly the secret ingredient that makes this recipe special. My grandmother always insisted on this particular variety claiming it added the perfect hint of sweetness against the savory eggs and potatoes. Now whenever I make this dish the distinctive aroma instantly transports me back to childhood holiday mornings.
