Adaptable: While we always make socially viral recipes as is, this dish can easily be adapted to include bacon, veggies, or even change out the sausage to turkey sausage. Great veggies to include are white onions and green pepper.

Ingredients

For this recipe, you’ll need ground breakfast sausage—breakfast sausage is ideal, but you can also substitute turkey sausage, ground beef, or hot sausage if you prefer. You’ll also need all-purpose flour, milk, kosher salt, and black pepper for seasoning. The recipe calls for frozen diced hash brown potatoes, often labeled as southern-style, which are simply diced potatoes.

For the biscuits, I used Pillsbury Grands southern homestyle big flaky biscuits, but any refrigerated biscuits will work—just quarter them before adding. Shredded cheddar cheese is my go-to, but Colby Jack or Monterey Jack are great options too. And don’t forget the eggs, which should be beaten before adding.

How to make Sunday Breakfast Casserole

1. Add breakfast sausage to a large skillet and heat over medium-high heat until browned. Drain excess grease from brown sausage if necessary.
2. Add flour and mix well with the ground sausage. Stir in milk and season generously with salt and pepper.
3. Heat mixture over medium-high heat until mixture is thick and bubbly. Remove from heat and set aside.
4. In a separate skillet, cook hash brown potatoes according to package directions. Remove from heat once done.

1. Preheat the oven to 375 and grease a 9×13 baking pan with nonstick cooking spray. Spread cooked hashbrown potatoes into the bottom of the prepared baking dish.
2. Add quartered biscuit pieces on top of potatoes and 1-1/2 cups shredded cheddar cheese. Gently pour the beaten egg mixture on top, evenly distributing them throughout the pan.
3. Top with homemade gravy (including the cooked sausage), and top the entire casserole with the remaining 1/2 cup cheese. Bake breakfast casserole for 35-45 minutes or until bubbly and the center comes out clean when a knife is inserted.
4. Let the casserole dish stand for a few minutes before serving it hot.

Great Toppings

Breakfast casserole can be served with green onions or additional green bell pepper to add color to the dish. Some may want a side of hot sauce or sour cream.
