How to Make Sausage Hash Brown Breakfast Casserole Recipe
Step 1: Prepare the Oven and Pan
Preheat your oven to 350ºF so it’s ready when your casserole mixture is assembled. Lightly spray your 9×13-inch pan with cooking spray—this helps prevent sticking and makes cleanup easier later. Getting everything prepped upfront keeps the process smooth and stress-free.
Step 2: Cook the Sausage
In a large skillet over medium heat, cook the hot breakfast sausage until it’s no longer pink. This step is where the sausage releases its flavorful spices and fat. Once cooked, drain the fat thoroughly to avoid a greasy casserole. Set the sausage aside to cool slightly—this will make layering easier in the following steps.
Step 3: Brown the Hash Browns
Using the same skillet, add your frozen shredded hash browns. Cook them until they turn a light golden brown, stirring occasionally to prevent sticking. If your skillet is dry, add a little oil to help crisp the potatoes evenly. This step is key because it gives your casserole that wonderful crispy texture in every bite.
Step 4: Layer the Casserole
Spread the browned hash browns evenly in the bottom of your prepared pan. Next, sprinkle the cooked sausage evenly over the potatoes. Finally, top with the shredded cheddar cheese. These layers build the flavor and texture contrasts that make this casserole so irresistible.
Step 5: Mix and Pour the Egg Mixture
In a bowl, whisk together the eggs, salt, pepper, garlic powder, onion powder, and milk. Pour this custard mixture evenly over the layered hash browns, sausage, and cheese. The eggs soak into the layers below, binding everything into a luscious, cohesive breakfast that holds up well when sliced.
Step 6: Optional Refrigeration and Baking
You can cover the casserole and refrigerate it at this point if you want to bake it later—perfect for prepping the night before a big brunch. When ready, bake uncovered for 35 to 40 minutes, or until the egg custard is fully set and the top has a light golden hue. Let it cool for a few minutes before serving to allow those layers to settle beautifully.
How to Serve Sausage Hash Brown Breakfast Casserole Recipe

Garnishes
A sprinkle of freshly chopped green onions or parsley adds an inviting pop of color and freshness that contrasts beautifully with the casserole’s rich flavors. You can also add a dollop of sour cream or a drizzle of hot sauce for those who enjoy a bit of tang or heat with their breakfast.
Side Dishes
Pair your sausage hash brown breakfast casserole with a fresh fruit salad or a simple green salad to lighten the meal. Some crusty toast or warm biscuits work wonderfully for soaking up any leftover custard and cheese, making your breakfast feel even more indulgent.
Creative Ways to Present
For a fun brunch twist, serve the casserole in individual ramekins or muffin tins—this makes portion control effortless and adds a charming personal touch. You can also top each serving with an over-easy egg for extra decadence or some sliced avocado for creaminess and color.
Make Ahead and Storage
Storing Leftovers
Once cooled, cover the casserole tightly and store it in the refrigerator for up to four days. The flavors meld and deepen overnight, making leftovers even more delicious, and it’s easy to reheat as a quick breakfast or snack.
Freezing
This Sausage Hash Brown Breakfast Casserole Recipe freezes beautifully. For optimal results, assemble the casserole and freeze before baking. Thaw it overnight in the refrigerator, then bake as directed. You can also freeze cooked leftovers in airtight containers and reheat as needed without losing flavor or texture.
Reheating
Reheat individual portions in the microwave for about 1-2 minutes or warm a large portion in a 350ºF oven until heated through. You’ll want to cover it loosely with foil to keep it moist while allowing the cheese to stay melty and delicious.
