1-Preparation: Start by gathering all your ingredients and preheating your oven to 350 degrees Fahrenheit. Lightly spray a 9×13-inch pan with cooking spray to prevent sticking. Having everything ready before you begin makes the process seamless.

2-Cooking the Sausage: In a large skillet, cook the 2 pounds of hot breakfast sausage over medium heat until it’s no longer pink. Break up the sausage into crumbles as it cooks. Once fully cooked, drain the fat and set the sausage aside. This step is crucial as it removes excess grease and ensures your casserole isn’t overly oily.

3-Preparing the Hash Browns: Add the frozen shredded hash browns to the same skillet used for the sausage. Cook them over medium heat until they’re lightly browned. You may need to add a little oil to prevent sticking if the sausage didn’t leave enough fat in the pan. Browning the hash browns first improves their texture in the final dish, though this step is optional if you’re short on time.

4-Assembling the Casserole: Begin assembling your casserole by spreading the cooked hash browns evenly in the bottom of the prepared baking dish. This creates the sturdy base layer. Sprinkle the cooked sausage evenly over the hash browns, followed by the shredded cheddar cheese. These layers ensure that every bite contains all the delicious components.

5-Mixing the Egg Mixture: In a large bowl, whisk together 8 eggs, 2 cups of milk, 1 teaspoon salt, 1/2 teaspoon pepper, 1/4 teaspoon garlic powder, and 1/4 teaspoon onion powder until well combined. This mixture will bind all the ingredients together and create the creamy, custard-like texture that makes this casserole so satisfying.

6-Final Assembly and Baking: Pour the egg mixture evenly over the layers in the baking dish. At this point, you can cover the dish and refrigerate it if you’re planning to bake it later, which is perfect for meal prep or make-ahead breakfasts.

When ready to bake, place the uncovered dish in the preheated oven and bake for 35 to 40 minutes, or until the casserole is set and the top is golden brown. The center should be firm to the touch, and a knife inserted near the middle should come out clean.

7-Resting and Serving: Allow the casserole to rest for about 10 minutes before slicing and serving. This resting time helps the dish set, making it easier to cut into clean portions. Serve while still warm for the best flavor and texture.
