Step‑by‑Step Instructions for Hash Brown Egg Casserole

Step 1: Preheat and Prepare
Begin by preheating your oven to 375°F (190°C). While the oven heats, generously grease a 9×13 inch baking dish with cooking spray or butter to prevent sticking. This is an important step for achieving that lovely golden-brown crust on your Hash Brown Egg Casserole, ensuring every bite is delicious and perfectly cooked.

Step 2: Cook the Sausage
In a large skillet, heat over medium-high heat and add the ground breakfast sausage. Cook for about 6-8 minutes, breaking it apart with a spatula, until browned and cooked through. If using onions and peppers, add them to the skillet in the last 2-3 minutes of cooking, sautéing until softened. Drain any excess grease to keep your casserole from becoming too greasy.

Step 3: Layer the Hash Browns
Once the sausage mixture is ready, take your thawed shredded hash browns and layer them evenly in the greased baking dish, pressing them down firmly to create a solid base. This step is crucial for achieving the ideal texture, so ensure there are no gaps. You want a sturdy foundation for your comforting Hash Brown Egg Casserole.

Step 4: Add Sausage and Cheese
Next, sprinkle the cooked sausage mixture evenly over the layer of hash browns. Then, take half of your shredded cheese and scatter it over the sausage, ensuring even coverage. This combination of savory sausage and melty cheese will infuse every bite with rich flavor, setting the stage for a truly satisfying casserole.

Step 5: Whisk Together Egg Mixture
In a large mixing bowl, crack the 12 large eggs and add 1 cup of milk, 1 teaspoon of salt, 1/2 teaspoon of black pepper, and 1/2 teaspoon of garlic powder. Whisk these ingredients together until well combined and frothy, which should take about 1-2 minutes. This egg mixture is the heart of your Hash Brown Egg Casserole, providing that creamy texture we all love.

Step 6: Pour and Top
Carefully pour the egg mixture over the layered hash browns, sausage, and cheese in the baking dish, making sure to cover everything evenly. Once the egg mixture is distributed, top the casserole with the remaining cheese, sprinkling it generously on top. This crowns your Hash Brown Egg Casserole with a melty, golden finish.

Step 7: Bake to Perfection
Place the assembled casserole in the preheated oven and bake for 45-55 minutes, or until the center is set and a lovely golden-brown crust forms on top. To check for doneness, insert a knife into the center; it should come out clean. This visual cue indicates that your casserole is ready to emerge from the oven.

Step 8: Cool and Serve
Once baked, remove the casserole from the oven and let it rest for about 10 minutes before slicing. This resting time allows the layers to firm up, making it easier to cut into perfect squares. Serve your Hash Brown Egg Casserole warm, and enjoy the delicious transformation of simple ingredients into a comforting breakfast favorite.
