Step‑by‑Step Instructions for Hash Brown Egg Casserole

Step 1: Preheat and Prepare
Begin by preheating your oven to 375°F (190°C), allowing it to reach the perfect baking temperature for your Hash Brown Egg Casserole. While the oven warms, grease a 9×13-inch baking dish generously with butter or cooking spray, ensuring easy removal after baking. Set the dish aside, ready for the delicious layers to come.

Step 2: Cook the Meat
In a skillet over medium heat, cook the breakfast sausage or bacon until browned and nicely crispy, which usually takes about 5-7 minutes. Stir occasionally to ensure even cooking. Once cooked, carefully drain any excess fat, then set the meat aside to cool slightly as it will add savory flavor to your casserole.

Step 3: Layer the Hash Browns
Spread the thawed hash browns evenly in the greased baking dish, creating a solid base for your casserole. Use the back of a spatula to press them down gently. This layer is crucial for achieving that comforting texture and crispy edge. Next, sprinkle the crumbled sausage or bacon evenly over the hash brown layer.

Step 4: Add Vegetables and Cheese
Now, sprinkle the diced onion and bell pepper across the meat layer, adding color and sweetness to the Hash Brown Egg Casserole. Follow this with 1½ cups of shredded cheddar cheese, which will melt beautifully as it bakes, providing that gooey, delicious texture we crave in a casserole.

Step 5: Whisk the Egg Mixture
In a large mixing bowl, whisk together the eggs, whole milk, garlic powder, salt, and black pepper until well combined. This egg mixture brings richness and moisture to your casserole. Once it’s thoroughly blended, pour it evenly over the layered ingredients in the baking dish, covering all the components nicely.

Step 6: Top and Bake
Sprinkle the remaining ½ cup of cheddar cheese over the top of your casserole for added flavor and a golden finish. Cover the dish with aluminum foil—this helps the casserole cook evenly. Bake in the preheated oven for 30 minutes, allowing the flavors to meld and the eggs to set.

Step 7: Finish Baking
After 30 minutes, remove the foil and return the casserole to the oven for an additional 15-20 minutes. Keep an eye out for a golden-brown top and a firm set in the center, confirming that your Hash Brown Egg Casserole is perfectly baked and ready to shine on your table.

Step 8: Cool and Serve
Once baked, let the casserole cool for about 5-10 minutes to make slicing easier. Optionally, garnish with chopped fresh parsley for a touch of color and freshness. Cut into squares, serve warm, and watch as your family enjoys this comforting and hearty dish, perfect for any meal of the day.
