Step‑by‑Step Instructions for Hash Brown Egg Casserole
Step 1: Preheat Oven
Begin by preheating your oven to 350°F (175°C). While the oven heats, grab a 9×13 inch baking dish and generously grease it with butter or non-stick spray. This will prevent any sticking and help achieve that crispy texture on the bottom of your Hash Brown Egg Casserole.
Step 2: Layer Hash Browns
Take your frozen hash brown patties and arrange them evenly in the prepared baking dish. Make sure they cover the entire bottom surface and press them down firmly to create a solid base. This step is crucial for preventing any gaps in your casserole, ensuring a cohesive and delightful texture when baked.
Step 3: Add Fillings
Sprinkle the shredded sharp cheddar cheese and Monterey Jack cheese over the layer of hash browns. Next, add the diced cooked ham and chopped scallions uniformly across the top. This layering of ingredients will contribute to the rich flavors and textures that make this Hash Brown Egg Casserole a beloved dish for brunch.
Step 4: Prepare Custard
In a large mixing bowl, crack the large eggs and beat them well. Then, pour in the whole milk, and season with salt, dry mustard (if using), and garlic powder. Whisk everything together until the mixture is smooth and uniform. This custard will bind the casserole together and provide that soft, creamy texture once baked.
Step 5: Combine
Carefully pour the whisked egg mixture over the layered ingredients in the baking dish. To ensure even distribution and avoid disrupting the layers, you can pour the mixture slowly over the back of a spoon. This technique helps to blend the flavors without losing the beautiful structure you’ve created.
Step 6: Bake Covered
Cover your baking dish tightly with aluminum foil and place it in the preheated oven. Bake for 25 minutes, allowing the ingredients to set and meld together. Keeping it covered at this stage helps steam the casserole, ensuring a fluffy result.
Step 7: Bake Uncovered
After the initial baking time, carefully remove the foil and continue baking for an additional 20 minutes. Keep an eye on it; it should be golden and firm to the touch. You can check if it’s ready by inserting a knife; it should come out clean when the Hash Brown Egg Casserole is done.
Step 8: Cool & Serve
Once baked, take the casserole out of the oven and let it cool for 5-10 minutes before slicing. This resting time allows the casserole to firm up, making it easier to cut cleanly into portions. Serve warm and enjoy the delightful flavors of this comforting Hash Brown Egg Casserole with family and friends.
