Step‑by‑Step Instructions for Hash Brown Egg Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While the oven heats, take a moment to grease a 9×13 baking dish with non-stick spray or butter. This important first step ensures your Hash Brown Egg Casserole won’t stick, allowing for easy serving later.
Step 2: Prepare the Hash Browns
Once your dish is ready, arrange the frozen hash brown patties evenly in a single layer at the bottom of the greased baking dish. Make sure they fit snugly together to create a stable base. This foundation will offer a delightful crunch, enhancing the overall texture of your casserole.
Step 3: Add the Cheese and Ham
Next, generously sprinkle sharp cheddar cheese and Monterey Jack cheese over the layer of hash browns. Follow this with the diced ham and chopped scallions, making sure everything is distributed evenly. This combination will create pockets of melty goodness and savory bites throughout the Hash Brown Egg Casserole.
Step 4: Whisk the Egg Mixture
In a medium-sized mixing bowl, crack the eggs and whisk them together with whole milk, salt, dry mustard, and garlic powder. Beat until the mixture is smooth and well combined. This egg mixture will serve as the binding agent, holding everything together and adding rich flavor to your casserole.
Step 5: Combine the Layers
Carefully pour the whisked egg mixture over the layered ingredients in the baking dish. Ensure the eggs coat all layers thoroughly, seeping into the hash browns, cheese, and meats. This step binds the casserole, making it moist and flavorful, ready to be cooked to perfection.
Step 6: Bake Covered
Cover the baking dish tightly with aluminum foil and place it in the preheated oven. Bake for 25 minutes at 350°F (175°C). This initial covered baking step allows the casserole to cook through evenly while keeping it moist.
Step 7: Bake Uncovered
After 25 minutes, carefully remove the foil and return the casserole to the oven. Bake for an additional 20 minutes or until the edges turn golden brown and a knife inserted in the center comes out clean. This final step will create a beautiful, golden crust atop your hearty Hash Brown Egg Casserole.
Step 8: Cool and Serve
Once baked to perfection, remove the casserole from the oven and let it cool for 5 to 10 minutes. This resting time allows the flavors to settle and makes cutting easier. Slice into portions, serve, and enjoy the warm, satisfying bite of your delicious Hash Brown Egg Casserole!
