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 warms up, grab a 9×13 inch baking dish and grease it lightly with cooking spray or butter to prevent sticking. This sets the stage for your delicious Hash Brown Egg Casserole and ensures a crispy bottom layer.
Step 2: Arrange the Hash Browns
Take the frozen hash brown patties and arrange them in a single, even layer at the bottom of the greased baking dish. Press them down gently with your hands to create a sturdy base, which will hold the casserole together and add that delightful crunch. This layering is key to achieving a great texture.
Step 3: Add Cheeses and Ham
Next, evenly sprinkle the shredded sharp cheddar and Monterey Jack cheeses over the hash brown layer. Then, evenly distribute the diced cooked ham and chopped scallions on top. This colorful layering not only adds flavor but also makes your Hash Brown Egg Casserole visually appealing, ready for the custard mixture.
Step 4: Prepare the Egg Mixture
In a large mixing bowl, whisk together the large eggs and whole milk until the mixture is smooth and frothy. Add in salt, ground dry mustard, and garlic powder, continuing to whisk until all ingredients are well combined. This creamy custard will bind all the layers of your casserole, providing richness and flavor.
Step 5: Combine Layers and Bake
Pour the egg mixture evenly over the layered hash browns, cheese, ham, and scallions. Begin in the center and work your way outwards to ensure even distribution without displacing the ingredients below. Cover the dish tightly with aluminum foil and place it in the oven, baking for 25 minutes to set the base.
Step 6: Uncover and Finish Baking
After 25 minutes, carefully remove the foil to allow the casserole to brown. Bake for an additional 20 minutes or until the top is golden brown and a knife inserted into the center comes out clean. This will give you a beautifully baked Hash Brown Egg Casserole that is both fluffy and appetizing.
Step 7: Cool and Serve
Once baked to perfection, take the casserole out of the oven and let it cool for about 10 minutes before slicing. This resting period helps the flavors to meld and allows for cleaner, more manageable slices when serving. Optionally, garnish with extra chopped scallions for a fresh touch before indulging!

Hash Brown Egg Casserole Recipe FAQs
What type of hash browns should I use?
Absolutely! I recommend using frozen hash brown patties rather than fresh ones. Frozen has the perfect texture with just the right amount of crunch, whereas fresh potatoes can release moisture and make your casserole soggy.
How do I store leftover Hash Brown Egg Casserole?
You can store any leftovers in an airtight container in the refrigerator for up to 4 days. This way, you can enjoy the delicious flavors without losing their delightful texture.
Can I freeze Hash Brown Egg Casserole?
Very! To freeze, cut the casserole into individual portions and wrap each one tightly with plastic wrap or foil. Place the wrapped portions in a freezer-safe airtight container for up to 3 months. When you’re ready to enjoy, thaw in the fridge overnight and reheat in the microwave or bake until warm.
What if my casserole comes out too soggy?
If your casserole ends up soggy, it might be due to excess moisture from the ingredients. To avoid this, ensure you press the hash brown patties firmly into the baking dish to create a solid base, and avoid using fresh ingredients with high water content. If you ever have sogginess, try drying out your veggies before adding them, or keep an eye on your bake time!
Is this casserole safe for those with dietary restrictions?
Absolutely! You can customize the ingredients to suit various dietary needs. For example, swap the ham for turkey sausage for a lighter option, choose lactose-free cheese, or omit scallions altogether if there’s an allergy. It’s versatile and adaptable to fit your loved ones’ preferences!
How long does it take to reheat frozen portions?
When reheating frozen portions, I recommend thawing them in the refrigerator overnight for the best results. If you’re in a hurry, simply microwave individual servings for 1-2 minutes or bake at 350°F (175°C) for 15-20 minutes until heated through. Enjoy your cozy breakfast!
