How to Make Hash Brown Egg Casserole
Step 1: Preheat the Oven
Preheat your oven to 350 degrees F. Grease a 9×13 baking dish to prevent sticking when serving.
Step 2: Arrange Hash Browns
Arrange the frozen hash brown patties in the greased baking dish in a single layer. This forms the base of your casserole.

Sprinkle both cheeses, diced ham, and scallions evenly over the top of the hash browns. Ensure everything is distributed evenly for consistent flavor in every bite.

In a large mixing bowl, whisk together the eggs, whole milk, salt, dry ground mustard (if using), and garlic powder until well combined.
Step 5: Combine Ingredients
Pour the egg mixture evenly over the ham and cheese layer in the baking dish. This will bind all ingredients together as it cooks.
Step 6: Bake It Up!
Cover your casserole with foil and bake for 25 minutes. After that time, remove the foil and continue baking for an additional 20 minutes or until edges are golden brown and a knife inserted in the center comes out clean.
Step 7: Cool and Serve
Once baked, allow your Hash Brown Egg Casserole to cool for about 5-10 minutes. Cut into portions and serve warm. Enjoy!

Overmixing the egg mixture: Mixing too much can create a rubbery texture. Whisk just until combined for the best results.
Skipping the resting time: Cutting into the casserole immediately can cause it to fall apart. Allow it to cool for 5-10 minutes before serving.
Not adjusting for leftovers: If you use different types of meat or cheese, adjust the cooking time as necessary. Thicker layers may need longer baking.
Using expired ingredients: Always check that your eggs and dairy are fresh. This will ensure the best flavor and safety in your dish.
