Hashbrowns: You’ll need 3 cups of grated potatoes. You can grate your own peeled, Golden potatoes or use frozen hashbrowns, thawed and squeezed of any moisture.

How to Make a Cheesy Hashbrown Casserole

Step 1: Preheat the oven to 450 F and grease the baking dish. If you’ve grated your own potatoes, rinse them under cold water and pat them dry with paper towels.

Step 2: Place the hashbrowns into the bottom of the prepared baking dish and press it down into an even layer. Season with salt & pepper to taste and add 1 cup of the cheese overtop. Bake it for 15 minutes until the top is golden.

Step 3: In the bowl of a stand mixer, whisk the cream cheese until it’s smooth for about 3-5 minutes. Add one egg at a time, while continuously whisking until the eggs are all combined with the cream cheese. Season with black pepper.

Step 4: Meanwhile, sauté the ham and green onion in a skillet over medium heat for about 2-3 minutes, stirring occasionally. Sprinkle this mixture into the egg mixture.

Step 5: Once the potato hashbrown crust is done baking, pour the egg mixture overtop. Bake it for 10 minutes until the middle of the pie is set.

Sauté extra veggies with your ham and green onions. Bell peppers, mushrooms, zucchini, broccoli, and cauliflower would all make a yummy addition.
If you prefer a thinner layer of eggs, use just 6 eggs instead of 8.
You can also substitute hashbrown patties, potato cubes, or tater tots for the hashbrowns.

FAQs

How long does it take to bake a breakfast casserole?

If you’re baking it at 450 degrees F like I do, then you won’t need more than 10 minutes. You want to bake it until the top is golden and the egg mixture is set. Overcooking it could lead to a dry casserole and rubbery eggs!

The lower your temperature, the more time it’ll need in the oven. You know your oven best, just keep an eye on it.

How to store leftover Cheesy Hashbrown Casserole?

Keep any leftovers in an airtight container for up to 4 days in the fridge. Have a quick and easy breakfast, lunch, or snack to enjoy at home or at work throughout the week!

Can you freeze breakfast casserole?

Definitely! Once you’ve cut them into pieces and they’re completely cooled, wrap them in plastic wrap and transfer them to a freezer bag. Keep them frozen for up to 2 months. Thaw them in the fridge overnight.

How to reheat leftovers?

To reheat this dish, simply place it in the skillet, add a little amount of water, and cook on medium heat until it's hot.
If you have just one piece to heat up, you can easily just pop it in the microwave.
