Ingredients For This Breakfast Casserole With Hash Browns
- Shredded hash browns – fresh or frozen (see notes below for tips how to thaw)
- Eggs

- Precooked ham – diced
- Sour cream – or Greek yogurt
- Onion – chopped
- Evaporated milk – or half and half

How to thaw frozen Shredded hash browns
I prefer to let the frozen hash browns defrost on a baking sheet. It takes about 30-60 minutes total.
If you’re in a hurry, you can place the frozen hash browns on a baking sheet. Bake then bake them at 170º Fahrenheit for about 15 minutes to thaw them quickly.
Of course, you can always thaw frozen hash brown potatoes right in their bag overnight in the refrigerator. Put a plate or container underneath the package of shredded potatoes baking while defrosting in the fridge to keep them from making a mess.
Tip: Do not rinse hash browns (fresh or frozen)! The potatoes will soak up the water and it will make your casserole soggy.
How to Make the Easiest Breakfast Casserole
- Preheat oven to 375° Fahrenheit.
- In a large bowl, mix together hash brown potatoes, eggs, 1/2 of the cheese, ham, sour cream, onions, milk, melted butter, and seasonings.
- Pour hash brown casserole ingredients into the prepared casserole dish and top with remaining shredded cheese.
- Bake for 45-50 minutes, or until hot and bubbly and golden on top, and the edges of the breakfast casserole are puffy. Let cook for 10 minutes and serve!
