5 Ingredient Breakfast Casserole (with frozen hashbrowns)

Need an easy meal to feed the family? Our 5 ingredient breakfast casserole fits the bill.

The breakfast potato, in its many shapes and forms, is pretty essential in our kitchen.

Who doesn’t love a versatile root veggie that can fill hungry bellies on a dime?

I like to keep different types of potatoes stocked in my freezer as well as fresh potatoes in the pantry.

A healthy homemade breakfast

This might sound crazy, but we stopped buying convenience breakfast foods about a year ago.

No cereal, no prepackaged pastries, nada. We now stick to waffles that we make and freeze on the weekends; homemade oatmeal; yogurt parfaits; or a variety of eggs, skillet scrambles and casseroles.

Keeping breakfast homemade and simple has done several things for us. First, it helps to curb our sugar intake – and avoid the mid-morning sugar crash.

It also saves a lot of money. Yes, I have to be more intentional about planning out our breakfast for the week, but overall it’s been really worthwhile.

With dishes like this 5-ingredient breakfast casserole, you can even make your homemade breakfast the night before, if you choose.

There’s nothing better than simply popping breakfast into the oven in the morning and having a hot meal baking while everyone is starting their day.

How to make this easy 5-ingredient breakfast casserole

With 5 ingredients, you probably guessed this is a simple meal to assemble. And you’d be correct!

You only need: frozen southern-style hashbrowns (the diced kind); eggs, milk; ground pork or sausage; and shredded cheese.

Add some salt & pepper and you’ve got a delicious breakfast ready that’s nearly dump-and-go.

If you buy pre-shredded cheese and assemble this casserole the night before, it’s even less hassle. Although, I have to admit, I really like to shred my own cheese. 😉

Optional add-in ideas

If you have random onions and peppers that need to be cooked, you can easily dice and add them to this casserole.

Even finely chopped brocolli would be an excellent add-in. For even more flavor, you could also add some garlic or onion powder.

I buy eggs from local friends who raise chickens, and they definitely make our breakfast casseroles even more delicious!

The dark yolks are so nice and fluffy. If you have access to farm fresh eggs, this is a great way to utilize them.
