Hash Brown Breakfast Casserole

In this post I’ll be sharing a delicious hash brown breakfast casserole recipe that you and your family will love.

Are you searching for hash brown breakfast ideas? Besides throwing the hash brown potatoes into a hot cast iron skillet or on a hot griddle, I mean. Well, my friend, I’ve got a delicious sausage and hash brown breakfast casserole that will make everyone happy.

Y’all, I love a good breakfast casserole! I love breakfast! In fact, breakfast might just be my most favorite meal of the day. Okay, admittedly, I love all meals, but breakfast has a really special place in my heart. I love breakfast foods! I think you’re getting the point.

Well, I’m here to tell you that this hash brown breakfast casserole is a delicious way to start the day. You can even make it an overnight breakfast casserole if you prefer by pre-assembling it the night before to bake the next morning.

This is one of those dishes that the entire family will enjoy and request again and again. A hash brown breakfast casserole is also great when you’re hosting guests or for your holiday breakfast.

Breakfast Casserole with Hash Browns

Doesn’t that look amazing, my friend? It really is so delicious! In this house, we love a few dashes of hot sauce with this cheesy hashbrown breakfast casserole.

Now, let me tell ya, if there is something that you or your littles don’t like, just leave it out. I understand that not everyone is fond of onions or red bell peppers. No need to cause anyone to have a melt down over breakfast. Lawd!

Personally, I love everything in this casserole and think that the red pepper gives it a nice kick of color. I’m all about “we eat with our eyes first“. Because it is true.

What to serve with hash brown breakfast casserole? The casserole is hearty and easily makes the entire meal itself but if you’re serving a larger crowd then consider also serving the casserole with a few more options.

Toasted bread with jam, biscuits, and fruit are great options. Don’t forget the beverages. Water, juice for a healthy dose of vitamin c first thing, coffee, or tea would be wonderful with this hashbrown casserole.

What is Breakfast Hash Brown Casserole Made Of?

breakfast bake ingredients for hashbrown breakfast casserole

Here’s what you’ll need to make this awesome baked casserole for breakfast:

  • Hash Brown Potatoes – I prefer the refrigerated (not frozen) shredded hash brown potatoes, like those from Simply Potatoes. The refrigerated hash browns make for easy breakfast recipes and there is no need to waste time waiting around for frozen potatoes to thaw.

Could you use something besides shredded hashbrowns? You could use the frozen hash brown patties or tater tots if that is what you have on hand.

  • Pork Sausage – I like to use the hot breakfast sausage from Jimmy Dean or Neese’s. Those are just two or our favorite brands but use whatever you prefer.
  • Red Bell Pepper – for texture, color and added flavor. Any color of sweet bell pepper would work just fine too.
  • Small Onion – I used a yellow onion for delicious added flavor in the casserole bake.
  • Cheddar Cheese – My preferred choice is extra sharp cheddar cheese because it adds that cheesy goodness and is one of my favorite things in a good breakfast casserole. Fresh grated cheeses are also my preference.

Do you have to use cheddar? (Reluctantly in a soft voice) no, you can use whatever you like. Monterey Jack, Pepper Jack, Colby Jack or whatever you like best would be fine too. Just add lots of cheese that makes you happiest.

  • Large Eggs – pastured eggs if you can get them are so flavorful and nutritious. 
  • Whole Milk – to help create the creamy eggs mixture.
  • Salt and Black Pepper – for seasoning.

Alternative or Optional Ingredients

Optional ingredients are sour cream or hot sauce for serving for those who want it and green onions for garnish.

I keep this breakfast bake simple with the seasonings and just use salt and pepper. You can add additional seasonings, of course, if you want. Garlic powder, onion powder or a pinch of cayenne pepper to give the morning casserole a kick would be great too.

Alternative ingredients that you may prefer include: turkey sausage or Italian sausage if you like those flavors better than the breakfast sausage.

Sausage, Egg & Cheese Hashbrown Breakfast Bake

I use a deep 9 x 13 baking dish for this recipe. Lightly spray the casserole dish with some non-stick cooking spray then add the shredded hash brown potatoes to form the bottom layer. 

To keep things simple, I just add the refrigerated hash browns as they are. If you really prefer crispy hash browns and want that texture in your casserole, then you can brown them in a large skillet over medium-high heat before adding to the baking dish.

The next step is to prepare the sausage mixture. Add the breakfast sausage to a skillet over medium heat and cook sausage until browned and crumbled.

Once the minced sausage has nearly cooked through, you can go ahead and add the onion and bell pepper, and allow it to cook until the sausage is done and the vegetables are tender.

Drain off any excess grease if necessary.

Next, use a large bowl to prepare the egg mixture. Crack the fresh egg into the bowl and add the milk, a teaspoon salt, ground black pepper; then use a whisk to combine eggs and seasonings with milk.

The recipe calls for eight eggs but you can easily add a whole dozen if you want to make the casserole a little bit fluffier and a bit more hearty.

Set the egg mixture aside for a moment to finish assembling the hash brown breakfast casserole.

Next, add the sausage mixture on top of the hash browns then top with the freshly grated cheese. 

Finally pour the egg mixture over the layers and pop the casserole into a pre-heated oven to bake until the eggs are set. It smells amazing as it bakes!

If you’re preparing this the night before, just cover the casserole with plastic wrap before baking and refrigerate overnight. The next morning you can bake it until done.

This is such an easy recipe and so versatile.

You must not be a Southerner. My family's been in Georgia since 1748 and I Charleston since 1680. Hash browns for breakfast? I never had potatoes for breakfast until I was drafted in 1970 on my way to Vietnam. I still refuse to eat potatoes for breakfast; it reminds me of the Army. No way, Jose! It's grits for me.

Rick, My family also started in Charleston in the 1600's and we are still in the state of South Carolina. What you eat for breakfast has nothing to do with being born Southern or not. I love grits and we eat them often. I do enjoy a variety of foods and share foods on my website that appeal to people who have different tastes in food. If this is not for you then it is not for you :) ~Julia
