Overnight Breakfast Casserole That’s Not Mushy!

I love the ease of breakfast casseroles, but was never satisfied with them before because I think they are “mushy.” You know what I mean, right? I’m a texture gal. I can’t stand mushy textured food.

I think anything that resembles oatmeal is gross…and I have really tried to like it because I know it is so healthy and frugal – but I. Just. Can’t. Mushy stuff just doesn’t go down right.

Normally, I am not a fan of the breakfast casserole because of the texture. But, I attended a baby shower where this egg casserole was served and I loved it. I’m convinced that the difference is using potatoes instead of white bread. 

Have you had those breakfast casseroles made with bread? I always find them too mushy. I was originally skeptical about trying a new breakfast casserole, but potatoes make all the difference.

Overnight Breakfast Casserole with Hash Browns

Yes, potatoes! Every time I’ve used potatoes instead of bread, I am so happy with the resulting egg bake! So if you want an easy overnight breakfast casserole that’s not mushy, this recipe is for you!

Using potatoes instead of bread was a huge aha moment for me, and I haven’t looked back.

Here’s how to make a breakfast casserole that’s not mushy. It’s perfect for Christmas morning, brunch, or quick weeknight dinner!

cook sausage for the make ahead breakfast casserole

Brown sausage and spread in lightly greased 9 X 13 dish. I use my [easyazon_link identifier=”B0076NOSOS” locale=”US” tag=”sililo-20″]Le Creuset 5 qt braiser[/easyazon_link]. It’s nonstick, oven safe, and so pretty!

add potatoes to the breakfast casserole

Spread potatoes over sausage. Put the shredded cheddar cheese on top of the potatoes. Then, combine eggs, milk, salt, pepper in a large bowl, and pour over hash browns, sausage, and cheese.

add cheese before baking

At this point, cover and refrigerate overnight. The next morning, preheat the oven to 350 degrees. Sprinkle a little extra cheese on top, and bake uncovered at 350 degrees for 35 minutes or up to 45 minutes. Or, you can go ahead and cook it immediately too! Your call.

Questions about this Overnight Breakfast Casserole

Can I use ham or bacon instead of the sausage?

Absolutely! You can use any type of meat you want. We prefer sausage, but cooked crumbled bacon or 2 cups of leftover ham are also delicious in this egg casserole.

Do I have to refrigerate it overnight?

No, you don’t. You can make it up and cook it right away, if you want. I like to have it made in advance, but you certainly don’t have to.

Do I have to thaw the hash browns?

This comes down to personal preference. If you thaw your hash browns first, they won’t be as soggy. If you’d like them to be even more crispy, you can cook them a little bit prior to adding the other ingredients, but I almost never do this. 

How should I thaw the hash browns?

Ideally, you will thaw the hash browns by leaving them in your fridge overnight. The day you make up this casserole, dry them off a little bit with kitchen towels before adding them to the casserole dish. You can use paper towels if you prefer, but I eliminated paper towels from my kitchen years ago and haven’t looked back. Kitchen towels work just fine. 

Why don’t you mix the cheese in with the eggs?

Adding the cheese to the casserole separate from the egg mixture helps insure a more equal distribution of cheese throughout the casserole. You can mix the cheese in with your eggs if you don’t care about that. 🙂

What type of potatoes should I use in this easy breakfast casserole?

You can buy the pre-shredded bags of potatoes –  plain potatoes or potatoes with peppers and onions are also delicious. Remember to thaw frozen hash brown potatoes before making this recipe. You can also shred your own potatoes to use in this recipe if you want. Since I grow a lot of potatoes in my garden I am always looking

for ways to use them. If you shred your own potatoes, I recommend rinsing them and squeezing as much water out of them as you can.

Quick Question: recipe states to use cubed hash browns, not shredded, yet picture clearly shows shredded hash browns being used. Does it matter?

Sorry about that! You can use either. I updated the recipe to reflect that. :-)
