If you want a simple slow cooker breakfast casserole recipe, you are going to love this one. This makes the best breakfast that makes it easy to eat a healthy breakfast before starting your day.

Can I Use Ham in this Breakfast Casserole?

The great think about this breakfast casserole is that you can make simple changes to make it a new recipe.  For this recipe, I used smoked sausage for the main protein.

If you prefer, this will work just as well with ham, sausage, or even bacon. You can even use chicken or chicken sausage if you have on hand. Also, don’t be afraid to load this with vegetables!   A few simple changes creates a whole new flavor.

Can This Cook on Low Overnight?

If you want to cook this overnight, you can cook it on low. It will take about 6-7 hours on low. This is a great way to have breakfast waiting for you when you get up in the morning.

Note: You may want to line your slow cooker or at least spray well with non-stick spray so that the potatoes don’t burn or get too crispy around the edges.

What is the Best Cheese for a Hash Brown Breakfast Casserole?

When I am making this hashbrown breakfast casserole, I like to use cheddar cheese. It is my favorite when it comes to this casserole. But just like you can change the flavor of the casserole by changing the proteins, you can also change this recipe by adding different cheese. You want to make sure you are using a cheese that melts well for the best results.

Other options that would be great are mozzarella, pepper jack cheese, or a cheese blend that includes cheddar and Colby.

  • Condensed cream of mushroom soup

How to Make a Crockpot Breakfast Casserole

To begin, you will need to simmer your cream of mushroom soup and milk together for a few minutes just to heat it through.

While that is heating, you will add the hash browns, sausage, and onions to the slow cooker with 1 cup of cheese.

Next, pour the sauce mixture over the top and stir until all of the casserole is combined.

You’ll top this with the remaining cheese and herbs then cover and cook as directed.

So good!5 stars

I felt very happy while reading this site. This was a really very informative site for me. I really liked it. This was really a cordial post. Thanks a lot!5 stars

I’m enjoying all these recipes and will be cooking some of these meals up very soon. Keep the free recipes coming. Thank you.

Great recipes

Sounds good, but I’m so relieved to see that the “Cranberry Lemon Zucchini” you suggested having with it in the description turned out to be BREAD!

Thanks for this great recipe! I will definitely try it. What do you think of using condensed cheese soup instead of Cream of Mushroom? I have a Crockpot Mac & Cheese recipe that uses the cheese soup and it is good with that. TIA for your feedback.

Hi Gloria! It will definitely be very cheesy! Let me know how it turns out.

What can you substitute for cream of mushroom? Allergic to mushrooms.

Hi Sara, I always sub cream of chicken if I don’t have cream of mushroom. That always works well.

I would use cream of bacon or cream of celery. personal choice

Sounds awesome but can you use breakfast sausage instead of smoked sausage. My family loves both but would prefer something like breakfast sausage instead of a kielbasa type of meat
