Slow Cooker Breakfast Casserole

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 Hashbrown 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.
