Easy Crock Pot Breakfast Casserole

Slow Cooker Breakfast Casserole layers hash browns, sausage or ham, eggs, and a generous helping of cheese for an easy breakfast the entire family will love. Let this cook overnight in your Crock Pot or fix it in the morning, either way it's delicious!

I love easy recipes like this Crockpot breakfast casserole. It's perfect for holidays like Christmas morning when you don't want to cook, brunches, or sleepovers. You can let this casserole cook on low overnight or pop it in first thing in the morning to eat a few hours later.

Ingredients

Hash Browns - frozen shredded hash browns work best for this recipe. You can make it with diced potatoes as well but I've found that shredded has the best end result.
Meat - Make this with ground sausage, diced ham, or cooked and crumbled bacon, whichever you prefer! If making with diced ham or crumbled bacon I recommend adding some of the variations I list below the instructions to add more flavor.
Eggs - Use 10-12 eggs for this recipe, whipped up with some milk with a whisk. You can also use the equivalent amount of egg substitute if you prefer.
Cheese - I make this breakfast casserole with shredded sharp Cheddar cheese but feel free to experiment and try different varieties to change up the flavor!
Toppings - you can really get creative with toppings! I go simple with some chopped green onion most of the time but diced bell peppers, salsa, pico de gallo, sour cream are all delicious additions as well.

Step by step

Spray the crock pot with nonstick cooking spray or use a slow cooker liner.
Cook and crumble the meat in a large skillet if needed, set aside.
In your Crock Pot, layer frozen hash browns followed by meat. Pour the egg mixture over the top and then top with cheese.
Cook on low 7-8 hours or high 2 ½-3 hours.
Serve with your favorite toppings!
