Easy Crockpot Breakfast Casserole Recipe
Hash brown casseroles are always a crowd favorite. This one is super simple to make and I highly recommend cooking the sausage in advance so it can be assembled in minutes. Cooked breakfast sausage can be made and frozen for up to 3 months or until you need it for recipes such as this breakfast casserole. For this recipe, I cooked the sausage two days in advance and popped it into the refrigerator. It's a small step but a true time saver for assembling this in a few minutes.
How to Make the Best Crockpot Breakfast Casserole Recipe
- Ingredients you'll need to make homemade Crockpot Breakfast Casserole: 2 pounds cubed hash browns (if frozen, thawed) large eggs, shredded Colby jack or cheddar cheese, green onions, heavy cream, seasoned salt, black pepper, ground mustard, granulated garlic, onion powder and a few dashes of hot sauce.
- Kitchen tools you'll need: A large oval or round slow cooker (I used a 6 quart oval), medium bowl, whisk, measuring cups and spoons, sharp knife and chopping board and cheese grater.
- How do you make a Crockpot Breakfast Casserole? First, spray the crock of the slow cooker with cooking spray. Cook the breakfast sausage in a skillet until no pink remains, then drain of any excess fat. Press one third of the hash brown potatoes onto the bottom of the slow cooker. Top the hash browns with ½ of the cooked sausage and one half of the onions then sprinkle with 1 cup of shredded cheese. Repeat the layers, ending with hash browns. In a bowl, whisk together the eggs and seasonings with the heavy cream. Pour evenly over the top. After cooking, uncover and sprinkle the top with the remaining cup of shredded cheese then serve.
- How long do you cook Crock Pot Breakfast Casserole? Cover the slow cooker and cook on low for 6-8 hours or on high for 3-4 hours depending on how your appliance performs.
- It's fine if the hash browns are still partially frozen, don't sweat it, they will do fine.
- You may opt to use cubed ham, cooked chorizo or bacon in place of sausage.
- How do you know if the casserole is done? You can gently shake the crock pot to see if it's set. You can also check the center with a knife to see if the center is cooked through. The knife should be clean when removed.
- To serve this slow cooker breakfast casserole, you can cut it into pieces or scoop it out with a spoon.
- You can add diced red and green bell pepper or jalapeno pepper for added heat along with the green onions layer, if desired.
- You can use any flavor of shredded cheese that you enjoy in the same amount to change the flavor profile to your taste.
- Store cooked Crockpot Breakfast Casserole chilled in the refrigerator for up to 4 days. Reheat in single serving portions in the microwave.

This breakfast casserole was the best!! So tasty and easy to prepare. I tried your suggestion of cooking the sausage ahead of time (3 days ahead) and loved the convenience of doing that. Can you do that with ground beef also? Thank you for sharing this recipe.
I'm so happy you enjoyed it! Yes, you absolutely can and in fact, I brown ground beef in large batches and freeze it in portions that I think I'll need for a timesaver for future meals. Sausage, too! You can see how to do that here.
Very tasty! Took 4 hours on high in my Cuisinart crock pot. Nice change from boring breakfast casseroles.
Came out perfect! I looked through other similar recipes and all the comments were the same - tended to be bland, burnt, or dried out when overcooked. I settled on this one and I'm glad I did! I think using real Dijon instead of dried, season salt, heavy cream over milk and frozen over thawed hash browns all contributed to this turning out moist and flavorful. I was scared of overcooking so I did 3 hours on low followed by 2 more hours on high since my crockpot is brand new. Will make again!
Hi Jen, I'm so happy you enjoyed this, thank you!
Hi. I plan on making this for breakfast in the morning. I'm going to use turkey sausage and reduced fat cheese to lower the calories. Can I use 2% milk and place of the heavy cream? Do you think that would work? Thank you for the nice recipe.
Hi Bella, I haven't tested 2% milk in this recipe so I can't tell you with certainty. My thought is that it could result in a thinner sauce but that's not necessarily a bad thing. If you try it, let us know how it goes!
